Be last person standing
Hit a ball around an enclosed area. Each person can hit the ball once. Your goal is to get people out by hitting the ball and hitting the person below the waist. If they catch it you are out, if they drop it, they are out. If it hits you and you cannot hit it back, you are out.
Number of Players: 6 or more
Ages: 7 and up
Activity Level: very high
Equiptment: Ball and an enclosed area.
you should be able to hit the ball as many times as you want; the version I am familiar with entails each player being able to hit the ball only once before the ball contacts another player; after that, the ball is fair game again.
