The goal of the game is to tip the balls off the towers! Place a large ball on the tower to make it easier for beginners or a smaller ball to improve precision shooting. Choose from an underarm or overarm throwing action or for something different, try using a frisbee! Set the target height low or high for added variety. Adjustable target height options: 89cm, 100cm, 125cm, 150cm. Tower suits balls 7cm to 16cm in diameter.
