This game is also known as Omaha High-Low 8 or Better. Omaha High-Low is virtually identical to Omaha High. If you haven’t already done so, you may first want to familiarize yourself with the rules of Omaha High before reading on.

In short, Omaha High and Omaha High-Low are both variants of Texas Holdem that use four Hole cards instead of two. Players then make their best five-card hand(s) out of nine cards (four in the Hole and five on the board) rather than seven (as in Texas Holdem). Also unlike Texas Holdem, players are restricted to using exactly two of their Hole cards, and exactly three of the Community cards to make their five-card hand(s). In Texas Holdem, a player may elect to use only one Hole card and four from the board, or none from the Hole and all from the board: not so in Omaha Poker.
1. Each player is dealt four Hole cards, face down.
2. 1st round of betting.
3. The Flop - Dealer places three shared Community cards face up on the board.
4. 2nd round of betting.
5. The Turn - Dealer place one shared Community cards face up on the board.
6. 3rd round of betting.
7. The River - Dealer places one last shared Community cards face up on the board.
8. 4th round of betting.
9. The Showdown.
At the Showdown in a hand of Omaha High-Low each player makes two different five-card hands, one high and one low, from the four Hole cards and the five Community cards. Again, each player is restricted to using two Hole cards and three Community cards for each of their hands (high and low). However within those limitations players may elect to use all or only some of the same cards to compose their high and low hands.
To qualify as a low hand, no card can be higher than 8, and all five cards must be unpaired. Straights and flushes are not considered when determining low hands, thus the best possible low hand is A,2,3,4,5 regardless of suit.
When the pot is split evenly between two players, one with high hand and one with low, any odd chip leftover goes to the player with the high hand. Identical high hands or identical low hands equally split half of the pot. If the odd chip is between players tied for the highest hand, the player with the highest card (considering rank and suit) gets the chip. If the odd chip is between players tied for lowest hand, the player with the lowest card (considering rank and suit) gets the chip. Suits are ranked highest to lowest as follows; Spades - Hearts - Diamonds - Clubs.
Remember, suits are only considered tiebreakers when a single odd chip is at issue. The rest of the pot is split evenly amongst the tied players regardless of suit.
