How Provably Fair Verification Works
What is Provably Fair?
Provably fair is a cryptographic method used by Stake, Shuffle, Winna, Duel, Thrill and Roobet that lets you independently verify every bet outcome using a server seed, client seed and nonce — without trusting the casino's word.
Supported Games
Verify seeds for Plinko, Mines, Crash, Keno, Limbo, Dice and Blackjack across SHA-256 (Stake, Shuffle, Winna, Duel, Roobet) and SHA-512 (Thrill). Thrill blackjack supports 1–3 seats.
100% Client-Side
All calculations run entirely in your browser. Your seeds are never sent to any server. You can verify results offline or inspect the source code at any time to confirm the logic matches each casino's published algorithm.
