Complete Rules & How to Play
Uno No Mercy (officially Uno Show 'Em No Mercy by Mattel) is the ruthless version of the classic Uno card game. With a 168-card deck featuring brutal action cards like +6, +10, Skip Everyone, Discard All, and Reverse Draw Two, this card game takes no prisoners. If you thought Uno was intense, No Mercy cranks it up to 11.
Be the first player to get rid of all your cards. When you play your second-to-last card, you must shout "UNO!". If another player catches you not saying it, you draw 2 cards as a penalty.
In tournament play, points are scored when a player goes out. The first player to reach 1000 points wins the game.
The Uno No Mercy deck (officially Uno Show 'Em No Mercy) contains 168 cards — 60 more than the classic 108-card Uno deck. The deck includes:
To set up:
Uno Show 'Em No Mercy (commonly called Uno No Mercy) plays similarly to classic Uno but with more aggressive cards and official stacking. Play proceeds clockwise. On your turn, you must play a card that matches the color, number, or symbol of the top card on the Discard Pile. Alternatively, you can play a Wild card at any time.
If you cannot play a card, you must draw cards from the Draw Pile until you get a playable card. If you draw a playable card, you may play it immediately. Otherwise, keep drawing until you can play.
In Uno No Mercy, Draw cards can be stacked! When a Draw card is played on you, you can respond by playing a Draw card of equal or higher value to pass the penalty to the next player. The draw amounts accumulate. The player who cannot stack must draw the entire total.
If a player reaches 25 or more cards in their hand at any point, they are immediately knocked out of the game. The player who caused the knockout (by playing the Draw card that pushed them over 25) scores a 250-point knockout bonus.
When you play your second-to-last card, you must shout "UNO!". If another player catches you before the next player takes their turn, you must draw 2 cards as a penalty.
The deck includes number cards from 0 to 9 in four colors: Red, Yellow, Green, and Blue.
Uno No Mercy includes classic action cards plus devastating new ones. All Color Action Cards are worth 20 points each and come in all four colors (Red, Yellow, Green, Blue).
Wild cards can be played on any card regardless of color or number. All Wild Cards are worth 50 points each.
Draw cards (including Wild Draw cards) can be stacked following the rule of equal or higher value. For example, if someone plays a Wild Draw 6 on you, you can respond with another +6 or a +10. The only card that cannot be stacked on top of is the Wild Draw 10. When stacking, the draw penalties accumulate, so the unlucky player who cannot stack may end up drawing 10, 16, or even 20+ cards — potentially triggering the Mercy Rule!
Here is what makes Uno No Mercy different from the original:
When a player goes out, they score points for the cards remaining in opponents' hands:
Each time a player is knocked out via the Mercy Rule (reaching 25+ cards), the player who caused the knockout earns a 250-point bonus.
The first player to reach 1000 points wins the match.
Here are real game scenarios to help you understand how the No Mercy rules work in action:
4 players: Alice, Bob, Charlie, Diana. Play goes clockwise.
Alice plays a Draw Two (+2) (red). Bob stacks a Draw Four (+4) (red). Charlie stacks a Wild Draw 6. Diana has no Draw card to stack...
Diana must draw 2 + 4 + 6 = 12 cards and loses her turn!
3 players: Alice (18 cards), Bob, Charlie.
Bob plays a Wild Draw 10 on Alice. The +10 cannot be stacked. Alice must draw 10 cards, bringing her total to 28 cards.
Alice is knocked out (28 ≥ 25)! Bob earns a 250-point knockout bonus.
Charlie plays a Wild Color Roulette on Diana.
Diana must choose a color. She picks Blue, hoping there are many blue cards. She starts revealing from the Draw Pile: Red 5, Green 3, Yellow Skip, Wild Draw 6 (wilds don't count!), Red 8, Green 2, Yellow 1... finally a Blue 4 appears on the 7th non-wild card.
Diana adds all 8 revealed cards (including the Wild) to her hand and loses her turn. A lucky break — it could have been much worse!
