I wonder what the rules are

So do you jump and try to catch the ball, or do you throw it? There are sure plenty to choose from!

Seems like there's only one rule: Don't leave the balls lying around on the grass!

My grandsons do this on my trampoline. They jump and the balls go flying and they laugh hysterically

@kjarn I think you have given me the definitive answer!

I think the idea is to catch the balls but of course they cant with them flying everywhere
