There are two goals, one at each end of the swimming pool. They are like the baskets in basketball but they are on the bottom of the pool.To score a goal, you must put the ball in the basket.The ball has got salt water inside it.This makes the ball go down in the water, not up. The players mustn’t take the ball out of the water.Your mustn’t attack another player. If you do, you have to be out of the water for two minutes and your team must play with only five people, not six.
