Extra Money
Obtain a VIP card, then enter the Video Poker section. Raise the stakes to 100 dollar coins and start playing. Deposit a large amount of money without selecting any cards. Then, after the money has been deposited, press the "Pay" button. Now leave the Video Poker section after the amount being paid to you appears. Depending on how much was deposited, a few thousand or as much as a million dollars can be collected. A larger payoff will result if more money is deposited in the machine.

Slot Machine Choices
When you go to the slots area the "EUREKA" Slot Machine that's way in the back will always hit the THREE GOLD BRICKS only once which will pay off 1500 credits! (At least it works for me.)
