Mattel UNO Show 'em No Mercy Game

UNO Show 'em No Mercy is the most brutal UNO game yet! It has more cards with tougher penalties (draw 10 cards anyone?) and new rules that will have players stacking, swapping and drawing more cards than ever before! 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! And if you manage to get down to one card, don't forget to yell "UNO!"
