Game idea:
Two teams face each other on a court and try to hit a ball over the net into the opponent's court in such a way that the opponent cannot reach it.

Scoring a point:
A point is scored when the ball falls to the ground twice in succession in the opponent's court or the opponent is unable to return it in accordance with the rules.

Playing field:

Outdoor: 50 x 20 metres.
Indoor: 40 x 20 metres.

The playing field is divided into two halves by a net 1.90m (women) or 2.00m (men) high. A line of attack is drawn 3m away from the centre line in each half.

Number of participants:
5:5

Rules of the game:
Each rally begins with a serve and ends with the first subsequent fault. After each fault, the ball is re-set by the team that made the fault. Each player is allowed to hit the ball. To do so, the ball must be put into play in front of and behind the service line. If the ball is in play, it may be touched three times by the respective team after each net crossing. On the third touch at the latest, the ball must be passed over the net to the opponent. Before each touch by a player, the ball may bounce once on the ground, but only within the playing area. The ball is played with the inside of the outstretched forearm during defence and passing, and hit with the fist during attack or serving.

A point is scored by forcing the opponent to make a mistake. The following events are counted as errors and therefore result in a point for the opposing team:

The ball or a player touches the line/net or the posts.
The ball touches the ground outside the court.
The ball touches the ground twice in succession without a player touching it in between.
The ball is played sideways past the posts or underneath the line/net into the opponent's court.
More than three players of one team touch the ball during a turn.
A player touches the ball for the second time within a turn. If there are several touches of the ball, they must be different players.
The serving player touches or crosses the 3-metre line (service line)

The ball touches a part of the body other than the upper or lower arm or the fist. The ball may also not be touched with the palm of the hand.

Play is based on points and sets. Each mistake results in a point for the opposing team. A set ends as soon as one of the teams has scored eleven points and is leading by at least two points (if the score is 10:10, the set is automatically extended), but at the latest when one team scores 15 points. The number of winning sets can vary. In Switzerland, the game is usually played in 3 winning sets.
