Everything you need to know about Omaha Hi-Lo (O8), from split-pot mechanics and the 8-or-better qualifying rule to starting hands, scoop strategy, and the most common mistakes players make.
Omaha Hi-Lo — also known as Omaha 8-or-Better (O8) or PLO8 — is a split-pot variant of Pot-Limit Omaha. Like standard PLO, every player receives four hole cards and must use exactly two of them combined with exactly three of the five community cards to form the best possible five-card hand.
The twist is that the pot is split between two winners: the player with the best high hand and the player with the best qualifying low hand. If no qualifying low hand exists, the high hand scoops (takes) the entire pot. This dual-pot dynamic creates a game rich in strategic depth, where the most profitable plays are those that give you a shot at winning both halves.
Omaha Hi-Lo is commonly spread in limit format at cardrooms, though pot-limit versions (PLO8) are increasingly popular online. The betting structure follows the same streets as regular Omaha: preflop, flop, turn, and river. The only difference is how the pot is awarded at showdown.
At showdown the pot is divided into two equal halves. The best high hand takes one half, and the best qualifying low hand takes the other. Here is how each side works:
High Hand
Standard poker hand rankings apply. The best five-card combination using exactly two hole cards and three board cards wins. Royal flush is the best, high card the worst — same as Hold'em hand rankings.
Low Hand
Must consist of five unpaired cards all ranked 8 or below. Aces count as low. The best possible low is A-2-3-4-5, known as "the wheel." Straights and flushes do not count against a low hand.
Key Split-Pot Rules
Example: You hold A♥ 2♠ K♥ Q♠ and the board reads 3♥ 5♥ 7♣ J♥ K♣. For the high, you use K♥ Q♠ with the board's K♣ to make a pair of kings with a queen kicker. For the low, you use A♥ 2♠ combined with the board's 3-5-7 to make A-2-3-5-7 — a very strong qualifying low. You could potentially win both halves of the pot.
The "8-or-better" part of the name refers to the qualifying rule for low hands. For a low hand to be eligible to win half the pot, it must meet specific requirements:
Qualifying Boards
Non-Qualifying Boards
Low hands are compared from the highest card down. An 8-6-4-3-A low loses to a 7-5-4-3-2 low because 8 is higher than 7 in the first comparison. The best possible low — A-2-3-4-5 (the wheel) — also doubles as a five-high straight on the high side, making it one of the most powerful holdings in Omaha Hi-Lo.
In Omaha Hi-Lo the most valuable hands are those that can compete for both the high and the low simultaneously. Having an A-2 in your hand is the single most important holding because it gives you the nut low draw. Combine that with high cards, pairs, or suited cards and you have a premium starting hand. The abbreviation "ds" means double-suited (two cards of each suit).
| Hand | Strength | Why It Works |
|---|---|---|
| A-2-3-K (ds) | Tier 1 | Nut low draw + nut high potential, double suited |
| A-A-2-3 (ds) | Tier 1 | Premium pair + nut low draw, double suited |
| A-2-4-5 (ds) | Tier 1 | Two-way nut low draw + wheel straight potential |
| A-A-2-x (suited) | Tier 1 | Aces for high + nut low draw with backup |
| A-2-K-K (suited) | Tier 2 | Strong high pair + nut low draw |
| A-2-3-4 (suited) | Tier 2 | Triple low backup, strong wheel potential |
| A-3-4-5 (suited) | Tier 2 | Second-nut low draw + wheel wraps |
| A-2-Q-Q (suited) | Tier 2 | Queens for high + nut low draw |
| A-2-K-Q (suited) | Tier 3 | Broadway high cards + nut low draw |
| A-2-J-T (suited) | Tier 3 | Nut low draw + connected high cards |
Hands without an A-2 or A-3 are significantly weaker in Hi-Lo because they cannot make the nut low. For more on Omaha hand selection, see our Omaha strategy guide.
Omaha Hi-Lo rewards disciplined hand selection and patience more than almost any other poker variant. These eight principles will give you a significant edge over most recreational opponents.
The biggest pots go to players who win both the high and the low. Always prefer hands that have a realistic path to scooping over hands that can only compete for one side. Winning half the pot is break-even at best after rake.
