Card game variants are different versions of traditional card games that introduce new rules or gameplay mechanics. These variants can change the number of players, the objective of the game, or the way cards are played. For example, the classic game of Poker has many variants, such as Texas Hold'em and Omaha, each with unique rules and strategies. Players often create variants to add variety and excitement to familiar games. Some popular card games, like Rummy and Solitaire, also have numerous variants that cater to different skill levels and preferences. These adaptations can enhance social interaction and keep the gameplay fresh and engaging.
