Poker Variant is a term used to describe different types of poker games. Two of the most popular variants are Omaha and Holdem. Omaha is a community card game where each player is dealt four cards and must make their best five-card hand using two of their own cards and three of the five community cards. Holdem is also a community card game, but each player is dealt two cards and must make their best five-card hand using any combination of their two cards and the five community cards.
