Uno Show 'Em No Mercy is Mattel's 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 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!
