In this serviceable port of the strategy board game (based on Reversi), two players place black and white-colored discs on an 8-by-8 game board grid, alternating one each at a time. Players may select a computer or human opponent, the difficulty level, and the time limit of the game. The object of the game is to have more of your colored discs on the board by trapping your opponent’s discs and converting them to your color.
