Game play starts with each player writing up to 8 customizable rules using the erasable cards and pens provided. The house rules cards are then shuffled and placed in the Wild Roller. Regular UNO™ game play kicks off the game, but when the special wild roller cards are played, players must pull the wild roller lever and the suspense begins. You never know who will have to take a customizable rule card, or you could get lucky and get UNO™ Wild Jackpot! But beware, there's also a draw 4 lurking on that wheel. UNO™ Wild Jackpot is sure to provide the most exciting, fun and suspenseful UNO™ game yet. House rule cards may be friend, foe, silly, or strange, so be ready! Players race to get rid of all their cards by matching a card in their hand with the current card shown on top of the deck. When you're down to one card, don't forget to yell UNO!
