The game consists of swimming (with and without the ball), egg beatering (to position a player upright in the water), and throwing, catching, and shooting the ball using a single hand. Each team consists of 6 field players and a goalkeeper. Except for the goalkeeper, players participate in both offensive and defensive roles. The 6 field players are not typically assigned a specific position, except for the 2-meter man, who is usually positioned directly in front of the opponent's goal.
