The deck is the brutal one. Draw cards stack into piles you either match or eat, Wild Draw 6 and Wild Draw 10 slam the table, playing a 7 swaps your entire hand with an opponent and a 0 passes everyone's hand around. Hold 25 cards and the mercy rule eliminates you on the spot, so every stacked draw pile is a threat. Last player standing takes the hand, and first to 1,000 points wins the match.

How to Play

UNO Show 'Em No Mercy — online edition

60-second version

Match the top card by colour, number or symbol. No match? Draw until you find a playable card, then play it.
15 seconds per turn — if you stall, the game plays for you.
Down to your last card? Hit UNO! before you play it, or opponents can CATCH you for +2 cards.
Reach 25 cards and you are eliminated — spectator for the rest of the hand.
Empty your hand to win the hand. First to 1000 points wins the match.

1 Goal & Setup

Two ways to win a hand: be first to get rid of all your cards, or be the last player standing.
Each player starts with 7 cards.
Top card of the Draw Pile is flipped to start the Discard Pile (Action/Wild cards are set aside and another is flipped).
Play moves clockwise from the player on the dealer's left.
Run out of Draw Pile cards? The Discard Pile is shuffled back in — together with any hands set aside by eliminated players.
Scoring: numbers = face value, coloured action cards = 20, wilds = 50, plus 250 bonus points for every player you knock out. Winner of the hand collects it all — first to 1000 wins the match.

2 Your Turn

Play a card matching the colour, number or symbol of the top card. Wilds always match.
No playable card? Click the Draw Pile — No Mercy makes you draw until you get a playable card, then play it right away.
Against a draw stack? Play a draw card of equal or higher value to stack it back, or take the whole stack.
A white timer ring counts down your 15 seconds. Run out and the game auto-draws and plays for you.
A colour-picker appears whenever you play a Wild.

3 UNO & the CATCH Window

When you get down to 2 cards, the UNO! button lights up — press it while it is still your turn (before playing down to 1 card). Your call is locked in and nobody can catch you.
Forget to yell UNO? A 10-second CATCH window opens: every opponent gets a flashing CATCH UNO button.
Caught = you take +2 cards immediately and lose your UNO status.
Nobody catches you within the 10 seconds? The +2 is applied automatically at the end of the window. Forgetting is never free.
Can still yell UNO during your own open window to save yourself (the window closes).
Your UNO call is void if your hand changes after calling — drawing, a 7-swap or a 0-pass all reset it.

Tip: watch opponents with 1 card who didn't call UNO — the CATCH button is your free +2.

4 The 4 No Mercy Rules

Stacking

If someone plays a draw card (+2, +4, +6, +10), the next player may "stack" by playing a draw card of equal or higher value. The stack grows until someone can't — that player draws the combined total and loses their turn.

Mercy Rule

Ever hold 25 or more cards? You are eliminated on the spot — your hand is set aside and you spectate for the rest of the hand (no cards shown, you can still watch the table and voice chat).

Your set-aside hand returns to the Draw Pile the next time it runs out and is reshuffled, so those cards come back into play against everyone still in the game.

7's Swap

Playing any 7 forces you to swap your entire hand with one opponent of your choice. Use it to escape a monster hand — or to bury someone else.

0's Pass

Playing any 0 makes everyone pass their whole hand to the next player in the current direction of play.

5 Action Cards

Draw Two (+2)	The next player draws 2 and loses their turn (stackable).
Draw Four (+4)	The next player draws 4 and loses their turn (stackable).
Skip	The next player is skipped.
Reverse	Direction of play reverses.
Discard All	Throw away every card in your hand that matches this card's colour.
Skip Everyone	Skip all the other players and take another turn.

6 Wild Cards

Wild	Choose the next colour.
Wild Draw 4	Choose colour; next player draws 4 and is skipped.
Wild Draw 6	Next player draws 6 and is skipped.
Wild Draw 10	Next player draws 10 and is skipped.
Wild Reverse Draw 4	Reverse the direction, then the next player in the new direction draws 4 and is skipped (stackable).
Wild Colour Roulette	Next player calls a colour, then reveals cards one at a time from the Draw Pile until they hit that colour — they keep all of them (wilds don't count) and lose their turn.

7 Good to Know
