Mattel Games UNO Show 'em No Mercy

Massive Card Expansion: Adds 56 brand-new cards to the standard deck, introducing far more chaos and unpredictability to every round.

Brutal Stacking Penalties: Allows players to pass draw penalties (ranging from +2 all the way up to +10) down the line until someone is forced to pick up the entire accumulated stack.

Ruthless Special Cards: Features punishing action cards like Everyone Loses Their Turn, Discard All, and color-swapping Wild Steal Six and Wild Steal 10 cards.

Merciless Elimination Rule: Instantly knocks a player out of the game if they ever accumulate 25 or more cards in their hand at any single time.

The "7" and "0" Rule Modifiers: Incorporating numbers 7 and 0 allows players to swap hands with an opponent or force everyone to pass their hands in a designated direction.

The Mercy Rule: Includes a mercy clause stating that if any single player manages to cross 25 cards, they are automatically eliminated so the game can end before friendships are permanently ruined.
