Popular poker games include Texas Hold'em, Omaha, Seven-Card Stud, and Pineapple. Texas Hold'em is the most widely played variant, known for its strategic depth and community cards. Omaha offers a twist with four hole cards, increasing the action and potential hands. Seven-Card Stud, once the dominant form, features no community cards and requires players to make the best hand from their own cards. Pineapple, a fun variant, allows players to discard one of their three hole cards after the flop. Each game offers unique strategies and challenges, appealing to both casual players and seasoned pros.
