always A card game is a form of play that uses a deck of cards as the primary tool for gameplay. These cards can be traditional playing cards—like those used in poker or blackjack—or specialized cards created for specific games, such as *Uno* or *Magic: The Gathering*. Card games can involve strategy, chance, skill, or a mix of all three, and their rules vary widely depending on the game. Many card games are played casually for fun, while others are part of serious competitions and tournaments.
