Onitama is a two-player, perfect information abstract game with a random starting set-up. On a 5x5 board, both players start with five pawns on their side, with the main pawn in the middle. Each player has two open cards that each display a possible move for any of his pieces. There is a fifth card that cannot be used by either player. On a player's turn, he chooses one of his cards, moves one of his pieces according to the chosen card, then replaces the card he used with the fifth card.
