Tchoukball is an indoor team sport. At each end there is a ‘frame’ (a device similar to a trampoline off which the ball bounces) which measures one square meter and a semicircular D-shaped forbidden zone measuring three meters in radius. Each team can score on both ends on the field, and comprises twelve players, of which seven may be on the court at any one time. In order to score a point, the ball must be thrown by an attacking player, hit the frame and bounce outside the ‘D’ without being caught by the defending team. Physical contact is prohibited, and defenders may not attempt to intercept the attacking team’s passes. Players may take three steps with the ball, hold the ball for a maximum of three seconds, and teams may not pass the ball more than three times before shooting at the frame.

Sitting volleyball (sometimes known as paralympic volleyball) is a form of volleyball for disabled athletes. In sitting volleyball, a 0.8 meter-wide net is set at 1.15 meters high for men and 1.05 meters high for women. The court is 10 x 6 meters with a 2-meter attack line. Players must have at least one buttock in contact with the floor whenever they make contact with the ball. It is also possible to block the serve and jousts are generally replayed.

The 2004  summer sensation movie, Napoleon Dynamite, has many tetherball scenes. As you can see below he also uses the regulated tetherball ball!

Tetherball is a traditional grade school game where two opponents stand opposite each other in hopes to securely spin a ball on a rope around a pole. Rules of the official ball size are unclear but can be purchased with a tetherball equipment set.

This fast past game takes from its original horse version.

T-ball is the introduction for children ages 4 and up to either baseball or softball. This sport uses a stand that holds the ball  instead of someone throwing the ball at them.
