Indoor Volleyball Rules



Players may play on one team in each league.  A team competes with 6 players, however, minimum number of players is 3.  All players must be registered and checked in before the game begins.

Rock/paper/scissors determines which team receives the choice of either the serve or the court. 

The best of three games will win matches. Each non-deciding game will be won by the team that first scores 25 points with a minimum two-point advantage (no scoring cap). If there is a deciding game, it will be won by the team that first scores 15 points with a minimum two-point advantage (no scoring cap). Point will be scored on each rally. If the receiving team wins the rally, they score a point and gain the serve.

Rest periods between games of a match shall be no longer than 2 minutes.

Each team is permitted 2, 30-second team time-outs per game.  Time-outs may be requested to an official only when the ball is dead and are not in effect until the official recognizes the time-out with a whistle or hand signal and vocal command.

Players are asked to wear tennis shoes for their own protection.  We will not permit anyone to play with hard-soled shoes or sandals.  Participants with casts (especially hand or wrist) will not be allowed to participate.  Leave all jewelry at home.  The IM Department strongly recommends that no jewelry be worn in IM competition.

Do not chase loose volleyballs into other courts while play is in progress.


The server has 5 seconds to begin the serve from the time the official signals the serve with a whistle.

The service zone includes the full width of the 9-meter area behind the end lines.  The server may move freely within the service zone.  At the moment of the service hit or takeoff for a jump service, the server must be completely in the service zone and not touching the court (end line included) or the playing service outside the zone.  After the service, the player may skip or land outside the zone including the court.

If the server tosses the ball and does not serve it he does NOT need to let it bounce before he re-tosses it.

Net Service Is In Play. A served ball that hits the net does not result in the service team losing its serve.  The net serve is considered in-play, unless 1) it does not continue over the net or 2) lands outside the opposing team’s court-side untouched by the opposing team.         


The receiving team is not allowed to block or spike a served ball.

A spiker must contact the ball on his/her own side of the net, but may in the course of the follow through reach over (but not touch) the net.

Back line players while inside the attack zone (10 feet from the net) may not play the ball directly into the opposite court if contact is made when any part of the ball is above the top of the net.

The team that has affected the block shall have the right to three more contacts, with the blocker having the right to make the first of the three allowable hits.


A ball hit into the net, may still be kept in play (up to 3 hits) provided that a player does not make contact with the net.

Players may not touch the net.  If 2 opposing players touch the net simultaneously, the ball is declared dead and is replayed.


A ball is out of bounds and becomes dead when it:

  1. Touches any part of a backboard or its supports hanging in a vertical position
    1. The IM West or IM East vertical glass backboards and supporting structures are considered out of bounds.
  2. Makes contact with the side walls (including the slanted walls of the running track at IM East).

A ball hitting the ceiling or an overhead obstruction (lights, fan, or basketball hoop lying horizontally) above a playable area shall remain in play provided the ball contacts the ceiling or obstruction on the side of the net that is occupied by the team that last played the ball.


The ball must be returned over the net in 3 hits or less. 

It is legal to contact the ball with any part of the body as long as the ball rebounds immediately.  It may not "lay" against the body or forcefully kicked.  If a player touches the ball or the ball touches a player, it is considered as a play on the ball.  Except in the following case: A ball touching the body more than once in succession is legal when played off a hard-driven spiked ball, or blocked and played again by the blocker.

If 2 players on the same team contact the ball simultaneously, it counts as one contact, and any player may play the ball.

One may play the ball twice during a volley, but not twice in succession, unless played directly off a block.

When a ball touches a boundary line, it is considered in play.

Rule of Three (3):  If a ball is played by more than two players on a team, the ball must be played by both genders.  The order is not relevant. If three contacts of the same gender occur the official will blow the play dead and award the opposing team the serve and the point.


Players are not permitted to scoop, hold, and lift or push the ball.  The ball may never be contacted with an open-hand underhanded motion.

In addition, during the first hit of the team, except when serving, the ball may contact various parts of the body consecutively, provided the contacts occur during one action.

An official may (at their own discretion) penalize a team one point or loss of serve for intentionally delaying the game.


Each team may choose to rotate extra players into the server's position on a continuous basis. In all substitutions participants must inform the official on the net and wait for the official to initiate the substitution.   

All substitutions must be made within a 15-second time limit.  If changing time exceeds 15 seconds, a team time-out will be charged.  If a team has none of its 2 allotted team time-outs remaining, point or side-out will be awarded to the other team.  An injury substitution is not considered as one of the 2 allowable time outs.

If a player arrives after the first game of the match has started, and her/his name is on the roster, that player will be allowed to play in the game as a substitute if the team uses regular substitutions.


Unsporting conduct includes actions which are unbecoming to an ethical, fair, and honorable individual. it consists of acts of deceit, disrespect or vulgarity, and includes taunting.
