Rules of the Game
Match format, team composition, substitutes, service, net play and attacking.
Updated November 10, 2026
Format
- The winner of the pre-game coin toss decides whether their team will serve or receive.
- Each match is 3 sets to 21 rally points — a point can be won on an opponent’s serve. Teams must win by 2 points, with a 23-point hard cap.
- Games start on time, regardless of whether teams are ready, and end on time, regardless of what time they started or whether they’ve been completed.
Team Composition
- 4s leagues: teams must have 4 players on the court, with a minimum of 1 male and 1 female player on the court at all times.
- 6s leagues: teams must have 6 players on the court, with a minimum of 2 men and 2 women on the court at all times.
- All players must be present on the online roster at the time game sheets are printed.
Substitutes
- Substitute players are allowed, but must be added to the roster by noon on the day of the game.
- Any substitute players are expected to be of a similar skill level to the rest of the team.
- Substitute players deemed too advanced for the team or division may not be permitted to play by the referee or convenor.
- To be eligible for playoffs, all players must have attended a minimum of one third of the games, unless given express and demonstrable permission from league administrators.
Substitutions
- A player in the starting line-up may leave the game once and re-enter once in the same set, to their previous position. The player leaving may only re-enter in place of the player who substituted them.
- A team that is unexpectedly short during game time (regular season only) may ask players from previous games to substitute, under the following conditions:
- The opposing team and referee must be notified before the start of the match and must give permission.
- The substituting player must be an appropriate skill level for the team or division.
- The team may only invite enough substitutes to field a team.
Defaults
- Teams must be ready to begin at their designated time. Players who come early to warm up must respect groups using the gym before them.
- If after 10 minutes a team does not meet the minimum player and gender requirements, they forfeit the first set.
- If after 20 minutes they still do not meet the minimum player and gender requirements, they forfeit the match.
- Forfeited matches are recorded as 21–0.
- Teams that default more than one match may be removed from the league without refund.
Service
- The server must complete the serve within 5 seconds after the whistle, as judged by the referee.
- The ball is in play if it touches the net and goes over to the opponent’s side.
- Serves may not be blocked or immediately spiked.
- Each server is capped at five consecutive serves (advanced leagues excepted).
- Players on the serving team may not obstruct the opponent’s view of the serve, server or ball trajectory.
Net Play and Attacking
- A blocker may touch the ball beyond the net as long as they do not make contact with the net or interfere with the opponent’s play.
- Players may touch the opponent’s court with a foot, as long as the front foot is touching the centre line and does not interfere with the opponent’s ability to play the ball.
- A block contact does not count as a hit — the attacking team is entitled to 3 additional hits.
- Players may attack-hit the ball from any position or location on the court.
Player Equipment
- Knee pads are recommended.
- Only clean, non-marking indoor shoes are permitted on the court.
- Teams may provide their own ball, as long as it is better than the league’s ball and properly inflated and kept.
