A Reversi (commonly known as Othello) game for iPhone and iPod touch. You play by placing a black token on the board so that at least one of your opponents white tokens is bounded on two sides (horizontally, vertically, or diagonally) by your black tokens.
At that point all of your opponents white tokens between your black tokens reverses to black. Your opponent will place white tokens to change your bounded tokens white. The goal of the game is to finish with more black tokens than whit tokens on the board.
