n.
Game similar to handball but played with racquets.
The game is played on a four-walled court with a short-handled racket and a ball larger than that used in handball. It was invented in 1950 by Joseph G. Sobek (191898), who was unhappy with the indoor racquet sports then available. By the late 1990s there were 8.5 million racquetball players in 91 countries.
