 This is a game of [Trictrac](https://en.wikipedia.org/wiki/Trictrac) rust implementation.
 
-The project is still on its early stages.
+The project is on its early stages.
+Rules (without "schools") are implemented, as well as a rudimentary terminal interface which allow you to play against a bot which plays randomly.
+
+Training of AI bots is the work in progress.
 
 ## Usage
 
-Install [devenv](https://devenv.sh/getting-started/), start a devenv shell `devenv shell`, and run the following commands.
-
-```bash
-# Run the relay server
-just build-relay
-just run-relay  # listens on :8080
-
-# Run the game (separate terminal)
-just dev
-```
-
-Open two browser windows at `http://127.0.0.1:9091`. In one, create a room; in the other, join with the same room name.
-
-Playing with the cli against the 'random' bot: `cargo run --bin=client_cli -- --bot random`
+`cargo run --bin=client_cli -- --bot random`
 
 ## Roadmap
 
 - [x] rules
 - [x] command line interface
 - [x] basic bot (random play)
-- [ ] web client (in progress)
-- [ ] network game (in progress)
 - [ ] AI bot
+- [ ] network game
+- [ ] web client
 
 ## Code structure
 
 - game rules and game state are implemented in the _store/_ folder.
-- the command-line application is implemented in _clients/cli/_; it allows you to play against a bot, or to have two bots play against each other
+- the command-line application is implemented in _client_cli/_; it allows you to play against a bot, or to have two bots play against each other
 - the bots algorithms and the training of their models are implemented in the _bot/_ and _spiel_bot_ folders.
 
 ### _store_ package
 
 The game state is defined by the `GameState` struct in _store/src/game.rs_. The `to_string_id()` method allows this state to be encoded compactly in a string (without the played moves history). For a more readable textual representation, the `fmt::Display` trait is implemented.
 
-### _clients/cli_ package
+### _client_cli_ package
 
-`clients/cli/src/game_runner.rs` contains the logic to make two bots play against each other.
+`client_cli/src/game_runner.rs` contains the logic to make two bots play against each other.
 
 ### _bot_ package
 
 - `bot/src/strategy/default.rs` contains the code for a basic bot strategy: it determines the list of valid moves (using the `get_possible_moves_sequences` method of `store::MoveRules`) and simply executes the first move in the list.
 - `bot/src/strategy/dqnburn.rs` is another bot strategy that uses a reinforcement learning trained model with the DQN algorithm via the burn library (<https://burn.dev/>).
 - `bot/scripts/trains.sh` allows you to train agents using different algorithms (DQN, PPO, SAC).
-
-### multiplayer game
-
-Packages "clients/backbone-lib", "clients/web/game", "server/protocol", "server/relay-server" are a Leptos-optimized adaptation of the macroquad-based [Carbonfreezer/multiplayer](https://github.com/Carbonfreezer/multiplayer) project. It is a multiplayer game system in Rust targeting browser-based board games compiled as WASM. The original project used Macroquad with a polling-based transport layer; this version replaces that with an async session API built for [Leptos](https://leptos.dev/).
-
-The system consists of:
-
-- A **relay server** (Axum/Tokio) that routes messages between players and manages rooms, without knowing anything about game rules.
-- A **backbone library** that handles WebSocket connection, handshake, and message routing, exposing an async API to the game frontend.
-- Game-specific **backend logic** implementing the `BackEndArchitecture` trait, which runs only on the hosting client.
-- A **Leptos frontend** that connects to a session and reacts to state updates.
-
-There is no dedicated game server. One of the players acts as the host: their browser runs the game backend locally. The relay server only forwards messages — it never touches game state.

-
-#### Data flow
-
-- **Actions** (e.g. "place stone at B3") flow from the UI to the host backend via `GameSession::send_action()`.
-- **State updates** flow back as `ViewStateUpdate::Full` (full snapshot, on join or reset) or `ViewStateUpdate::Incremental` (delta, for animations).
-- **Timers** are managed by the host's background task (wall-clock, no polling required from the game).
-
-#### backbone-lib session API
-
-The key design choice: `backbone-lib` owns a background async task per session. The Leptos app never drives a loop — it just awaits on events.
-
-#### Workspace
-
-**server/protocol**
-
-Shared message-type constants and the `JoinRequest` struct used during the WebSocket handshake.
-
-**server/relay-server**
-
-Listens on port 8080. Loads `GameConfig.json` on startup to know which games exist and their player limits:
-
-```json
-[{ "name": "trictrac", "max_players": 10 }]
-```
-
-Games can be added at runtime via the `/reload` endpoint. `/enlist` lists active rooms. A watchdog cleans up inactive rooms every 20 minutes.
-
-For production, put it behind a reverse proxy with SSL (the browser requires `wss://` on HTTPS pages). Example Caddy config:
-
-```
-your-domain.com {
-    handle_path /api/* {
-        reverse_proxy localhost:8080
-    }
-    file_server
-}
-```

+# Pourquoi le trictrac
+
+Je vais montrer pourquoi il faut redécouvrir le trictrac, pourquoi il pourrait être votre nouveau jeu favori. 
+Je vais montrer pourquoi il est intéressant, complexe pour les humains comme les machines.
+En quoi il diffère du backgammon de manière avantageuse. Pourquoi il a quasiment disparu.
+
+Le backgammon était connu à la grande époque du trictrac. Il ne lui manquait que le dé doubleur, apparu au début du XXe siècle, qui a ajouté les prises de décision méta, que le trictrac possèdait déjà sur plusieurs niveaux (via la gestion des bredouilles en fin de partie par exemple).
+
+Le hasard des dés permet au joueur faible d'espérer la victoire même en fin de partie (cf. Le tour du monde en 80 jeux).

-# client_web — UI/UX Design Proposals
-
-A structured critique of the current interface compared to the physical game, followed by concrete upgrade proposals. Organised from most impactful to most effort-intensive.
-
----
-
-## Aesthetic Direction
-
-**Concept: "18th-century French gaming salon"**
-
-The physical trictrac board is a piece of furniture — carved mahogany rails, felt or baize surface, ivory and ebony checkers, brass pegs in drilled holes, gilt scoring tokens. The online interface should feel like playing on that table under candlelight in a Parisian salon.
-
-- **Typography**: Pair a classical serif (e.g. [Cormorant Garamond](https://fonts.google.com/specimen/Cormorant+Garamond)) for headings and score readouts with a clean humanist sans (e.g. [Jost](https://fonts.google.com/specimen/Jost)) for UI controls and status text.
-- **Palette**: Forest green felt board (`#1d3d28`), alternating ivory (`#f0e6c8`) and deep burgundy (`#7a1e2a`) triangular fields, dark mahogany rails (`#2a1508`), aged parchment panels (`#f2e8d0`), gilt gold accents (`#c8a448`).
-- **Unforgettable detail**: Triangular fields (true *flèches*) rendered in CSS with a wood-grain body surrounding them.
-
----
-
-## 1. Board Shape: Rectangles → True Triangles
-
-**Current state**: Fields are 60×180px rectangles with a rounded corner. No backgammon/trictrac board looks like this.
-
-**Physical game**: Fields are elongated triangles (*flèches*) pointing from the rail toward the center bar, alternating two colors.
-
-**Proposal**: Replace `.field` `<div>` elements with SVG triangles, or use CSS `clip-path: polygon(50% 0%, 0% 100%, 100% 100%)` for bottom-row triangles and `clip-path: polygon(0% 0%, 100% 0%, 50% 100%)` for top-row triangles. The field background and checker stack become SVG foreignObject or positioned elements inside. This is a large structural change to `board.rs` but is the single highest-impact visual improvement.
-
-The board body between triangles becomes visible as the wood/felt surface — this naturally creates the physical board's "relief" without any extra decoration.
-
----
-
-## 2. Jan Zone Visual Identity
-
-**Current state**: The four quarters (small jan, big jan, return jan, last jan) are visually identical — same field color scheme, no labels or separation beyond the center bar.
-
-**Physical game**: Players must constantly know which quarter they are in because the rules differ radically per zone (forbidden jans, filling values, hit scoring values differ between small-jan-table and big-jan-table, corner position, exit zone).
-
-**Proposals**:
-
-### 2a. Zone labels
-Add thin labels (`"petit jan"`, `"grand jan"`, `"jan de retour"`) beneath the board-row (or as a subtle strip above/below the quarter). These should use the serif font at very small size and low opacity — decorative, not noisy.
-
-### 2b. Field color shift per zone
-The physical game uses alternating colors within each quarter, but different quarters can use slightly different base hues:
-- Small jan (fields 1–6): warm ivory / burgundy
-- Big jan / corner zone (fields 7–12): same, but field 12 gets a distinct "corner" treatment (see §4)
-- Return jan (fields 13–18): very subtly cooler ivory / dark teal instead of burgundy — signals "opponent's territory"
-- Last jan / exit (fields 19–24): subtly warmer, indicating checkers are "almost home"
-
-### 2c. Small-jan-table / big-jan-table highlight during hit scoring
-When a hit is being scored, briefly tint the entire table (fields 1–12 or 13–24) to make the point value distinction (4 pts vs 2 pts) spatially obvious. This fires as a 300ms flash synchronized with the scoring notification.
-
----
-
-## 3. Rest Corner (Field 12 / 13) Special Appearance
-
-**Current state**: Field 12 looks identical to field 11. Nothing indicates its unique rules (must enter/leave with 2 checkers simultaneously, cannot be landed on by a single checker).
-
-**Physical game**: The corner is a corner — it is literally in the corner of the table, a distinct physical location.
-
-**Proposals**:
-- Give field 12 (and 13 for Black) a **crown or arch shape** at the tip of the triangle, using a small SVG ornament.
-- Apply a **slightly warmer gold** field color to distinguish it.
-- When the player has two checkers there, show a subtle **lock icon** or a gilded ring around the checker stack to indicate "corner held."
-- When the corner is available to be taken *par puissance*, add a gentle pulsing outline on field 12 to indicate the privilege is available.
-- Tooltip or popover: on hover, show a brief note "Coin de repos — must enter and leave with 2 checkers."
-
----
-
-## 4. Checker Rendering: Static → Animated
-
-**Current state**: Checkers appear and disappear between `ViewState` snapshots. No movement animation.
-
-**Physical game**: Checkers slide across the board with a satisfying click sound.
-
-**Proposals**:
-
-### 4a. Slide animation
-Diff the board array between the previous and current `ViewState`. For each checker that moved from field A to field B, apply a CSS or Web Animation API translation from `field_center(A)` to `field_center(B)` (duration ~250ms, ease-out). This requires keeping the previous `ViewState` as state in `GameScreen` and computing a diff when a new state arrives.
-
-### 4b. Lift effect during staging
-When the player clicks an origin field and a checker becomes "selected," apply a `transform: scale(1.15) translateY(-4px)` with a subtle drop shadow increase. Visually lifts the checker off the board.
-
-### 4c. Checker appearance
-Replace the CSS `radial-gradient` circles with SVG:
-- **White**: ivory `#f5edd8` with a pearl sheen gradient, thin gilt ring border, engraved concentric circles
-- **Black**: ebony `#1a0f06` with subtle grain texture, same gilt ring
-
-A stack of 5+ checkers can render a "perspective stack" — each checker at a slight y offset with a shadow, giving depth.
-
----
-
-## 5. Dice: Static → Rolling Animation
-
-**Current state**: Dice appear with their final value immediately. No sense of randomness or anticipation.
-
-**Physical game**: Dice are shaken in a cup (*cornet*) and tumbled out. The roll is a theatrical moment.
-
-**Proposals**:
-
-### 5a. Roll animation
-When `SerTurnStage` transitions from `RollDice` to `Move`, animate both dice with a fast face-cycling (showing random faces for ~400ms, decelerating to final value). Pure CSS `animation` on the die-face SVG circles, cycling via `keyframes`.
-
-### 5b. Dice cups
-Add two SVG/CSS dice cups above the dice display. During rolling, they visually "tip" (rotate 90° via CSS transform) and the dice "fall out." A subtle translate-y on the dice moves them downward into view.
-
-### 5c. Double visual
-When both dice show the same value, add a subtle golden glow around both — visually communicating that it is a double (which affects scoring: 6 pts instead of 4, etc.).
-
-### 5d. Used-die visual
-When one die has been consumed by a staged move, slide it slightly down and reduce opacity (current: gray-out). Animate the "used" transition with `transition: all 0.15s`.
-
----
-
-## 6. Scoring Notifications: Side Panel → Layered Toasts
-
-**Current state**: Scoring events appear as a small cream panel in the side panel column (`scoring-panel`). They are easily missed, especially opponent events.
-
-**Physical game**: Scoring is the central drama of every turn — points are loudly marked, bredouille doubled, holes recorded with pegs.
-
-**Proposals**:
-
-### 6a. Board-overlaid toast for holes
-When a hole is won, display a large centered overlay on the board — not a modal, but a translucent toast with gilt border: `"Trou ! ×2 bredouille"`. Auto-dismiss after 1.5s or on click. This is the most important event and deserves the most visual weight.
-
-### 6b. Scoring event animation
-When `my_scored_event` appears, animate the panel sliding in from the right with a 200ms ease-out. Jan rows stagger in (each with `animation-delay: n * 50ms`).
-
-### 6c. Jan hover → board highlight synchronization
-The current arrow-on-hover feature is good. Extend it: when hovering a jan row, also highlight the relevant fields with a faint golden shimmer instead of (or in addition to) the arrows. This ties the abstract jan name to a concrete board location.
-
-### 6d. Bredouille treatment
-Bredouille doubles a hole's value — a massive game event. Currently shown as a small amber badge. Proposals:
-- The toast for a bredouille hole should animate in differently: bigger, gold shimmer background
-- Show a small animated flag (*pavillon*) icon in the score panel when bredouille is active, matching the physical game's token
-
-### 6e. Hit scoring visual
-When a hit is scored (*battue*), show a brief visual on the opponent's half-field checker — a faint concentric ring expanding outward (CSS `animation: ripple 0.4s ease-out`). This communicates the "fictitious" nature of the hit: something happened at that checker's position, but it didn't move.
-
----
-
-## 7. Score Panel: Progress Bars → Pegs and Holes
-
-**Current state**: Points and holes are displayed as progress bars (0–12) and numeric values. Functional but abstract.
-
-**Physical game**: Points are tracked with physical tokens (*jetons*) placed on the board surface at specific field tips. Holes are tracked with pegs (*fichets*) in holes drilled along the rail at each field base.
-
-**Proposals**:
-
-### 7a. Hole tracker: 12 dots/pegs
-Replace the `score-bar-holes` progress bar with a row of 12 small circles ("drilled holes") in a horizontal strip. Filled holes are rendered as a gilded peg inserted (solid gold circle). Unfilled holes are empty rings. This is a `<svg>` with 12 `<circle>` elements. The filled count animates one peg at a time (sequenced `animation-delay`).
-
-### 7b. Point tracker: token on board
-For points (0–11), show a small token image positioned at the corresponding field tip along the near rail — mirroring the physical game exactly. This is ambitious but highly authentic. A simpler approach: replace the thin progress bar with a 12-cell dot track where one glowing token is positioned.
-
-### 7c. Bredouille indicator
-When `can_bredouille` is true for a player, show the token as a double-token (two stacked icons) or add a small flag icon next to the token.
-
----
-
-## 8. Status Communication: Text → Contextual Guidance
-
-**Current state**: A single text line (`"Select move 1"`, `"Opponent's turn"`) in the status bar. New players have no idea what to do or why they can't do something.
-
-**Physical game**: Human players narrate what's happening; experienced players understand the state from context.
-
-**Proposals**:
-
-### 8a. Contextual sub-prompt
-Below the primary status, show a secondary hint line in smaller text:
-- During `Move` stage: `"Click a highlighted field to move a checker"`
-- During `HoldOrGoChoice`: `"Hold to keep points and keep playing — Go to reset and start a new setting"`
-- When waiting for confirm: `"↑ Opponent scored points — click Continue when ready"`
-
-### 8b. Forbidden-jan visual cue
-When a field is in the opponent's jan and the player cannot land there (forbidden jan rule), show those fields with a subtle `✕` pattern or darker tint rather than just being unclickable. This communicates *why* the fields aren't selectable.
-
-### 8c. Exit-eligible highlight
-When all player checkers are in the last jan (fields 19–24), add a subtle directional glow to the exit rail (the right/left edge of the board depending on player). A small "EXIT →" arrow indicator could appear.
-
-### 8d. Can-take-corner indicator
-When the player can take their corner (field 12 or 13 is the valid destination), add a brief pulse to that field beyond the standard `.dest` highlight — the corner rules are special enough to warrant extra visual salience.
-
----
-
-## 9. Bug Fix: Hold Button Is Non-Functional
-
-**File**: `src/components/scoring.rs` line 91
-
-The "Hold" button in the `ScoringPanel` has no `on:click` handler. In the physical game, "Hold" (*tenir*) means: stay in the current setting, mark remainder points, and continue playing normally.
-
-`PlayerAction` does not currently include a `Hold` variant. In the current implementation, if the player simply does nothing (doesn't click Go), the game waits — but there is no message sent to the backend to confirm "staying."
-
-**Fix required**: Add `PlayerAction::Hold` (or reuse `Mark`) and connect the Hold button's `on:click` to send it. The backend needs to handle it by advancing past `HoldOrGoChoice` without triggering `GameEvent::Go`.
-
----
-
-## 10. Layout: Side Panel → Integrated Design
-
-**Current state**: The board and side panel sit side-by-side (`board-and-panel: flex-direction row`). The side panel (min-width 160px) contains status, dice, scoring, and buttons stacked vertically.
-
-**Proposals**:
-
-### 10a. Move dice inside the board
-Place the dice display centered in the **board-bar** (the vertical divider between quarters). Currently the bar is 20px wide — widen it to ~80px and center two dice there. This puts dice physically near the board action, matching the physical game where dice land on the board surface. The bar color becomes a darker felt strip.
-
-### 10b. Status bar above the board
-Move the primary status message to a full-width strip directly above the board, styled with the serif font at larger size. This gives it appropriate visual weight and removes it from the cramped side panel.
-
-### 10c. Action buttons below the board (or in score panels)
-"Continue," "Go," and "Hold" buttons can live below the board in a centered button row. The side panel then becomes purely informational (scoring panels), which can slide in from the right.
-
-### 10d. Mobile: rotate board 90° option
-The board is ~776px wide. On narrow screens, offer a portrait mode where the board is rendered rotated 90° (each player's quarters stacked vertically), with a scroll-independent panel above/below for controls.
-
----
-
-## 11. Login Screen: Form → Atmosphere
-
-**Current state**: A plain 320px-wide column with a `<h1>Trictrac</h1>`, a text input, and three buttons. Functional but gives no sense of what the game is.
-
-**Physical game**: A trictrac board is an object of beauty — players set it out, prepare the checkers, and roll for first-move privilege.
-
-**Proposals**:
-
-### 11a. Illustrated header
-A high-quality SVG illustration of the board (simplified top-down view, showing the triangular fields, checker stacks at starting positions, dice) as the page hero. Possibly animated: the two stacks slowly deploying two checkers as the page loads.
-
-### 11b. Typography treatment
-"TRICTRAC" as a large display heading in a classical-weight serif, possibly with subtle tracking and a gilt color. Below it, the French subtitle: *"Jeu de trictrac — XVIIIe siècle"* in small-caps at reduced opacity.
-
-### 11c. Mode selection
-The three buttons (Create / Join / vs Bot) styled as wooden tiles or embossed cards rather than plain buttons.
-
----
-
-## 12. Game-Over Modal: Generic → Ceremonial
-
-**Current state**: A centered modal with "Game Over," the winner's name, and Quit/Play Again buttons.
-
-**Physical game**: The end of a game involves settling accounts, noting the final hole count, and potentially recording results.
-
-**Proposals**:
-- Show a **final score parchment** — both players' hole counts displayed like a ledger entry, with the winner's name engraved in gilt text
-- Animate the modal entrance with a slight downward reveal (the parchment "unrolling")
-- Show the hole difference: `"8 — 3"` in large numerals with a small flourish between them
-- If bredouille applied to the winning holes: `"✕ 2 bredouille"` annotation
-- "Play again" styled as "Rejouer" / "Play again" with a dice icon

