Get rich quickFirst, play the "Catch of the Day" slot machine and put all of your money 
in so you have zero dollars & zero cents remaining. It's best to play 
$100 machines so you won't be inserting money forever.) Then, play 
Max. bet and during the spin, press Start and change your game. Press 
reset purse. The game will give you $1000 for restarting & however 
was left in the machine as your credits. Every time you do it, you gain $700.

For this tip, the only thing required is 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'll want to have about 200 credits into the machine, 
just to be safe. Move your hand to 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. In no time you'll have 
millions!
