Game suggestions for two highly competitive jellies?

I’m visiting lucillelucillelucille this winter and we’re having the first annual Bannessirympics. That’s Banana, Vanessir and Olympics all in one. Booya grandma!

Anyway, we need suggestions for indoor games (since it will be too cold outside) that we can compete against each other in.

So far, we’ve come up with darts, pool, bowling, Yahtzee, air hockey and a few others.

Please give us some suggestions for indoor games/activities where the winner will be vunessuh there can be a winner and a loser. Thanks! :)