-# client_web — Alternative Design Proposals: Neon Arcade Future
-
-A second aesthetic direction: bold, playful, unapologetically modern. Where the first proposal channels an 18th-century gaming salon, this one asks: *what if trictrac ran on a holographic table in a Tokyo arcade, 2089?*
-
-This document proposes a complete visual redesign with no obligation to mirror physical game objects. The priority is delight, readability, and memorability.
-
----
-
-## Aesthetic Direction: "Holographic Arcade"
-
-**Core concept**: The board floats in dark space as a self-illuminated slab. Fields pulse with neon light. Checkers are luminous marbles that leave light trails as they move. Scoring events trigger particle explosions. Every interaction has a micro-animation.
-
-**The one unforgettable thing**: When a hole is won, the entire board floods with a colour wave — a full-screen shimmer that fades in 800ms — like a pinball machine tilting into multiball.
-
-**Color palette**: Built on darkness, with high-saturation accents — cyan, magenta, gold. Not gradients on white (the generic AI aesthetic); instead, near-black backgrounds with glowing, luminous elements.
-
-**Typography**: [Space Grotesk](https://fonts.google.com/specimen/Space+Grotesk) is overused. Instead:
-- Display: [Syne](https://fonts.google.com/specimen/Syne) — geometric, confident, slightly alien
-- Numerics: [DM Mono](https://fonts.google.com/specimen/DM+Mono) — for scores, dice values, field numbers — crisp monospace with personality
-- UI labels: [Outfit](https://fonts.google.com/specimen/Outfit) — friendly, modern, clear at small sizes
-
-```css
-:root {
-  /* Base */
-  --void:           #09090f;        /* near-black with blue tint */

-}
-```
-
----
-
-## 1. Board: A Floating Holographic Slab
-
-**Concept**: The board is a dark rectangular surface that appears to float — slight perspective tilt (CSS `perspective` + `rotateX(3deg)`), a thin neon border (1px cyan on top, 1px dimmer on bottom for depth), and a subtle inner glow that makes the board feel luminous from within.
-
-```css
-.board {
-  background: var(--surface);
-  border: 1px solid var(--cyan-dim);
-  box-shadow:
-    0 0 0 1px rgba(0,229,255,0.1),
-    0 0 40px rgba(0,229,255,0.08),
-    0 24px 60px rgba(0,0,0,0.8);
-  transform: perspective(1200px) rotateX(2deg);
-  transform-origin: center bottom;
-  border-radius: 4px;
-}
-```
-
-The board background gets a very subtle **noise texture overlay** (SVG `<feTurbulence>` or a PNG grain layer at 3% opacity) — just enough to prevent it from looking like a flat rectangle, giving it material presence.
-
-The center bar and side bars become **glowing dividers**: 4px wide, gradient from `var(--cyan)` at top to `var(--magenta)` at bottom, with a matching glow.
-
----
-
-## 2. Fields: Neon Triangles with Zone Color Identity
-
-Triangular fields (CSS `clip-path: polygon`) are essential here — they're geometric and modern, not just historically authentic.
-
-Each quarter gets its **own neon color identity**, using a very dark base with a glowing triangle border:
-
-| Quarter | Fields | Primary accent | Secondary (alternating) |
-|---------|--------|---------------|------------------------|
-| Small jan | 1–6 | `#00e5ff` (cyan) | `#0077aa` (dim cyan) |
-| Big jan | 7–12 | `#7c4dff` (violet) | `#4a2a99` (dim violet) |
-| Return jan | 13–18 | `#e040fb` (magenta) | `#991a99` (dim magenta) |
-| Last jan | 19–24 | `#ffd740` (gold) | `#aa8800` (dim gold) |
-
-The field itself is dark (`#14141f`). The color lives in a **glowing triangle border** — achieved with a layered `clip-path` + `::before` pseudo-element 2px larger that shows through as the border, with a CSS `filter: blur(3px)` outer glow:
-
-```css
-.field {
-  background: #14141f;
-  clip-path: polygon(50% 0%, 0% 100%, 100% 100%);
-  position: relative;
-}
-.field::before {
-  content: '';
-  position: absolute;
-  inset: -2px;
-  background: var(--field-accent-color);
-  clip-path: polygon(50% 0%, 0% 100%, 100% 100%);
-  filter: blur(4px);
-  opacity: 0.4;
-  z-index: -1;
-}
-```
-
-**On hover (clickable fields)**: the glow intensifies (`opacity: 0.9`, `filter: blur(6px)`) and the field interior lightens slightly. A ripple animation radiates outward from the click point.
-
-**Selected field**: the entire field interior fills with a semi-transparent neon color — not just the border — and a 2px dashed animated border spins around it (`animation: spin-border 1s linear infinite`).
-
----
-
-## 3. Checkers: Luminous Marbles
-
-Forget CSS circles with radial gradients. Each checker is a **glowing orb** with:
-
-- A dark, slightly translucent core
-- A radial highlight in the upper-left (simulating a point light source)
-- A colored halo that radiates outward onto the field triangle
-- A subtle inner reflection ring
-
-```css
-.checker.white {
-  background: radial-gradient(circle at 35% 30%,
-    #ffffff,
-    #c8c0e0 40%,
-    #8878c0 70%,
-    #3a2a60
-  );
-  box-shadow:
-    inset 0 2px 6px rgba(255,255,255,0.8),
-    inset 0 -2px 4px rgba(0,0,0,0.4),
-    0 0 12px rgba(179,157,219,0.6),   /* violet-white glow */
-    0 0 24px rgba(124,77,255,0.3);    /* outer violet halo */
-}
-
-.checker.black {
-  background: radial-gradient(circle at 35% 30%,
-    #7c4dff,
-    #4a2d99 40%,
-    #1a0a40 70%,
-    #09040f
-  );
-  box-shadow:
-    inset 0 2px 6px rgba(124,77,255,0.5),
-    inset 0 -2px 4px rgba(0,0,0,0.8),
-    0 0 12px rgba(124,77,255,0.7),
-    0 0 24px rgba(124,77,255,0.3);
-}
-```
-
-**Stack depth**: A stack of N checkers renders with each checker offset by 6px vertically and slightly scaled (0.97× per level deeper), creating genuine 3D stack depth without any 3D CSS transform. The count label floats above as a monospace number in `var(--gold)`.
-
-**Selection animation**: On click to select, the top checker of the stack does a quick `scale(1.2) translateY(-8px)` bounce (150ms spring easing), then settles at `scale(1.1) translateY(-4px)` while selected.
-
-**Movement animation**: When a move is confirmed (board state diff), selected checkers do a **light-trail arc** — a bezier path from origin field center to destination, with a fading cyan streak left behind (`box-shadow` animated along the path via `@property` interpolation or JS Web Animation API). Duration: 300ms.
-
----
-
-## 4. Dice: Holographic Crystals
-
-Replace the SVG ivory dice with **translucent crystal cubes**:
-
-- Each die face is a dark glass square with a thin neon border
-- Pips are glowing dots — cyan for normal, gold for doubles
-- The die face has a subtle `backdrop-filter: blur(4px)` on a glass background
-
-```css
-.die-face rect {
-  fill: rgba(255, 255, 255, 0.04);
-  stroke: var(--cyan);
-  stroke-width: 1.5;
-  rx: 6;
-  filter: drop-shadow(0 0 6px var(--cyan));
-}
-.die-face circle {
-  fill: var(--cyan);
-  filter: drop-shadow(0 0 4px var(--cyan));
-}
-```
-
-**Double dice**: Both pips and borders switch to `var(--gold)`, with a stronger glow (`drop-shadow(0 0 8px var(--gold))`).
-
-**Roll animation**: 600ms sequence —
-1. Both dice **shatter outward** (`scale(0) rotate(720deg)`, opacity 0 → 1) appearing from nothing
-2. During 400ms they rapidly cycle through face values (random pips swap every 60ms via CSS `animation`)
-3. Final 200ms they decelerate and **snap** to the rolled values with a brief flash pulse
-
-**Used die**: Fades the border to `rgba(255,255,255,0.1)` and dims pips to `rgba(255,255,255,0.2)` — the die goes "offline." A thin strikethrough line appears diagonally.
-
----
-
-## 5. The Hole Tracker: Orbital Rings
-
-Instead of progress bars, score and hole progress are visualised as **concentric orbital rings** beside each player's name panel — inspired by loading spinners, but static and data-driven.
-
-- **Outer ring** (thick, 6px): hole progress. 12 segments, each one lights up as a hole is won. Segments are `var(--gold)` when won, near-invisible dark when empty.
-- **Inner ring** (thin, 3px): point progress within the current hole. Continuously filled arc from 0° to (points/12 × 360°). Color: `var(--cyan)` for the active player, `var(--magenta)` for the opponent.
-
-The arc fills animate with `stroke-dashoffset` transition (0.4s ease-out) on every point gain.
-
-**Bredouille state**: The outer ring segments pulse — a slow `opacity: 0.6 → 1 → 0.6` sinusoidal glow — as long as bredouille is active. A small flag icon (⚑) in `var(--gold)` appears beside the ring.
-
----
-
-## 6. Scoring Events: Light Shows
-
-### Hole won — Full-board colour wave
-A `position:fixed` `::after` overlay expands from the scoring player's side of the board:
-- Radial gradient expanding from one edge: `rgba(255,215,64,0)` → `rgba(255,215,64,0.15)` → `rgba(255,215,64,0)`
-- Duration: 800ms, ease-in-out
-- Simultaneously: the scoring player's orbital rings segments animate sequentially (each segment snaps on with a 50ms delay)
-- A large centered text `"+1 TROU"` in `var(--font-display)` at 3rem scales from 60% to 110% with `opacity: 0 → 1 → 0`, duration 1.2s
-
-### Bredouille — The cascade
-On top of the hole wave, add:
-- A **confetti burst** of small colored squares (pure CSS: 20 `<span>` elements with randomised `animation-delay` and `translate`/`rotate` keyframes) in cyan, magenta, gold
-- The `"+1 TROU"` text instead reads `"BREDOUILLE ×2"` in `var(--magenta)`
-- The board border flashes: `border-color` cycles cyan → magenta → gold → cyan over 0.6s
-
-### Jan scored — Notification card
-Each jan scored gets a **toast card** that slides in from the right edge:
-- Dark glass background (`rgba(26,26,46,0.95)`) with a left border in the jan's quarter color
-- Jan name in `var(--font-ui)` bold, points in `var(--font-mono)` large
-- Progress: `"+4 pts"` in cyan, `"+6 pts (double)"` in gold
-- Cards stack vertically if multiple jans fire; each staggered by 80ms
-- Auto-dismiss with a rightward slide-out after 3s
-
-### Hit scored — Ripple on the target checker
-When a hit is scored on a specific field, that field's checker emits a **sonar ripple**:
-- 3 concentric rings expand from the checker's center, each `opacity: 1 → 0, scale: 1 → 2.5`
-- Color: cyan for true hits, magenta for false hits (giving to opponent)
-- Duration: 600ms per ring, staggered by 200ms
-
----
-
-## 7. Player Panels: Glassmorphism Cards
-
-Replace the cream `background: #f5edd8` panels with **glass cards** floating above the void:
-
-```css
-.player-score-panel {
-  background: rgba(255, 255, 255, 0.04);
-  border: 1px solid rgba(255, 255, 255, 0.1);
-  border-top: 1px solid rgba(255, 255, 255, 0.2); /* top catches light */
-  backdrop-filter: blur(12px) saturate(1.5);
-  border-radius: 12px;
-  box-shadow:
-    0 8px 32px rgba(0, 0, 0, 0.4),
-    inset 0 1px 0 rgba(255, 255, 255, 0.08);
-}
-```
-
-**Active player panel**: the border glow of the active player's card brightens: `border-color: var(--cyan)` with `box-shadow: 0 0 16px rgba(0,229,255,0.2)`. A tiny animated pulse on the left edge (`width: 3px, animation: pulse 1.5s ease-in-out infinite`) indicates it is their turn.
-
-**Player name**: Displayed in `var(--font-display)` at 1.1rem. A small colored dot (cyan for player 1, magenta for player 2) precedes the name — acts as the "you" indicator without needing a text suffix.
-
----
-
-## 8. Status Bar: Dynamic Ambient Messaging
-
-Replace the single plain-text status line with a **contextual bar** that changes character per game stage:
-
-| Stage | Style | Color |
-|-------|-------|-------|
-| Waiting for opponent | Slow pulsing dots animation `... ` | Dim white |
-| Your turn (roll) | "YOUR MOVE" in `var(--font-display)` with a blinking cursor | Cyan |
-| Opponent's turn | Subtle shimmer on text | Dim magenta |
-| Move selection | "SELECT CHECKER ①" with animated underline on "SELECT" | Cyan |
-| Hold or Go | "SCORE!" with a spinning star ✦ | Gold |
-| Paused (continue) | The bar has a pulsing amber background strip | Amber |
-| Game over | Text cycles through all player colors | Full rainbow |
-
-The bar itself is 3px tall and spans the full board width, showing a **neon progress shimmer** during the opponent's turn (a traveling gleam, like CSS `animation: shimmer` on a gradient).
-
----
-
-## 9. Jan Zone Awareness: Neon Underlay
-
-Rather than labels, the four quarters glow with their zone color in the background of the board — very subtle, just 4% opacity fills under the triangles:
-
-```css
-.board-quarter-small-jan  { background: rgba(0, 229, 255, 0.04); }
-.board-quarter-big-jan    { background: rgba(124, 77, 255, 0.04); }
-.board-quarter-return-jan { background: rgba(224, 64, 251, 0.04); }
-.board-quarter-last-jan   { background: rgba(255, 215, 64, 0.04); }
-```
-
-When hovering a scoring-notification row that references a specific jan (e.g. "Big jan conserved"), the corresponding quarter's background pulses from 4% → 15% opacity for 600ms. This replaces the arrow overlay with a spatial, zone-level highlight — more legible and visually coherent.
-
----
-
-## 10. Rest Corner: The Crown Field
-
-Field 12 (White) and 13 (Black) get a distinct appearance:
-
-- The triangle is outlined in `var(--gold)` instead of its quarter's color
-- A small **crown SVG** (⚜ or ♛) floats centered in the triangle at 30% opacity when empty, brighter when held
-- When the player holds the corner (2 checkers there), the triangle interior fills with a very subtle gold shimmer animation (`background-position: 0% → 100%` on a diagonal gradient, 2s loop)
-- When the corner is available to be taken *par puissance*, the crown pulses at 1Hz
-
----
-
-## 11. Login Screen: Warp Speed Entrance
-
-**Hero**: A dark void with an animated **particle field** — small white/cyan dots drifting slowly, like stars. Pure CSS with 50 `<span>` elements (or a single `<canvas>` for performance), each with randomised `animation-delay` and drift keyframe.
-
-**Title**: "TRICTRAC" in `var(--font-display)` at 5rem, with a **chromatic aberration effect** — three slightly offset copies in cyan, magenta, and white, blended with `mix-blend-mode: screen`. The word appears with a `clip-path: inset(100% 0 0 0) → inset(0% 0 0 0)` reveal animation (the text "rises" into view).
-
-**Tagline**: `"XVIIIe siècle · En ligne · ∞"` in `var(--font-mono)` at 0.85rem, appearing letter-by-letter with a 20ms interval.
-
-**Mode cards**: Instead of three buttons, three **holographic tiles** in a row:
-- Each is a glass card with an icon, label, and a colored accent strip on the bottom
-- On hover: the card lifts (`translateY(-4px)`) and the bottom strip color floods the card (low opacity fill)
-- CREATE: cyan accent; JOIN: violet accent; vs BOT: orange accent
-
-**Room code input**: Dark glass input with a cyan border glow on focus, monospace font for the code, no placeholder text (just a blinking cursor showing it's ready). The input border animates a traveling gleam on focus.
-
----
-
-## 12. Game-Over Screen: Score Reveal Ceremony
-
-Instead of a modal over a frozen game, the game-over sequence is a **full-page takeover**:
-
-1. **Board fades out** (800ms fade): the board dims to 20% opacity
-2. **Score card rises** from the bottom: a tall glass card with both players' hole counts displayed large in `var(--font-display)` — `"8"` vs `"3"` — in their respective colors
-3. **Winner highlight**: the winning number scales up to 200% with a gold burst radiation behind it
-4. **Bredouille annotation**: if applicable, `"× 2"` appears beside the number with a magenta glow, then the number updates to the effective doubled count
-5. **Continue options**: two buttons slide up last — "QUIT" and "REJOUER" — with the rejouer button pulsing in cyan
-
----
-
-## 13. Global Micro-Interactions
-
-These apply throughout and give the interface a consistently tactile feel:
-
-- **Button press**: `scale(0.96)` on `:active`, 80ms, then spring back. No `opacity` change — scale is more physical.
-- **Button focus**: neon outline ring animated in from 0 to full radius (not the browser default outline).
-- **Panel hover**: glass cards shift `box-shadow` slightly for a lifted feel.
-- **Page load**: all elements stagger in with a `translateY(10px) → 0 + opacity 0 → 1`, each component with a `animation-delay` offset (board: 0ms, panels: 100ms, side panel: 200ms).
-- **Custom cursor** (optional): replace the default cursor with a small circle that trails slightly behind the real cursor position — creates a luxurious "lag" feeling. Pure JS: interpolate cursor position toward mouse position at 80% each frame.
-
----
-
-## Implementation Notes for Leptos/WASM
-
-### What's straightforward in pure CSS
-- All color variables, glass panels, glow effects, orbital rings (SVG `stroke-dashoffset`)
-- Dice roll animation (CSS keyframes)
-- Toast slide-ins (CSS `@keyframes` + `animation`)
-- Confetti (CSS `@keyframes` on positioned `<div>` elements)
-- Particle field on login (CSS-only with many `<span>` elements)
-
-### What needs a small JS/WASM component
-- **Board perspective tilt** with mouse-tracking (subtle parallax) — `mouse_position` signal driving CSS custom property
-- **Checker light-trail movement** — needs previous/next board diff, then Web Animation API or `requestAnimationFrame`
-- **Chromatic aberration on title** — CSS filter or SVG filter, but the animation needs JS timing
-
-### What needs Rust/Leptos state
-- **Board diff for animation**: store previous `[i8; 24]` alongside current in `GameScreen` as a `Memo`, compute moved checkers
-- **Event timing for sequences**: hole-won wave → score reveal → dismiss must be orchestrated; a `RwSignal<Option<AnimationState>>` in `GameScreen` drives each phase
-
-### Progressive approach
-The proposals above can be adopted incrementally. Suggested order:
-1. CSS variables + dark theme + Syne/DM Mono fonts → immediate impact, zero logic change
-2. Glass panels, neon borders, glow effects → pure CSS
-3. Orbital ring score tracker → SVG component
-4. Triangular fields + zone colors → `board.rs` structural change
-5. Dice animation → CSS keyframes in `die.rs`
-6. Toast notifications → new `toast.rs` component
-7. Hole-won wave → CSS overlay + Leptos signal
-8. Checker animation → board diff + Web Animation API

