Color Rush is a cross between Othello, and Chinese Checkers. The board starts as a sea of colored gems. You start as the white gem on the lower left corner. The opponent is the black gem (some little player that lives deep within your phone).One by one you click on colored gems that stand adjacent to your white gem. Click it and it becomes white. But for every colored gem you click, your iPhone Gnome turns around his to black. The object is to have more white gems than black ones.
