Look for a "Scheduled for Maintenance" sign to appear on one of the $1000 Progressive slot machines. Play the machine until it is fixed. You can get $5000 for one cherry. To get over $700 million, go to Video Poker, select "Easy Money" and the "$25.00" game. Click on the dollar bill changer. When asked, enter 9 number 9s then click "OK". The game will freeze. You will have to close it and start it again. However, when you do so you will have over $700 million and a black Visa card.