-                                    └──(reconnect)─────┘
-Playing ──(disconnect / game over)──→ Login
-```
-
-`app.rs` drives transitions via `RwSignal<Screen>`.
-
----
-
-## State Management
-
-### Root signals (live in `App`, provided via Leptos context)
-
-| Signal | Type | Purpose |
-|--------|------|---------|
-| `screen` | `RwSignal<Screen>` | Which screen is shown |
-| `pending` | `RwSignal<VecDeque<GameUiState>>` | Buffered states awaiting "Continue" |
-| `cmd_tx` | `UnboundedSender<NetCommand>` | UI → network command channel |
-
-Both `pending` and `cmd_tx` are provided as context so any descendant can read/write them without prop-drilling.
-
-### GameScreen-local signals
-
-| Signal | Type | Purpose |
-|--------|------|---------|
-| `selected_origin` | `RwSignal<Option<u8>>` | First clicked field during move staging |
-| `staged_moves` | `RwSignal<Vec<(u8, u8)>>` | Accumulated (origin, dest) pairs for this turn |
-| `hovered_jan_moves` | `RwSignal<Vec<(CheckerMove, CheckerMove)>>` | Moves to draw arrows for on hover |
-
-### Data flow
-
-```
-Network task (async in App)
-    ↓  SessionEvent::Update
-push_or_show() → pending queue or screen.set()
-    ↓
-GameScreen re-renders (GameUiState prop)
-    ↓
-User clicks field → staged_moves effect → NetCommand::Action(Move)
-User clicks Go/Continue → cmd_tx.send or pending.pop_front()
-```
-
----
-
-## Network and Session
-
-The multiplayer layer is provided by `backbone-lib` (local fork at `../../forks/multiplayer/`). `App` spawns an async task (via `spawn_local`) that multiplexes:
-- `cmd_rx`: commands from UI components
-- `session.next_event()`: updates from the server
-
-### StoredSession (localStorage key: `"trictrac_session"`)
-
-```rust
-struct StoredSession {
-    relay_url: String,
-    game_id: String,
-    room_id: String,
-    token: u64,          // reconnect token issued by server
-    is_host: bool,
-    view_state: Option<ViewState>,  // host saves last known state; guest saves None
-}
-```
-
-On page load, if a stored session exists, App goes directly to Connecting and sends `NetCommand::Reconnect`. Failed reconnects clear the session and return to Login.
-
----
-
-## Pause / Confirmation Flow
-
-Certain opponent events are paused so the local player can see what happened before their turn starts.
-
-Pause triggers (`infer_pause_reason()` in `app.rs`):
-
-| Reason | Condition |
-|--------|-----------|
-| `AfterOpponentRoll` | Opponent is active; dice values changed |
-| `AfterOpponentGo` | Opponent chose Go (HoldOrGoChoice→Move transition) |
-| `AfterOpponentMove` | Turn switched to us |
-
-While a state is in the pending queue, `GameScreen` shows a "Continue" button. Clicking it calls `pending.pop_front()`; if the queue empties, the live state is displayed.
-
----
-
-## Game Engine Integration
-
-**File**: `src/trictrac/backend.rs`
-
-`TrictracBackend` implements the `BackEndArchitecture` trait. It owns a `GameState` from `trictrac-store` and translates between the UI protocol and the engine's event model.
-
-### PlayerAction → GameEvent mapping
-
-| PlayerAction | GameEvents emitted |
-|---|---|
-| `Roll` | `GameEvent::Roll`, `GameEvent::RollResult(d1, d2)` |
-| `Move(m1, m2)` | `GameEvent::Move` (after validation) |
-| `Go` | `GameEvent::Go` |
-| `Mark` | internal; drives `MarkPoints`/`MarkAdvPoints` loop automatically |
-
-`drive_automatic_stages()` loops through scoring stages without waiting for player input — these are not interactive in the current implementation (schools are not implemented).
-
-### ViewState construction
-
-`ViewState::from_game_state()` in `types.rs` converts the engine state to the serialisable snapshot sent to clients:
-- `board: [i8; 24]` — direct copy of `Board::positions`
-- `dice: [u8; 2]` — current dice values
-- `stage / turn_stage` — serialisable enums (`SerStage`, `SerTurnStage`)
-- `scores: [PlayerScore; 2]` — points, holes, `can_bredouille`
-- `dice_jans: Vec<JanEntry>` — scoring events for the current turn, sorted descending by points
-- `active_player_index: usize` — 0 = host, 1 = guest
-
-### Bot
-
-`bot_local.rs` runs in the browser (no server call). It inspects `GameState` directly and returns a `PlayerAction`:
-- **RollDice**: always Roll
-- **HoldOrGoChoice**: always Go
-- **Move**: picks a random legal sequence from `MoveRules::get_possible_moves_sequences()`; mirrors moves because Black's board is mirrored
-
----
-
-## Board Rendering (`board.rs`)
-
-### Layout
-
-The 24 fields are split into 4 quarters of 6. Each player sees the board from their own perspective:
-
-```
-White's view:
-  TOP-LEFT  [13–18]  |  TOP-RIGHT  [19–24]
-  ─────────────────────────────────────────
-  BOT-LEFT  [12–7]   |  BOT-RIGHT  [6–1]
-
-Black's view (mirror):
-  TOP-LEFT  [1–6]    |  TOP-RIGHT  [7–12]
-  ─────────────────────────────────────────
-  BOT-LEFT  [24–19]  |  BOT-RIGHT  [18–13]
-```
-
-Fields are 60 × 180 px, alternating gold (`#d4a843` / `#c49030`). Checkers are 40 px SVG circles (radial gradient). Up to 4 are stacked visually; a text label is shown when count > 4.
-
-### Highlighting
-
-Field CSS classes are computed reactively inside the `view!` macro closure:
-
-| Class | Meaning |
-|-------|---------|
-| `.clickable` | Valid origin during Move stage (lime green) |
-| `.selected` | Currently selected origin (darker green + outline) |
-| `.dest` | Valid destination for the selected origin |
-
-`valid_sequences` (from `MoveRules`) is computed once per render and used to derive `valid_origins_for()` and `valid_dests_for()`. The displayed checker count (`displayed_value()`) accounts for staged-but-not-yet-sent moves so the board previews the move visually.
-
-### SVG arrow overlay
-
-When the player hovers a row in the ScoringPanel, the corresponding checker moves are drawn as gold arrows over the board. `field_center()` maps field numbers to pixel coordinates; `arrow_svg()` renders the path with a drop-shadow.
-
----
-
-## Scoring Display (`scoring.rs`, `score_panel.rs`)
-
-`compute_scored_event()` in `app.rs` diffs consecutive `ViewState` snapshots to produce a `ScoredEvent`:
-- `points_earned: i32`
-- `holes_gained: u8`
-- `jans: Vec<JanEntry>` — only events relevant to the beneficiary
-
-`ScoringPanel` renders one `JanEntry` per row. Hovering a row writes that entry's moves into `hovered_jan_moves`, triggering the arrow overlay on the board.
-
-`PlayerScorePanel` shows a colour-filled bar (animated via CSS `transition: width 0.3s`) for points (0–12) and holes (0–12). Bredouille state is shown with a small indicator.
-
----
-
-## Internationalisation
-
-`leptos_i18n::load_locales!()` is a compile-time macro that reads `locales/en.json` and `locales/fr.json` and generates a typed `i18n` module. There are 52 keys covering UI labels, game-state prompts, jan names, and status messages.
-
-Usage in components:
-```rust
-let i18n = use_i18n();
-t!(i18n, your_turn_roll)                       // → reactive View
-t_string!(i18n, scored_pts, pts = 4)           // → String with interpolation
-```
-
-The language switcher (top bar and login screen) calls `i18n.set_locale(Locale::en | Locale::fr)`, which triggers a full reactive re-render.
-
----
-
-## Styling
-
-`assets/style.css` is a single hand-written stylesheet (~472 lines). No CSS framework.
-
-Key design tokens:
-- Body background: `#c8b084` (tan)
-- Board background: `#2e6b2e` (dark green)
-- Fields: `#d4a843` / `#c49030` (gold alternating)
-- Interactive fields: `#aad060` (lime, clickable) / `#709a20` (darker, selected)
-- UI panels: `#f5edd8` (cream)
-
-Layout uses Flexbox and CSS Grid throughout. Score bars animate with `transition: width 0.3s`. Field clicks give immediate feedback via `transition: background 0.1s`. No media queries — the layout is designed for desktop/tablet.
-
----
-
-## Protocol Types (`types.rs`)
-
-| Type | Role |
-|------|------|
-| `PlayerAction` | `Roll \| Move(CheckerMove, CheckerMove) \| Go \| Mark` — UI → backend |
-| `GameDelta` | `{ state: ViewState }` — broadcast to all clients on every change |
-| `ViewState` | Full serialisable snapshot of engine state |
-| `JanEntry` | One scoring event: jan type, points, ways, moves, is_double |
-| `ScoredEvent` | Points/holes delta + jan list for one player in one turn |
-| `PlayerScore` | name, points (0–11), holes (0–12), can_bredouille |
-| `SerStage` | `PreGame \| InGame \| Ended` |
-| `SerTurnStage` | `RollDice \| RollWaiting \| MarkPoints \| HoldOrGoChoice \| Move \| MarkAdvPoints` |
-
-`CheckerMove` comes directly from `trictrac-store`; fields are 1-indexed (0 = stack/exit).

-## Build
-
-```bash
-trunk serve          # dev server at http://localhost:9092
-trunk build --release  # WASM release bundle
-```
-
-`index.html` uses Trunk's `data-trunk` attributes: `rel="rust"` compiles `src/main.rs` to WASM; `rel="css"` copies `assets/style.css`. The WASM binary and generated JS glue land in `dist/`.

