​UNO Show 'em No Mercy game adds 56 more cards, special rules and super-tough action cards for the most brutal edition of UNO ever! ​Tougher action cards, such as Skip Everyone, Wild Draw 6 and even Wild Draw 10 make game play merciless! ​The Stacking Rule lets players pass the penalty (Draw +2, +4, +6, +10) to the next player until whoever can't play has to take all the cards combined! ​Whenever a "7" or a "0" card is played, players must swap hands with another player! ​The Mercy Rule means that if any player gets 25+ cards in their hand, they are out of the game! 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!"
