The team that has possession of the ball has a three pass limit before being forced to shoot the ball at the rebound surface on either end of the court. Members of the other team must place themselves according to where they expect the ball to land, so that they can catch it before it touches the floor. Meantime, members of the other team look to position themselves to recover the ball after it rebounds from the rebound surface, before the ball can touch the floor. During the course of the game, the players of each team are not allowed to interfere with players of the other team: they may not intercept passes, interfere with the movements of the person carrying the ball or his team mates, or stop a defender from positioning himself to catch the ball after the rebound.
A player scores a point for his team if he bounces the ball off the rebound surface in such a manner that it cannot be caught by an opponent before it touches the floor.
A player gives a point to the other team if:
- He misses the rebound surface when he shoots the ball.
- He makes the ball bounce out of bounds.
- He shoots the ball and it bounces back, touching him.
- He sends the ball into the forbidden zone, before or after it hits the rebound surface.