+# Trictrac — Research Notes: Engine & OpenSpiel Integration
+
+> Generated from a deep read of `trictrac/store/src/` and `forks/open_spiel/open_spiel/python/games/trictrac.py`.
+
+---
+
+## 1. Architecture Overview
+
+The project connects two codebases through a compiled Python extension:
+
+```
+┌─────────────────────────────────────┐
+│  trictrac/store/  (Rust crate)      │
+│  - full game rules engine           │
+│  - pyengine.rs → PyO3 bindings      │
+│  compiled by maturin → .whl         │
+└──────────────┬──────────────────────┘
+               │  import trictrac_store
+┌──────────────▼──────────────────────┐
+│  forks/open_spiel/.../trictrac.py   │
+│  - TrictracGame  (pyspiel.Game)     │
+│  - TrictracState (pyspiel.State)    │
+│  registered as "python_trictrac"    │
+└─────────────────────────────────────┘
+```
+
+Build pipeline:
+- `just pythonlib` (in `trictrac/`) → `maturin build -m store/Cargo.toml --release` → `.whl` into `target/wheels/`
+- `just installtrictrac` (in `forks/open_spiel/`) → `pip install --force-reinstall` the wheel into the devenv venv
+
+The Rust crate is named `trictrac-store` (package) but produces a lib named `trictrac_store` (the Python module name, set in `Cargo.toml` `[lib] name`).
+
+---
+
+## 2. Rust Engine: Module Map
+
+| Module | Responsibility |
+|---|---|
+| `board.rs` | Board representation, checker manipulation, quarter analysis |
+| `dice.rs` | `Dice` struct, `DiceRoller`, bit encoding |
+| `player.rs` | `Player` struct (score, bredouille), `Color`, `PlayerId`, `CurrentPlayer` |
+| `game.rs` | `GameState` state machine, `GameEvent` enum, `Stage`/`TurnStage` |
+| `game_rules_moves.rs` | `MoveRules`: move validation and generation |
+| `game_rules_points.rs` | `PointsRules`: jan detection and scoring |
+| `training_common.rs` | `TrictracAction` enum, action-space encoding (size 514) |
+| `pyengine.rs` | PyO3 Python module exposing `TricTrac` class |
+| `lib.rs` | Crate root, re-exports |
+
+---
+
+## 3. Board Representation
+
+```rust
+pub struct Board {
+    positions: [i8; 24],
+}
+```
+
+- 24 fields indexed 0–23 internally, 1–24 externally.
+- Positive values = White checkers on that field; negative = Black.
+- Initial state: `[15, 0, ..., 0, -15]` — all 15 white pieces on field 1, all 15 black pieces on field 24.
+- Field 0 is a sentinel for "exited the board" (never stored in the array).
+
+**Mirroring** is the central symmetry operation used throughout:
+
+```rust
+pub fn mirror(&self) -> Self {
+    let mut positions = self.positions.map(|c| 0 - c);
+    positions.reverse();
+    Board { positions }
+}
+```
+
+This negates all values (swapping who owns each checker) and reverses the array (swapping directions). The entire engine always reasons from White's perspective; Black's moves are handled by mirroring the board first.
+
+**Quarter structure**: fields 1–6, 7–12, 13–18, 19–24. This maps to the four tables of Trictrac:
+- 1–6: White's "petit jan" (own table)
+- 7–12: White's "grand jan"
+- 13–18: Black's "grand jan" (= White's opponent territory)
+- 19–24: Black's "petit jan" / White's "jan de retour"
+
+The "coin de repos" (rest corner) is field 12 for White, field 13 for Black.
+
+---
+
+## 4. Dice
+
+```rust
+pub struct Dice {
+    pub values: (u8, u8),
+}
+```
+
+Dice are always a pair (never quadrupled for doubles, unlike Backgammon). The `DiceRoller` uses `StdRng` seeded from OS entropy (or an optional fixed seed for tests). Bit encoding: `"{d1:0>3b}{d2:0>3b}"` — 3 bits each, 6 bits total.
+
+---
+
+## 5. Player State
+
+```rust
+pub struct Player {
+    pub name: String,
+    pub color: Color,       // White or Black
+    pub points: u8,         // 0–11 (points within current hole)
+    pub holes: u8,          // holes won (game ends at >12)
+    pub can_bredouille: bool,
+    pub can_big_bredouille: bool,
+    pub dice_roll_count: u8, // rolls since last new_pick_up()
+}
+```
+
+`PlayerId` is a `u64` alias. Player 1 = White, Player 2 = Black (set at init time; this is fixed for the session in pyengine).
+
+---
+
+## 6. Game State Machine
+
+### Stages
+
+```rust
+pub enum Stage { PreGame, InGame, Ended }
+
+pub enum TurnStage {
+    RollDice,       // 1 — player must request a roll
+    RollWaiting,    // 0 — waiting for dice result from outside
+    MarkPoints,     // 2 — points are being marked (schools mode only)
+    HoldOrGoChoice, // 3 — player won a hole; choose to Go or Hold
+    Move,           // 4 — player must move checkers
+    MarkAdvPoints,  // 5 — mark opponent's points after the move (schools mode)
+}
+```
+
+### Turn lifecycle (schools disabled — the default in pyengine)
+
+```
+RollWaiting
+    │ RollResult → auto-mark points
+    ├─[no hole]──→ Move
+    │                │ Move → mark opponent's points → switch player
+    │                └───────────────────────────────→ RollDice (next player)
+    └─[hole won]─→ HoldOrGoChoice
+                    ├─ Go  ──→ new_pick_up() → RollDice (same player)
+                    └─ Move ──→ mark opponent's points → switch player → RollDice
+```
+
+In schools mode (`schools_enabled = true`), the player explicitly marks their own points (`Mark` event) and then the opponent's points after moving (`MarkAdvPoints` stage).
+
+### Key events
+
+```rust
+pub enum GameEvent {
+    BeginGame { goes_first: PlayerId },
+    EndGame { reason: EndGameReason },
+    PlayerJoined { player_id, name },
+    PlayerDisconnected { player_id },
+    Roll { player_id },         // triggers RollWaiting
+    RollResult { player_id, dice }, // provides dice values
+    Mark { player_id, points }, // explicit point marking (schools mode)
+    Go { player_id },           // choose to restart position after hole
+    Move { player_id, moves: (CheckerMove, CheckerMove) },
+    PlayError,
+}
+```
+
+### Initialization in pyengine
+
+```rust
+fn new() -> Self {
+    let mut game_state = GameState::new(false); // schools_enabled = false
+    game_state.init_player("player1");
+    game_state.init_player("player2");
+    game_state.consume(&GameEvent::BeginGame { goes_first: 1 });
+    TricTrac { game_state }
+}
+```
+
+Player 1 (White) always goes first. `active_player_id` uses 1-based indexing; pyengine converts to 0-based for the Python side with `active_player_id - 1`.
+
+---
+
+## 7. Scoring System (Jans)
+
+Points are awarded after each dice roll based on "jans" (scoring events) detected by `PointsRules`. All computation assumes White's perspective (board is mirrored for Black before calling).
+
+### Jan types
+
+| Jan | Points (normal / doublet) | Direction |
+|---|---|---|
+| `TrueHitSmallJan` | 4 / 6 | → active player |
+| `TrueHitBigJan` | 2 / 4 | → active player |
+| `TrueHitOpponentCorner` | 4 / 6 | → active player |
+| `FilledQuarter` | 4 / 6 | → active player |
+| `FirstPlayerToExit` | 4 / 6 | → active player |
+| `SixTables` | 4 / 6 | → active player |
+| `TwoTables` | 4 / 6 | → active player |
+| `Mezeas` | 4 / 6 | → active player |
+| `FalseHitSmallJan` | −4 / −6 | → opponent |
+| `FalseHitBigJan` | −2 / −4 | → opponent |
+| `ContreTwoTables` | −4 / −6 | → opponent |
+| `ContreMezeas` | −4 / −6 | → opponent |
+| `HelplessMan` | −2 / −4 | → opponent |
+
+A single roll can trigger multiple jans, each scored independently. The jan detection process:
+1. Try both dice orderings
+2. Detect "tout d'une" (combined dice move as a virtual single die)
+3. Prefer true hits over false hits for the same move
+4. Check quarter-filling opportunities
+5. Check rare jans (SixTables at roll 3, TwoTables, Mezeas) given specific board positions and talon counts
+
+### Hole scoring
+
+```rust
+fn mark_points(&mut self, player_id: PlayerId, points: u8) -> bool {
+    let sum_points = p.points + points;
+    let jeux = sum_points / 12;          // number of completed holes
+    let holes = match (jeux, p.can_bredouille) {
+        (0, _) => 0,
+        (_, false) => 2 * jeux - 1,     // no bredouille bonus
+        (_, true)  => 2 * jeux,          // bredouille doubles the holes
+    };
+    p.points = sum_points % 12;
+    p.holes += holes;
+    ...
+}
+```
+
+- 12 points = 1 "jeu", which yields 1 or 2 holes depending on bredouille status.
+- Scoring any points clears the opponent's `can_bredouille`.
+- Completing a hole resets `can_bredouille` for the scorer.
+- Game ends when `holes > 12`.
+- Score reported to OpenSpiel: `holes * 12 + points`.
+
+### Points from both rolls
+
+After a roll, the active player's points (`dice_points.0`) are auto-marked immediately. After the Move, the opponent's points (`dice_points.1`) are marked (they were computed at roll-time from the pre-move board).
+
+---
+
+## 8. Move Rules
+
+`MoveRules` always works from White's perspective. Key constraints enforced by `moves_allowed()`:
+
+1. **Opponent's corner forbidden**: Cannot land on field 13 (opponent's rest corner for White).
+2. **Corner needs two checkers**: The rest corner (field 12) must be taken or vacated with exactly 2 checkers simultaneously.
+3. **Corner by effect vs. by power**: If the corner can be taken directly ("par effet"), you cannot take it "par puissance" (using combined dice).
+4. **Exit preconditions**: All checkers must be in fields 19–24 before any exit is allowed.
+5. **Exit by effect priority**: If a normal exit is possible, exceedant moves (using overflow) are forbidden.
+6. **Farthest checker first**: When exiting with exceedant, must exit the checker at the highest field.
+7. **Must play all dice**: If both dice can be played, playing only one is invalid.
+8. **Must play strongest die**: If only one die can be played, it must be the higher value die.
+9. **Must fill quarter**: If a quarter can be completed, the move must complete it.
+10. **Cannot block opponent's fillable quarter**: Cannot move into a quarter the opponent can still fill.
+
+The board state after each die application is simulated to check two-step sequences.
+
+---
+
+## 9. Action Space (training_common.rs)
+
+Total size: **514 actions**.
+
+| Index | Action | Description |
+|---|---|---|
+| 0 | `Roll` | Request dice roll (not used in OpenSpiel mode) |
+| 1 | `Go` | After winning hole: reset board and continue |
+| 2–257 | `Move { dice_order: true, checker1, checker2 }` | Move with die[0] first |
+| 258–513 | `Move { dice_order: false, checker1, checker2 }` | Move with die[1] first |
+
+Move encoding: `index = 2 + (0 if dice_order else 256) + checker1 * 16 + checker2`
+
+`checker1` and `checker2` are **ordinal positions** (1-based) of specific checkers counted left-to-right across all White-occupied fields, not field indices. Checker 0 = "no move" (empty move). Range: 0–15 (16 values each).
+
+### Mirror pattern in get_legal_actions / apply_action
+
+For player 2 (Black):
+```rust
+// get_legal_actions: mirror game state before computing
+let mirror = self.game_state.mirror();
+get_valid_action_indices(&mirror)
+
+// apply_action: convert action → event on mirrored state, then mirror the event back
+a.to_event(&self.game_state.mirror())
+ .map(|e| e.get_mirror(false))
+```
+
+This ensures Black's actions are computed as if Black were White on a mirrored board, then translated back to real-board coordinates.
+
+---
+
+## 10. Python Bindings (pyengine.rs)
+
+The `TricTrac` PyO3 class exposes:
+
+| Method | Signature | Description |
+|---|---|---|
+| `new()` | `→ TricTrac` | Create game, init 2 players, begin with player 1 |
+| `needs_roll()` | `→ bool` | True when in `RollWaiting` stage |
+| `is_game_ended()` | `→ bool` | True when `Stage::Ended` |
+| `current_player_idx()` | `→ u64` | 0 or 1 (active_player_id − 1) |
+| `get_legal_actions(player_idx)` | `→ Vec<usize>` | Action indices for player; empty if not their turn |
+| `action_to_string(player_idx, action_idx)` | `→ String` | Human-readable action description |
+| `apply_dice_roll(dices: (u8, u8))` | `→ PyResult<()>` | Inject dice result; errors if not in RollWaiting |
+| `apply_action(action_idx)` | `→ PyResult<()>` | Apply a game action; validates before applying |
+| `get_score(player_id)` | `→ i32` | `holes * 12 + points` for player (1-indexed!) |
+| `get_players_scores()` | `→ [i32; 2]` | `[score_p1, score_p2]` |
+| `get_tensor(player_idx)` | `→ Vec<i8>` | 36-element state vector (mirrored for player 1) |
+| `get_observation_string(player_idx)` | `→ String` | Human-readable state (mirrored for player 1) |
+| `__str__()` | `→ String` | Debug representation of game state |
+
+Note: `get_score(player_id)` takes a 1-based player ID (1 or 2), unlike `current_player_idx()` which returns 0-based.
+
+---
+
+## 11. State Tensor Encoding (36 bytes)
+
+```
+[0..23]  Board positions (i8): +N white / −N black checkers per field
+[24]     Active player: 0=White, 1=Black
+[25]     TurnStage: 0=RollWaiting, 1=RollDice, 2=MarkPoints, 3=HoldOrGoChoice,
+                   4=Move, 5=MarkAdvPoints
+[26]     Dice value 1 (i8)
+[27]     Dice value 2 (i8)
+[28]     White: points (0–11)
+[29]     White: holes (0–12)
+[30]     White: can_bredouille (0 or 1)
+[31]     White: can_big_bredouille (0 or 1)
+[32]     Black: points
+[33]     Black: holes
+[34]     Black: can_bredouille
+[35]     Black: can_big_bredouille
+```
+
+When called for player 1 (Black), the entire state is mirrored first (`game_state.mirror().to_vec()`).
+
+### State ID (base64 string for hashing)
+
+108 bits packed as 18 base64 characters:
+- 77 bits: GNUbg-inspired board position encoding (run-length with separators)
+- 1 bit: active player color
+- 3 bits: turn stage
+- 6 bits: dice (3 bits per die)
+- 10 bits: white player (4 pts + 4 holes + 2 flags)
+- 10 bits: black player
+- Padded to 108 bits, grouped as 18 × 6-bit base64 chunks
+
+---
+
+## 12. OpenSpiel Integration (trictrac.py)
+
+### Game registration
+
+```python
+pyspiel.register_game(_GAME_TYPE, TrictracGame)
+```
+
+Key parameters:
+- `short_name = "python_trictrac"`
+- `dynamics = SEQUENTIAL`
+- `chance_mode = EXPLICIT_STOCHASTIC`
+- `information = PERFECT_INFORMATION`
+- `utility = GENERAL_SUM` (both players can score positive; no zero-sum constraint)
+- `reward_model = REWARDS` (intermediate rewards, not just terminal)
+- `num_distinct_actions = 514`
+- `max_chance_outcomes = 36`
+- `min_utility = 0.0`, `max_utility = 200.0`
+- `max_game_length = 3000` (rough estimate)
+
+### Chance node handling
+
+When `needs_roll()` is true, the state is a chance node. OpenSpiel samples one of 36 outcomes (uniform):
+
+```python
+def _roll_from_chance_idx(self, action):
+    return [(i,j) for i in range(1,7) for j in range(1,7)][action]
+
+def chance_outcomes(self):
+    p = 1.0 / 36
+    return [(i, p) for i in range(0, 36)]
+```
+
+Action 0 → (1,1), action 1 → (1,2), …, action 35 → (6,6). The chance action is then passed to `apply_dice_roll((d1, d2))` on the Rust side.
+
+### Player action handling
+
+When not a chance node:
+```python
+def _legal_actions(self, player):
+    return self._store.get_legal_actions(player)
+
+def _apply_action(self, action):
+    self._store.apply_action(action)
+```
+
+The `Roll` action (index 0) is never returned by `get_legal_actions` in this mode because the Rust side only returns Roll actions from `TurnStage::RollDice`, which is bypassed in the pyengine flow (the RollWaiting→chance node path takes over).
+
+### Returns
+
+```python
+def returns(self):
+    return self._store.get_players_scores()
+# → [holes_p1 * 12 + points_p1, holes_p2 * 12 + points_p2]
+```
+
+These are cumulative scores available at any point during the game (not just terminal), consistent with `reward_model = REWARDS`.
+
+---
+
+## 13. Known Issues and Inconsistencies
+
+### 13.1 `observation_string` missing return (trictrac.py:156)
+
+```python
+def observation_string(self, player):
+    self._store.get_observation_string(player)  # result discarded, returns None
+```
+
+Should be `return self._store.get_observation_string(player)`.
+
+### 13.2 `observation_tensor` not populating buffer (trictrac.py:159)
+
+```python
+def observation_tensor(self, player, values):
+    self._store.get_tensor(player)  # result discarded, values not filled
+```
+
+OpenSpiel's API expects `values` (a mutable buffer, typically a flat numpy array) to be filled in-place. The returned `Vec<i8>` from `get_tensor()` is discarded. Should copy data into `values`.
+
+### 13.3 Debug print statement active (trictrac.py:140)
+
+```python
+print("in apply action", self.is_chance_node(), action)
+```
+
+This fires on every action application. Should be removed or guarded.
+
+### 13.4 Color swap on new_pick_up disabled
+
+In `game.rs:new_pick_up()`:
+
+```rust
+// XXX : switch colors
+// désactivé pour le moment car la vérification des mouvements échoue,
+// cf. https://code.rhumbs.fr/henri/trictrac/issues/31
+// p.color = p.color.opponent_color();
+```
+
+In authentic Trictrac, players swap colors between "relevés" (pick-ups after a hole is won with Go). This is commented out, so the same player always plays White and the same always plays Black throughout the entire game.
+
+### 13.5 `can_big_bredouille` tracked but not implemented
+
+The `can_big_bredouille` flag is stored in `Player` and serialized in state encoding, but the scoring logic never reads it. Grande bredouille (a rare extra bonus) is not implemented.
+
+### 13.6 `Roll` action in action space but unused in OpenSpiel mode
+
+`TrictracAction::Roll` (index 0) exists in the 514-action space and in `get_valid_actions()` (for `TurnStage::RollDice`). However, in pyengine, the game starts at `RollWaiting` (dice have been requested but not yet rolled), so `TurnStage::RollDice` is never reached from OpenSpiel's perspective. The chance node mechanism replaces the Roll action entirely. The action space slot 0 is permanently wasted from OpenSpiel's point of view.
+
+### 13.7 `get_valid_actions` panics on `RollWaiting`
+
+```rust
+TurnStage::MarkPoints | TurnStage::MarkAdvPoints | TurnStage::RollWaiting => {
+    panic!("get_valid_actions not implemented for turn stage {:?}", ...)
+}
+```
+
+If `get_legal_actions` were ever called while `needs_roll()` is true, this would panic. OpenSpiel's turn logic avoids this because chance nodes are handled separately, but it is a latent danger.
+
+### 13.8 PPO training script uses wrong model name
+
+`trictrac_ppo.py` saves to `ppo_backgammon_model.ckpt` — clearly copied from a backgammon example without renaming. Also uses `tensorflow.compat.v1` despite the PyTorch PPO import.
+
+### 13.9 Opponent points marked at pre-move board state
+
+The opponent's `dice_points.1` is computed at roll time (before the active player moves), but applied to the opponent after the move. This means the opponent's scoring is evaluated on the board position that existed before the active player moved — which is per the rules of Trictrac (points are based on where pieces could be hit at the moment of the roll), but it's worth noting this subtlety.
+
+---
+
+## 14. Data Flow: A Complete Turn
+
+```
+Python (OpenSpiel)          →  Rust (trictrac_store)
+─────────────────────────────────────────────────────
+is_chance_node()            ←  needs_roll() [TurnStage == RollWaiting]
+                                (true at game start)
+
+chance_outcomes() → [(0,p)..(35,p)]
+
+_apply_action(chance_idx)
+  _roll_from_chance_idx(idx) → (d1, d2)
+  apply_dice_roll((d1, d2))  →  consume(RollResult{dice})
+                                  → auto-mark active player's points
+                                  → if hole: TurnStage=HoldOrGoChoice
+                                  → else: TurnStage=Move
+
+current_player() → 0 or 1
+
+_legal_actions(player)      ←  get_legal_actions(player_idx)
+                                  → get_valid_actions on (possibly mirrored) state
+                                  → Vec<usize> of valid action indices
+
+_apply_action(action_idx)   →  apply_action(action_idx)
+                                  → TrictracAction::from_action_index
+                                  → to_event on (mirrored) state
+                                  → mirror event back if player==2
+                                  → validate → consume
+                                  → mark opponent points
+                                  → switch active player
+                                  → TurnStage=RollDice (→ pyengine starts next turn)
+
+Wait — pyengine starts at RollWaiting, not RollDice!
+The next is_chance_node() call will be true again.
+```
+
+Note on turn transition: After a `Move` event in `game.rs`, turn stage becomes `RollDice` (not `RollWaiting`). The pyengine `needs_roll()` checks for `RollWaiting`. So after a move, `is_chance_node()` returns false — OpenSpiel will ask for a regular player action. But `get_valid_actions` at `TurnStage::RollDice` returns only `Roll` (index 0), which is **not** the chance path.
+
+This reveals a subtlety: after the Move event, the active player has already been switched, so `current_player()` returns the new active player, and `get_legal_actions` returns `[0]` (Roll). OpenSpiel then applies action 0, which calls `apply_action(0)` → `TrictracAction::Roll` → `GameEvent::Roll` → TurnStage becomes `RollWaiting`. Then the next call to `is_chance_node()` returns true, and the chance mechanism kicks in again.
+
+So the full sequence in OpenSpiel terms is:
+```
+[Chance] dice roll → [Player] move → [Player] Roll action → [Chance] dice roll → ...
+```
+
+The `Roll` action IS used — it is the bridge between Move completion and the next chance node.
+

+
+## 15. Summary of Design Choices
+
+| Choice | Rationale |
+|---|---|
+| All rules engine in Rust | Performance, correctness, can be used in other contexts (CLI, native bots) |
+| Mirror pattern for Black | Avoids duplicating all rule logic for both colors |
+| Schools disabled by default | Simpler turn structure for RL training; full protocol for human play |
+| GENERAL_SUM + REWARDS | Trictrac is not strictly zero-sum; intermediate hole rewards are informative for training |
+| Action index for checkers (not fields) | Reduces action space; ordinal checker numbering is compact |
+| 514 action slots | 1 Roll + 1 Go + 256 × 2 move combinations (ordered by die priority × 16 × 16 checker pairs) |
+| Chance node = dice roll | Standard OpenSpiel pattern for stochastic games |

