A friend of mine from state math team, Luyi, has a really neat geometry blog. She just linked to a game I've been trying to refind for years called Planarity. Read her comments about it here.

Planarity, in principle, is a really simple game. You get a circle of dots - vertices. Each is connected to anywhere between 2 and 5 other points with lines - edges. All you have to do is move the dots so that none of the edges cross. It's very tricky, and very fun. At the moment, I'm up to level 8.
