Ludo

  • double roll if all pawn either in start or end
  • allow pawn #n to move out if rolled n
• 1-n players
• PvP, PvC, CvC

turn-based system

• roll dice
• choose which pawn to move (pawn #n can move out of home if rolled n or rolled 6)
• move pawn animation
  • also checks if passing via the pivot point - if so, move to home path
• if reached end, measure self, number of finished pawns is the outcome
• check for collisions
  • no collision if landed on safe spot
  • if collision with self, apply symmetric beam splitter between self pawns at that spot
  • if collision with other player, first perform dark measurement on self (i.e., is finite or zero)
    • positive (finite) -> measure other player, collapse them and send back to start if finite
    • false (zero) -> no collision, self collapsed to zero amplitude on that stop.
• if rolled 6, or reached end and measured finite, or collision that sent opponent back to start, get extra turn
• otherwise next player's turn
