UNO Show 'em No Mercy is the most brutal UNO game yet! Prepare for 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 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!"
