Easy money:
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.
Extra money in Break The Bank:
This trick can be done in the 10,000 Break The Bank. Create a player, then go to the game. Enter the options menu and select "Players". Choose "Replace", select another player, but do not go back to play the slots. Instead, select "Replace" again. Delete the player you had previously. Create a new player and when you go to play you should start with 10 million to 31 million. Note: If it does not happen at first, repeat those steps.
