Kin-Ball is played with a giant ball measuring 1.22 m in diameter. The aim of the game is to throw the ball to the opposing team in such a way that they are unable to catch it before it hits the floor. All players on a team must be in contact with the ball. The server must hit the ball with one or both hands and the ball must travel in an upward or outward direction. The game requires three teams of four players. The small size of the court means that many players can play at the same time.

CST has two Kin-Balls and various halls and outdoor areas that are suitable for playing the game.
