Racquetball is a competitive game in which each player uses a strung racquet to serve and return the ball. Racquetball is played by two or four players. When played by two, it is called singles and when played by four, doubles. A non-tournament variation of the game that is played by three players is called cut-throat.
The objective is to win each rally by serving or returning the ball so the opponent is unable to keep the ball in play. A rally is over when a player (or team in doubles) is unable to hit the ball before it touches the floor twice, is unable to return the ball in such a manner that it touches the front wall before it touches the floor, or when a hinder is called.
Points and Outs
Points are scored only by the serving side when it serves an irretrievable serve (an ace) or wins a rally. Losing the serve is called a sideout in singles. In doubles, when the first server loses the serve, it is called a handout and when the second server loses the serve, it is a sideout.
Match, Game, Tiebreaker
A match is won by the first side winning two games. The first two games of a match are played to 15 points. If each side wins one game, a tiebreaker game is played to 11 points.