Holding A-2 gives you the nut low draw. If three low cards hit the board, you will have the best possible low (or close to it). The nut low draw is so valuable that many experienced players will not enter a pot without it.
Quartering happens when you split the low half with another player while a third player takes the entire high half. You invested chips to compete for a full pot but end up with only a quarter. Be cautious when multiple opponents likely share your low draw.
If you win the low, you only win half the pot. After subtracting the chips you put in, a low-only hand is rarely profitable. Add a high draw (flush, straight, two pair) to your low draw and your hand becomes significantly more valuable.
A suited ace with low cards gives you the nut flush draw for high and a low draw for the other half. These combo draws are the bread and butter of winning Hi-Lo players because they have realistic scoop potential on many board textures.
Making A-2-3-4-5 wins the nut low and simultaneously makes a five-high straight for high. On boards without a flush, the wheel frequently scoops the entire pot. Hands with A-2-3, A-2-4, or A-3-4-5 all have wheel potential.
Acting last lets you see whether a low is possible before committing chips. If the board shows only high cards on the flop, you can play your high hand aggressively knowing no one can take half the pot. In early position, you are guessing.
If you hold A-2 and the board shows 3-5-7, you have the nut low (A-2-3-5-7). But if a 2 hits the turn, your low is counterfeited because now you would need to use the board 2 and your A, giving you A-2-3-5-7 at best — but other players with A-4 now beat you. Having a backup low card (A-2-3-x) protects against this.
If you already play Pot-Limit Omaha or PLO5, transitioning to Hi-Lo requires a significant shift in hand selection and strategy. This table highlights the most important differences.
| Aspect | Omaha Hi-Lo | Regular PLO |
|---|---|---|
| Pot structure | Split between high and low | Entire pot to best hand |
| Hand selection | Favor hands that can scoop both ways | Favor connected, suited, paired hands |
| Importance of A-2 | Critical (nut low draw) | Weak holding (poor connectivity) |
| Scooping | Primary goal, wins the full pot | Every pot is a scoop by default |
| Variance | Lower (split pots reduce swings) | Higher (winner-take-all pots) |
| Bluffing frequency | Lower (split pots reduce fold equity) | Higher (full pot at stake) |
| Post-flop complexity | Very high (tracking high AND low draws) | High (tracking high draws only) |
The biggest adjustment for PLO players is recognizing that A-2 suited — a weak hand in regular Omaha — becomes one of the strongest holdings in Hi-Lo. Hands like K-Q-J-T double-suited, which dominate PLO, lose considerable value in O8 because they have zero low potential.
Even experienced Omaha players fall into these traps when they first sit down at a Hi-Lo table. Recognizing and avoiding these mistakes will immediately improve your results.
Chasing only the low half means the best you can do is win 50% of the pot. After rake and the chips you invested, low-only hands are marginal at best. You need high potential too — a flush draw, a straight draw, or a strong pair — to make the hand worth playing.
Your nut low can be destroyed (counterfeited) when the board pairs one of your low cards. If you hold A-2 and a deuce hits the board, your previously dominant low is now mediocre or dead. Always value hands with backup low cards like A-2-3 over naked A-2 holdings.
Big pairs (K-K-x-x, Q-Q-x-x) without low cards are significantly weaker in Hi-Lo than in regular PLO. When a low is possible, the best you can win is half the pot. And when no low is possible, multiple opponents are also likely to have high-only hands, creating more competition.
When two players split the low and one player takes the high, the low players each receive just 25% of the pot. If you put in a third of the money but only win a quarter of the pot, you are losing money. Be especially careful in multi-way pots where other players likely share your A-2 low draw.
Omaha Hi-Lo is just one of several exciting Omaha variants. Deepen your understanding of split-pot strategy, explore standard PLO, or test your skills with our free tools.
Omaha Hi-Lo (8-or-Better) is one of the most strategically rewarding poker variants you can play. The split-pot format rewards patience, hand reading, and disciplined starting hand selection far more than aggression alone. Players who understand the qualifying low rules, prioritize scoop potential, and protect against counterfeiting consistently outperform those who treat it like standard Omaha.
