That's not actually addressing the point though. For most of the games so far, the person doing the cheating is Toph herself, so attracting attention to herself would only make it more likely for her to get caught.If you picture the crowd as a bunch of people from this thread, you'll see it suddenly all makes sense.
If I could, I'd add better distractions to these games but all of them would include a horny/nude Toph.
She should be distracting the crowd from you, so that you can do the cheating.
Preferably while you yourself are running the game, to con some poor suckers out of their cash.
You being the customer doesn't make a lot of sense, since anybody with half a brain would ban you after they realise that they're losing money every single time you play. Cups is trivial and the hammer-game seems to pay out no matter how badly you do.
Set you up on your own stall and scam some rubes.
