Formula Used
The calculator follows the Omaha rule: two hole cards plus three board cards must be used. It tests C(4,2) × C(5,3), so each player has 60 legal five card builds.
High hands use standard poker ranking. The order is straight flush, four of a kind, full house, flush, straight, three of a kind, two pair, one pair, and high card.
Low hands use ace to five ranking. The low qualifies only when all five ranks are different and no rank is higher than eight.
Net pot = pot × (1 − rake ÷ 100). If a low qualifies, high pool = net pot ÷ 2 and low pool = net pot ÷ 2. If no low qualifies, the high side receives the full net pot.
How To Use This Calculator
Enter card codes with rank first and suit second. Use AS for ace of spades, TD for ten of diamonds, and 7C for seven of clubs.
Enter exactly five board cards. Enter exactly four cards for each active player. Leave unused player seats blank. Add the pot and rake values. Then press Calculate.

Omaha Hi Lo Calculator Guide
What This Tool Does
Omaha Hi Lo is a split pot game. The best high hand can win half. The best qualifying low can win half. This calculator checks both sides with strict Omaha rules. Each player must use two private cards. Each player must also use three board cards.
Why Exact Card Use Matters
Many players misread Omaha boards. A strong looking hand may fail because only two hole cards can play. The tool tests every legal two card and three board mixture. It then keeps the highest ranked five card hand. It also checks every possible low hand under eight or better rules.
Understanding The Low Side
A low hand needs five different ranks. Every rank must be eight or lower. Aces count as low for this test. Straights and flushes do not hurt the low. The best low is A-2-3-4-5. A hand like A-2-2-4-7 does not qualify, because it repeats a rank.
Pot Sharing
The calculator starts with the pot. It subtracts the rake percentage. If a low qualifies, the remaining pot is divided into high and low halves. Tied winners share their half equally. If no low qualifies, the high winner or winners receive the whole net pot. This shows common quartering situations.
How To Use Results
Enter five board cards after the river. Add four private cards for each active player. You can name each player. Leave unused seats blank. Enter the pot and rake if you want payout estimates. Press calculate. Review the high winner, low winner, best card mixtures, and net shares.
Practical Value
Use the tool to review difficult hands after play. It helps explain scoops, chops, quarters, and missed lows. It is also useful for learning hand reading. Try changing one board card. Then compare how the high and low outcomes change.
Common Review Checks
Check whether the board offers three low cards. If it does not, no low can qualify. Check duplicate ranks in low attempts. Pairs block the low. Compare blockers too. Holding A-2 is strong, but counterfeiting can happen. When the board pairs your low card, another player may overtake you. Always study both halves together before judging the final payout at showdown.
FAQs
1. How many hole cards does this calculator use?
It always uses exactly two hole cards and exactly three board cards. That is the core Omaha rule and cannot be bypassed.
2. What makes a low hand qualify?
A low qualifies when it has five different ranks, all eight or lower. Aces count as low. Pairs block low qualification.
3. Do straights and flushes hurt the low?
No. In ace to five low ranking, straights and flushes are ignored. Only rank values and duplicate ranks matter.
4. What happens when no low qualifies?
The high winner receives the full net pot. If multiple high hands tie, those players split the full net pot equally.
5. Can one player win both halves?
Yes. A player can scoop the pot by winning high and low. The result table adds both shares together automatically.
6. Why does the calculator reject duplicate cards?
A real deck has only one copy of each exact card. Duplicate card entries would create impossible hands and incorrect payouts.
7. How many players can be compared?
This page supports up to four active player seats. Enter four cards for each seat you want included in the calculation.
8. What export options are included?
You can download the displayed results as a CSV file or a PDF file. Both exports use the latest calculated result.
