Note: before you start, make sure your keyboard is set at a very slow rate. Go to your CONTROL PANEL and set it to repeat 1-2 times a second.
1. Make sure you have atleast 500 NP out of the bank.
2. Go to the Dice-a-roo game.
3. On the main Dice-a-roo page is a button that says "Let's Play! (Costs 5NP). Click that once.
4. On the next page, there is a button that says "Play Dice-aroo" and shows the 5 colored dice. BEFORE you click that button, hold down your ENTER key and keep holding it. Click the button and keep holding. You will set it processing at the bottom of your browser window over and over again. Hold for a few minutes and then stop and let the game refresh. See where you are and continue. ALWAYS hold ENTER before you click again though.
5. Do this until your pet gets bored, but make sure to check your inventory for any items you won, the Neopian Lottery for any tickets you found, and your pets stats, because the game CAN raise levels.
