The name of this game is a play on words. Pool means the swimming pool and pool billiards game at the same time. You have a number of turtles in a swimming pool and you need to play pool using them as the balls. However, your goal is different from the standard pool game. You need to mate turtles of the same color making them collide with each other. As in pool, you only can hit the white turtle directly. Other turtles must be hit by the white one to start moving.
