Stake Provably Fair Verifier & Game Simulator
Free tool to verify any Stake Engine bet outcome from your account, or to simulate any game over millions of spins. Outputs match Stake's official verifier exactly. Supports every Stake Engine game on Stake.com and Stake.us — currently 1,220 games from 346 publishers.
How to verify a Stake bet
- Pick the game and mode from the dropdown.
- Paste your bet's client seed, server seed (the UNHASHED revealed value), and nonce.
- Hit Verify Bet — the tool reproduces the exact roll, event index, and payout multiplier locally using HMAC-SHA256.
Why bets need a revealed server seed
While a Stake seed pair is still active, only the SHA-256 hash of the server seed is published — this is a commitment proving the seed wasn't changed after the fact, but it cannot reproduce bet outcomes. To verify a bet, rotate your seed pair under Account → Settings → Provably Fair, which reveals the previously-active server seed in your bet history. Then verification works.
Simulating a game
Pick any number of spins (up to 20 million) and the tool replays the same HMAC-SHA256 → uint128 → mod weight-sum pipeline used by Stake Engine to roll every spin. Results include: empirical RTP versus the published RTP, total payout, full hit-rate distribution bucketed by multiplier ranges (0×–0.1×, 0.1×–1×, 1×–2×, … up to 100,000×), and a Player Experience chart showing the running balance as it would have unfolded for an actual session.
