Poker variants are different versions of the classic card game poker, each with its own unique rules and gameplay. Some popular variants include Texas Hold'em, where players use two private cards and five community cards, and Omaha, which involves four private cards and also five community cards. These variations can change the strategy and excitement of the game, appealing to different types of players. Another interesting variant is Seven Card Stud, which does not use community cards and requires players to make the best hand from their own seven cards. Each variant offers a fresh challenge, allowing players to explore new strategies and enjoy diverse experiences while playing poker.
