How to use the Omaha calculator
Enter four cards per player, or leave a seat empty to compare against a random hand. Add the flop, turn and river as they come. From the flop on, the result is exact: every remaining turn and river combination is enumerated. Preflop uses Monte Carlo sampling; press “More precision” if you want the margin under ±0.1%.
The same engine powers the 5-card and 6-card variants: 5-Card Omaha and 6-Card Omaha. Set the game with the g parameter in a shared link, or use the quick input to paste hands such as AhAdKhKd JsTs9c8c / 7s6s2d.
What makes Omaha odds different
The two-from-hand, three-from-board rule is where most new PLO players lose money. With A♥ in hand and four hearts on board you do not have a flush; with A♥K♥ you do, and the calculator enforces this automatically. Equities also run much closer preflop: the best starting hand, A♠A♥K♠K♥, is a 3:2 favourite at best against a good rundown, big pairs are worth far less than in Hold’em, and connected, double-suited hands are worth far more. Draws get enormous, too. Wraps with 13, 17 or 20 outs are common, and a flush draw plus wrap can be a favourite against top set; check the hand breakdown table under the results to see how often each hand ends as a straight, flush or full house. Because equities run so close, position and betting size matter more than the raw cards, and the pot odds calculator and EV calculator can quantify how much.
Sample PLO matchups
| Hand 1 | Hand 2 | Equity |
|---|---|---|
| A♥A♦K♥K♦ | J♠T♠9♣8♣ | 61.5% / 38.5% |
| A♠A♥K♠K♥ (top set on 7♠6♠2♦) | J♠T♠9♣8♣ | 34.4% / 65.6% |
| K♠K♥Q♠J♦ | A♠A♥7♣2♦ | about 41% / 59% |
| J♠T♥9♠8♥ | A♣K♦Q♣2♦ | about 55% / 45% |
The second row is the classic “set versus wrap plus flush draw” spot: even top set is a 2:1 underdog on the flop.
