Question: what is the difference between uno and uno flip?
Answer: UNO FLIP™ plays like regular UNO®, except there are two sides to the deck of cards: a “light” side and a “dark” side. You start playing with the Light Side, but whenever someone plays a FLIP card, the deck is flipped over (as are the cards in your hand) and now everyone must play off of the Dark Side of the cards.
