About the game

What you do in a play session

UNO Show 'Em No Mercy Attack cranks up the classic card game with a two-button card launcher and ruthless rules. Matching colors and numbers is just the start—brace for unpredictable card blasts that can flip the game in seconds. Press the yellow button when you draw, hoping to avoid a flood of cards. The red button, triggered by special cards, charges up a devastating attack to drown opponents in cards. With savage rules and powerful actions, every turn is chaotic fun and tension. Ideal for players aged 7+ who love cutthroat competition.
