Omaha hold 'em (also known as Omaha holdem or simply Omaha) is a community card poker game similar to Texas hold 'em, where each player is dealt four cards and must make their best hand using exactly two of them, plus exactly three of the five community cards.

Texas Holdem Poker is the easiest poker game to play but takes time to master. But, a player can spend a lifetime learning the intricacies of Pot-Limit Omaha and still come short because of the complexities and higher variance in the game.

A hand in which a player is guaranteed to at least split the pot with his/her opponent, with a chance to win the pot outright. For example, if you have A&` A&c and your opponent has A&e A&f, and the board comes 8&`9&`2&fQ&`, you're freerolling the ability to win the whole pot with a made flush if a spade hits on the river.

You have many choices to consider when looking at what poker site has the best freerolls. Some of the top choices include places like PokerStars, 888poker, GGPoker, and PartyPoker. You can look around online to see what games are open and what you might be interested in playing the most.
