What is the meaning of Mattel Uno Flip cards and how do they differ from traditional Uno cards?

Mattel Uno Flip cards are a variation of the traditional Uno card game that introduces a new set of cards with a different design and gameplay mechanics. The main difference between Uno Flip cards and traditional Uno cards is that Uno Flip cards have a "dark side" and a "light side," each with its own set of rules and challenges. Players can choose to flip the deck at any time during the game, changing the dynamics and strategies involved. This adds a new layer of complexity and excitement to the classic Uno experience.
