Omaha is a poker game like Texas Hold’em, but each player gets four private cards instead of two, and must use exactly two of them plus exactly three of the five community cards to make a hand. It is usually played pot-limit. The best five-card hand at showdown wins the pot, unless the game is Omaha Hi-Lo, where the pot is split between the best high hand and the best qualifying low.
If you know Hold’em, the “exactly two” rule is the only big change, and it is the one that catches beginners out. This guide explains the rules, the betting structure, the hi-lo variant, and the exact card maths that makes Omaha play so differently.
How do you play Omaha: what is the goal?
The goal is to win the pot, either by holding the best hand at showdown or by making every other player fold. Each player receives four hole cards, and five community cards are dealt face up in the middle. Your hand is the best five cards you can make using exactly two of your hole cards and exactly three from the board.
Pagat states this rule directly: players must use exactly two private cards together with three community cards, and must show all their hole cards to be eligible to win. A full house on the board, for example, does not play by itself unless you hold two cards that fit with three of the board.
Hand rankings are the same as in Hold’em. If you need a refresher, see our guide to poker hand rankings.
How does a hand of Omaha play out?
A hand has four betting rounds, just like Hold’em. Pagat lists them as preflop, flop, turn and river.
- Blinds. Two players post forced bets, the small blind and the big blind, to start the pot.
- Deal. Each player gets four face-down hole cards.
- Preflop betting. Starting left of the big blind, each player can fold, call or raise.
- Flop. Three community cards are dealt, followed by a betting round.
- Turn. A fourth community card, then betting.
- River. A fifth community card, then the last betting round.
- Showdown. Remaining players show all four hole cards, and the best five-card hand using exactly two of them wins.
The dealer button moves one seat clockwise after each hand. The structure matches Texas Hold’em, so the same table layout and blinds apply.
What does pot-limit mean in Omaha?
Omaha is usually played pot-limit, abbreviated PLO. In pot-limit, the largest bet or raise you can make is the current size of the pot. That caps the action more than no-limit Hold’em, where you can bet everything at any time.
Pot-limit raise sizing has a standard method. To find the biggest raise, you add up the pot, including the bet you are facing, and then add the amount you must call. For example, if the pot is 100 and your opponent bets 100, the pot is now 200. You call 100 and then raise by 300 (the size of the pot after your call), so the total raise is to 400. Most online sites and live dealers calculate this for you, but it helps to know where the number comes from.
Other limits exist. Pagat notes that Omaha is “usually” pot-limit but that other limits are possible, and Omaha Hi-Lo is often fixed-limit.
What is the exactly-two rule, and why does it matter?
The exactly-two rule means your four hole cards never all count, and the board never plays alone. It changes which hands are strong and which hands are traps. Look at two common situations:
- Flush on the board: there are four spades on the board and you hold one spade. In Hold’em that is a flush. In Omaha you need two spades in your hand, so one spade is not enough.
- Straight on the board: 5-6-7-8-9 on the board gives everyone a straight in Hold’em. In Omaha you must use two of your own cards with exactly three board cards, so the board straight does not play on its own.
This is why Omaha players talk so much about “the nuts,” the best possible hand on a given board. A good-looking second-best hand can lose a lot of money against it.
How is Omaha different from Texas Hold’em in numbers?
Omaha has far more starting hands and far more ways to make a hand. Card Player lists Hold’em with 169 unique starting hand types against Omaha’s 16,432. We checked the underlying counts ourselves.
| Measure | Texas Hold’em | Omaha |
|---|---|---|
| Hole cards | 2 | 4 |
| Possible starting hands | 1,326 | 270,725 |
| Hand choices at showdown | 21 | 60 |
| Hand contains at least one pair | 5.88% | 32.39% |
| Cards used from your hand | 0, 1 or 2 | Exactly 2 |
Three things follow from the table:
- You are dealt a pair far more often. A Hold’em pocket pair arrives 5.88% of the time. At least one pair in an Omaha hand arrives 32.4% of the time (that is one minus 715 times 256 over 270,725), so a pair alone is no longer special.
- More ways to make a hand. With 60 combinations per player at showdown against 21 in Hold’em, each player has many more routes to a strong hand.
- Double-suited hands are common. About 13.5% of hands are two suits of two cards each (36,504 of 270,725), which gives two ways to hit a flush.
What is Omaha Hi-Lo?
Omaha Hi-Lo, often called Omaha eight-or-better, splits the pot between the best high hand and the best low hand. Pagat explains that each player makes a high hand and a low hand, each using exactly two hole cards and three board cards.
A low hand needs five different ranks with none above 8, aces count low, and straights and flushes do not count against it. The best low is A-2-3-4-5. If no player has a qualifying low, the high hand wins the whole pot. Pagat adds that this game is often fixed-limit, with bets doubling after the turn.
Because a single player can win both halves, the aim in Hi-Lo is to “scoop” the pot, and hands with an ace and a 2 are valued for that reason.
What does an Omaha showdown look like?
Say you hold A of spades, K of spades, 9 of hearts and 9 of clubs. The board is Q of spades, J of spades, 4 of spades, 9 of diamonds and 2 of hearts. You use A and K of spades from your hand with the Q, J and 4 of spades from the board. That gives you five spades, an ace-high flush.
Now suppose an opponent holds the 10 of spades, the 8 of clubs, the 3 of diamonds and the 7 of hearts. They have only one spade, so they cannot use the board flush at all. Without two matching hole cards they cannot play it. You also hold a set of nines from your two 9s plus the board 9, but you must pick exactly two hole cards, so you choose between the flush and the set, and the flush is higher. This is the discipline Omaha asks for at every showdown: name the two cards before you claim the pot.
What are common Omaha mistakes?
Most losses in Omaha come from playing hands as if they were Hold’em. The usual ones:
- Counting the board by itself. Remember you need exactly two of your own cards.
- Playing too many hands. With 270,725 starting hands, most are weak, and four cards that do not work together are common.
- Overvaluing one pair. One pair is a weak hand against four-card ranges.
- Chasing the second-best flush or straight. The best draw wins, and the next-best is expensive.
- Misreading pot-limit raises. A raise can be much bigger than it looks.
What does Omaha cost to play?
A private Omaha game has no house edge, so total winnings equal total losses among the players. In a casino or online room, the operator takes a rake from the pots or charges time fees, and that is the cost on top of your own losses. Because pots are larger and swings are bigger in pot-limit, the amount that moves in a session can be large.

What should you learn next?
Practice reading the best possible hand on a board while holding four cards, and force yourself to name the two cards you would use. When that feels natural, learn the general rules in our poker guide, and compare Omaha with the casino table games blackjack and baccarat, which have a fixed house edge and no opponent to outplay.
