360ball 

360ball is a new sport that utilizes the principles and properties of a circle to define a ball game. Players use a racquet to strike a ball onto a centrally placed concave disc. The court has no separate sides and players pivot 360° around the disc as directed by play. 360ball is played either by two players (singles) or by two teams of two players (doubles). www.360ball.net / www.360ball.de / www.360ball.es / www.360ball.fr
