The fact you have to pay for the prize probably more than you would pay in real life, but full disclosure it says at the very beginning that the machines are "real" so they may "malfunction" it also says this game gives out real prizes and those prizes are not free due to manufacturing and all that. So if you are shocked it cost money it does say that before the game even begins.. I also wasn't really able to get the hang of it and my butt is cheap, not about to pay a bunch of money to be duped.
