What is Racquetball?

Racquetball is an indoor court sport invented in 1950 by Joe Sobek at a Greenwich, Connecticut YMCA. It combines elements of handball, squash, and paddleball on a fully-enclosed court where every surface — four walls, ceiling, and floor — is in play. Players use a short stringed racquet (55 cm max length) to hit a hollow rubber ball (5.7 cm diameter). The server bounces the ball once behind the service line, hits it against the front wall, and the returner must hit it before it bounces twice. Rallies end when a player fails to return the ball to the front wall before it bounces twice. Racquetball is played 1v1 (singles), 2v2 (doubles), or 3-player 'cutthroat'. Peaked in popularity in the USA in the 1970s-1980s. The International Racquetball Federation (IRF) and USA Racquetball govern the sport; racquetball has been part of the Pan American Games since 1995.

How it works

Objective

Win the match by winning 2 of 3 games — first player to 15 points (game 1-2) or 11 points (tiebreaker game 3) wins each game.

Match structure

Match: best of 3 games. Games 1-2 to 15 points, game 3 (tiebreaker) to 11. Only server scores (rally scoring in newer rules). Server wins point = keeps serving; loses = side-out to opponent.

Rules

Basic rules

  • Service

    Server bounces ball once behind service line; hits front wall on the fly; ball must land past short line for legal serve.

  • Rally

    Ball must hit front wall on each return (may hit any other wall first).

  • Two-bounce rule

    Ball may bounce at most once on floor before return.

  • Only server scores (traditional)

    If server loses rally, no point — becomes 'side-out'; opponent serves. USA Rally scoring: every rally scores.

  • Game to 15 (1-2), 11 (tiebreak)

    First player to 15 (or 11 in game 3) wins the game; win by 1 (not 2).

  • Match: best of 3 games

    First to win 2 games wins match.

  • Mandatory eye protection

    USA Racquetball requires goggles at all sanctioned events.

Advanced rules

  • Hinder / avoidable hinder

    If player blocks opponent's swing or path, ref calls hinder (replay) or avoidable hinder (loss of rally).

  • Screen serve

    Serve passes so close to server that receiver can't see — replay (fault).

  • Three-wall serve

    Serve hitting front wall + 2 sidewalls = out.

  • Doubles alignment

    Non-serving doubles partner stands in service box (2×5 ft) — head against sidewall to avoid interference.

  • Cutthroat

    3-player rotation: 1 server vs 2 defenders; server scores individually; if server loses rally, next player serves.

Scoring

First to 15 points (games 1-2), 11 points (tiebreaker) wins the game; traditional scoring: only server scores.

  • Referee (pro)
  • Line judges (pro finals)
  • Self-officiated (rec)

Strategies

  • Control center court

    Position yourself in center court after serve — dominant position for reaching returns.

  • Attack the front-wall low

    Kill shots (hit inches above front wall on floor) end rallies.

  • Serve variety

    Rotate between drive (low), lob (high), and Z serves to unbalance receiver.

  • Ceiling shot to reset

    When defensive, hit ball to ceiling — forces high descending return.
