Why it matters

How Omaha odds really work

The two-card rule changes everything: equities run close, draws are huge, and big pairs stop dominating. This calculator uses the real rule, not a Hold'em shortcut.

Omaha equity is not Hold'em equity

In Omaha you hold four cards but must use exactly two of them with exactly three from the board — so the hand you can make is often not the one it looks like. That two-card rule makes equities run much closer than in Hold'em: big pairs are far less dominant, and rundowns and double-suited hands pick up huge equity through wraps and redraws. This calculator applies the real 2-plus-3 rule to every runout, so the numbers are the true Omaha equities, not a Hold'em approximation.

Why the percentages surprise Hold'em players

Aces double-suited against a connected rundown is often only a small favourite — nothing like aces versus a random hand in Hold'em. Draws are monsters: a big wrap plus a flush draw can be the favourite over a made set. Run your spots here, then build the reads with our PLO starting-hand grader and the full Omaha course.

How to use it

How to use the Omaha odds calculator

Four cards each, add the board, read the true equity.

  1. 01

    Give each player four cards

    Tap a card slot and pick from the deck. The tool opens with a double-suited AAKQ against a JT98 rundown so you can see a real Omaha equity straight away.

  2. 02

    Add players or the board

    Compare up to five hands, and set the flop, turn and river to watch equities swing — draws that were ahead can flip on a blank.

  3. 03

    Read the true equity

    Each hand shows its win/tie equity under the exact two-plus-three rule. Flop, turn and river are exact; preflop uses a fast simulation.

FAQ

Omaha odds — common questions

What is the Omaha two-card rule?

In Omaha you are dealt four hole cards and must make your best five-card hand using exactly two of them plus exactly three of the five community cards. You can never play one or three of your hole cards — always exactly two.

Why are Omaha equities so close?

Because every player has six two-card combinations to work with, hands connect with the board far more often. That compresses equities: even aces double-suited are usually only a modest favourite over a good rundown, unlike Hold'em where aces crush.

Are the numbers exact?

On the flop, turn and river the calculator enumerates every remaining runout and evaluates each with the true two-plus-three rule, so they're exact. Preflop it runs a 30,000-hand Monte Carlo simulation, accurate to about ±0.3%.

Does this work for 5-card or 6-card Omaha?

This calculator is for standard four-card Pot-Limit Omaha. The two-plus-three rule and evaluation are specific to the four-card game.

How many hands can I compare?

From two up to five four-card hands at once, plus any board — enough for a full multiway Omaha showdown.
