Experience the ultimate, chaotic version of UNO. In UNO Show 'Em No Mercy, you can stack +2, +4, +6, and even +10 cards to eliminate your opponents. If a player gets 25 or more cards in their hand, they are instantly eliminated!
The rules are brutal. You can stack draw cards, meaning if someone plays a +4, you can play a +4 to make the next person draw 8! The 7 and 0 rules apply: playing a 7 lets you swap hands with another player, and playing a 0 makes everyone pass their hand to the next player. The game ends when one player gets rid of all their cards, or everyone else is eliminated by the Mercy Rule (25+ cards).
The biggest debate in UNO history is finally settled. Can you stack in UNO No Mercy? YES!
The official uno no mercy stacking rules state that if you are hit with a penalty card, you can play a penalty card of equal or greater value to pass the penalty to the next player.
