Difficulty: Moderately Challenging
Step1
Assemble two teams of six players each, along with five substitute players for each team. Also have three people act as referees, two in the water and one poolside.
Step2
Equip each team with fins, snorkels, masks and ear protectors. Use two steel baskets as goals, one for each team set at the bottom of the pool on either end.
Step3
Place a ball slightly larger than a softball filled with saltwater into the bottom center of the pool. Have the referee blow a whistle to start play. Each team of 12 players dives into the pool. The first to reach the ball starts play.
Step4
Attempt to get the ball into the opposing team's basket to score a goal. The ball may be passed between players, side-to-side or up-and-down, but cannot leave the water. Getting the ball past the goalie and into the basket results in a score.
Step5
Substitute players as needed while play is going on. Underwater rugby is a fast-paced game, extremely challenging and players need frequent breaks. Rotate players as needed.
Step6
Play two 15 minute halves. Take a four minute half-time break. The team scoring the most goals by the end of the second 15 minute half is the winner.