-# LAWS AND RULES OF TRICTRAC
-
-2013 EDITION — SUPPLEMENT TO THE REASONED DICTIONARY OF THE GAME OF TRICTRAC www.trictrac.org by Michel MALFILÂTRE (trictrac.org)
-
-_Translator's note: French game terms are preserved in italics on first use. See [vocabulary.md](vocabulary.md) for a complete French/English mapping._
-
-There are two types of game in grand trictrac: the ordinary game and the scored game.
-In both, the main laws and rules are the same; but the goal, scoring, and payments differ.
-
-## ARTICLE I: THE ORDINARY GAME
-
-It is played between two players; the goal is to be the first to score 12 holes (_trous_). One hole equals 12 points.
-
-## ARTICLE II: THE SCORED GAME
-
-It can be played by 2, 3, or 4 players in teams or in _chouette_ format. The goal is to win as many tokens as possible by playing an agreed number of rounds (_marqués_). A round always pits two players against each other. With three or four players, participants rotate at each round in a defined order.
-
-To win a round, a player must score at least 6 holes and then leave (_s'en aller_) (see Article XV). The maximum number of holes per round is generally unlimited, but players may agree otherwise.
-
-If both players are tied at or above 6 holes when one player leaves, the round is drawn and must be replayed (_refait_) immediately.
-
-## ARTICLE III: EQUIPMENT
-
-The game is played on a board called a _trictrac_, composed of two tables: the small jan table and the big jan table. The first table contains each player's small jan and the second contains each player's big jan. One player's small jan is also the other player's return jan. Each jan consists of 6 alternately coloured fields (_flèches_).
-
-The board has 24 triangular fields in total and 30 holes drilled into its rails and bands.
-
-A hole is drilled at the base of each field. These holes hold each player's peg (_fichet_) to record the holes (games) won. The three holes on each side rail serve to place pegs at the start of the game, along with the flag (_pavillon_).
-
-In addition to these three pegs (one of which is the flag), the game uses 30 checkers — 15 white and 15 black (or two other contrasting colours) — three tokens (_jetons_), two dice cups (_cornets_), and two six-sided dice.
-
-The scored game is also played with tokens used for payments, or with paper and pencil to keep a token account.
-
-## ARTICLE IV: STARTING POSITION
-
-At the start of the game, all checkers are stacked into two separate stacks (_talons_): one of white checkers, one of black. Each stack is placed facing the other on a corner field adjacent to one of the two outer side rails, called the starting rail. This rail may later become the exit rail.
-
-Each player uses the checkers from the stack closest to them. The corner fields against the other outer side rail are the rest corners. The twelfth field of each player — counting the stack as the first — is therefore that player's rest corner, or simply: _corner_.
-
-Pegs are placed in the 3 holes of the starting rail, with the flag occupying the central hole. Three tokens are placed against this rail between the two stacks.
-
-## ARTICLE V: FIRST-MOVE PRIVILEGE
-
-To determine who plays first at the start of a game, each player rolls a die with a dice cup; the player who rolls the higher number generally takes the white checkers and begins, playing both numbers rolled.
-
-An alternative method: one player rolls both dice; the player closest to the higher die plays first, playing both numbers rolled.
-
-In both cases, if the dice show the same value, they must be re-rolled. A game may therefore not begin with a double.
-
-After each new setting (_relevé_), first-move privilege belongs to the player who first exited all their checkers or who left first (see Articles VIII and XV).
-
-In the scored game with two players, first-move privilege alternates each round. With three or four players, it belongs to the player who remains to face a new opponent.
-
-In case of a replay, the player who had first-move privilege in the drawn round retains it for that replay and any subsequent replays.
-
-## ARTICLE VI: ROLLING AND PLAYING THE DICE
-
-Both dice must be rolled together with a dice cup. They are valid when they land flat inside the board, even if resting on a checker or token. If a die is broken, rests on a rail, or lands outside the board, both dice must be re-rolled.
-
-The two numbers may be played with two checkers — each playing one number — or with a single checker playing both numbers successively in a chained move (_tout d'une_) (for 6 and 1: the 6 advances a checker six fields and the 1 advances another one field; or a single checker moves seven fields total, stopping on the first or sixth field as a resting point before reaching the seventh).
-
-Both numbers must be played if possible. If only one can be played and there is a choice, the higher number must be played.
-
-Any unplayed number is penalised: this is a _jan-qui-ne-peut_ (helpless man), worth 2 helplessness points per unplayed number, credited to the opponent.
-
-Dice must not be picked up before the move is fully played and all points marked (including school penalties).
-
-## ARTICLE VII: MOVEMENT OF CHECKERS
-
-Checkers always move in the same direction — opposite to the opponent's — and never backwards.
-
-In the course of a game, checkers travel from the stack to the rest corner (the twelfth field), then back to the opponent's stack on the return.
-
-A checker may only be placed, or made to rest during a chained move, on an empty field or one already occupied by one or more of the player's own checkers. The rest corner is an exception to this rule (see Article IX).
-
-A checker may not be placed on a field occupied by the opponent's checker(s).
-
-## ARTICLE VIII: EXITING CHECKERS
-
-When all of a player's checkers are gathered in their last jan (return jan), they are exited from the board using the exit rail privilege, which grants this rail the value of one additional field.
-
-A checker may be exited by an exact exit number that brings it directly to the exit rail, or by an overflow number (_nombre excédant_) that would carry the farthest checker beyond the rail. Other numbers — failing numbers (_nombres défaillants_) — must be played within the jan.
-
-A checker may be exited in a chained move. A player may choose not to exit a checker on an exact exit number and instead play another checker within the jan as a failing number, if possible; but an overflow number must always exit a checker.
-
-When exiting, all non-exiting numbers must be played within the jan when possible. It is therefore not permitted to play one number in a way that forces the second to be played only as an overflow. Likewise, if a number cannot be played within the jan due to the presence of opponent checkers, it may not be played as an overflow using a checker closer to the exit rail.
-
-When a player has exited all their checkers, they score 4 points for the last exited checker on a normal roll, or 6 points on a double.
-
-The checkers of both players are then reset and returned to their respective stacks; play continues with no change to the score. By privilege, the player who exited first rolls again and plays (first-move privilege).
-
-Exiting can occur multiple times in a game.
-
-## ARTICLE IX: THE REST CORNER
-
-The rest corner may only be taken simultaneously (_d'emblée_): two checkers must enter it at the same time. Likewise, it may only be vacated simultaneously. It must therefore always be occupied by at least two checkers. It is forbidden to place or leave a single checker on one's own rest corner.
-
-Under any circumstances, it is forbidden to place one or more checkers on the opponent's rest corner.
-
-An empty corner may, however, serve as a resting field for any checker during a chained move.
-
-A player may take their corner by effect (_par effet_, naturally), or by puissance (_par puissance_) — the latter when the opponent's corner is empty and the player could take it simultaneously. By privilege, the player takes their own corner instead, as if stepping back one field.
-
-If a player can take their corner both by effect and by puissance, they must take it by effect.
-
-After vacating the corner, it may be retaken under the same conditions.
-
-## ARTICLE X: HITTING CHECKERS
-
-This _jan de récompense_ (reward jan) occurs when an opponent's checker is exposed alone on a half-field and the player rolls numbers that could cover it with one or more of their own checkers.
-
-The hit is always fictitious — it exists only as a potential; no checker is actually moved.
-
-A checker may be hit in one, two, or three ways:
-
-- **One way**: only one of the direct die values, or the combined sum, could cover the checker.
-- **Two ways**: both direct die values could cover it, or one direct value and the combined sum.
-- **Three ways**: both direct values can cover it, and the combined sum can as well.
-
-By its nature, a double allows at most one or two ways to hit:
-
-- **One way**: one direct value, or the combined sum.
-- **Two ways**: one direct value and the combined sum.
-
-Only one way is counted on a double, even when two checkers on a field could each cover the opponent's checker.
-
-Multiple checkers may be hit in the same move.
-
-For each checker hit and for each way it is hit, this reward jan is worth:
-
-- **2 points** on a normal roll, **4 points** on a double — if the hit checker is in the big jan table.
-- **4 points** on a normal roll, **6 points** on a double — if the hit checker is in the small jan table or return jan.
-
-Reward jans must be marked by the player who achieves them (under penalty of being "sent to school" — see Article XVI).
-
-To hit a checker using the combined sum, the player must have a resting field (_repos_): a field where one die can land so that the second can (fictitiously) reach the target checker. This resting field must be either empty, already held by the player's own checkers, or occupied by a single opponent checker — which is then also hit.
-
-A _helpless man_ (_jan-qui-ne-peut_) occurs when, attempting to hit using the combined sum, no free resting field exists and the player must stop on a full field held by the opponent. The hit is then a **false hit** (_à faux_), and the opponent gains as many points as the player would have scored with a true hit.
-
-A checker already hit with a true hit cannot also be hit with a false hit in the same move. However, multiple checkers may be hit simultaneously — some truly, others falsely.
-
-Points for true hits must be marked before those given to the opponent for false hits. The opponent must mark their false-hit points in due time, under penalty of school (see Article XVI).
-
-## ARTICLE XI: HITTING THE CORNER
-
-This reward jan occurs when a player holds their own rest corner, the opponent's corner is empty, and the player rolls numbers that would let them take the opponent's corner simultaneously, without unstacking their own corner (i.e., without using the two checkers already holding it).
-
-Since taking the opponent's corner is actually forbidden, the player hits it instead, scoring **4 points** on a normal roll and **6 points** on a double. This hit can never be false, as it uses two direct die values and never the combined sum.
-
-## ARTICLE XII: OPENING JANS
-
-There are three opening jans: the **two tables jan**, the **mezeas jan**, and the **six tables jan**. They can only be achieved at the start of a game, a round, or their respective new settings.
-
-### TWO TABLES JAN
-
-At the start of a game, round, or new setting — when only two checkers have been deployed — if the player rolls numbers that would place one checker on their own empty rest corner and one on the opponent's, a two tables jan is scored if the opponent's corner is also empty; otherwise, if the opponent has already taken their corner, a **contre two tables** is scored instead.
-
-In the first case, hitting both corners is worth **4 points** on a normal roll and **6 points** on a double, credited to the player. In the second case, the same point value is credited to the opponent as a false hit.
-
-### MEZEAS JAN
-
-At the start of a game, round, or new setting — having taken one's corner with only two checkers deployed — if on the very next roll one or two aces (1s) are rolled, a mezeas jan is scored if the opponent's corner is empty; otherwise, a **contre mezeas** is scored.
-
-In the first case, hitting the corner is worth **4 points** per ace and **6 points** for a double; in the second case, the same value is credited to the opponent.
-
-### SIX TABLES JAN (THREE-ROLL JAN)
-
-At the start of a game, round, or new setting — having placed one checker on four of the first six fields (fields 2–7) during the first two rolls — if on the third roll the player could fill the remaining two fields, they score a six tables jan. This jan is worth **4 points** in all cases, as it cannot be achieved with a double.
-
-The player is not obliged to actually fill those two fields; they are free to play the roll however they prefer.
-
-## ARTICLE XIII: SMALL JAN, BIG JAN & RETURN JAN
-
-### THE FULL JAN (PLEIN)
-
-A jan is full (_plein_) when a player occupies each of its six fields with at least two of their own checkers.
-
-Each player may fill their small jan, big jan, and return jan.
-
-A full jan may be broken and then refilled. Over the course of a game, a player may fill several different jans successively, or the same jan multiple times.
-
-### FILLING
-
-A jan is filled when the player rolls numbers that complete the full jan by bringing in the last checker.
-
-A jan may be filled in one, two, or three ways:
-
-- **One way**: the last half-field can be covered by one direct die value or by the combined sum in a chained move.
-- **Two ways**: it can be covered by either direct die value, or by one direct value and the combined sum.
-- **Three ways**: it can be covered by either direct value, and also by the combined sum.
-
-Each way of filling is worth **4 points** on a normal roll and **6 points** on a double.
-
-For a jan to be filled in multiple ways, exactly one checker must be missing — only the last checker brought in actually fills the jan. Therefore, a player fills in only one way when taking the last field simultaneously or covering both last half-fields in the same move.
-
-A double allows at most two ways to fill.
-
-A jan is not effectively filled when, though able to complete it with one die, the player must break it to play the other. When a player "fills in passing" this way, no points are scored and they are not obliged to perform the filling.
-
-The return jan may not be filled by counting either of the two checkers holding the rest corner as a way of filling — doing so would unstack the corner, which is forbidden.
-
-After marking points for filling a jan, the player must actually fill it with one or two checkers, under penalty of false move and school (see Article XVII).
-
-If the jan can be filled in multiple ways, the player fills it with the checker of their choice and is free to play the other die as they wish.
-
-### CONSERVING
-
-A full jan is conserved when the player can play both dice without breaking it — that is, without using any of the twelve checkers that compose the full jan.
-
-Conserving a full jan is worth **4 points** on a normal roll and **6 points** on a double. There can be at most one way to conserve.
-
-A player may use the privilege of conserving by helplessness (_par impuissance_) when, having a full jan, the position prevents playing one or both numbers. Only the number 6 allows this conservation, as all lower numbers can be played within the jan (even if it means breaking the full jan).
-
-By privilege, the full return jan may be conserved by exiting one, two, or three checkers.
-
-As with filling, when it is possible to play without breaking a full jan, the player must actually conserve it — under penalty of false move and school (see Article XVII).
-
-## ARTICLE XIV: FORBIDDEN JANS
-
-It is forbidden to place a checker in the opponent's small jan or big jan as long as the opponent retains the material possibility of filling that jan with the checkers available to them.
-
-This prohibition normally ends once the opponent has moved enough checkers beyond the fields needed to complete the jan, so that those checkers can no longer serve to fill it — making the full jan materially impossible.
-
-Once the opponent can no longer complete the full jan, the player has the right to place one or more of their own checkers there.
-
-However, when playing a chained move, it is always permitted to use the empty fields of the opponent's big jan (including the corner) as a resting field — even if it can still be filled — in order to pass a checker into the return jan, as long as the return jan is not itself forbidden.
-
-## ARTICLE XV: SCORING
-
-Points and holes won must always be marked before touching one's checkers to play, or before rolling the dice for the next move if those points come from the opponent's roll (helpless man, contre-jans, schools).
-
-Points are marked with tokens. For **2 points**, the token is placed at the tip of the player's second field or between the second and third fields; for **4 points**, at the fourth or between the fourth and fifth; for **6 points**, at the sixth or against the cross-rail; for **8 points**, on the other side of that rail, in the big jan; for **10 points**, against the side rail of the big jan or at the tip of the rest corner field. **12 or 0 points** are marked against the starting rail between the two stacks, as at the start of the game.
-
-12 points make a hole. If the 12 points of a hole were all scored consecutively from zero — that is, without the opponent having scored any points during that run — the hole is won _bredouille_ and counts as **2 holes**. This double-hole advantage applies equally to the first and second player to start marking. The first player to mark uses a single token and can win the hole bredouille as long as the opponent scores nothing. If the opponent then scores, they mark with a double token called the _bredouille_ and continue marking this way as long as the first player scores nothing. If they reach at least 12 points in this fashion, they win the hole bredouille in second. But if the first player scores again beforehand, they remove one of the opponent's two tokens (_débredouiller_), and neither player can thereafter win the hole bredouille. Once both players each have a single-token mark, the hole will necessarily be won simple by one or the other.
-
-Holes are marked with pegs. Each player advances their peg along the row of holes drilled at the base of the twelve fields in their small and big jans. The first hole is at the base of the stack, the twelfth and last at the base of the rest corner.
-
-Earned holes must be marked before touching the tokens. Any opponent token (bredouille or not) is then reset to zero at the starting rail. The player's own token is also reset if they scored exactly 12 points; otherwise the remainder — _points de reste_ — are marked normally with a token.
-
-If on the same move the opponent is owed points, they mark them afterwards, starting from zero, using one or two tokens depending on whether the player marked any remainder points.
-
-Multiple holes, both single and double, may be won in the same move.
-
-In the scored game, a round may be won simple, double, or quadruple depending on whether the holes were scored consecutively. If the holes were not consecutive, the round is simple. If at least 6 holes were consecutive, the round is won in small bredouille and counts double. If at least 12 holes were consecutive, it is won in big bredouille and counts quadruple.
-
-As with the hole bredouille, this advantage applies equally to the first and second player to score holes. The second player takes the flag and places it at their peg's starting position on the starting rail. If the first player wins new holes, they take the flag back and return it to the central hole. The round is then necessarily won simple.
-
-## ARTICLE XVI: STAYING OR LEAVING
-
-When a player wins one or more holes through their own dice roll, they may choose to stay (_tenir_) or use the privilege of leaving (_s'en aller_). If the winning points come from the opponent's roll (helpless man, schools), the player must stay.
-
-**Staying**: after marking the hole(s), the player resets the opponent's token if necessary, marks any remainder points, and continues playing normally. The opponent then marks any points they may have earned from this move (see Article XV).
-
-**Leaving**: after marking the hole(s), the player verbally announces their intention to leave, as the opponent may object in case of a fault or school. Once the opponent has verbally agreed or begun breaking their position, all tokens are reset to zero and all checkers of both players are returned to their stacks. Only the holes won remain. No remainder points may be marked and the opponent cannot mark points or holes for this move. Play resumes from the start; by privilege, the player who left has first-move privilege for this new setting — they roll and play.
-
-In the scored game, once a player has scored at least 6 holes, if either player leaves, the round ends. The winner is whoever has the most holes. In case of a tie, the round is drawn and replayed.
-
-## ARTICLE XVII: FAULTS AND SCHOOLS
-
-There are three types of fault in this game:
-
-**1. Simple faults** — of little harm to the opponent; some can be corrected normally (e.g., playing out of turn, rolling outside the board, accidentally disturbing the position, forgetting to mark a school). No penalty is incurred for these faults.
-
-**2. False move faults (_fausse case_)** — potentially harmful; occur when a checker is not played to the correct field given the numbers rolled, or when a rule of play is violated (laws regarding the rest corner, forbidden jans, filling, and conserving). A false move may give rise to a school when points have been marked for a jan that is not then actually performed — as the rules require (e.g., marking for filling or conserving but not doing so). In addition to the rule "checker touched, checker abandoned, checker played" (unless the player said "_j'adoube_"), the player must accept the opponent's decision regarding rectification of the fault.
-
-The opponent must point out the fault(s) before rolling for their own move; they may rectify the fault in their own interest, while respecting the rules, or leave the position unchanged. If a corner was taken by puissance when it could have been taken by effect, the opponent may prevent the player from taking it on that move if the fault is recognised and an alternative play exists. If a half-field was falsely covered, the opponent may also prevent the covering.
-
-**3. Marking faults** — always harmful; occur when points or holes are forgotten, over-marked, or marked incorrectly. The opponent may penalise the player by "sending them to school." A school is committed once dice have been rolled or checkers touched, or once a token marker has been advanced too far and released. In some cases the school is committed as soon as an intentional declaration is made (leaving, school, invitation to play).
-
-A school is worth to the opponent exactly as many points as were missed or over-marked in a move. Moreover, in case of over-marking, the opponent corrects the mark by removing the excess points. When marking school points, or just after, the opponent must announce it by saying: "School!" or "N points of school."
-
-No one is obliged to mark a school — there is no "school of school." But if it is marked, it must be marked in full, or the opponent may request rectification. The opponent may also force the faulty player to correct their mark without marking the school.
-
-A **false school** occurs when a player marks an incorrect school or a school that does not exist. This is itself a school that the opponent may mark in their favour.
-
-A **school escalation** occurs when a player who committed a school has had it marked by their opponent, believes the opponent erred, removes that school and marks it in their own favour as a false school — but the opponent, maintaining the school was valid, removes the player's mark, restores the first school, and adds further points for this second school. The dispute could continue indefinitely unless the players reach a frank resolution.
-
-At any time a player may ask their opponent to explain the points they are marking or removing. The opponent must explain.
-
-No school of holes is incurred for marking a hole won bredouille as a simple hole. But a school of points is incurred for holes forgotten due to points earned, or for holes over-marked for points not earned.
-
-School points are marked last.
-
-## ARTICLE XVIII: SEQUENCE OF PLAY
-
-For a move to be regular, each player must act in the following order:
-
-As soon as the opponent's move ends:
-
-1. If applicable, mark the opponent's helpless man penalties or contre-jans.
-2. If applicable and desired, mark the opponent's schools and announce: "School!"; rectify any false moves and marking errors.
-
-Then:
-
-3. Roll the dice for one's own move. If applicable, the opponent then marks any schools committed in steps 1 and 2. Resolve false schools and school escalations.
-4. If applicable, mark points for opening jans, reward jans (checker hits and corner hits), filled or conserved jans, or exit points.
-5. If applicable, decide to stay or leave:
-   - **Stay**: reset tokens and mark any remainder points.
-   - **Leave**: announce it, then break the position after the opponent's agreement. Reset all checkers, reset all tokens, and roll again to play (unless the game or round is over).
-6. In case of exit: reset checkers, do not reset either player's tokens, and roll again to play.
-7. Play both numbers rolled if possible.
-
-The opponent then plays following the same sequence.
-
-8. If applicable, mark any schools the opponent committed in their steps 1 and 2, as soon as they have rolled the dice, or interrupt the roll to rectify the marking.
-
-Failure to respect this sequence is a fault and may be penalised by the opponent.
-
-## ARTICLE XIX: THE SCORED GAME
-
-### THREE- AND FOUR-PLAYER GAME
-
-The number of rounds chosen for the game must be a multiple of the number of players, so that each player faces every opponent the same number of times.
-
-With three players, the first round pairing is drawn by lot. The player who draws the highest number begins with white checkers and plays the two numbers rolled.
-
-For the second round, the winner is replaced by the third player, but first-move privilege belongs to the player who stayed at the table.
-
-For the following round, the third player remains but the others alternate.
-
-Each player thus plays two rounds in a row against different opponents. Only the winner of the first round plays just once — at the very beginning and at the very end of the game.
-
-In case of a replay, the same players remain and the player who had first-move privilege in the drawn round retains it.
-
-With four players, the game is played in teams of two. Teammates share wins and losses.
-
-Play proceeds as in the three-player game: each player plays two rounds in a row — one against each opponent — then gives way to their partner. Likewise, only the winner of the first round plays just once, at the start and end of the game.
-
-Players not currently in a round may advise those at the table (opponents in three-player, teammates in four-player) according to their interest; but they are forbidden to touch any game component.
-
-### PAYMENTS
-
-Each round is paid to the winner in as many tokens as holes scored, minus those of the loser. The loser also pays a **consolation** of two additional tokens to the winner, and to the other player in the three-player game.
-
-If the round is won in small bredouille, each hole won by the winner is paid double (2 tokens) and the consolation is also doubled (4 tokens).
-
-If the round is won in big bredouille, each hole is paid quadruple (4 tokens) and the consolation is quadrupled (8 tokens).
-
-Each hole won by the loser is deducted from the total and is always worth only one token.
-
-In case of a replay, the consolation price doubles the previous drawn round's price, doubling again at each successive replay.
-
-In the three-player game, the loser must additionally always pay the consolation to the non-playing player, whatever the consolation price.
-
-Moreover, after each defeat, the loser sets aside one token (sometimes two) to track the number of losses and allow later settlement of bets.
-
-All these tokens form a **queue** that is paid at the end of the game to the player who won the most tokens in rounds. In case of a tie, the queue is split equally among the winning players.
-
-The queue is not mandatory when scoring is kept in writing, but may be counted by convention.
-
-Each player then settles their outstanding bets equitably with each opponent.
-
-A **bet** (_pari_) is any round exceeding each player's contingent. The contingent is the average number of rounds played between two opponents.
-
-Thus, if two players play eight rounds, each player's contingent is four, and any round won or lost beyond four is a bet won or lost. This gain or loss is doubled since a bet won by one player is also a bet lost by the other.
-
-The first double bet is called the **postillon** and is paid 28 tokens (including 20 from the queue); each subsequent bet costs 8 tokens. This payment is made between each pair of players. With three players, it is possible to win or lose two postillons among other bets, one per opponent.
-
-Finally, the definitive settlement converts each player's winnings into chips (or another equivalent whose value was established beforehand — for example, one chip = 5 tokens).
-
-## ARTICLE XX: END OF GAME
-
-### THE ORDINARY GAME
-
-The ordinary game — also called the "tour" of trictrac — ends when a player wins their twelfth and final hole. This hole may be won through the player's own dice roll or the opponent's (helpless man, schools); the player need not leave to end the game.
-
-By prior convention, the game may be won simple or double. It is won double — in big bredouille — when a player scores all twelve holes consecutively. The second player to mark may also achieve this by taking the flag and keeping it until they score twelve holes without the first player scoring again and taking back the flag. If neither player scores twelve holes consecutively, the game is won simple.
-
-Another convention allows the game to be won quadruple if the winner was the only player to score. The second player to mark may win triple by achieving big bredouille as described above. The game is won double if both players' bredouilles are cancelled and the loser failed to score at least six holes; otherwise it is won simple.
-
-Settlement is then made according to the stakes established before the game.
-
-The game ends when the loser has paid their debt to the winner.
-
-### THE SCORED GAME
-
-As stated in Article II, the scored game consists of an agreed number of rounds. When those rounds have been played — including any replays — settlement takes place by performing the count and payments as described in Article XIX.
-
-The game ends when all debts have been settled.
-
-### APPENDIX: SCORING TABLE
-
-This table summarises the point value of all scoring events: jans and figures of the game.
-
-"J" = the player (who rolled the dice); "A" = the opponent (_adversaire_): they indicate who benefits. Numbers indicate points scored.

