There is a "Light Side" to the deck, which plays like classic UNO™, and a "Dark Side" where penalties are super-tough. Play the FLIP card and all cards in your hand, the draw pile and draw deck are flipped over to reveal an entirely new set of numbers and colors on the opposite side! The holder of the FLIP card determines whether or not you play on the Light Side or Dark Side of the deck -- and when you switch it back around.

The Dark Side of the deck includes new action cards that really shake things up, like Draw Five and Skip Everyone cards. Strategize to rattle your competition and be the first to get rid of your cards to win. When you're down to one card, don't forget to shout "UNO!"
