XtremeReversi XtremeReversi is a two-player game. One player has the orange ball and the other plays with grey ones. The game starts with 2 orange and 2 grey discs in the center of 32 square boards. The orange plays first. You move by placing a disc in an empty square so you can flip an opponent disc to your color. You can flip every disc of the opponent which is located on vertical, horizontal or diagonal lines between you and empty cells. The game is over when the board is full of discs and no player has chance to move. You win if the most discs on the board are on your color.
