Fistball is a team sport in which two teams compete against each other on two half-fields, similar to volleyball. They are separated by a center line and a net stretched between two posts up to two meters in height. If the net or posts are touched by either a player or the ball during play, this is considered an error.
Each team consists of five players, with players trying to play the ball across the net from one half of the field of play to the opponents' half – using only their arm or closed fist (unlike in volleyball where open hands are allowed) – in a way in which the opponents cannot return it. After clearing the net, the ball may be contacted up to three times by the five players on each team – with a bounce being permissible before each contact (also unlike in volleyball where no bounce is allowed), but no repeat hits by any individual player within the three attempts. Similar to volleyball, the three hits are ideally used to save, set and spike the ball back into the opponents half, in that order.
