Omaha Hi poker, usually renowned simply as Omaha, is very similar to Texas Holdem. There are two main differences between the games:

1. In Omaha, instead of receiving only two hole cards, each player receives four.
2. In Omaha, players must use exactly two of their hole cards in combination with three community cards to make their five-card poker hand.

Structurally, Omaha is pretty much the same game as Holdem. Let’s take a look at the rules:

1. A small dealer button identifies one player as the dealer. The dealer button moves clockwise around the table, and is voted for at the end of every hand.
2. All blinds, antes or other required bets must be place into the pot before any cards are dealt. In Omaha.
   1. The player directly to the left of the dealer posts the small blind.
   2. The player two spots to the left of the dealer posts the huge blind.
   3. Generally, the small blind is half the size of the huge blind.
3. After the required bets have been placed, four hole cards are dealt face down to each player. A betting round starts, beginning with the player to the left of the huge blind. This player is said to be ‘under the gun’.
4. Once betting has completed in the first round, three community cards are dealt face up, for all players to use. A second betting round follows the deal, beginning with the player in the small blind. This betting round is renowned as the ‘flop’, or ‘Third Street’.
5. Once betting has completed on the flop, one community card is dealt face up, for all players to use. A third betting round follows the deal, beginning again with the player in the small blind. This betting round is renowned as the ‘turn’, or ‘Fourth Street’.
6. Once betting has completed on the turn, a final community card is dealt face up, for all players to use. A fourth and final betting round follows the deal, beginning once more with the player in the small blind. This betting round is renowned as the ‘river’, or ‘Fifth Street’.
7. Once all betting is complete on the river, any players remaining in the hand must show down their cards. All players subdue involved must compare their five-card poker hands. The pot is handed over to the player with the highest ranked hand.

Omaha Hi-Lo (Omaha 8):

Omaha Hi-Lo, usually renowned as Omaha 8, is structurally the exact same game as Omaha Hi. There is, but, one fundamental difference:

1. In Omaha 8, players can aim to make either the best high poker hand, or the best low poker hand. In the case that one player shows down a winning high hand, and the other shows down a winning low hand, the two players split the pot. In order to win the full pot at showdown, a player must have both the best high and low hand, or there must be no low hand in play.
