Poker Equity Calculators

How These Poker Equity Calculators Work

Each calculator uses Monte Carlo simulation to estimate hand equity by running thousands of randomized scenarios. Deal your hole cards, set the board cards for any street from preflop through the river, and calculate your winning probability against multiple opponents. All simulations run entirely in your browser — your hand data never leaves your device.

No Limit Texas Hold'em

The Hold'em calculator handles standard No Limit Texas Hold'em where each player receives two hole cards and shares five community cards on the board. Players make the best five-card hand from any combination of their two hole cards and the five board cards. Calculate equity at any street — preflop, flop, turn, or river — for up to six players. The calculator shows win percentage, tie percentage, and total equity for each player, with configurable simulation iterations up to 200,000 runs for high-precision results.

Omaha Poker Rules Used

All Omaha-based calculators enforce standard Omaha rules: you must use exactly two hole cards from your hand combined with exactly three community cards from the board to make your best five-card poker hand. Hi-Lo variants use the 8-or-better qualifier — a low hand must contain five unpaired cards ranked eight or lower, with aces playing both high and low. When no qualifying low exists, the high hand wins the entire pot.

Pot Limit Omaha (PLO)

The PLO calculator handles standard 4-card Pot Limit Omaha where each player receives four hole cards and must use exactly two of them combined with three of the five community board cards to make the best possible five-card poker hand. The highest hand wins the entire pot. Calculate equity at any street from preflop through the river for up to five players with configurable Monte Carlo simulation iterations.

PLO8 — Pot Limit Omaha Hi-Lo 8 or Better

PLO8 is the split-pot variant of 4-card Pot Limit Omaha. The pot is divided between the best high hand and the best qualifying low hand. A low hand must contain five unpaired cards ranked eight or lower, with aces counting as low. If no player has a qualifying low, the high hand scoops the entire pot. The PLO8 calculator shows high equity, low equity, scoop probability, and three-quarter pot scenarios where a player wins one half outright and splits the other.

Big O — 5-Card Omaha Hi-Lo

Big O plays like PLO8 but each player receives five hole cards instead of four. You still must use exactly two hole cards and three board cards for both your high and low hands. The extra hole card creates significantly more hand combinations, making for bigger draws and more action. The Big O calculator provides the same full equity breakdown as PLO8 — high equity, low equity, scoop percentage, and three-quarter scenarios — accounting for the additional combinations from the fifth card.

Double Board Omaha

Double Board Omaha deals two separate five-card community boards. Each board is worth half the pot, and the best hand on each board wins that half. Players can use different two-card combinations from their hole cards for each board. If the same player wins both boards, they scoop the entire pot. The calculator evaluates equity across both boards simultaneously, showing each player's overall equity as a combination of their chances on Board 1 and Board 2.

2-7 Triple Draw Lowball

The 2-7 Triple Draw calculator follows standard deuce-to-seven lowball rules where aces are always high, straights and flushes count against your hand, and the lowest five-card hand wins. The best possible hand is 7-5-4-3-2 of mixed suits. Set your hand, track opponent draw counts across three draw rounds, and assign opponent ranges including 7-low, 8-low, or 9-low profiles with or without a deuce.

A-5 Triple Draw Lowball (Ace-to-Five)

Ace-to-five triple draw lowball is the other major triple draw variant, with rules that differ significantly from 2-7. In A-5 lowball, aces are always low, making them the best card in your hand rather than the worst. Straights and flushes do not count against you, so the best possible hand is A-2-3-4-5 — known as the wheel — regardless of suits. The only hand categories that hurt you are pairs, trips, two pair, full houses, and quads. The calculator lets you set your hand, track opponent draw counts across three draw rounds, and assign opponent ranges including wheel draws, 6-low, 7-low, 8-low, and 9-low profiles with or without an ace. Strategy-weighted simulation automatically discards paired and high cards for opponents.

Badugi

Badugi is a draw poker lowball game where each player receives four cards and the goal is to make the lowest hand with all four cards in different suits and different ranks. A four-card badugi — four cards of four different suits with no paired ranks — always beats any three-card hand. Aces play low, making A-2-3-4 of four different suits the best possible hand. The calculator lets you set your hand, choose which draw street you are on, and assign opponents preset ranges including made badugis with configurable high card limits or three-card draws like A-2-3, 3-card ≤5, or 3-card ≤8. Opponent draw counts are tracked across all three draw rounds with strategy-weighted simulation.
