Spaceball is a classic trampoline game invented by the Olympic Trampolinest, Eddie Cole. It is kind of like a game of 1-on-1 volleyball on a trampoline. You play in a 14 foot tall netted cage on a trampoline with a barrier between you and your competitor. There are two holes in the barrier in which you throw a ball through and attempt to land it on your opponent's floor. It may look easy for on-lookers but once you've been jumping for a few minutes you'll find out how good of shape you're really in.

1. Players take turns throwing the ball through one of the two rings.
2. If the ball touches the floor on your opponent's side, you score 1 point.
3. Reaching your hand more than halfway through a ring is a fault and scores one point for your opponent.
4. First to 7 points wins.
5. With more than two players you must rotate other people in, either trading as partners or by playing separate games.
6. Only one person on each side of the spaceball at a time.
7. No flips or acrobatics allowed.