Alice has 12 cards: 5 green cards, a green Discard All, and 6 other cards. Current color is green.
Alice plays the green Discard All. She discards all 5 remaining green cards along with it.
Alice goes from 12 cards to 6 cards in a single play! She's halfway to UNO.
Bob has 9 cards. Alice has just 2 cards and is about to win.
Bob plays a 7 that matches the current color. He chooses to swap hands with Alice.
Bob now has 2 cards (and shouts "UNO!"), while Alice is stuck with Bob's 9 cards. Total reversal!
2 players: Alice and Bob.
Alice plays a Wild Reverse Draw 4. In a 2-player game, the reverse skips Bob... but the +4 penalty comes back to Alice!
Alice draws 4 cards herself! In 2-player mode, this card is a risky move — use it only if you're desperate to change the color.
4 players clockwise: Alice (3 cards), Bob (15 cards), Charlie (8 cards), Diana (2 cards — "UNO!").
Bob plays a 0. All hands rotate clockwise: Alice gets Diana's 2 cards, Bob gets Alice's 3 cards, Charlie gets Bob's 15 cards, Diana gets Charlie's 8 cards.
Bob went from 15 cards to 3. Charlie went from 8 to 15 — dangerously close to the Mercy Rule! Diana lost her UNO position.
Q: Can you stack Draw cards in Uno No Mercy?
A: Yes! Stacking is an official rule in Uno No Mercy. Draw cards (+2, +4, +6, +10) can be stacked with a card of equal or higher value. For example, if a +2 is played on you, you can play a +2, +4, +6, or +10. The amounts accumulate and the player who cannot stack must draw the entire total. The Wild Draw 10 cannot be stacked — the next player must draw all accumulated cards.
Q: What happens if you forget to say Uno?
A: If you play your second-to-last card without saying "UNO!" and another player catches you before the next player takes their turn, you must draw 2 cards as a penalty.
Q: Can you play Discard All on any turn?
A: You can play a Discard All card when its color matches the current Discard Pile color (or the chosen color). When you play it, you also discard ALL other cards in your hand that match that color. This is one of the most powerful moves in the game — strategically, save Discard All for when you have many cards of one color!
Q: How is Uno No Mercy different from regular Uno?
A: Uno No Mercy adds brutal new cards (colored Draw Four, Skip Everyone, Discard All, Wild Reverse Draw 4, Wild Draw 6, Wild Draw 10, Wild Color Roulette), makes stacking official (equal or higher value), uses a larger 168-card deck, introduces the Mercy Rule (25+ cards = knocked out for 250 bonus points), requires drawing until you find a playable card, adds special rules for 7s (hand swap) and 0s (hand rotation), and raises the win target to 1000 points. Much more intense gameplay!
Q: How many cards do you start with in Uno No Mercy?
A: Each player starts with 7 cards, same as classic Uno.
Q: How many cards are in Uno No Mercy?
A: Uno No Mercy (Uno Show 'Em No Mercy) contains 168 cards, compared to 108 in classic Uno. The deck includes number cards (0–9 in four colors with special 7 swap and 0 pass rules), color action cards (Skip, Reverse, Draw Two, Draw Four, Discard All, Skip Everyone), and wild cards (Wild Reverse Draw 4, Wild Draw 6, Wild Draw 10, Wild Color Roulette).
Q: How many people can play Uno No Mercy?
A: Uno No Mercy supports 2 to 10 players. The game works best with 4–6 players for maximum chaos, but it plays well at any count. With more players, the stacking chains and Skip Everyone card become even more impactful.
Q: Can you stack wild cards in Uno No Mercy?
A: Yes! In Uno No Mercy, you can stack Draw cards (including Wild Draw cards) following the rule of equal or higher value. If someone plays a Wild Draw 6 on you, you can respond with another +6 or a +10. The only card that cannot be stacked on top of is the Wild Draw 10. When stacking, draw penalties accumulate — the unlucky player who cannot stack may draw 10, 16, or even 20+ cards, potentially triggering the Mercy Rule (25+ cards = knocked out)!
