Frequently Asked Questions
What is this tool?
A free poker equity calculator that runs right in your browser. Enter hand ranges, click Run, and get results in seconds.
What games are supported?
Hold'em, Omaha Hi (PLO4), Omaha Hi/Lo (4-card), 5-Card Omaha Hi, 5-Card Omaha Hi/Lo, 6-Card Omaha Hi, Stud Hi, Stud Hi/Lo, and Razz.
How accurate are the results?
Results use Monte Carlo simulation with configurable iterations (2,500–50,000). Higher iteration counts produce more precise results but take longer. Adaptive stopping auto-converges when results stabilize.
How is my data stored?
Saved ranges and history are stored on your local device only.
What does "Explain" do?
Translates your range notation into plain-English descriptions so you can verify you entered what you intended.
What are combo counts?
The number of specific card combinations that match your range expression. Shown beside each hand input after you type a valid range.
What are saved ranges?
You can store frequently used ranges with a name, then reference them in any hand input by typing the macro name (e.g. $cutoff_open). Use the save icon next to any hand input to save.
What is weighting (@)?
Append @50 to a range to use 50% of its combos. For example, AA@50 means pocket aces at half frequency. Works with any percentage from 1–100.
What is adaptive stopping?
The simulation can stop early when results have converged. It uses a 3-checkpoint ring buffer to verify stability before halting, ensuring accurate results with fewer iterations.
Why no combo counts for PLO6?
6-card Omaha has 20M+ possible combinations. Auto-counting is disabled for this game type to prevent mobile browser crashes. Counts are still calculated on blur.
