    General Rules

    • GAME TIME IS FORFEIT TIME. If a team does not have the minimum number of players required to start signed in by game time, the shorthanded team will forfeit the game.
    • A game shall consist of two 12 minute halves with a 3 minute half-time. The clock will run continuously throughout the first 22 minutes of the game. During the last 2 minutes, the clock will stop on all official’s whistles.
    • Time-Outs. Each team will receive 1 time-out per half and for each overtime period. Time-outs do not carry over between periods.
    • Overtime. If a playoff game ends in a tie, a 3 minute overtime period will play. All personal fouls will carry over for each overtime period. The clock will run continuously for the first 2 min of the overtime period and stop on all official’s whistles during the last minute of play.
    • Substitution. You may enter the pool area anywhere. Request a substitution from an official after a basket is made, when a throw-in is about to occur, at time-out, when a penalty has been called or between halves. The official will let you know if you can substitute.
    • Starting the Game. A coin flip will give the teams the option of the ball in the first half or second half. Overtime periods will start with another coin flip. The ball is put in play at the far end line.
    • Throw-ins. On a throw-in the ball must be passed before a try on goal. The defense must be at least 3 feet away until the thrower passes or moves with the ball. The thrower has 5 seconds to pass or begin moving with the ball.
    • Jump Ball. A jump ball is called if opposing players have equal possession of the ball, or when opposing players simultaneously knock the ball out of bounds. The ball is put in play using the alternating possession arrow.
    • Out of Bounds. When a ball goes out of bounds, it goes to the opposite team at a spot near where it went out.
    • Free Throws. Free throws are not awarded to players after a personal foul; fouls are counted to three and then after the third team foul, the opposing team is awarded one point.
    • Moving with the Ball. To legally move the ball you may carry it, pass it, bump it with your tube, or splash the ball. You do not have to dribble the ball.
    • Remain in tubes. Participants may not play the ball while out of their tube. If a player falls out of their tube, they may next play the ball only after they have returned to his/her tube in a sitting position.