-
-School penalties are worth to the opponent exactly the number of points that were over- or under-marked on that move.

-# LOIS ET RÈGLES DU TRICTRAC
-
-ÉDITION 2013 COMPLÉMENT AU DICTIONNAIRE RAISONNÉ DU JEU DE TRICTRAC www.trictrac.org par Michel MALFILÂTRE (trictrac.org)
-
-Il y a deux sortes de partie au grand trictrac : la partie ordinaire et la partie à écrire.
-A l'une comme à l'autre, les lois et les règles principales du jeu sont les mêmes ; mais le but, la marque et donc les paiements sont différents.
-
-## ARTICLE I : LA PARTIE ORDINAIRE
-
-Elle se dispute entre deux joueurs, le but est de marquer le premier 12 jeux ou trous. Un trou vaut 12 points.
-
-## ARTICLE II : LA PARTIE À ÉCRIRE
-
-Elle peut se disputer à 2, 3 ou 4 joueurs en équipe ou « à la chouette ». Le but est de gagner un maximum de jetons, en jouant un certain nombre de marqués ou manches, qui est déterminé d'un commun accord entre les joueurs.
-Un marqué oppose toujours deux joueurs. A trois ou à quatre, les joueurs alternent à chaque marqué suivant un ordre défini.
-Pour gagner un marqué, il faut prendre un minimum de 6 trous et qu’un joueur s'en aille, c'est-à-dire s'arrête (voir article XV). Le nombre maximum de trous pouvant être pris n’est généralement pas limité, mais les joueurs peuvent en décider différemment.
-En cas d'égalité de trous, à partir des 6 requis, lorsqu'un des joueurs s'en va, le marqué est nul et il y a refait, c'est-à-dire que le marqué doit être rejoué aussitôt.
-
-## ARTICLE III : LE MATÉRIEL
-
-Pour jouer, on utilise un tablier appelé trictrac formé de deux tables : la table du PETIT JAN et la table du GRAND JAN. Dans la première table se trouve le petit jan de chaque joueur et dans la seconde le grand jan de chaque joueur. Le petit jan d’un joueur constitue aussi le jan de retour de l’autre joueur. Chaque jan est composé de 6 flèches, ou lames de couleur alternes.
-Le tablier comprend au total 24 cases triangulaires et 30 trous pratiqués dans les rebords et les bandes.
-Un trou est pratiqué à la base de chaque flèche. Ces trous sont destinés à recevoir le fichet de chaque joueur afin de marquer les jeux (ou trous) gagnés. Les trois trous situés sur chaque bande latérale servent à placer les fichets au début du jeu ainsi que le pavillon.
-Outre ces trois fichets dont le pavillon, on se sert de 30 dames, 15 blanches et 15 noires (ou de deux autres couleurs différentes), de trois jetons, de deux cornets et de deux dés cubiques aux faces numérotées de 1 à 6.
-
-Par ailleurs, la partie à écrire se joue avec des jetons utilisés pour les paiements, ou bien avec un papier et un crayon permettant d'établir un compte de jetons.
-
-## ARTICLE IV : POSITION DE DÉPART
-
-Au début de la partie, on empile toutes les dames en deux talons distincts, l'un formé des dames blanches et l'autre des dames noires.
-Chaque talon est constitué vis-à-vis de l'autre sur une case de coin située contre une des deux bandes latérales extérieures appelée alors bande de départ et qui deviendra éventuellement par la suite la bande de sortie.
-Chaque joueur devra utiliser les dames du talon le plus proche de lui. Les coins situés contre l’autre bande latérale extérieure sont les coins de repos. La douzième case de chaque joueur, en comptant le talon pour la première, constitue donc son coin de repos ou simplement appelé : coin.
-On place les fichets dans les 3 trous de la bande de départ, le pavillon occupant le trou central. On dispose les trois jetons contre cette bande entre les deux talons.
-
-## ARTICLE V : LA PRIMAUTÉ DU DÉ
-
-Pour déterminer celui qui va jouer en premier au début d'une partie, chaque joueur jette un dé avec un cornet et celui qui a amené le plus fort nombre prend généralement les dames blanches et commence en jouant les deux nombres ainsi obtenus.
-Une autre méthode peut être employée : un joueur lance les deux dés avec un cornet et le joueur se trouvant placé le plus près du plus fort dé, jouera en premier les deux nombres ainsi obtenus.
-Dans les deux cas, si les dés amenés sont semblables, il faut jeter à nouveau les dés.
-On ne peut donc pas commencer une partie par un doublet (double).
-A chaque relevé, la primauté appartient par privilège à celui qui a sorti en premier toutes ses dames ou qui s'en est allé (voir articles VIII et XV).
-
-A la partie à écrire, à deux joueurs, la primauté alterne à chaque marqué ; à trois ou quatre joueurs, elle appartient à celui qui reste pour affronter un nouvel adversaire.
-Lorsqu'il y a refait, le joueur qui avait la primauté au marqué nul précédent, la conserve pour ce refait et pour les éventuels suivants, en cas de refaits successifs.
-
-## ARTICLE VI : JETER ET JOUER LES DÉS
-
-Les deux dés doivent être jetés ensemble avec un cornet. Ils sont bons lorsqu’ils se posent à plat dans le trictrac, même sur une dame ou un jeton. Si un dé est cassé, posé sur une bande ou hors du trictrac, il est mauvais et les deux dés doivent être relancés.
-On peut jouer les deux nombres obtenus par les dés avec deux dames, chacune jouant un nombre, ou avec une seule dame jouant « tout d'une » les deux nombres successivement (pour 6 et as : le 6 permet d'avancer une dame de six cases et l’as une autre dame d’une case ; ou bien une seule et même dame de sept cases laquelle dame exécute alors deux sauts successifs en se reposant obligatoirement sur la première ou sur la sixième case afin d’atteindre la septième case d'arrivée).
-
-Il est obligatoire de jouer les deux nombres si cela est possible. Si on ne peut en jouer qu'un seul et qu'on ait le choix, on doit jouer le plus fort.
-
-Tout nombre non joué est pénalisé : c'est un JAN-QUI-NE-PEUT qui vaut en faveur de l'adversaire 2 points d'impuissance par nombre.
-
-Les dés ne doivent pas être relevés avant que le coup ne soit joué entièrement et tous les points marqués (écoles comprises).
-
-## ARTICLE VII : LE MOUVEMENT DES DAMES
-
-On joue ses dames toujours dans le même sens, qui est contraire à celui de son adversaire, et sans jamais rétrograder.
-Dans la marche du trictrac, les dames peuvent parcourir le tablier de leur talon jusqu'à leur coin de repos (douzième case), puis passer au retour jusqu'au talon adverse.
-On ne peut placer une dame, ou la faire se reposer pour jouer tout d'une, que sur une case vide ou déjà occupée par une ou plusieurs de ses propres dames. Exception est faite à cette règle concernant les coins de repos (voir article IX).
-Il n'est pas possible de jouer sur une case qu'occupe l'adversaire avec une ou plusieurs de ses dames.
-
-## ARTICLE VIII : LA SORTIE DES DAMES
-
-Lorsque toutes les dames d'un joueur se trouvent rassemblées dans son dernier jan ou jan de retour, elles sont sorties hors du trictrac en usant du privilège de la bande de sortie qui attribue à cette bande la valeur d'une case.
-Une dame peut être sortie par un nombre sortant qui la fait aboutir directement à cette bande et par un nombre excédant qui fait aboutir la dame la plus éloignée de la bande de sortie au delà de celle-ci. Les autres nombres ou nombres défaillants doivent être joués à l'intérieur du jan.
-
-Il est possible de sortir une dame en la jouant tout d'une. Il est permis de ne pas sortir une dame par un nombre sortant mais d'en jouer une autre à l'intérieur du jan comme un nombre défaillant si cela est possible ; mais un nombre excédant doit obligatoirement faire sortir une dame.
-
-Lors de la sortie, il faut jouer la totalité des nombres non sortants à l'intérieur du jan lorsque cela est possible. Il n'est donc pas permis de jouer l'un des nombres de telle sorte que le second ne puisse être joué autrement que comme nombre excédant. De même si un nombre ne peut être joué dans le jan à cause de la présence d'une ou plusieurs dames adverses, il n'est pas permis de jouer ce nombre comme excédant par une dame située plus près de la bande de sortie.
-
-Quand un joueur a fait sortir toutes ses dames, il gagne, pour la dernière sortante, 4 points par un coup simple ou 6 points par un doublet.
-Ensuite les dames des deux camps sont relevées et replacées à leur talon respectif ; le jeu se poursuit ainsi sans que la marque des points ne soit autrement modifiée. Par privilège, le joueur qui avait sorti toutes ses dames en premier jette de nouveau les dés et joue (primauté).
-
-La sortie des dames peut se produire plusieurs fois dans une partie.
-
-## ARTICLE IX : LE COIN DE REPOS
-
-On ne peut prendre son coin de repos que d'emblée, c'est-à-dire en y portant deux dames simultanément. De même, on ne peut le quitter que d'emblée. On doit donc l'occuper avec au moins deux dames. Il est interdit de placer ou de laisser une seule dame sur son coin de repos.
-
-Il est interdit dans quelque circonstance que ce soit de placer une ou plusieurs dames sur le coin de repos de l'adversaire.
-Un coin vide peut cependant servir de passage à une dame quelconque pour s'y reposer afin de jouer tout d'une.
-
-On peut prendre son coin naturellement, par effet, ou bien par puissance si celui de l'adversaire est vide et qu'on pourrait le prendre d'emblée. Ainsi, par privilège, on prend son
-propre coin à la place comme si on rétrogradait d'une case.
-
-Si on a la possibilité de prendre son coin à la fois par effet et par puissance, on doit le prendre par effet.
-
-Après avoir quitté son coin, on peut le reprendre dans les mêmes conditions.
-
-## ARTICLE X : LA BATTERIE DES DAMES
-
-On fait ce JAN DE RÉCOMPENSE lorsqu'une dame adverse est découverte, seule en demi-case et qu'on amène des nombres avec lesquels on pourrait couvrir cette dame avec une ou plusieurs des siennes.
-La batterie est toujours fictive, à l'état de puissance ; elle ne s'opère jamais en réalité. Aucune dame n'est déplacée.
-
-On peut battre d'une, de deux ou de trois façons :
-
-- On bat d'une façon lorsqu'on ne peut couvrir cette dame que par un des nombres directs obtenus par les dés, ou par les deux nombres réunis.
-- On bat de deux façons lorsqu'on peut couvrir la dame par l'un et l'autre nombres directs, ou par un nombre direct et les deux nombres réunis.
-- Enfin, on bat de trois façons lorsque pouvant couvrir la dame par l'un et l'autre nombres directs, on le peut aussi par les deux nombres réunis.
-
-De par sa nature, le doublet ne permet de battre une dame que d’une ou de deux façons seulement :
-
-- On bat d’une façon par un nombre direct ou par les deux nombres réunis.
-- On bat de deux façons par un nombre direct et par les deux nombres réunis.
-
-On ne bat une dame que d’une seule façon par un doublet même lorsqu’on dispose sur une case de deux dames pouvant couvrir cette dame adverse.
-
-Plusieurs dames peuvent être battues lors un même coup.
-Pour chaque dame battue et pour chaque façon de la battre, ce jan de récompense vaut 2 points par un coup simple ou 4 points par un doublet lorsque cette dame se trouve placée dans un des grands jans ; si la dame battue se trouve dans un des petits jans ou un des jans de retour, chaque façon vaut 4 points par un coup simple ou 6 points par un doublet.
-
-Les jans de récompense doivent être marqués par le joueur qui les réalise (sous peine d'être « envoyé à l'école », voir article XVI).
-
-Pour battre une dame adverse par les deux nombres réunis, on doit bénéficier d'un repos pour battre. C'est une case où doit aboutir l'un ou l'autre nombre afin de pouvoir porter, fictivement, le second sur la dame à battre. Cette case doit être vide, ou bien déjà tenue par son propre camp, ou encore être occupée en demi-case par une dame adverse, laquelle est alors également battue.
-
-On fait un JAN-QUI-NE-PEUT lorsque pour battre une dame adverse par les deux nombres réunis on ne trouve pas de passage libre et qu’on est alors obligé de se reposer sur une case pleine tenue par l'adversaire. La batterie s'effectue alors « à faux » et c'est l'adversaire qui gagne pour ce jan-qui-ne-peut autant de points qu'on en aurait gagné si on avait battu « à vrai ».
-
-Une dame battue à vrai ne peut l'être à faux dans un même coup. Mais plusieurs dames peuvent être battues en même temps : alors certaines peuvent l'être à vrai et d'autres à faux.
-
-Les points obtenus pour les batteries à vrai doivent se marquer avant ceux donnés pour les batteries à faux à l’adversaire qui devra les marquer en temps utile sous peine d’être envoyé à l’école (voir article XVI).
-
-## ARTICLE XI : LA BATTERIE DU COIN
-
-On fait ce jan de récompense lorsqu'on a pris son coin de repos, que celui de l'adversaire est vide et qu'on amène des nombres avec lesquels on pourrait prendre d'emblée ce dernier sans dédoubler son propre coin, c'est-à-dire sans se servir des deux dames qui le tiennent.
-
-Comme la faculté de prendre le coin adverse n'existe pas, on le bat, ce qui vaut 4 points par un coup simple et 6 points par un doublet. Cette batterie ne peut jamais s’effectuer à faux puisqu’elle se réalise avec les deux nombres directs et jamais par les deux nombres réunis.
-
-## ARTICLE XII : JANS DE DÉPART
-
-Il y en a trois : le JAN DE DEUX TABLES, le JAN DE MÉZÉAS et le JAN DE SIX TABLES. Ils ne peuvent être réalisés qu'au début d'une partie, d'un marqué ou d'un de leurs
-relevés éventuels.
-
-### JAN DE DEUX TABLES
-
-Lorsqu'au commencement d'une partie, d'un marqué ou d'un relevé, n'ayant encore que deux dames abattues, on amène des nombres avec lesquels on pourrait placer une de ces dames sur son propre coin de repos, vide, et l'autre sur celui de l'adversaire, alors on fait un jan de deux tables si ce coin est également vide ; mais on fait un contre-jan de deux tables si l'adversaire a déjà pris son coin.
-
-Dans le premier cas, cette batterie des deux coins vaut pour soi 4 points par un coup simple et 6 points par un doublet ; dans le deuxième cas, cette batterie à faux vaut le même nombre de points pour l'adversaire.
-
-### JAN DE MÉZÉAS
-
-Lorsqu'au commencement d'une partie, d'un marqué ou d'un relevé, ayant pris son coin avec deux dames seulement abattues, on amène le coup suivant un ou deux as, on fait alors un jan de mézéas si le coin adverse est vide ; mais on fait un contre-jan de mézéas si l'adversaire a déjà pris son coin.
-
-Dans le premier cas, cette batterie du coin vaut pour soi 4 points par un as et 6 points par le doublet ; dans le deuxième cas, cette batterie à faux vaut le même nombre de points pour l'adversaire.
-
-### JAN DE SIX TABLES ou JAN DE TROIS COUPS
-
-Lorsqu'au commencement d'une partie, d'un marqué ou d'un relevé, ayant garni d'une dame quatre de ses six premières flèches (cases 2 à 7) lors des deux premiers coups, on amène au troisième des nombres avec lesquels on pourrait garnir les deux autres flèches, alors on fait un jan de six tables ou jan de trois coups. Ce jan vaut 4 points dans tous les cas puisqu'il ne peut être réalisé par un doublet.
-
-On n'est point obligé de garnir effectivement ces deux flèches : on a la faculté de jouer ce coup de la manière qu'on préfère.
-
-## ARTICLE XIII : PETIT JAN, GRAND JAN & JAN DE RETOUR
-
-### LE PLEIN
-
-Un jan est plein lorsqu'un joueur occupe chacune des six cases de ce jan avec au moins deux de ses dames.
-
-Chaque joueur peut faire le plein de son petit jan, de son grand jan et de son jan de retour.
-
-Le plein d'un jan peut être rompu puis refait. Il est possible de faire successivement au cours d'une partie le plein de plusieurs jans différents ou du même.
-
-### REMPLIR
-
-On remplit un jan lorsqu'on amène des nombres qui permettent d'achever le plein en y apportant la dernière dame.
-
-On peut remplir d'une, de deux ou de trois façons :
-
-- On remplit d'une façon lorsqu'on peut couvrir d’une dame la dernière demi-case par un nombre direct ou par les deux nombres réunis en jouant tout d'une.
-- On remplit de deux façons lorsqu'on peut couvrir cette dernière demi-case par l'un et l'autre nombres directs ou par un nombre direct et les deux réunis.
-- Enfin, on remplit de trois façons lorsque, pouvant la couvrir par l'un et l'autre nombres directs, on le peut aussi par les deux nombres réunis.
-
-Chaque façon de remplir vaut 4 points par un coup simple et 6 points par un doublet.
-
-Pour pouvoir remplir un jan de plusieurs façons, il faut nécessairement qu'il n'y manque qu'une seule dame puisque seule la dernière dame apportée remplit effectivement ; on ne remplit donc que d'une seule façon en faisant la dernière case d'emblée ou en couvrant dans le même coup les deux dernières demi-cases.
-
-Le doublet, par sa nature, ne permet tout au plus que deux façons de remplir.
-
-On ne remplit pas effectivement un jan lorsque, pouvant y faire le plein par un nombre, on doit le rompre pour jouer l'autre. Lorsque ainsi on « remplit en passant », on ne doit rien marquer. On n’est donc pas tenu d’effectuer ce remplissage.
-
-On ne peut remplir son jan de retour en utilisant ou en comptant comme façon de remplir l'une des deux dames qui tiennent son coin de repos car ce serait le dédoubler, ce qui est interdit.
-
-Après avoir marqué les points pour le remplissage du jan, il est obligatoire de remplir effectivement avec une ou deux dames, sous peine de fausse case et d’école (voir article XVII).
-
-Si on peut remplir de plusieurs façons, on remplit effectivement avec la dame de son choix et on est libre de jouer l’autre à sa guise.
-
-### CONSERVER
-
-On conserve le plein d'un jan lorsqu'on peut jouer les deux nombres amenés sans le rompre, c'est-à-dire sans se servir d'aucune des douze dames qui composent ce plein.
-
-La conservation d'un plein vaut 4 points par un coup simple et 6 points par un doublet. Il ne peut y avoir plus d’une seule façon de conserver.
-
-On peut user du privilège de conserver par impuissance lorsque, le plein réalisé, la disposition du jeu ne permet pas de jouer l'un ou les deux nombres. Seul le nombre 6 permet cette conservation puisque les nombres inférieurs peuvent tous être joués à l'intérieur du jan, quitte à rompre le plein.
-
-Par privilège, on peut conserver le plein de son jan de retour grâce à la sortie d’une, de deux ou de trois de ses dames.
-
-Comme pour le remplissage, il est obligatoire de conserver effectivement le plein d'un jan lorsque il est possible de jouer sans le rompre, sous peine de fausse case et d’école (voir article XVII).
-
-## ARTICLE XIV : JANS INTERDITS
-
-Il est interdit de placer une de ses dames dans le petit jan ou le grand jan de l'adversaire tant que celui-ci a la possibilité matérielle de remplir ce jan avec les dames dont il dispose.
-Cette interdiction cesse donc normalement dès que l'adversaire a passé suffisamment de dames au delà des cases qui lui restent à faire pour remplir ce jan, de manière que ces dames ne puissent plus servir à faire ce plein qui est ainsi devenu impossible à réaliser faute de dames.
-Ainsi l'adversaire ne pouvant plus réaliser le plein de ce jan, on a le droit d'y jouer en y plaçant une ou plusieurs de ses propres des dames.
-
