Play othello on your phone!

Rules: two players begin with four disks placed in a square in the middle of the grid, two facing white side up, two pieces with the dark side up, with same-colored disks on a diagonal with each other. Players take turns placing disks on the board with their assigned color facing up. During a play, any disks of the opponents color that are in a straight line and bounded by the disk just placed and another disk of the current players color are turned over to the current players color. The object of the game is to have the majority of disks turned to display your color when the last playable empty square is filled.
