Why every PLO hand feels close to every other one
This is the thing that catches players moving over from Hold'em, and it is measurable rather than a matter of opinion. In Hold'em the best starting hand wins 85.1% against a random hand and the worst wins 32.1% — a spread of 53.0 points. In 4-card PLO the same span runs from 68.9% down to 43.2%, a spread of 25.7.
Preflop equity in PLO is spread 2.1 times more tightly than in Hold'em, and it tightens further every time you add a card.
| Game | Distinct hands | Best | Worst | Spread |
|---|---|---|---|---|
| Texas Hold'em | 1,326 | 85.1% | 32.1% | 53.0pp |
| 4-card PLO | 270,725 | 68.9% | 43.2% | 25.7pp |
| 5-card PLO | 2,598,960 | 62.4% | 39.5% | 22.9pp |
| 6-card PLO | 20,358,520 | 62.0% | 41.9% | 20.1pp |
Two things follow, and they explain most of what feels strange about the game. The first is that you cannot win a PLO pot preflop the way you can in Hold'em: with the best hand only 68.9% against one opponent, aces are a small favourite rather than a lock, and against three opponents they are often an underdog. The second is that position and playability matter more than rank, because rank is doing so much less work. A hand that is 43.2% and connected outruns a hand that is a point or two better and disconnected far more often than the same gap would suggest in Hold'em.
It also gets worse as the deck gets wider. 6-card PLO has 20,358,520 distinct starting hands against Hold'em's 1,326, and the spread is down to 20.1 points — the strongest class there is aaxxxx, triple-suited at only 62.0%.

Frequently asked questions
What is the best starting hand in PLO?›
AAxx, double-suited — two aces plus 2 side cards with ranks drawn uniformly and independently from deuce to king. It wins 68.9% against one random hand, all in preflop. That is a long way short of Hold'em, where the best hand wins 85.1%, and it is the single most important difference between the two games: aces in PLO are a favourite, not a lock.
Why do PLO hands have such similar equity?›
Because every player makes their best five-card hand from exactly two hole cards plus three board cards, so four cards give you six two-card combinations to draw from and everyone's range improves at once. Measured against one random hand, Hold'em runs from 85.1% down to 32.1% — a 53.0 point spread — while 4-card PLO runs 68.9% to 43.2%, a spread of 25.7. That is 2.1 times tighter, which is why position and playability matter more than raw rank.
How many starting hands are there in PLO?›
270,725 distinct four-card hands, against 1,326 two-card holdings in Hold'em. 5-card PLO has 2,598,960 and 6-card has 20,358,520. That is why PLO charts group hands into classes rather than listing them: a 13 by 13 grid cannot hold 270,725 hands.
Is 5-card or 6-card PLO different from regular PLO?›
Yes, and in a consistent direction: more cards means flatter equities. The spread between the strongest and weakest class is 25.7 points in 4-card, 22.9 in 5-card and 20.1 in 6-card. The strongest class in 6-card PLO is only 62.0%, so preflop edges shrink and postflop skill carries more of the result. Each has its own calculator on this site.
Do these calculators enforce the two-hole-card rule?›
Yes. Every Omaha calculator here makes the best five-card hand from exactly two hole cards and exactly three board cards, which is the rule that catches Hold'em players — four to a flush on the board does not give you a flush unless two of your own cards are that suit. The same engine runs the 4, 5 and 6-card calculators and Big O.
Where do these equity numbers come from?›
Our own simulation, not a third party. Each hand class was run over 400,000 seeded runouts — 16,400,000 in total, seed 20260917 — against one random hand of the same size, all in preflop with all five board cards dealt. The 95% margin of error is 0.2 percentage points, which is why every figure is quoted to one decimal and no further. Chopped pots count as half.
