Shuffle publishes a provably fair mechanism for supported in-house games using hashed server seeds, client seeds and nonces. It lets a player check an outcome after the relevant seed is revealed; it does not eliminate the house edge or make every third-party slot independently verifiable.
The underlying idea
A provably fair commitment can bind the operator to a concealed server seed before a round. When the seed is subsequently revealed, the user combines it with the client seed and nonce to reproduce the game result under the published algorithm.
Commit
A hash commits to the future server seed before a result is revealed.
Play
The game uses its defined seed and nonce inputs to derive an outcome.
Verify
Once revealed, the original inputs let a player reproduce the result.
How to verify a Shuffle bet
- Open the relevant bet or provably fair information panel on Shuffle.
- Follow the operator’s instructions for rotating or revealing the necessary seed pair.
- Record the server seed, client seed and nonce of the completed bet.
- Enter those details in Shuffle’s verification tool and compare the calculated output.
The operator’s procedure is documented in its verification help article.
What provably fair does not mean
- It does not mean the player has a positive expected return.
- It does not substitute for reading RTP and house-edge information.
- It does not automatically cover every third-party studio game on the platform.
- It does not replace licensing, account security or payout due diligence.
