The Story

Liar's UNO, released by Mattel in 2025, builds bluffing directly into the core loop: over half the deck consists of "Liar's Cards" — a face-down counterpart to almost every regular card — which a player plays face-down while announcing what it supposedly is. Opponents can call the bluff; guess wrong and the accuser draws a card, guess right and the liar draws instead. The deck also carries ColorADD-style symbols so colorblind players can join in.

Rule Twists vs. Classic UNO

Everything below is an official printed rule unless flagged otherwise.

Liar's Cards

Over half the deck consists of Liar's Cards — a hidden counterpart to most regular cards. Playing one face-down requires the player to announce what it is, truthfully or not.

Challenging a Liar

Any player may challenge a face-down Liar's Card. If the claim was false, the liar draws a card; if it was actually true, the challenger draws instead.

0's Pass

Playing a 0 card of any color forces every player to pass their entire hand to the next player in the current direction of play.

Special Cards & Action Rules

The next player draws four cards and loses their turn; the player who played it names the next color.
