Reversi and Othello are names for an abstract strategy board game which involves play
by two parties on an eight-by-eight square grid with pieces that have two distinct sides.
Pieces typically appear coin-like, but with a light and a dark face, each side representing
one player. The object of the game is to make your pieces constitute a majority of the
pieces on the board at the end of the game, by turning over as many of your opponent's
pieces as possible.
