Except for the goalkeeper, they can only handle the ball with one hand at a time. There are four periods in a game and each period is seven minutes with two-minute intervals between each one. Each period starts with the teams lined up on opposite goal lines. When the whistle blows the teams sprint toward the center pool where the referee releases the ball into the water. Whenever the whistle is blown for a foul or stop of the game, the clock time is stopped.
Physical contact is common as players maneuver position.
Substitutions can be made after a goal is scored, between periods, during timeouts, for an ejected player or during running time. The referee indicates the fouls by blowing a whistle and using hand signals to point out the direction of attack and where the ball is put into play. Last year at USU the attempt was made to organize a team, but it fell through because there weren't enough people dedicated to it. This year, the team is scheduled to play Ricks College at the end of October. The team is still struggling for strong leadership, but those already practicing don't want to see it die again.
