Paddleball Paddleball was created at the University of Michigan in 1930 by Earl Riskey, a Physical Education instructor in that university. The latter is similar to a racquetball court.
Game is played with a rimless paddle and a ball slightly smaller than a tennis ball.
The object is to win the rally by serving or returning the ball so the opponent is unable to return the ball to the front wall before it touches the floor twice. Points are scored only by the serving side when it serves an ace or wins a rally.
