The court is divided by a net, which is 2.43 meters high for men and 2.24 meters for women.
Each side of the court is divided by an attack line, which is placed 3 meters from the net. The zone in front of this line is called the attack zone or front zone, while the zone behind is called the defense zone or back zone.
Volleyball is played by two teams with six players each on the court. The goal is to win points by hitting the ball down onto the opponent's side of the court.
The right to serve goes to the team that last scored a point. The serving player must stand behind the back line when serving and may only step onto the court after the ball is put into play. The serve must be sent over the net to the opponent's side and may touch the net on the way over.
Matches are played best of 3 or 5 sets. To win a set, a team must reach 25 points and have at least a two-point lead. If the score is 24-24, the set continues until one team has a two-point lead. Points are scored on every rally, regardless of which team is serving.
When a team receives the ball from the opponents, they may touch the ball a maximum of three times before it must be sent back over the net.
Points are also awarded if the opponent hits the ball out of bounds or into the net.
Each team has six players on the court at a time. The players rotate their positions clockwise, so all players get to play all positions and serve. The only exception is the libero, which is described in more detail below.
The rotation means that players are placed in different spots on the court, and therefore the lineup will vary depending on where the players are in the rotation. The rotation occurs every time the serve changes sides.
When serving, players must position themselves according to the rotation, and as soon as the ball is served, they may move freely on the court. During the serve, the back row players must be positioned farther from the center line than the front row players, and the positioning is determined by foot placement in relation to the numbers in the graphic above.
The setter is typically the second player to touch the ball and acts as the team's playmaker in attack.

The setter's primary task is to set the ball up for the other players so they can finish the attack.
A good setter must also be able to perform a so-called 'dump', where the ball is quickly placed over the net to surprise the opponents' defense.
Due to the rotation, the setter spends half the time in the back row when the opponent is serving. Often, another player is pulled back to receive the serve so the setter can quickly move to the net and organize the attack.
The middle blocker positions themselves in the middle of the net and has the main responsibility for blocking attacks in the center of the court.
Height and strength are important qualities for a middle blocker, as the main task is to block the opponents' attacks. The middle blocker must also be able to help with blocks on the sides as needed.
When the ball crosses the net, the middle blocker will often move back behind the attack line near the setter to participate in quick attacks and create uncertainty for the opponents.
The outside hitter is positioned on the left side and is often the player who gets the most attack opportunities during a match.
In addition to finishing many attacks, the outside hitter is also important in receiving the opponent's serve. After receiving, the outside hitter moves out to the left side to be ready to finish the attack.
When the ball is on the opponent's side, the outside hitter must be aware of the opponent's attackers and help the middle blocker with blocks.
The opposite is positioned opposite the setter in the rotation, which is where the position gets its name. The opposite must be able to substitute for the setter if the setter is not in position.
The opposite often has an important role in both attack and defense and must be able to finish attacks from the right side as well as help with blocks.
The libero was introduced in 1999 to strengthen the defensive play. The libero can be substituted freely and wears a jersey with a clearly different color than the rest of the team.
The libero is often a player with great technical skills, especially in defense and reception, and does not need to be as tall as the other players, since the libero does not participate in attacks at the net.
The libero is substituted in for one of the back row players (position 1, 5, or 6) and may only play in these positions. If a position change is needed, it must be done via a substitution out and in. Substitution with a libero does not count towards the maximum number of substitutions per set.
The libero often replaces the blocking players when they rotate back into the back zone, where they typically lack the technique to return the ball effectively.
Volleyball is played with a light and elastic ball, and players often wear knee pads and sports shoes with good support. Net and referee stand are standard equipment for official matches.
Volleyball is a team sport that requires cooperation, speed, and tactical understanding. With clear rules, exciting positions, and the opportunity for both exercise and competition, volleyball is popular all over the world.
