[He nods. And then sort of makes a golden ring appear with a twist of his hand, and then disappears it again.]

The ball is there, actually. Most of the time. Least at first-- the way you set it up is fairly simple. Start at a copper, then a silver. Double or nothing. You move the cups a little slower, make an obvious gesture. They win just enough to feel like you're playing fair. Then once the gold is enough to make it worth it, you slip the ball out from under it before they pick one. No answer is right. You win.
