TEAM COMPOSITION
Each team has 15 players, 12 of whom play in any one game and three possible substitutes. During the game 6 players are in the pool with 6 exchange players on the side who can be substituted at any time.
PLAYER ROLES
There are different team configurations but generally a team has 2 forwards, 2 defenders and 2 goalkeepers. The idea is to keep possession of the ball and outwit your opponents by using skill, speed, maneuverability, and breath hold. When a team is attacking all players have no official role, which means also the goalkeeper can attack like anyone else.
PLAYER EQUIPMENT
Players are wearing a cap, mask, snorkel and fins. A ball filled with salt water is used to score a goal. The goals are placed on the bottom of each side of the pool and are made of steel. The goals look like a basket.
START OF THE GAME
The teams start at each end of the pool with one hand on the wall. The ball is in the middle of the pool, at the bottom. When the referee sounds the buzzer both teams race to get possession of the ball.
