GAMEPLAY 

UNO FLIP is a  variation of the classic uno game with a double-sided deck. One side is the standard UNO deck (the "light side"), while the other side is the "dark side" with more challenging and aggressive action cards. During the game, a "Flip" card can be played, which forces all players to flip their hands and the draw pile to the other side. The dark side includes more powerful versions of the standard cards, such as a Draw Five or Skip Everyone card.

As always, if you are the first player to get rid of all of your cards, you win.
