Reproducible bug report
A report can include tool name, cards, mode, seed, iterations, expected behavior, and actual behavior without an account.
About Poker Odds Calculator
Poker Odds Calculator is an educational mathematics project for reviewing probability, made hands, and decision formulas. Its calculation engine was independently designed from public poker rules, runs in the browser, and exposes assumptions so results can be checked.
How the result is built
Your Calculation Stays in Your Browser
Card and numeric inputs are validated and calculated locally. Larger supported jobs move to a same-origin Web Worker, then render back into the page.
- Card or numeric input
- Local validation
- Browser calculation or local Web Worker
- Local result rendering
- Optional local export
Not in the calculation path
- No calculation API
- No database
- No card or bankroll upload
- No remote poker engine
Independent engine design
Cards, rule sets, five-card scoring, seven-card search, tie sharing, range expansion, and worker messages are project-owned modules written from mathematical definitions. No remote odds package or calculation endpoint is used.
How results are validated
Unit tests cover every category, low straights, kickers, board-play ties, exact outcome counts, seed reproducibility, formula boundaries, ICM conservation, and invalid inputs. Static probability generation provides a separate combinatorial check.
Editorial and privacy principles
Pages distinguish exact values, estimates, and assumptions. Google Analytics and Microsoft Clarity load by default, while calculator fields are masked from Clarity. Card inputs stay local unless a share URL is explicitly created; the site has no account or calculation database.
Worked examples
Cross-checking a formula
Worked examples use round values so pot-odds and EV arithmetic can be verified by hand.
Frequently asked questions
Is this site a poker room?
No. It offers educational calculations and no real-money play.
How can I report an error?
Use the configured contact mailbox and include a reproducible input.
Where do calculations run?
Calculations run in the browser, with high-load work delegated to same-origin Web Workers.
How are calculation changes checked?
Automated evaluator, probability, formula, and regression tests are run before release.
