When shooting on net becomes redundant, try this. Put two or three players in the middle of a relatively large circle composed of other players. Give the players in the circle two or three balls to start. The objective of the game is to hit the players in the middle by shooting the ball at them. You can introduce more balls into the game if it moves too slow. If a player manages to hit a player inside the circle, they trade places. Introducing one-touch shooting is another way to add speed to the game.
