Tchoukball is an indoor team sport where players pass and carry a ball up a small court with the intention of putting it into a basket located on either end of the court. Teams may score on either basket and may not make physical contact with any member of the opposing team.

Tchoukball is an indoor team sport played with two teams of nine players on a court with trampolines at either end. To score, a team must throw the ball so that it hits the frame and bounces outside the trampoline area without being caught by the defending team.

The goal of tchoukball is to score more points than the opposing team at the end of regulation.

Two teams of nine players each (men or women) compete to score points. A player scores a point when he bounces the ball onto either of the two trampolines, or frames, and it touches the ground outside the semi-circle facing the trampoline. If a player of the attacking team misses the frame, or if the ball touches the ground outside the court before or after the bounce, then the defending team scores a point. Each team can score a point on either of the two trampolines.

Tchoukball was created by Dr. Herman Brandt in the 1970s because of his concern over the serious injuries athletes suffered in more aggressive sports. He believed that sports should not only form champions, but also contribute to the creation of a better and more humane society. It is designed to be played by anyone at his or her respective level, irrespective of the player's sex, age or physical abilities. He believed that "The objective of all physical activities is not to make champions, but make a contribution to building a harmonious society."
