But the point of the game is not to figure out the math behind it. It's to find the sets.

Of course, if you like figuring out the math and that's how you make the game fun for yourself, then you don't have to read the link. That's fine. But I don't see how it's cheating to read about the math behind the game.

I guess I'd call it learning, not cheating! wink
