You can do this in the $10,000 Break The Bank. Create a player and 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 and 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.
-Look for a "Scheduled for Maintenance" sign to appear on one of the $1000 Progressive slot machines. Play the machine until it is fixed to possibly get $5000 for one cherry.
-For 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 but will have over $700 million and a black Visa card.
-Get any player with any amount of money and go to video poker slots, then click on any 100 dollar slot. Once done, click on the part of the machine that reads "Insert Bills". A screen should appear, asking how much money you want to insert. Type 200000000. This will automatically set you at a billion dollars and into the hall of fame. However, your stats will be reset.
-Do the above trick to any $100 poker machine but make sure you owe money first. When you win, the loan sharks will appear and you will have about $999,999,000.
