You don't trust your casino. Good — use our Provably Fair Verifier. No opinions, no gut feelings. Just raw numbers and pure math. Paste your seeds, pick your game, get a verdict — Dice, Crash, Plinko, Mines, Limbo and more.
There are hundreds of crypto casinos. They all claim fairness. But who verifies? We asked the obvious questions.
I spent 23 years in the pit — from dealing cards in the Caribbean to managing floors in Europe. I've watched millions of hands. I've caught every trick in the book. Now I verify fairness with code, and the math doesn't negotiate.
The Ex-Pit Boss — Founder, FairPlay Audit
The open-source tool on GitHub is a breathalyzer. Our full audit is a blood test. Both detect manipulation — but only one catches the subtle stuff.
We don't ask you to believe us. We give you the data and the tools to verify everything yourself.
Server seeds, client seeds, nonces — from actual casino rounds. No simulations. No synthetic data. Real gameplay, real stakes.
HMAC-SHA256 verification of every outcome. 32 statistical tests across 5 categories — from NIST SP 800-22 core to proprietary cross-game correlation and behavioral analysis. All at 99% confidence. See all 32 tests →
The full report, the raw dataset (CSV/JSON), the SHA-256 integrity hash, and a PGP signature. Download it. Fork our code. Reproduce our results. We hide nothing.
