Othello

Othello is a computer adaptation of the board game of the same name. On a eight by eight grid the player and computer take turns to place a marker on the board. Markers must be placed to enclose one or more markers of the opponent in one or more direction. Any enclosed markers change symbol to be identical to the enclosing marker symbol. After 60 moves, when the board is full whoever has most markers on the board wins the game.
