Easy Money:
Note: Requires a controller with an auto fire feature.
Go to the slots, and choose a machine. Set the bets to $5 or $10 bucks and put all of your money into
the machine. You may want to put about 200 credits into the machine, just on the safe side. Bet Max
Credits, set the a button to auto fire, get a rubberband (or something to hold the a button down) and
leave the room for a few hours. You'll have millions in no time you'll have millions!
