UNO Show No Mercy Rules

This page is the rule set the Duetly server enforces for UNO Show No Mercy — based on Mattel’s Show ’Em No Mercy sheet (2–6 players, 168 cards). It is not classic UNO.

Stacking

Draw cards are +2, colored +4, Wild Reverse Draw 4, Wild Draw 6, and Wild Draw 10. You may stack with a Draw card of equal or higher value. Color is ignored during a stack. If you go out with a Draw card, the stack must still resolve before the round ends.

Mercy

Twenty-five or more cards in hand: you are eliminated. Your cards wait to be shuffled back when the draw pile is rebuilt. If you are the only player left, you win.

What we do not include

The later expansion pack (Mercy/No Mercy coins, Wild Final Attack, Sudden Death) is a separate product. Duetly plays the base Show No Mercy deck only.