-Par contre, en jouant tout d'une, il est toujours possible d'utiliser les cases vides du grand jan adverse (y compris le coin), même s'il peut encore être rempli, afin de s'y reposer pour passer une dame dans le jan de retour, dès lors que ce dernier n'est plus interdit.
-
-## ARTICLE XV : LA MARQUE
-
-On doit toujours marquer les jeux et les points qu'on gagne avant de toucher ses dames pour jouer ou avant de jeter les dés pour le coup suivant si ces points proviennent du coup de l'adversaire (jan-qui-ne-peut, contre-jans, écoles).
-
-La marque des points s'effectue au moyen des jetons. Pour 2 points, on place le jeton de son côté, à la pointe de sa deuxième flèche ou entre sa deuxième et sa troisième flèche ; pour 4 points, à la pointe de sa quatrième flèche ou entre sa quatrième et sa cinquième flèche ; pour 6 points, à la pointe de sa sixième flèche ou contre la bande transversale ; pour 8 points, de l'autre côté de cette bande, dans son grand jan ; et pour 10 points, contre la bande latérale de son grand jan ou à la pointe de la flèche de son coin de repos. 12 ou 0 points se marquent contre la bande de départ, entre les deux talons, comme au début de la partie.
-
-12 points font un jeu ou trou. Si les 12 points du jeu ont été marqués d'affilée à partir de zéro au talon, c'est-à-dire sans que l'adversaire n'ait marqué aucun point pendant cette série, le jeu est gagné bredouille et vaut 2 trous. Cet avantage du jeu double est valable aussi bien pour le premier joueur à marquer que pour le second. Le premier marque avec un seul jeton et peut gagner le jeu bredouille tant que son adversaire ne marque rien. Mais alors, si ce dernier marque, il le fait avec un double jeton nommé « bredouille » et continue de marquer ainsi tant que le premier joueur ne marque pas de nouveaux points. S'il marque ainsi au moins 12 points, il gagne le jeu bredouille en second. Mais auparavant, si le premier joueur vient à marquer à nouveau, il débredouille son adversaire en lui ôtant un des deux jetons et alors aucun des joueurs ne peut plus gagner le jeu bredouille. Par conséquent, lorsque les deux joueurs ont chacun une marque avec un simple jeton, le jeu sera nécessairement gagné simple par l'un ou l'autre joueur.
-
-La marque des jeux s'effectue au moyen des fichets.
-Chaque joueur marque les jeux qu'il a gagnés en faisant progresser son fichet dans la série de trous pratiqués dans les bandes à la base des douze flèches de son petit jan et de son grand jan. Le premier trou se trouve à la base de son talon et le douzième et dernier à la base de son coin de repos.
-
-Les trous acquis doivent se marquer avant de toucher aux jetons. Le cas échéant, on démarque ensuite le jeton (bredouillé ou non) de l'adversaire en le remettant à zéro au talon. Puis, on démarque également son jeton (bredouillé ou non) si on a obtenu juste 12 points ; ou bien on marque l'excédent, appelé points de reste, avec un jeton à la manière normale.
-Si, lors du même coup on donne des points à l'adversaire, celui-ci devra ensuite les marquer en partant de zéro avec un ou deux jetons selon qu'on a marqué ou non des points de reste.
-On peut gagner plusieurs jeux, simples et doubles, dans un même coup.
-
-A la partie à écrire, le marqué peut être gagné simple, double ou quadruple selon que les trous qui le composent ont été ou non pris d'affilée (les autres marqués multiples sont rares et ne peuvent se jouer que par convention).
-Si les trous n'ont pas été pris d'affilée, le marqué est simple. Si au moins 6 trous ont été pris d'affilée, le marqué est gagné en petite bredouille et compte double. Si au moins 12 trous ont été pris d'affilée, le marqué est gagné en grande bredouille et compte quadruple.
-Comme pour le jeu bredouille, cet avantage est valable pour le premier ainsi que pour le second joueur à marquer des trous. Le second joueur prend alors le pavillon qu'il met à l'emplacement initial de son fichet dans la bande de départ. Si le premier joueur gagne de
-nouveaux trous, il ôte le pavillon à son adversaire et le remet dans le trou central. Alors le marqué sera nécessairement gagné simple par l'un ou l'autre joueur.
-
-## ARTICLE XVI : LA TENUE
-
-Lorsqu'on gagne un ou plusieurs jeux grâce aux points obtenus par son propre coup de dés, on a le choix entre tenir (rester) ou user du privilège de s'en aller. Mais si les points qui donnent le ou les trous proviennent du coup de l'adversaire (jan-qui-ne-peut, écoles), on doit obligatoirement tenir.
-
-Quand on tient, après avoir marqué son ou ses trous, on démarque le cas échéant son adversaire, on marque éventuellement ses points de reste et on continue de jouer normalement. L'adversaire marque ensuite les points que pourrait lui rapporter ce coup (voir article XV).
-
-Quand on décide de s'en aller, après avoir marqué son ou ses trous, on prévient verbalement son adversaire de son intention, car celui-ci peut s'y opposer en cas de faute ou d'école. Quand ce dernier a agréé verbalement ou en commençant à rompre son jeu, on démarque alors tous les jetons, et les dames des deux camps sont toutes relevées et remises au talon. Seuls les trous gagnés restent acquis aux joueurs. Aucun point de reste ne peut être
-marqué et l'adversaire ne peut pas marquer de points ou de trous pour ce coup. La partie reprend comme au début et, par privilège, le joueur qui s’en est allé a la primauté du dé pour ce relevé . Il rejette donc les dés et joue.
-
-A la partie à écrire, à partir du moment où un joueur a marqué au moins six trous, si l'un ou l'autre joueur s'en va, le marqué est terminé.
-Le gagnant est alors celui qui a marqué le plus de trous. En cas d'égalité, le marqué est nul et il y a refait.
-Ainsi, pour gagner une grande bredouille, il convient donc de toujours tenir à partir du sixième trou, acquis en petite bredouille, jusqu'à l'obtention du douzième et pouvoir s’en aller ; sinon on continue à jouer pour un treizième trou ou davantage si nécessaire ou si on le souhaite. Il faut aussi que l'adversaire ne marque pas un trou et s’en aille, ce qui terminerait ainsi le marqué simple ; mais dans le cas où celui-ci déciderait de tenir, il pourrait gagner aussi une grande bredouille en jouant sans jamais s’en aller jusqu’à l’obtention de douze trous, ou plus si on en a déjà soi-même marqués davantage ou simplement s’il le souhaite. Alors il doit pouvoir s’en aller pour terminer le marqué.
-
-## ARTICLE XVII : LES FAUTES ET LES ÉCOLES
-
-Il y a trois types de faute à ce jeu :
-
-1°) Les simples fautes, peu préjudiciables à l'adversaire et dont certaines peuvent être rectifiées normalement (exemples : jouer hors tour, lancer les dés hors de la table, bousculer accidentellement la disposition du jeu, ou bien oublier de marquer une école). On n'encourt aucune sanction pour ces fautes.
-
-2°) Les fautes de case ou fausse case. Elles peuvent être préjudiciables et se produisent lorsqu'on ne joue pas ses dames aux cases où l'on devrait en fonction des nombres obtenus ou si l'on viole une loi du jeu en jouant ses dames d'une manière interdite (lois relatives au coin de repos, aux jans interdits, au remplissage et à la conservation). Les fautes de case peuvent susciter une école lorsqu’on a marqué des points pour un jan et qu’on ne le réalise pas effectivement alors qu’on y est obligé par la règle (ex : marquer pour remplir ou pour conserver et ne pas le faire). Alors, en plus du respect que l'on doit à la règle : « dame touchée, dame abandonnée, dame jouée », sauf si on a prévenu en disant : « j'adoube », on doit se soumettre à la décision de l'adversaire quant à l'éventuelle rectification de la faute et à la manière de le faire.
-
-L’adversaire doit signaler la ou les fautes avant de jeter les dés pour son propre coup ; il a la liberté de rectifier cette ou ces fautes selon son intérêt, tout en respectant les règles, ou bien de laisser le jeu tel quel sans rectification. Lorsqu’on a pris son coin par puissance alors qu’on pouvait le prendre par effet, on peut être empêché par l’adversaire de le prendre lors de ce coup si la faute est reconnue et qu’il est possible de jouer autrement. Si par fausse case on a couvert une dame en demi-case, on peut aussi être empêché de la couvrir lors du même coup si la faute est reconnue.
-
-3°) Les fautes de marque sont toujours préjudiciables ; elles ont lieu lorsqu'on oublie de marquer des points ou des trous, lorsqu'on en marque trop, ou lorsqu'on les marque incorrectement. On peut alors être pénalisé et « envoyé à l'école » par l'adversaire. Cette faute ou école, est consommée lorsqu'on a jeté les dés ou touché ses dames pour jouer ou encore lorsqu'on a trop avancé son jeton de marque et qu'on l'a lâché. Dans certains cas, l’école est consommée dès qu’on a fait une déclaration intentionnelle (s’en aller, école, invitation à jouer).
-
-L'école rapporte autant de points à l'adversaire qu'on en a marqué en moins ou en trop lors d'un coup. De plus, dans ce dernier cas, l'adversaire rétablit correctement la marque en supprimant les points qu'on a indûment marqués. En marquant ces points d'école, ou juste après l'avoir fait, l'adversaire doit le signaler en disant: « Ecole ! » ou « tant de points d’école ».
-
-Nul n'est tenu de marquer une école, on ne fait donc pas « école d'école ». Mais si on la marque, elle doit l'être dans son intégralité sous peine de rectification si l'adversaire le désire. On peut aussi forcer le joueur fautif à rectifier correctement sa marque, sans marquer l'école.
-
-On fait une fausse école lorsqu'on marque, soit incorrectement une école, soit une école qui n'existe pas. C'est donc une école que l'adversaire joueur peut marquer normalement à son avantage.
-Il y a augmentation d’école, lorsqu’un joueur a fait une école que son adversaire a marquée et que, pensant que ce dernier s’est trompé, il démarque cette école et les marque à son profit pour fausse école ; mais l’adversaire, persistant à croire l’école justifiée, démarque alors le joueur, rectifie la première école et ajoute encore à son profit les points pour cette deuxième école (des points marqués pour la soi-disant fausse école). L’affaire pourrait continuer selon le même scénario indéfiniment si les joueurs n’en venaient alors à une franche explication.
-
-A tout moment un joueur peut demander à son adversaire la raison des points qu’il marque (pour école ou autres cas) ou qu’il lui enlève. Ce dernier doit alors s’expliquer.
-
-On ne fait pas école de trou en marquant simple un jeu gagné bredouille. Mais on fait école de points pour les trous qu’on omet de marquer en raison des points gagnés ou pour les trous marqués en trop pour des points non gagnés.
-
-Les points d'école se marquent après tous les autres.
-
-## ARTICLE XVIII : LE DÉROULEMENT DES COUPS
-
-Pour que le coup soit régulier, chaque joueur doit obligatoirement agir dans cet ordre :
-
-Dès la fin du coup de l’adversaire :
-
-1. Le cas échéant, marquer les jan-qui-ne-peut ou les contre-jans de l'adversaire.
-2. Le cas échéant et si on le souhaite, marquer les écoles de l'adversaire et le signaler en disant : « École ! » ; éventuellement rectifier les fausses cases et la marque.
-
-Ensuite :
-
-3. Jeter les dés pour son coup. Le cas échéant, l'adversaire marque alors les écoles qu'on a faites relativement aux 1° et 2°. Règlement des fausses écoles et augmentations d’école.
-4. Le cas échéant, marquer pour les jans de départ, les jans de récompense (batteries des dames et du coin), les jans remplis ou conservés, ou les points pour la sortie.
-5. Le cas échéant, décider de tenir ou de s'en aller :
-
-- Tenir : démarquer les points et marquer éventuellement ses propres points de reste.
-- S'en aller : l'annoncer puis rompre son jeu après accord de l’adversaire. Ensuite, relever ses dames, démarquer tous les points et jeter de nouveau les dés pour jouer (sauf si la partie ou le marqué est terminé).
-
-6. En cas de sortie : relever ses dames, ne pas démarquer les points des joueurs et jeter de nouveau les dés pour jouer.
-7. Jouer les deux nombres obtenus par les dés si on le peut.
-
-C'est alors à l'adversaire de jouer selon le même processus.
-
-8. Le cas échéant, marquer les écoles que l'adversaire a pu faire, relativement à son 1° et 2°, dès qu'il a jeté les dés, ou rompre ceux-ci pour procéder à la rectification de la marque.
-
-Le non-respect de cet ordre de jeu est une faute, qui peut éventuellement être pénalisée par l'adversaire.
-
-## ARTICLE XIX : LA PARTIE À ÉCRIRE
-
-### LE DÉROULEMENT DE LA PARTIE À TROIS OU QUATRE JOUEURS
-
-Le nombre de marqués choisi pour la partie doit être un multiple du nombre de joueurs participants, de sorte qu'un joueur puisse rencontrer chacun de ses adversaires autant de fois que ceux-ci se rencontrent entre eux.
-
-A trois joueurs, on tire au sort ceux qui vont jouer le premier marqué.
-
-Ensuite, c'est celui qui tire le plus fort nombre qui commence avec les dames blanches et joue les deux nombres obtenus.
-
-Pour le deuxième marqué, le gagnant est remplacé par le troisième joueur, mais la primauté du dé appartient à celui qui est resté à la table.
-
-Pour le marqué suivant, le troisième joueur reste à la table mais les autres alternent.
-
-Chacun joue ainsi deux marqués de suite avec des adversaires différents. Seul le gagnant du premier marqué ne joue qu'une seule fois au début de la partie et à la fin.
-
-En cas de refait, les mêmes joueurs restent pour rejouer et celui qui avait la primauté du dé au marqué nul, la conserve.
-
-A quatre joueurs, on joue en équipe de deux. Les équipiers partagent les gains et les pertes.
-
-On procède comme pour trois joueurs et chacun joue deux marqués de suite, un contre chaque adversaire, et cède ensuite la place à son partenaire. Pareillement, seul le gagnant du premier marqué ne joue qu'une seule fois, au début et à la fin de la partie.
-
-Les joueurs qui ne participent pas au marqué en cours peuvent conseiller ceux qui sont à la table (adversaires à trois joueurs ou équipiers à quatre) selon leur intérêt ; mais il leur est interdit de toucher aux éléments du jeu.
-
-### LES PAIEMENTS
-
-Chaque marqué est payé au vainqueur autant de jetons qu'il a acquis de trous, déduction faite de ceux du vaincu. Ce dernier paye en outre une consolation de deux jetons supplémentaires au vainqueur ainsi qu'à l'autre joueur si la partie se joue à trois.
-
-Si le marqué est gagné en petite bredouille, chaque trou acquis par le vainqueur est alors payé double (2 jetons) ainsi que la consolation (4 jetons).
-
-Si le marqué est gagné en grande bredouille, chaque trou acquis par le vainqueur est alors payé quadruple (4 jetons) ainsi que la consolation (8 jetons).
-
-Chaque trou acquis par le vaincu est déduit du compte et ne vaut toujours qu'un seul jeton.
-
-En cas de refait, le prix de la consolation est le double de celui du marqué nul précédent. Il double à chaque refait successif.
-
-A trois joueurs, le vaincu doit toujours payer de surcroît la consolation à celui qui n'a pas joué ce marqué, quel que soit le prix de cette consolation.
-
-De plus, à chaque défaite subie, le vaincu met un jeton (parfois deux) de côté pour en indiquer le nombre et permettre le règlement ultérieur des paris.
-
-L'ensemble de ces jetons forme une queue qui revient à la fin de la partie au joueur ayant gagné le plus de jetons lors des marqués. En cas d'égalité, cette queue de jetons doit être divisée équitablement entre les joueurs gagnants.
-
-Il n'est pas obligatoire de recourir à cette queue de jetons lorsque la marque est tenue par écrit, mais on peut la compter par convention.
-
-Ensuite, chaque joueur règle équitablement les paris qu'il a perdus avec chacun de ses adversaires.
-
-On appelle pari tout marqué qui excède le contingent de chaque joueur. Ce contingent correspond à la moyenne des marqués joués entre deux adversaires.
-
-Ainsi, si deux joueurs s'affrontent en huit marqués, le contingent de chacun est de quatre, et tout marqué gagné ou perdu par un joueur au delà de ces quatre est un pari gagné ou perdu. Ce gain ou cette perte est double puisqu’un pari gagné par un joueur est en plus un pari perdu pour son adversaire : si un joueur gagne cinq marqués, l’autre n’en peut gagner que trois.
-
-Le premier double pari s'appelle le postillon et se paie 28 jetons, dont 20 de queue ; chacun des paris suivants se paie 8 jetons. Ce paiement s'effectue entre chaque joueur. A trois joueurs, il est ainsi possible de gagner ou de perdre deux postillons entre autres paris, un par adversaire.
-
-Enfin, on procède au règlement définitif de la partie en convertissant les gains des joueurs en fiches, ou en tout autre équivalent, dont la valeur a été préalablement établie par les joueurs (une fiche peut, par exemple, valoir 5 jetons).
-
-## ARTICLE XX : FIN DE LA PARTIE
-
-### LA PARTIE ORDINAIRE
-
-La partie ordinaire, appelée aussi le « tour » de trictrac, est terminée quand un joueur obtient son douzième et dernier trou. Ce trou peut être obtenu grâce aux points gagnés par son propre coup de dé ou par celui de l’adversaire ; il n’est pas nécessaire de pouvoir s’en aller pour terminer le tour.
-
-Selon convention préalable, la partie peut être gagnée simple ou double. Elle est gagnée double, c’est-à-dire en grande bredouille, lorsqu’un joueur réussit à marquer les douze trous d’affilée. Le second joueur à marquer peut jouir aussi de cette faculté en prenant le pavillon et en le gardant jusqu’à parvenir à marquer les douze trous sans que le premier joueur ne marque à nouveau et ne lui enlève alors le pavillon. Au cas où aucun des joueurs ne réussit à marquer les douze trous d’affilée, la partie est gagnée simple.
-
-Une autre convention permet de gagner la partie quadruple quand le gagnant a été le seul à marquer. Alors la partie est gagnée triple par le second joueur à marquer s’il réalise la grande bredouille comme indiqué précédemment. La partie est gagnée double si, tous les joueurs étant débredouillés, le perdant n’a pas réussi à marquer au moins six trous, sinon elle est gagnée simple.
-
-On procède alors au règlement en fonction de l’enjeu établi avant le début de la partie.
-
-La partie est terminée lorsque le perdant s’est acquitté de sa dette envers le gagnant.
-
-### LA PARTIE À ÉCRIRE
-
-Comme indiqué à l’article II, la partie à écrire consiste en un certain nombre de marqués convenu à l’avance entre les joueurs. Lorsque ces marqués ont été joués, ainsi que les éventuels refaits, on procède au règlement de la partie en effectuant le compte et les paiements comme indiqué à l’article XIX.
-
-La partie est terminée lorsque toutes les dettes ont été réglées au(x) vainqueur(s).
-
-### ANNEXE : TARIF
-
-C’est le tableau récapitulatif de la valeur en points de toutes les rencontres : jans et figures de ce jeu.
-
-Lire « J » pour le joueur (celui qui a lancé les dés) et « A » pour l’adversaire : ils désignent le bénéficiaire. Les chiffres indiquent le nombre de points gagnés.

