UNO No Mercy rules: how to play

UNO No Mercy is UNO with the gloves off: draw penalties up to +10 that stack, hands that change owners, and elimination at 25 cards. Here are the full rules in plain English, and you can try them right away in a free game against bots.

The rules in 30 seconds

Goal of the game

As in classic UNO, you want to get rid of all your cards. No Mercy adds a second way to win: survive. Every player who reaches 25 cards is out, and if everyone else falls, the last player standing wins.

Setup

  1. Shuffle the deck and deal 7 cards to each player.
  2. Turn one card face up to start the discard pile.
  3. The rest of the deck is the draw pile.

The official boxed game has 168 cards. Mercy's base deck has 164 cards, or 188 with the expansion turned on.

Taking a turn

On your turn, play one card that matches the top of the discard pile by color, number or symbol. Wild cards can go on anything and let you pick the next color.

Draw until you can play

This is the first rule that catches people out. If you have nothing playable, you don't draw just one card: you keep drawing, one at a time, until you get a card you can play. A bad streak can hand you ten cards in one turn.

Stacking draw cards (+2, +4, +6, +10)

When someone plays a draw card on you, you can pass it on by playing another draw card of equal or higher value. The penalty adds up and moves to the next player. Example: someone plays +4, you answer with +6, and the next player must answer with +6 or +10, or draw 10 cards and lose their turn.

The Mercy Rule: 25 cards

If you ever hold 25 cards or more, you are eliminated and your cards go back into the discard pile to be reshuffled. This is the rule the game is named after: a couple of stacked penalties are enough to knock someone out.

The 7-0 rule

With 7-0 nobody is safe: the player one card from winning can end up holding fifteen.

The special cards

No Mercy adds cards that don't exist in regular UNO. Each one is explained, with how many are in the deck, in the UNO No Mercy card guide. The short version:

CardWhat it does
Skip EveryoneSkip every opponent and play again.
Discard AllDiscard every card of that color from your hand.
Colored +4A +4 that is not wild: it has to match the color.
Wild Reverse +4Reverses direction and hits the previous player with +4.
Wild +6 and +10The biggest penalties in the deck.
Wild Color RouletteThe next player names a color and draws until it shows up.

Calling out one card

When you are down to one card you have to call it. In Mercy the button is called MERCY: if an opponent is down to one card without calling it and you catch them, they draw 2 cards.

How to win

The first player to empty their hand wins. If the others drop out under the Mercy Rule, the last player left in the game wins.

Optional house rules

In Mercy you pick these when you set up a bot game, or as the host of an online room:
