I am just going to throw Wallball out there. So much fun, and I have not played it since I was 12.
So just looking it up on the Internet, there seems to be varying rules.
The way we played was with a tennis ball or racket ball.
No teams just individuals.
A player throws a ball against a large wall. If someone catches it before it gets to the wall, the thrower is out. If someone catches it off the wall bgefore it bounces, the thrower is out. If someone tries to catch the ball off of the wall, but it bounces off of them. They have to run and touch the wall before someone retrieves the ball and hits the wall first, or pegs the guy on his way there.
