Reversi is a board game for two players, played on an 8x8 uncheckered board. There are sixty-four identical disks, which are red on one side and blue on the other. Players take turns placing disks on the board with their assigned color facing up. During a play, any disks of the opponent's color that are in a straight line and bounded by the disk just placed and another disk of the current player's color are turned over to the current player's color. The object of the game is to have the majority of disks turned to display your color when the last empty square is filled.
