The Game

Racquetball is a sport similar to squash, played with racquets and a hollow rubber ball on a special court. The sport was invented by Joe Sobeck in 1949 incorporating rules of squash and handball. Contrary to other sports, shoes, walls, the floor and ceiling of the court are considered to be part of the playing area.
Matches are generally played by two or four players, although there are versions with three players.
