1.No crotch Shots.
3.(Only in a less hardcore version) No hitting in the face.
4.One person, the pitcher, who can be any person, or usually the lead singer if being played at a concert, tosses the ball into the pit.
5.The people in the pit, the area where the ball is thrown, fight to get the ball and toss it back to the pitcher.
6.Getting the ball back to the pitcher 3 times means you win. If being played outside, then that person becomes pitcher.
7. Interceptions and stealing the ball are allowed, but no knocking out in order to get the ball.
Recommendation: Use a tennis ball, its bounce and such makes it perfect for the game.
*throws ball into crowd*
Pit: FUCK YEAH!
