PokerEquity Lab is a free Windows program that answers one question: how often does each hand win? Pick the cards, or draw the ranges you think your opponents play, and press Calculate. You get win, tie and lose percentages plus the equity for two to ten players — before the flop, or on a flop, a turn and a river. The answer is counted exactly whenever the situation allows it and estimated very closely everywhere else. No account, nothing to install and no internet connection needed.
The whole program is this one window. On the left you see the players and the deck of cards; on the right the 13x13 range grid with the paint weights and the ready-made ranges. The line at the bottom tells you what just happened. The picture above shows JJ+, AKs, AQs+, KQs:50 against Top 30%: 69.23% against 30.77% after 200,000 runouts in 0.08 seconds.
Compare two hands, two ranges or ten players — on any board. Here is what the program gives you, explained in plain language.
Add as many players as your table has. In small spots the program counts every possible runout; in big ones it switches to a fast random sample — and the status line always tells you which of the two you got.
Hold the left mouse button and drag across the 13x13 grid to add hands; drag across them again to take them away. The range text and the hand counter ("290 combos · 21.9%") follow along on their own.
Playing a hand only half the time? Paint it at 100, 75, 50 or 25 percent, or type the frequency in the range box as JJ+:50 or AKs:25. Cells painted below 100% show their weight in the corner.
Top 5, 12, 20 and 30 percent, pairs, suited aces, broadways, suited connectors, gappers or any two suited — and Random hand, which simply means "any two cards" for an opponent you know nothing about.
Click the flop, turn and river slots and pick the cards from the deck. Cards that are already in play are greyed out, so one card can never be dealt twice. Every player also gets the current hand in words, like Two pair, aces and kings.
Equity in percent, coloured from red through amber to green, plus win, tie and lose for every player. Choose how many runouts to use, and set a seed if you want to get the exact same sample again later.
Five short chapters in plain language: getting started, drawing ranges, the range text, the board, and the settings plus what is in the download.
PokerEquity Lab is a single Windows program. There is nothing to install, no extra download and no account to create — and it does not write anything outside the folder you unzip it into.
PokerEquityLab.App.exe and a short README.txt. Prefer a normal installation? Run the setup instead: it installs the program for your user with a Start Menu shortcut and an uninstaller, and it needs no admin rights.
Click Top 30% for one player and Random hand for the other, then press Calculate. Five seconds of work and you already have a baseline read — refine the range from there by painting the matrix.
The 13x13 grid is the range editor. The diagonal holds the pairs, the cells above it are suited hands (AKs) and the cells below it are offsuit hands (AKo). The counter in the top right corner tells you exactly how big the range is: 290 combos · 21.9%.
:50 means the same as :0.5.
Paint a range and the text box writes itself; paste a range into the text box and the matrix repaints. Nothing is ever hidden in one of the two views.
A range is a comma separated list of hands. Pairs are written as two equal ranks, suited hands get an s and offsuit hands an o; leave the suffix out to mean both. A weight is appended with a colon, and a single card on its own means "this card plus any other card".
| Example | What it means | Size |
|---|---|---|
AA, AKs, AKo |
A pair, a suited hand, an offsuit hand | 6 / 4 / 12 combos |
AK |
Suited and offsuit: both are included | 16 combos |
JJ+ |
JJ, QQ, KK, AA — every pair from JJ upwards | 24 combos |
AQs+ |
AQs, AKs — same high card, better kickers | 8 combos |
22-99 |
Every pair from 22 through 99 | 48 combos |
T9s-54s |
Suited connectors with the same one card gap, T9s down to 54s | 24 combos |
A5s-A2s |
Suited aces with a kicker from 5 down to 2 | 16 combos |
AsKh |
One exact combination: the ace of spades and the king of hearts | 1 combo |
As |
Every combination that contains the ace of spades | 51 combos |
JJ+:50 |
Half weight for every combo of JJ+ (also written JJ+:0.5) |
24 combos at 50% |
random or * |
Every hand at 100% — the "any two cards" range | 1326 combos |
There are 1326 possible starting hands. The counter in the corner of the grid always shows how many of them your range contains — as a number and as a percentage of all hands. "290 combos" is the 21.9% you see up there, so you can compare your own range with the charts you study.
