FAIRNESS CHECK

Shuffle provably fair games: how verification works

Learn how Shuffle Originals use server seeds, client seeds and nonces, what a hash proves and how to verify a completed round.

01

What provably fair means on Shuffle

Provably fair is a cryptographic system for checking that an in-house game result came from committed inputs rather than being changed after the bet. Before play, Shuffle exposes a hash of its hidden server seed. The completed seed can later be compared with that commitment.

The system makes individual rounds independently auditable. It does not remove the house edge, predict the next result or guarantee that a player will win.

02

Server seed, client seed and nonce

A game result is derived from the hidden server seed, a client seed and a nonce that changes as bets are placed. Together, those inputs produce the reproducible output used by the game.

  • Server-seed hash commits Shuffle to a hidden value
  • Client seed adds a player-visible input
  • Nonce separates consecutive bets using the same seed pair
  • Revealed inputs let the finished result be recalculated
03

How to verify a Shuffle round

Open the fairness details for a completed Original, rotate or reveal the seed pair when required, and enter the recorded inputs in Shuffle’s verifier. The calculated result should match the game history.

Save the bet identifier and inputs if you believe the result differs. Official support can investigate the account record, while this independent guide cannot access it.

04

Which Shuffle games use it?

The verifier applies to Shuffle Originals such as Dice, Mines, Plinko, Crash and related in-house games. Third-party slots and live-dealer tables use their provider’s RNG, certification or physical studio controls instead.

QUICK ANSWERS

Shuffle provably fair games: how verification works FAQ

01Can provably fair games still have a house edge?

Yes. Verification checks how a result was generated; it does not change the game’s payout table or house edge.

02Does provably fair apply to every Shuffle slot?

No. Shuffle’s cryptographic verifier is for supported Originals. Third-party slots use the provider’s systems.
