Pick cards to see live equity
In 5-card PLO you hold five cards and still use exactly two, so every hand contains ten two-card combos instead of PLO4's six. That compresses equity across the board: the top hand class - double-suited aces with connected middle cards, A-A-T-9-9 being typical - wins about 65% against one random hand, where PLO4's best (A-A-T-T double-suited) wins 71.5%. Big pairs also arrive more often; you hold at least two aces 4.17% of deals, vs 2.57% in PLO4. This calculator computes PLO5 equity for two to six hands. Enter hole cards, optionally a flop, turn or river plus dead cards: postflop it enumerates every remaining runout for an exact answer, and preflop it runs Monte Carlo until every hand converges to a ±0.3% target. The percentile readout under each complete hand comes from the same tables behind the PLO5 starting hand rankings.

How it works
Pick cards for two to six PLO5 hands and watch equity update live. Results are exact on the flop, turn and river; preflop is exact when few enough runouts remain, Monte Carlo to a ±0.3% target otherwise. Add a board, mark dead cards, lock hands you want to keep, and share any spot with a link.
What are the best PLO5 starting hands?
The top of the table is a 142-way statistical tie at 65.1-65.6% equity against one random hand. The profile is consistent: every member holds two aces, 90% are double-suited, and the side cards cluster on T-8-9-J. A-A-T-9-9, A-A-T-T-9 and A-A-T-9-8 double-suited are typical members. The full list, all 134,459 hand classes, is on our PLO5 starting hand rankings page with a downloadable CSV.
How much closer do PLO5 equities run than PLO4?
Aces vs kings, both double-suited, is about 70/30 in PLO4 and 63/37 in PLO5. The mechanism is the extra card: ten two-card combos per hand instead of six, so the underdog finds more boards. Preflop edges shrink, and playability and nut potential carry more of a hand's value. When a matchup looks closer than your PLO4 instinct says, the number is right and the instinct is off.
How often are you dealt aces in PLO5?
You hold at least two aces 4.17% of the time in PLO5, vs 2.57% in PLO4 and 6.08% in PLO6 - exact combinatorics, not simulation. Five-card aces are rarely bare aces, though: the three side cards decide whether you have a premium (suits, connection) or a hand that plays like a trap.
Is PLO5 the same as Big O?
Same five-card deal, usually a different game. Live Big O is normally 5-card Omaha hi-lo with eight-or-better split pots; online PLO5 usually means high-only, which is what this page computes. For split-pot equity with scoop and quarter rates, pick Big O in the game selector above, or press L. Same calculator, same page; switching scoring clears the slots, so re-enter the five cards and compare the two numbers.
Does the rule of 2 and 4 work in PLO5?
It overstates equity even worse than in PLO4. PLO5 wraps run to 20 outs and beyond, but outs overlap with opponents' redraws, some outs make second-best hands, and multiway pots are standard. The shortcut prices a 20-out wrap at 80%; against a set with redraws the true number lands near half that. Count outs as a rough floor-check, then get the exact number here.
Are the results exact or simulated?
Flop, turn and river: exact, every runout enumerated. Preflop depends on the spot: six-way PLO5 leaves 26,334 possible boards and enumerates outright, while heads-up preflop leaves 850,668 and runs Monte Carlo until every hand's 95% interval is inside ±0.3%. The status line under the equity bar reports which mode ran, with the runout count.
Can I lock a hand and deal random opponents?
Yes. Complete a hand, click its lock icon, then press R (or Randomize): locked hands keep their cards and everything else is redealt from the remaining deck. That is the fastest way to see how a hand runs against N random hands - equity vs one random hand is exactly what the rankings tables measure, so you can sanity-check a ranking live.
