UNO Show 'Em No Mercy is the most brutal UNO game yet. 56 more cards, special rules and super-tough action cards make this a brutal, ruthless & unapologetic experience for all involved!The extra cards have even 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! Ohand if you manage to get down to one card, don't forget to yell 'UNO!'
