Court size is 7x14m divided in two sides of 7x7m by a net. Other court sizes can be adopted (6x12m, 8x16m or 9x18m) to adapt the game to the playing conditions.
 

Regular Volleyball ball is used: for beginners, a lighter ball can be used; for children a specific ball, lighter and bigger, can be used.
 

Refereeing is basically done by the players themselves or one referee is appointed by the Organisation (in tournaments).
 

A rally starts by a service (the ball is hit by hand towards the opponents’ side) from behind the end-line (or closer to the net if agreed before the match).
 

The team is entitled to a maximum of three hits for returning the ball. Block contacts are not counted. One player cannot play the ball 2 times consecutively.
 

To stimulate long rally-play only major technical faults will be called. Only in attacking the ball must be played exactly according to the rule of "short contact".
 

The ball can be played with any part of the body. The ball can be touched or hit but can not be caught in any way.
 

On winning the service, a new player must serve according to a pre-set serving-order.
 

Unlimited players' substitutions are allowed when the ball is out of play.
 

A match consists of rally-point (each rally scores one point) sets to 25 points (win should be by two points difference without limitation). The number of sets is decided by the organiser or by the participants (1, 2, 3 winning sets). In case of a draw, a deciding set to 15 points should be played (win should be by two points difference without limitation).
 

Teams switch court sides during the set, when the leading team reaches 13 points and also between sets. In the deciding set, teams change court sides when the leading team reaches 8 points.
 

One time-out (30 sec.) is allowed per set, per team.
 

Net touch is not sanctioned if it does not interfere with the game.
 

Interference with players of the opponent team (touching, holding, pushing, etc.) is not allowed.
 

Any fault is sanctioned by loss of rally, with its consequences (the opponent team scores a point and gains the right to serve, or continues to serve).
