Frequently asked questions
Are these poker tools really free?›
Yes. All 54 tools work without payment. A few have a free allowance rather than no limit: the AI hand reviewer gives 10 reviews a day, the AI leak report 3 reports a month, and Solver-lite 9 of its 33 spots. PRO removes the AI limits and ELITE opens every solver-lite spot; every calculator and chart is free with no cap.
What is the difference between the pot odds calculator and the odds calculator?›
The pot odds calculator tells you the price: the share of the pot you must win for a call to break even. The odds calculator tells you your equity: how often your hand actually wins against another. A call is profitable when your equity is higher than the break-even share. For draws, the outs calculator counts the cards that improve you against a specific hand.
Can I use these tools while I am playing?›
No. They are built for study between sessions. Using any calculator or chart for decisions during a hand is real-time assistance, which every major poker site bans and can close accounts for.
Is there a calculator for Omaha, 5-card PLO and 6-card PLO?›
Yes. The PLO equity calculator handles 4, 5 and 6-card Omaha and enforces the rule that you must use exactly two hole cards. It scores the high hand only.
How accurate are the calculators?›
The equity calculators use Monte Carlo simulation: the odds calculator runs 80,000 trials per result, accurate to about 0.3 percentage points, and results vary slightly between runs. For exact figures, the hand matchup pages count every possible board.
Do the tools work on a phone?›
Yes. Everything runs in the browser, so there is nothing to install, and the calculations happen on your device.
