Each player takes turns matching one of their cards with the color or number of the card turned up at the top of the pile. 
To get rid of their cards as quickly as possible, they can play Action cards to slow down their opponents, such as Pass, Reversal and Color Change Joker cards. 
UNO FLIP!

When a player places the Flip Action card, they turn over all the cards in their hand, draw pile and pile to reveal new numbers and new colors on the back! 
The person who placed the Flip card can then choose to play on the “white” or “black” side and can return the game to the original direction whenever they wish. 
Develop a strategy to thwart your opponents' plans and be the first to get rid of all your cards to achieve victory.
