> We give users a little bit of money each week to play with ($0.50 right now) and if they can run it up past a certain point we'll pay them out in cash. If they lose the money, we put another $0.50 in the next week. It's legal in the US since the users aren't allowed to deposit and mainly for entertainment purposes.
