The UNO House Rules card game introduces a dynamic twist to classic UNO gameplay by allowing players to create custom rules during the game. Each rule requires an action, such as "Go moo," "Stand up," or "Touch their nose," with the last player to comply drawing a card. Up to five rules can be active simultaneously. The "Game Changer" card is the sole method for modifying an existing rule. Players must still declare "UNO" when holding one card. This version adds variety to game nights, family gatherings, and social events.
