Heres what you do. You will need a memory card and thats it. Insert the memoy card and make a new account or use an old account. Go to the game Black Jack. Bet all your money or the most you can. Pull out your memory card and then let the dealer deal the cards. If you win put the memory card back in if you lose just reset it and do it again. I keep betting alot of money and winning a lot more becuase of this trick.

This trick allows you to get money easier and without losing any guaranteed. First, play the "Catch of the Day" slot machine and put all of your money in so you have zero dollars & zero cents remaining.(Note: it's best to play $100 machines so you won't be inserting money forever.) Then, play Maxium 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. Hence, every time you do it, you gain $700. trust me, it helps.

Easy Money
The only thing required is a controller with an auto fire feature. Go to the slots, and choose a machine. It really doesn't matter but I like the ones with the bigger payout (1000 credits or so). 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 your millions!
