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 composition includes:

• Number cards (0–9) in four colors — 1× each 0, 2× each 1–9 per color (76 cards)
• Action cards — Skip, Reverse, Draw Two (2× each per color = 24 cards), plus Skip Everyone, Reverse Draw Two, Discard All (2× each per color = 24 cards)
• Wild cards — Wild (4), Wild Draw Four (4), Wild Draw Six (4), Wild Draw Ten (4) = 16 cards

To set up:

1. Shuffle the entire 168-card deck thoroughly.
2. Deal 7 cards to each player.
3. Place the remaining deck face down to form the draw pile.
4. Flip the top card of the draw pile to start the discard pile.
5. If the first card is an action card, its effect applies immediately.

The standard Uno deck has 108 cards:

1. Shuffle the deck and deal 7 cards to each player.
2. Place the rest face down as the draw pile.
3. Flip the top card to start the discard pile.

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 one card from the draw pile. If the drawn card can be played, you may play it immediately. Otherwise, your turn ends.

Stacking Rules

In Uno No Mercy, Draw cards can be stacked! If a +2 is played on you, you can play another +2 (or a +4, +6, or +10) to pass the penalty to the next player. The draw amounts accumulate. The player who cannot stack must draw the entire total.

• +2 can be stacked with +2, +4, +6, or +10
• +4 can be stacked with +4, +6, or +10
• +6 can be stacked with +6 or +10
• +10 cannot be stacked — the next player must draw

Challenge Rule (Wild Draw Four)

If you suspect a player illegally played a Wild Draw Four (meaning they did have a card matching the current color), you can challenge them. The challenged player must show their hand privately. If the challenge is successful (they did have a matching card), the player who played the Wild +4 draws 4 cards instead. If the challenge fails, the challenger draws 6 cards total (4 + 2 penalty).

On your turn, play a card that matches the top of the discard pile by color, number, or symbol. You can also play a Wild card at any time.

If you can't play, draw one card. If it's playable, you may play it immediately.

When you have one card left, shout "UNO!" If caught not saying it, draw 2 cards.

The deck includes number cards from 0 to 9 in four colors: Red, Yellow, Green, and Blue.

• Each color has one 0 card and two of each number 1-9.
• Number cards have no special effect — simply match by color or number.

Uno No Mercy includes all classic action cards plus devastating new ones. Here is the complete list of action card meanings:

Classic Action Cards

• Skip — The next player loses their turn.
• Reverse — Reverses the direction of play. In a 2-player game, acts as a Skip.
• Draw Two (+2) — The next player must draw 2 cards and lose their turn (unless they can stack).

No Mercy Exclusive Action Cards

• Skip Everyone — Every other player is skipped. You get another turn immediately! This is one of the most powerful action cards in the game.
• Reverse Draw Two — Reverses play direction AND the next player draws 2 cards. A brutal two-in-one combo card.
• Discard All — Discard ALL cards in your hand that match the current color. This can dramatically reduce your hand size in one play! Strategically, save this card for when you have many cards of one color.

Special Number Card Rules

• 0 Card — When you play a 0, all players must pass their hand to the next player in the current direction of play. This hand-swapping mechanic can completely change the game!
• 7 Card (with arrows) — When you play a 7, you choose one other player and swap your entire hand with them. The arrows on the card remind you that hands are being exchanged.

Wild cards can be played on any card regardless of color or number. Here are all the wild card meanings in Uno No Mercy:

• Wild — Choose the color that continues play. Can be played at any time on your turn.
• Wild Draw Four (+4) — Choose the color AND the next player draws 4 cards. Can only be legally played if you have no cards matching the current color. Other players may challenge this play (see Challenge Rule above). This card can be stacked — if someone plays a +4 on you, you can play your own +4, +6, or +10.
• Wild Draw Six (+6) — Choose the color AND the next player draws 6 cards. A devastating No Mercy exclusive! Can be stacked with another +6 or a +10.
• Wild Draw Ten (+10) — The ultimate punishment. Choose the color AND the next player draws 10 cards. Cannot be stacked — there is no defense against this card. This is the nuclear option of Uno No Mercy.

Can You Stack Wild Cards?

Yes! Wild Draw cards can be stacked following the stacking hierarchy: +4 → +4/+6/+10, and +6 → +6/+10. The only card that cannot be stacked on top of is the Wild Draw Ten (+10). When stacking, the draw penalties accumulate, so the unlucky player who cannot stack may end up drawing 10, 16, or even 20+ cards.

Here is what makes Uno No Mercy different from the original:

• Stacking is official — Draw cards can be stacked, unlike classic Uno official rules.
• New brutal cards — +6, +10, Skip Everyone, Discard All, and Reverse Draw Two are all new.
• Larger deck — 168 cards vs. 108 in classic Uno.
• Faster elimination — With Discard All, games can end much faster.
• Higher stakes — Draw penalties can reach 20+ cards with stacking.

When a player goes out, they score points for the cards remaining in opponents' hands:

• Number cards (0-9) — Face value
• Skip, Reverse, Draw Two — 20 points each
• Skip Everyone, Reverse Draw Two, Discard All — 30 points each
• Wild, Wild +4 — 40 points each
• Wild +6 — 50 points each
• Wild +10 — 60 points each

First player to 500 points wins the match.

When someone goes out, score the remaining cards in opponents' hands:

• Number cards: face value
• Skip / Reverse / Draw Two: 20 points
• Wild / Wild Draw Four: 50 points

• Skip — Next player loses their turn.
• Reverse — Changes direction of play.
• Draw Two (+2) — Next player draws 2 and loses their turn.
• Wild — Play on anything; choose the next color.
• Wild Draw Four — Choose color; next player draws 4. Can only be played when you have no matching color cards.
