The Spordas Skyfloater ball was developed for the team sport KIN-BALL. It can also be used for other cooperative games. The ball features a durable, washable, and double-stitched nylon cover, which gives it a long lifespan even after intense community use. Beneath the cover is a large latex balloon that provides the ball with its spherical shape and allows for quick inflation and deflation thanks to the large opening. It comes with an air balloon.

KIN-BALL is played with a large ball that has a diameter of 122 cm and weighs only 1 kg on a square playing field measuring 20 m on each side. It is the only team sport played with three teams of four players each, all present on the field at the same time. Each team is identified by a differently colored jersey.

The serving team calls out the color of the team they choose. The called team must accept the ball before it touches the ground and then serve in turn by calling one of the two other teams. If a team lets the ball drop to the ground, both other teams receive 1 point. Players may use their entire body to prevent the ball from touching the ground, but the throw must only be executed with the upper limbs. All four players must touch the ball during the serve.
