Musical chairs and opass the parcel and so forth are the kinds of games which adults et up kids to play. They are all about training and so forth, sticking within the rules.
Then you went out in the playground and the adults and stand back and you'd make the rules. A bit like the Mudcat. It's no fun if there aren't any rules, and part of the fun is knowing when to bend them. And bullying isn't allowed, and just spoils the game.P>
