Pot-Limit Omaha 8 or Better (PLO8) Rules

Pot-Limit Omaha 8 or Better (PLO8) is Omaha Hi-Lo played with a pot-limit betting structure: the pot is split between the best high hand and the best qualifying low, and every bet is capped at the size of the pot. It combines the split-pot mechanics that reward the nut low with the escalating bet sizes of pot-limit poker, which makes position and nut hands even more valuable than in fixed-limit Omaha Hi-Lo.

How PLO8 plays out

Each player is dealt four hole cards. There is a preflop round, then a flop, turn, and river with a betting round after each. At showdown the pot is divided into two halves:

• The high half goes to the best five-card high hand.
• The low half goes to the best qualifying low.

The same player can win both halves — called a scoop — if their hand is best in both directions. If no low qualifies, the high hand takes everything.

The two-card rule from standard Omaha applies to each direction independently. You must use exactly two hole cards plus three board cards for the high, and exactly two hole cards plus three board cards for the low. The two pairs of hole cards you use can be different.

Reading the low

Lows are read from the top card down, and the lowest top card wins. The best possible low is A-2-3-4-5, known as the “wheel,” which also happens to be a straight for the high. Aces play low for the low hand and high for the high hand.

Board (community low cards)	Your best two hole cards	Your low
7♣ 4♥ 3♠ (plus two high cards)	A♦ 2♣	7-4-3-2-A
8♠ 6♦ 5♣	A♥ 2♦	8-6-5-2-A
8♠ 6♦ 5♣	A♥ 4♦	8-6-5-4-A

The first hand is the nut low on that board. Note the third example loses to the second: 8-6-5-4-A is worse than 8-6-5-2-A because the fourth card is higher. Chasing a non-nut low is one of the fastest ways to lose money, a theme we cover in the PLO8 strategy guide.

A few reading rules trip up newcomers:

• The lowest hand wins the low half. Because you compare from the top card down, 8-7-6-5-4 loses to 8-6-5-4-3 — the second card decides it.
• Pairs and cards above eight do not count. If your only two low cards pair the board, or you cannot assemble five distinct ranks eight-or-under, you have no low at all.
• Straights and flushes are ignored for the low. The wheel A-2-3-4-5 is both a straight (for the high) and the best possible low, which is why ace-deuce holdings are so powerful.

The pot-limit betting structure

The “pot-limit” part means the maximum bet or raise is the size of the pot. To find a pot-sized raise, call the current bet, then raise by the new pot total.

This is the key contrast in the “limit Omaha vs pot-limit Omaha” question. Fixed-limit hi-lo uses small, capped bets, so drawing to a non-nut low is cheaper and pots stay small. In PLO8 the pot-sized bets punish weak lows and reward players who make the nuts in both directions. The same starting hand that is a routine call in limit can be a stack-threatening commitment in PLO8, so hand selection tightens considerably as the betting opens up.

Why scooping is everything

Because half the pot can be split away, winning only one direction often means breaking even after the rake. The hands that print money are ones that can scoop — typically an ace-deuce with high-card support, such as A♠ 2♠ K♦ Q♦, which can make the nut low and a strong high.

PLO8 vs regular PLO

Standard Pot-Limit Omaha is a high-only game: the best high hand wins the whole pot. PLO8 adds the low half and the 8-or-better qualifier on top of the same four-card, two-card-rule framework. If you already know the hand order, our poker hand rankings hub covers the high side, and the Omaha Hi-Lo rules page details how highs and lows are read at showdown.

The takeaway

PLO8 rewards patience and nut hands more than almost any Omaha variant: you have to navigate a split pot and pot-sized bets. Play hands that can win both ways, respect the nut-low requirement, and remember the two-card rule cuts both directions.
