"UNO Show 'em No Mercy is our 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, we get 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!"""
