Reversi

2 white pieces and 2 black pieces are placed to the central area of a chessboard. Two players place white pieces and black pieces to the chessboard in turn. A piece can only be placed to a position of the chessboard in the condition that the piece and other same color pieces sandwich opposite pieces in horizontal, vertical or diagonal direction. In this case, the sandwiched opposite pieces will change color (but opposite pieces sandwich by changed color pieces and other same color pieces won't change color again). If a player can not place piece, the other player continues to place piece. If both players can not place piece or the chessboard is full, game is over. One who has more pieces on the chessboard wins the game. If both have the same number of pieces, the player who first place piece loses the game.

Click an empty position to place piece if it is possible. In 1 Player game, click "Computer" button let computer place piece.
