Well -- you know, I've been looking at some of the old annuals from the school, because I wanted to see what my father looked like when he was at Hogwarts. And there was this game people used to play called A.K. It's kind of like a grownup hide-and-seek with wands, almost, and it sounded really fun. And it was even older students than firsties playing it back in the old days, there were fourth and fifth years playing it.

So it's not just chess and gobstones and exploding snap.
