Have Questions About Fairness?
This casino's games are independently audited by ProvablyFair.org — a third party with no affiliation to the casino. We test the RNG implementation, verify the cryptographic commit-reveal process, and run statistical analysis across tens of thousands of real bets. If something doesn't look right, the tools and information on this page can help you check for yourself.
Common Concerns
Is This Game Rigged?
We hear these questions a lot. Most of the time, the game is working exactly as it should — the issue is that gambling math is deeply unintuitive. Click any concern below for an honest explanation.
Why it matters
What a ProvablyFair.org Certification Means
“Provably fair” is a technical mechanism, not a guarantee. The cryptography proves a result wasn't tampered with — it doesn't tell you whether the odds are what the casino claims or whether the RNG has been properly implemented. An independent audit tests the things that “provably fair” alone can't.
Real Bets, Not Just Simulations
Anonymous accounts the casino can't identify, tens of thousands of real bets on the live production environment — the same games you play. No sandbox, no special treatment.
Statistical Rigor
Chi-squared testing, runs tests, autocorrelation analysis, and Monte Carlo simulation across millions of rounds. We don't check a few bets and call it fair — we test whether the math holds at scale.
Game Integrity Testing
Every game is tested against dozens of integrity checks: can the casino predict your bets? Are seeds reused or manipulated? Does the RNG behave differently at higher bet amounts? If any single check fails, the game doesn't pass.
Independence
Not owned by or affiliated with any casino. Flat audit fee. Every report is open-source and fully reproducible — anyone can re-run our tests and verify our findings.
Any casino can claim to be provably fair. ProvablyFair.org is the independent third party that tests it — and publishes the evidence for anyone to verify.
Verify It Yourself
Verify Any Bet Yourself
Don't trust us — check the math yourself. Paste your bet details below and we'll recompute the result using the exact same algorithm. If the casino's result matches, the bet was fair. If it doesn't, report it below.
Game Verifier
Enter the round data. The result is calculated from the code we audited - compare it with what the casino showed you.
