Prior to the match, both teams will have a five-minute warm-up period at the net.
PLAYERS' POSITIONS
At the moment the ball is contacted by the server, each team must be within its own court (except the server).
Players are free to position themselves anywhere within their court. There are no positional faults.

PLAYING FAULTS
The referees judges the faults and determine the penalties according to the rules.
If two or more faults are committed successively, only the first one is penalized.
If two or more faults are committed by two opponents simultaneously, a double fault is declared, and the rally is replayed.

PLAYING THE BALL
Each team is entitled to a maximum of three contacts to return the ball to the opponents.
These contacts of a team include not only intentional but also unintentional contacts with the ball by a player.
Blocking constitutes a team contact, and any player may make the second contact of the ball after the block.
When two non-blocking teammates touch the ball simultaneously, it is considered one contact, and any player may make the next contact.
When two blocking teammates touch the ball simultaneously, it is counted as one contact, and any player may make the second contact.
A joust occurs when players of opposing teams cause the ball to come to rest above the net through simultaneous contact. A joust is not a fault, and play continues as if the contact was instantaneous as in a block.
A player is not permitted to take support from a teammate or any object in order to reach the ball.
However, a player who is about to commit a fault may be stopped or held back by a teammate.
A player may touch the ball with any part of the body.
A served ball may not be received using the fingers in a setting action. Hands must be together touching ensuring there is not a double contact or a held ball.
Whilst in play, the ball must be contacted cleanly and not held, lifted, pushed, caught, carried or thrown.
The ball cannot roll along or come to rest on any part of a player's body.
During defensive play, the team's first contact of a hard-driven ball (an attack-hit or blocked ball traveling at a high rate of speed - not a serve), as judged by the referee, may be momentarily lifted, pushed or double contacted, during a single attempt to play the ball, provided the fingers are not used to catch and direct the ball.
A contact of the ball using the fingers (setting action) of one or two hands to direct the ball toward a teammate is a set. A player may set the ball in any direction toward his/her team's court.
If the ball is intentionally set into the opponent's court, the player must contact the ball with two hands above his/her shoulders and set it directly forward or directly backward with relation to his/her body, square of the shoulders.
A legal set directed toward a teammate that crosses the net because of elements or in the case of a spectacular play, is not a fault, regardless of the player's body position.
When contacting the ball with one hand, other than for setting the ball toward a teammate, the ball must be cleanly hit with the heel or palm of the hand (a roll shot), with straight, locked fingertips (a cobra), knurled fingers (a camel toe) or with the back of the hand from the wrist to the knuckles.
One-handed placement or redirection of the ball over the net with the fingers is a fault.
