This Game is meant for Boy Scouts.
Decide for yourself if it is appropriate for your younger scouts or not.

2 benchs 
1 or more volleyballs, rubber balls, or nerf balls

Lay out a rectangular play area such as a basketball court. 
Place a bench at each end. 
Mark a goalkeeper-only zone around the bench to keep opposing players from being too close. 

There are many alternate versions of this game.
General Play:

• Divide into two teams, one on each side of the court center line.
• Each team chooses a goalkeeper to go and stand on the bench at the far end of the court. They will throw the ball to him and score a point when he catches it.
• The ball is passed between players until it is thrown to the goalkeeper for a score.

Alternative Rules to Mix In:

• Players wear colored jerseys and can roam the entire court.
• Players can not move once they have the ball.
• If the ball touches the ground, whichever team was in possession of it, loses possession.
• When a goalkeeper catches the ball, he can immediately throw it at an opposing player and turn him into a goalkeeper if hit below the waist.
• All players stay on their side of the center line. They can either try to score a goal or hit someone on the other team below the shoulders with the ball to force them out to the penalty box. When their team scores a goal, the first 1, 2, or 3 people can return from the penalty box.
• Use multiple balls.
• Use different colored balls. Yellow can only be used to tag someone. Blue can only be used to score a goal.
• Make up additional rules.
