One game I used to play in PE was wallball

You have a tennis ball and a wall, and you chuck it as hard as you can. If it hits someone on the richochet, that person has to run up to the wall and touch it before anyone can recover the ball and hit the wall with it or he's out. If you catch it on the fly (when I originally put bounce I meant bounce from the wall, not the ground), the person who threw it is either out or has to touch the wall before it's hit or they're out, either way they're basically out
