In the Attract mode, press the Extra Ball button when the display shows 'In memory of Joe Joos jr.'

Tapp the Extra Ball button while starting :
1) Pinbot Poker to make Pinbot pull out an ace of clubs from his sleeve.
2) Keno to get Pinbot to make all 25 squares match for 99,000,00.
3) Slot machine to get Pinbot to change reels to 'Light Extra Ball'.
4) Roll the Dice to get Pinbot to flip the dice to 12 x Dice Bonus.
5) Casino Run to hear a cow moo, and now each shot to 'spin the reels' during Casino Run changes the first bomb into another award (only works once per Casino Run).
6) End of Ball Bonus (with 2x to 5x) to get an extra bonus multiplier.
These cheats are not sure to work all the time, but when they do you'll hear Pinbot saying : 'Look over there', 'Look Hally's Comet', or 'Look there's Rudy'.
