The court is 18m long and 9m wide, with each team's area being a 9m square. The net height is 2.43m for men and 2.24m for women. Some male players have a maximum reach of over 3.5m, spiking the ball from a height more than 1m above the net.

Matches are played as a 5-set match. One set is played to 25 points, and the team that wins 3 sets wins the match. If the score is tied at 24-24, the match continues until a 2-point lead is achieved. Only the 5th set is a 15-point match.

About positions
There are five positions: Outside Hitter (OH), Middle Blocker (MB), Opposite (OP), Setter (S), and Libero (L). It is standard to place players of the same position diagonally from each other in the front and back rows for Outside Hitters and Middle Blockers. The Setter is paired diagonally with the Opposite.

Opposite literally means "the other side." The name comes from the fact that they are positioned diagonally (on the opposite side) from the setter. They specialize in offense, do not receive serves, and always participate in back-row attacks even when they are in the back row. In contrast, the Libero is a player who specializes in defense. They wear a different colored uniform from the rest of the team, cannot serve or spike, and cannot set the ball using an overhand pass in front of the attack line.

In volleyball, where three players are positioned in the front row and three in the back, the team rotates clockwise by one position whenever they win the serve. Players who move to the back row cannot block, and their attacks are restricted, such as having to hit from behind the attack line (back-row attack), which adds variety to the game. Watching the game while being aware of the rotation makes it even more interesting.

A maximum of 6 substitutions per set are allowed.
A player who started the match may return to the court once during the same set after being substituted out. In this case, they can only be substituted for the player who replaced them, and this counts as two substitutions (one when leaving the court and one when returning). Note that substitutions involving the libero do not count toward the substitution limit.

Each team may request up to two 30-second timeouts per set.

This is a system that allows teams to request a video review if they disagree with a referee's decision.
There are 8 items for which a challenge can be requested: (1) ball in/out, (2) block touch, (3) antenna-related decisions, (4) server line fault, (5) net touch, (6) floor touch, (7) attack line fault, and (8) last touch.
You can request challenges until you have two unsuccessful challenges per set.