Q: What does the 0 card do in Uno No Mercy?
A: In Uno No Mercy, when you play a 0 card, all players must pass their entire hand to the next player in the current direction of play. This hand-rotation rule is unique to No Mercy and can completely shake up the game — you might go from having 15 cards to just 2, or vice versa.
Q: What does the 7 with arrows mean in Uno No Mercy?
A: The 7 card with arrows in Uno No Mercy means you must swap your entire hand with another player of your choice. The arrows on the card indicate that hands are being exchanged. This is a powerful strategic tool — you can swap your large hand with someone who has only a few cards left.
Q: What is the Wild Reverse Draw 4 in Uno No Mercy?
A: The Wild Reverse Draw 4 is a Wild card exclusive to Uno No Mercy. It has a double effect: it reverses the direction of play AND forces the next player (in the new direction) to draw 4 cards and lose their turn. In a 2-player game, this card is a bit of a gamble — it skips your opponent but YOU draw 4 cards! As a Wild card, it can be played at any time regardless of the current color.
Q: When did Uno No Mercy come out?
A: Uno Show 'Em No Mercy was released by Mattel in 2023. It quickly became one of the most popular Uno variants due to its aggressive gameplay and viral presence on social media. It is available at major retailers including Amazon, Walmart, and Target.
Q: What is the difference between Uno No Mercy and Uno Flip?
A: Both are Uno variants but they play very differently. Uno Flip features a double-sided deck with a Light Side and a Dark Side — flipping the deck changes the game dramatically. Uno No Mercy focuses on extreme draw penalties (+6, +10), official stacking, and hand-swapping mechanics (0 and 7 cards). No Mercy is generally considered more aggressive, while Flip offers a unique strategic twist with its two-sided cards.
Q: Can you play Uno No Mercy online?
A: As of now, there is no official online version of Uno No Mercy. The standard Uno game is available on platforms like Ubisoft's UNO (PC, console, mobile), but it does not include No Mercy rules. You can play the physical card game in person or use video calls to play remotely with friends.
Q: Is there a challenge rule in Uno No Mercy?
A: Unlike classic Uno, the Draw Four (+4) in Uno No Mercy is a colored action card, not a Wild card. This means there is no challenge rule for the +4 in No Mercy — it is played like any other colored action card by matching the color. The challenge rule only exists in classic Uno for the Wild Draw Four, which can only be played when you have no card matching the current color. See our classic Uno rules for the full challenge rule explanation.
Q: Is Uno Show 'Em No Mercy the same as Uno No Mercy?
A: Yes! Uno Show 'Em No Mercy is the official product name used by Mattel, while Uno No Mercy is the commonly used shorthand. They refer to the exact same card game. You may also see it called "UNO Show Em No Mercy" (without the apostrophe) — it's all the same game with the same 168-card deck and rules.

A: You can view and print a clean version of the complete Uno No Mercy rules on our printable rules page. This print-friendly format is perfect for having a reference sheet during game night — just open the page, press Ctrl+P (or Cmd+P on Mac), and print or save as PDF.
Q: What is the Mercy Rule in Uno No Mercy?
A: The Mercy Rule is a unique rule in Uno Show 'Em No Mercy. If a player reaches 25 or more cards in their hand at any point during the game, they are immediately knocked out. The player who caused the knockout (by playing the Draw card that pushed them over 25) earns a 250-point knockout bonus. This makes stacking chains extremely dangerous and adds real consequences to accumulating too many cards.
Q: What does Wild Color Roulette do in Uno No Mercy?
A: When a Wild Color Roulette is played, the next player must choose a color, then reveal cards from the Draw Pile one at a time until a card of that chosen color appears. Wild cards don't count — they keep drawing. The player adds ALL revealed cards to their hand and loses their turn. This card is pure gambling — you might draw just 1 card or end up with 20+, potentially triggering the Mercy Rule!
