State data

• piece placement -> 77bits (24 + 23 + 30 max)
  • dames
• active player -> 1 bit
• step -> 2 bits
  • roll dice
  • mark points (jeton & fichet) & set bredouille markers (3rd jeton & pavillon)
  • move pieces
• dice roll -> 4bits
• points 10bits x2 joueurs = 20bits
  • points -> 4bits
  • trous -> 4bits
  • bredouille possible 1bit
  • grande bredouille possible 1bit

Total : 77 + 1 + 2 + 4 + 20 = 104 bits = 13 * 8 (8^2 = 256) = 17.3333 * 6 (18 u64) -> 108 possible
