Pot-Limit Omaha Rules: How PLO Works
Last updated July 17, 2026 · ~8 min read
Pot-Limit Omaha is the world's second-biggest poker game and the fastest-growing one — because everyone gets more cards, everyone makes more hands, and the action never stops. If you know Texas Hold'em, you can learn PLO in ten minutes. This guide covers the rules, the betting, and the differences between the 4-card, 5-card, and 6-card versions.
The deal: same streets, more cards
A PLO hand runs exactly like a Hold'em hand: blinds are posted, everyone gets hole cards, and there are four betting rounds — preflop, flop, turn, and river — with five community cards. Two things are different:
- You get four hole cards instead of two (five in PLO5, six in PLO6).
- Betting is pot-limit, not no-limit: the most you can bet is the size of the pot.
The rule everyone gets wrong at first
In Omaha you must use exactly two of your hole cards and exactly three board cards to make your five-card hand. Not one, not three — exactly two. This is the single most important rule in the game, and it trips up every Hold'em player at least once:
Board: A♠ K♠ Q♠ J♠ 2♦ ·
Your hand: T♠ 9♥ 8♥ 7♣
In Hold'em you'd have a royal flush using just the T♠. In Omaha you have… a pair
of tens with a straight — you must play two hole cards, and your only spade is one card, not two.
No flush for you.

How pot-limit betting works
"You can bet the pot" sounds simple, but the exact number confuses even experienced players when there's a bet to call. The formula for a maximum raise is:
Max total bet = 3 × the last bet + everything else already in the pot
Three quick examples with $1/$2 blinds:
| Situation | Pot math | Max bet |
|---|---|---|
| You open preflop, first to act | 3 × $2 (big blind) + $1 (small blind) | $7 |
| Someone opened $7, you want to 3-bet | 3 × $7 + $3 (blinds) | $24 |
| Pot is $50 on the flop, first to act | No bet to call — just the pot | $50 |
In practice you just say "pot" and the dealer counts it out — online, there's a pot button. But understanding the math matters strategically: pots grow geometrically. A pot bet triples the pot every street, so a $10 preflop pot can become a $270 river pot with just three pot-sized bets. Stacks go in fast in PLO even without all-in preflop wars.
Why pot-limit instead of no-limit?
With four or more hole cards, hand equities run much closer together than in Hold'em — even aces are rarely a big favorite before the flop. No-limit Omaha would reward mindless preflop shoving. The pot-limit cap keeps early-street bets small relative to stacks, so the interesting decisions happen after the flop, where skill matters most.
PLO4, PLO5, PLO6: the Omaha family
"PLO" by itself traditionally means the 4-card game. The 5-card and 6-card versions follow the exact same rules — same streets, same pot-limit betting, same exactly-two-cards rule — with more hole cards dealt:
| PLO4 | PLO5 | PLO6 | |
|---|---|---|---|
| Hole cards | 4 | 5 | 6 |
| Two-card combos in your hand | 6 | 10 | 15 |
| Average winning hand | Strong | Stronger | Strongest |
| Equities preflop | Close | Closer | Closest |
| Where it's played | Everywhere | Most sites & apps | Apps, some sites |
More combinations mean stronger hands show up more often: in PLO6 a set is often not good by the river, and non-nut flushes are stack-losers. The deeper into the family you go, the more the game becomes about making the nuts — the best possible hand — and the harsher the punishment for second-best. Our PLO5 vs PLO4 comparison covers the strategy shifts in detail, and the PLO6 guide covers the 6-card game.
Five things that surprise Hold'em players
- Everyone has a hand. With 6–15 two-card combos per player, someone usually connects with every flop. Bluffing "air at air" is much rarer than in Hold'em.
- Top pair is nothing. One-pair hands that win pots in Hold'em are usually bluff-catchers at best in Omaha.
- Draws can be favorites. A big wrap (a straight draw with 13–20 outs) plus a flush draw can be a mathematical favorite against a made set. Made hand vs. draw all-ins on the flop are often near coin-flips.
- Aces are not gold. Bare
AAxxwith no suits or connection is a vulnerable hand that plays one street well — preflop. What matters is how all your cards work together. - The nuts change constantly. A hand that's the nuts on the turn can be dead on the river. Reading the board for the current nuts is a core skill — one you can drill with real solver spots in our trainer.
A first strategy, in three lines
Rules in hand, here's the shortest useful strategy primer for any Omaha variant:
- Play hands where all your cards work together — connected, suited, high. Four (or five, or six) random cards are much weaker than they look.
- Draw to the nuts. Second-best flushes and low-end straights are how stacks disappear in this game.
- Respect position. Pots are multiway and stacks go in fast; acting last is worth even more than in Hold'em.
