UNO Show 'Em No Mercy is the most brutal UNO game yet! It has a ton more cards with WAY tougher penalties (draw 10 cards anyone?) and new rules that will have players stacking, swapping and drawing more cards than ever before! And there's even a Mercy Rule (yes, Mattel gets the irony) if things get too rough. There are two ways to win in this merciless version of the classic game: get rid of all cards OR knock all other players out of the game! Oh - and if you manage to get down to one card, don't forget to yell "UNO!"