-# Trictrac Rules — Quick Reference
-
-This document summarises the rules of grand trictrac based on the 2013 Malfilâtre edition ([full text](refs/laws_and_rules_of_trictrac.md)).
-
-French terms follow the mapping in [vocabulary.md](refs/vocabulary.md).
-
----
-
-## 1. Board and Starting Position
-
-- 24 triangular fields (_flèches_ / _cases_), numbered 1–24 from each player's perspective.
-- 4 quarters of 6 fields: **small jan** (1–6), **big jan** (7–12), **opponent's big jan** (13–18), **return jan** (19–24, exit zone).
-- Field 12 (White) / 13 (Black) is the **rest corner** (_coin de repos_).
-- Each player starts with all 15 checkers in a stack (_talon_) on field 1.
-- Checkers always move in the same direction (White: 1→24; Black: mirror of that).
-
-## 2. Dice and Movement
-
-- Both dice are rolled together; both must be played if possible.
-- If only one can be played and there is a choice, the higher number must be played.
-- A single checker may play both dice successively — a **chained move** (_tout d'une_) — stopping on an intermediate resting field (_repos_) between the two dice.
-- **Fields are single-color**: a checker may only land on an empty field or one already occupied by own checkers.
-- Landing on a field with ≥ 1 opponent checker is **forbidden** (blocked field).
-- An unplayed number is a **helpless man** (_jan-qui-ne-peut_): 2 points penalty per unplayed die, credited to the opponent.
-
-## 3. The Rest Corner (Field 12 / 13)
-
-- Must be entered **simultaneously** (_d'emblée_): exactly 2 checkers must enter together.
-- Must be vacated simultaneously: exactly 2 checkers must leave together.
-- Always holds ≥ 2 checkers while occupied; a single checker there is forbidden.
-- Two ways to take the corner:
-  - **By effect** (_par effet_): normal die values land exactly on it.
-  - **By puissance** (_par puissance_): the opponent's corner is empty; the player could land exactly on the opponent's corner, but by privilege he takes their own instead (as if stepping back one field).
-- If both by-effect and by-puissance are possible, by-effect takes priority.
-- An empty corner may serve as a resting field during a chained move (not a landing).
-- Placing checkers on the **opponent's** corner is always forbidden.
-
-## 4. Scoring: Points and Holes
-
-- Points are tracked with tokens (0–11); **12 points = 1 hole** (_trou_).
-- A **hole won bredouille** (_bredouille_) counts as **2 holes**: the active player scored 12 consecutive points from zero without the opponent scoring anything in between. The second player to start marking takes a double token (the _pavillon_ / flag) and can also win bredouille.
-- The ordinary game ends when one player reaches **12 holes**.
-
-## 5. Scoring Events (Jans)
-
-All point values: normal roll / double.
-
-### 5a. Opening Jans (first rolls of a setting only)
-
-| Jan                   | Condition                                                                                | Points                               |
-| --------------------- | ---------------------------------------------------------------------------------------- | ------------------------------------ |
-| **Two tables jan**    | First 2 checkers deployed; roll covers both rest corners; opponent's corner is empty     | 4 / 6 (to player)                    |
-| **Contre two tables** | Same, but opponent has already taken their corner                                        | 4 / 6 (to opponent, as false hit)    |
-| **Mezeas jan**        | Corner just taken (2 checkers); next roll shows one or two aces; opponent's corner empty | 4 per ace / 6 for double (to player) |
-| **Contre mezeas**     | Same, but opponent's corner is occupied                                                  | 4 / 6 (to opponent)                  |
-| **Six tables jan**    | After 2 rolls a checker is on 4 of the first 6 fields; 3rd roll could complete all 6     | 4 (always; not possible on a double) |
-
-### 5b. Jan Filling and Conserving
-
-A jan is **full** (_plein_) when all 6 of its fields hold ≥ 2 own checkers.
-
-- **Filling**: the last checker is brought in to complete the jan.
-  - Up to 3 ways: each direct die value covering the last field, or the combined sum (chained move).
-  - Each way: **4 / 6** points.
-  - Doubles allow at most 2 ways.
-  - "Filling in passing" (player must break the jan to play the other die) scores nothing.
-- **Conserving**: both dice can be played without disturbing any of the 12 checkers of the full jan.
-  - Worth **4 / 6** points (at most one way).
-  - Conservation by helplessness (_par impuissance_): only die value 6 triggers this (smaller values can always be played within the jan by breaking it).
-  - The full return jan may be conserved by exiting one or more checkers.
-- After marking points for filling, the player **must** actually fill the jan with the appropriate checker(s) — failure is a false move and a school.
-
-### 5c. Hitting (_Jan de Récompense_)
-
-Hitting is **always fictitious**: a checker is "hit" when a die value could cover an opponent checker on a half-field (_demi-case_), but **no actual checker moves**. The opponent's checker stays.
-
-**True hit**: a die (direct or combined sum) fictitiously covers the opponent checker.
-
-- In the **small jan table** (fields 1–12): **4 / 6** points per way.
-- In the **big jan table** (fields 13–24): **2 / 4** points per way.
-
-Ways to hit:
-
-- **1 way**: only one direct die, or only the combined sum, covers the checker.
-- **2 ways**: both direct dice cover it, or one die + the combined sum.
-- **3 ways**: both dice + the combined sum (requires a normal roll; doubles max at 2 ways).
-
-**Combined-sum hit** requires a free **resting field** between the two dice stops: the field must be empty, own, or a single opponent checker (which is then also hit).
-
-**False hit** (_à faux_): the combined sum could hit but no valid resting field exists (all intermediate options are full opponent fields). The opponent gains the points the player would have scored.
-
-- True-hit points are always marked before false-hit points.
-- A checker already hit truly cannot also be hit falsely in the same move.
-- Multiple checkers may be hit simultaneously (some true, some false).
-
-**Corner hit**: player holds their own corner; opponent's corner is empty; the dice could simultaneously take the opponent's corner. Worth **4 / 6** points. Never false.
-
-### 5d. Exit
-
-- When all 15 checkers are in the return jan (fields 19–24), the player may exit.
-- The exit rail counts as one additional field value.
-- **Exact exit**: die value brings the checker directly to the exit rail — allowed.
-- **Overflow** (_nombre excédant_): die value would carry the farthest checker past the rail — must exit.
-- **Failing number** (_nombre défaillant_): die cannot reach or overflow — must play within the jan.
-- A player may choose not to use an exact exit value and play within the jan instead — but overflow must always exit.
-- It is forbidden to deliberately play a die within the jan to force the second die to be played as an overflow (using a checker closer to the exit).
-- When the last checker exits: **4 points** on a normal roll, **6 points** on a double.
-- After exit: checkers reset; the player who exited keeps first-move privilege for the new setting.
-
-## 6. Forbidden Jans
-
-A player **may not** place a checker in the opponent's small jan or big jan as long as the opponent can still materially complete a full jan there (i.e., enough of their own checkers remain to fill it).
-
-Exception: during a chained move, an empty field in the opponent's big jan (including their empty corner) may serve as a resting field to pass a checker into the return jan.
-
-## 7. Sequence of Play
-
-Each turn follows this order:
-
-1. Mark opponent's helpless man points or contre-jans from the **previous** move.
-2. Mark opponent's schools; rectify false moves if any.
-3. **Roll dice.** Opponent may mark schools for steps 1–2.
-4. Mark own points: opening jans, hits, fills, conserves, exit.
-5. Decide to **stay** (_tenir_) or **leave** (_s'en aller_) if a hole was won on own roll.
-6. If exiting: reset checkers, keep token positions, roll again.
-7. Play both dice.
-
-Points and holes must always be marked **before** touching checkers for the next move.
-
-## 8. Staying or Leaving
-
-After winning one or more holes on **own dice roll**, the player chooses:
-
-- **Stay** (_tenir_): mark holes, reset opponent token to zero, mark remainder points, continue.
-- **Leave** (_s'en aller_): announce it; opponent agrees or raises a fault. All checkers and tokens reset to zero; only holes remain. Player who left has first-move privilege in the new setting. Remainder points are forfeited; opponent scores nothing for that move.
-
-If the winning points come from the **opponent's** roll (helpless man, schools), the player **must** stay — leaving is not an option.
-
----
-
-## 9. Schools (Marking Penalties) — _Not Yet Implemented_
-
-Schools are penalties for marking errors. They are worth exactly the number of points over- or under-marked on the faulty move. They are marked last in the turn sequence.
-
-Key rules:
-
-- A school is committed once dice are rolled or a token has been advanced too far and released.
-- The opponent is never obliged to mark a school — but if they do, it must be marked in full.
-- **False school**: incorrectly claiming a school — itself becomes a school for the opponent.
-- **School escalation** (_augmentation d'école_): dispute over a school that escalates back and forth.
-- No "school of school" exists (marking a school is never itself penalised).
-- No school of holes for marking a bredouille hole as simple; a school of points applies for forgetting holes due to earned points.
-
----
-
-## 10. The Scored Game (_Partie à Écrire_) — _Not Yet Implemented_
-
-The scored game is played for an agreed number of **rounds** (_marqués_) and supports 2, 3, or 4 players (the 3/4-player format is called _chouette_).
-
-### Goal of a Round
-
-- A player must score at least **6 holes** and then **leave** to win the round.
-- If both players are tied at ≥ 6 holes when one leaves, the round is **drawn** (_refait_) and replayed immediately.
-- Winner of a round = player with the most holes after a leave.
-
-### Bredouille in the Scored Game
-
-- **Small bredouille** (_petite bredouille_): ≥ 6 consecutive holes → round counts **double**.
-- **Big bredouille** (_grande bredouille_): ≥ 12 consecutive holes → round counts **quadruple**.
-- The second player to score holes takes the flag (_pavillon_) at their peg. If the first player scores again, they take back the flag, cancelling both bredouilles.
-
-### Payments
-
-Each round is settled in tokens:
-
-- Winner receives (winner's holes − loser's holes) tokens, plus **consolation** of 2 tokens.
-- Small bredouille: each winner hole worth 2 tokens; consolation = 4.
-- Big bredouille: each winner hole worth 4 tokens; consolation = 8.
-- Loser holes always deducted at 1 token each.
-- In 3-player games, the non-playing player also receives consolation from the loser.
-- Replays double the consolation price each time.
-
-A **queue** accumulates tokens from each defeat and is paid at game end to the player with the most tokens.
-
-**Bets** (_paris_): rounds played beyond each player's average (the _contingent_). The first double-bet is the **postillon** (28 tokens, including 20 from the queue); each subsequent bet costs 8 tokens.
-
-### Multi-Player Rotation (3 or 4 Players)
-
-- 3 players: after each round, the winner is replaced by the third player; first-move privilege stays with the player who remained.
-- 4 players: two teams of two; each player plays two rounds in a row then gives way to their partner.
-- Non-active players may advise (opponents in 3-player, teammates in 4-player) but may not touch game components.
