Mookie All Surface Pro Swingball is perfect for older children and adults wholl enjoy hitting a real tennis ball at full whack in truly competitive matches. Mookie All Surface Pro Swingball can be played just about anywhere on any surface such as grass, decking, concrete - even sand. Simply fill the base with water or sand for stability and youre ready to play. A game starts with the tether in the middle of the Swingball spiral, each player takes turns to hit the ball, one player hitting the ball clockwise, and the other anticlockwise. The ball flies around the pole and the tether moves up and down the spiral. The winner is the player to reach the top, or the bottom, of the spiral first. Mark your score dependant on who wins the game. Games can be played with one or two players. In practice mode, individuals can perfect their forehand and backhand shots. All the components pack away into the base, ideal for storage and transportation, you really can take and use this Swingball set anywhere.