A weight counts a hand as a fraction of itself: painted at 50% it counts as half a hand. That is how you build a mixed range such as JJ+:50, AKo:25 without leaving the program.
A range copied from your notes, your charts or a solver export usually works as-is — paste it into the range box and the matrix follows. If something cannot be parsed, the app says so under the box instead of guessing.
The board row at the top is a flop, a turn and a river waiting to happen. Press a slot, then click a card in the palette — the board stays contiguous, so you can never leave a hole in the middle of a flop.
F1, F2 and F3 are the flop, then Trn and Rvr. The label next to the row tells you where you are (Preflop, Flop, Turn, River) and what the program is about to do. Clear board empties it again.
Give both players a range, put a flop down, and press Calculate: you get the range versus range equity as well as the current hand each side actually holds. Add the turn or the river and the numbers tighten — the same scenario, one street further.
Two settings decide how the numbers are found: the mode and the number of runouts (one runout is one complete deal of the remaining cards). Everything else you can safely ignore until you need it.
AA against KK comes out as 81.9% because every deal was looked at.
12345 and you get the same sample back — handy when you compare two ranges.
PokerEquityLab.App.exe and a short README.txt, nothing else to look after. Unzip it anywhere, and delete the folder again when you are done with it. The installer version instead puts the program in your own user folder with a Start Menu entry and an uninstall button; neither version needs admin rights.
SHA256SUMS.txt on this page lists a fingerprint (SHA-256) of both files. Run certutil -hashfile "PokerEquityLab-1.0.0-win-x64.zip" SHA256 in a command prompt and compare the long string. Windows may also warn that the program is not signed yet — choose More info and then Run anyway if the fingerprint matches.
No. The program never writes a database, never touches the registry and never contacts a server. Your last scenario lives in the window while it is open, and when you close it, nothing is left behind but the folder you unzipped. Copy that folder to a USB stick and the whole program travels with it.
PokerEquity Lab is an ordinary offline program. It does not connect to a poker room, it shows nothing on your tables and it never plays for you — it is made for studying hands away from the table. What you are allowed to run while you play differs from room to room, so here is the honest picture.
| Criterion | Tools that help you live | PokerEquity Lab |
|---|---|---|
| Connection to a poker client | ❌ Trackers and HUDs attach to the client | ✓ Nothing — the app never looks for a poker room |
| Process access, hooks or injection | ❌ Reads client memory | ✓ Zero — no access to other processes |
| Network activity | ⚠️ Licence checks, hand uploads, cloud sync | ✓ 100% offline — no account, no telemetry |
| Real-time assistance (RTA) | ❌ Live solver hints and strategy advice | ✓ It computes a number when you press Calculate |
| Automation | ❌ Can click, bet or fold for you | ✓ There is nothing that could play a hand |
| Studying away from the table | ⚠️ Often restricted | ✓ The intended use — review hands, learn equities |
| Running it during real money play | ❌ Banned almost everywhere | ⚠️ Depends on the room — check the current rules first |
A calculator like this one is a study tool, and most rooms accept it away from the tables. That is not a licence to use it anywhere: read the third-party tools section of your room's rules before you run a calculator during play, and never use one as a live decision aid.
PokerEquityLab.App.exe and you are running. Nothing is added to Windows, no admin rights are needed and there is no library to register.
AA against KK is 81.9% because every deal was looked at. Big spots — many players, wide ranges — are sampled instead, and the status line says so. With the default 200,000 runouts the answer is normally within a few tenths of a percent, and you can raise the number to 5,000,000 for a tighter figure.
certutil -hashfile "PokerEquityLab-1.0.0-win-x64.zip" SHA256 and compare the long string with the file. Windows may also warn that the program is not signed yet — that is the missing signature, not the fingerprint.
Take the portable version if you would rather not install anything, or the installer if you want the program in your Start Menu with an uninstall button. Both work straight away: no account, no extra software, no admin rights. The two files are served from GitHub, because they are larger than this website is allowed to host.
The fingerprints are published in SHA256SUMS.txt. Compare them before you start the program:
Version 1.0.0 is the first Windows release and it is not signed yet, so Windows may ask for confirmation the first time you start it: choose More info and then Run anyway once the fingerprint above matches. The portable download holds PokerEquityLab.App.exe and README.txt only — delete the folder when you want the program gone.
