Omaha Hi is a game where players try to make the highest possible five-card hand by using four personal and five community cards. Each hand must contain two personal and three community cards. Each player is given four cards and there is a round for betting. The flop is when three community cards are placed face-up on the table. This ends the round of betting. There are additional betting rounds after the turn, river and the turn. The winner has the best hand using two personal cards and three community cards. Hi-Lo is a game where the player with the best hand splits the pot.

Omaha poker can be played by up to ten players. Each player receives four cards from the dealer. After four rounds worth of betting, each player is dealt four cards face-down. Five community cards are then placed face-up at the table. They are shared equally by all players. To make the best poker hand, the player can combine any two (or more) of the four cards in their hand with the community card.

A-2-3-4-5 is the lowest Razz hand. Straights and flushes do not count against a low hand, and aces count for low cards. The 'Ace to 5 straight' is also known as, "the bike" or "the wheel," and is thus the best possible low hand.

After the betting has ended, the three community cards will be dealt to everyone. In poker terminology, this is called the "flop". The situation can now be adjusted by the players and a new round of betting card poker begins. If no one places a bet then players have the option to check, fold or bet. Players can call, raise, or fold a bet that has been placed.

BET: A player may bet if there's no wager on this betting round. If a player wagers, the poker players immediately clockwise from them (and any other poker players) can fold, raise or call.

The main difference with Omaha and Texas Holdem is that Omaha poker requires you to deal four cards at the start of each game, rather than just two. However you are only permitted to use two of the four cards plus any three of the five community cards.

Each player now combines the two cards that they have with the three available at the table to make their own five-card poker hands. The next round of betting begins with the small blind and bets continue around to the player on the dealer button.

Joseph Crowell (an English actor) wrote about the game in New Orleans in 1829. The game was played with a 20-card deck. Slot Online had four players who bet the most on which player's hand would win. The book An Exposure of the Arts and Miseries of Gambling published in 1843 describes how the game spread from New Orleans to the rest of North America via the Mississippi riverboats where gambling was widespread. This helped it to spread west and up the Mississippi River, especially during the golden age. It is believed to have been part of the frontier pioneering culture.
