Your equity
What you end up with
A Big O poker odds calculator matters because nobody’s instincts are any good in this game. Five-card Omaha hi-lo deals so many cards that hands run close and pots get split constantly. Put A♠2♦3♥K♠Q♦ up against K♥K♣J♠T♠9♥ before the flop: the ace-deuce hand has a nut-low draw and a suited ace, and it’s about 62% to win the pot in equity terms, despite the other player holding kings. The free calculator above runs thousands of boards and splits every pot the way a dealer would.
How the Big O poker odds calculator works
Each player must use exactly two hole cards and three from the board, for the high hand and separately for the low. A qualifying low needs five different cards of eight or lower; ace counts as low. If nobody qualifies, the high hand takes everything. Otherwise half goes to the best high and half to the best low, and the calculator splits ties within each half too.
Alongside overall equity you’ll see how often each hand scoops (wins both halves) and how often it wins the low. In Big O those numbers matter more than the equity figure: a hand that’s 50% but never scoops is weaker than it looks, because it’ll be quartered a lot.
A few things the numbers show quickly
- A-2 with another low card and a suited ace is the dream start. A-2 alone with junk is much weaker than in four-card Omaha, because everyone else has more low cards too.
- High-only hands like K-K-Q-J-T need the board to come high. When it does, they scoop; when three low cards land, they’re playing for half at best.
- Counterfeiting is brutal. An A-2 low loses a lot of value when an ace or deuce hits the board.
For four-card PLO and five-card PLO high, use the Omaha odds calculator. For Hold’em, it’s the poker odds calculator.
