How Aviator Proves Each Round Is Fair
An independent look at how Aviator's provably fair system works, and how each round's crash point is generated and can be verified.

How Aviator's Fairness Actually Works
A breakdown of the provably fair mechanism behind Aviator, from the seed values involved to how a result can be checked after the round ends.
The Provably Fair Method
Each round's crash multiplier is derived from a cryptographic hash generated before the round starts, which is later revealed so the calculation can be checked.
Server and Client Seeds
The result combines a server seed, kept hidden until after the round, with a client seed players can influence, so neither side controls the outcome alone.
Checking a Past Round
After a round ends, the revealed server seed can be run through the published hashing method to confirm it matches the multiplier that was shown.
Third-Party Certification
Spribe's random number generator and round logic have been reviewed by independent testing labs that certify casino game providers.
Why Players Rely On This
Because every player can run the same verification independently, no one has to simply trust the operator's word for the outcome.
Why Provably Fair Matters
Provably fair is not a marketing label; it is a specific method that lets a player verify, after the fact, that a round was not altered.
- The crash point is fixed by a hash before betting opens, so it cannot change once a round begins.
- Server and client seed values are both published after each round for independent checking.
- The same verification method is used across every Aviator round, not only selected ones.
What Players Say About Round Fairness
I ran the seed check myself after a losing streak and the numbers matched what the interface showed, no tampering, just a bad run that round.
Daniel S.
Verified player
Understanding how the hash works made me trust the crash points a lot more than I expected to.
Emily R.
Long-time player
The seed reveal after each round is a small detail, but it is the reason I keep playing this game over similar ones.
Steven G.
Casual player
It took a few tries to understand the SHA-256 verification, but once it clicked, the fairness claim finally made sense.
Michael B.
Tech-curious player
I appreciate that the crash point isn't decided after I place a bet, the hash proves it was set beforehand.
Lisa V.
Regular player
Checking the round hash became part of my routine after a big win, just to be sure it lined up.

Where to Play With Confidence

Verifying a Round in Three Steps
A short walkthrough for checking the fairness of a round after it has finished.
Note the Round's Hash
Before the round starts, the game displays a hashed value that represents the outcome, without revealing the multiplier itself.
Let the Round Play Out
Place a bet or simply watch as the multiplier rises and the round ends with a visible crash point.
Compare the Revealed Seed
After the round, the seed is revealed; running it through the published hash method should produce the same value shown before the round began.
See the Verification for Yourself
The fairness check takes a couple of minutes and needs no technical background beyond copying two values into a hash calculator.

How Round Verification Has Evolved
A look at how Aviator's fairness system has been documented and improved over time.
Publishing the Method
The hashing method behind each round's crash point was documented and made available for players to review.
- Independent testing labs reviewed the random number generator.
- The hash-then-reveal method was explained in plain language for non-technical players.
- Example calculations were published so anyone could reproduce the check.
Independent Certification
External testing agencies certified the game's RNG and round logic against standard fairness benchmarks used across the casino industry.
- A recognised testing lab reviewed the RNG output for statistical randomness.
- The certification report is renewed periodically rather than issued once.
- Certification covers the round math, not the operator's own site or promotions.
Open Verification Tools
Simple browser-based tools let players paste in a round's seed values and get an instant match or mismatch result.
- A free SHA-256 calculator is enough to check most rounds manually.
- Some third-party sites automate the check across many rounds at once.
- No login or account is required to run a verification.
Wider Player Education
Ongoing work to explain provably fair verification in more languages and in shorter, clearer steps for first-time checkers.
- Step-by-step guides aimed at players with no coding background.
- Short video walkthroughs of the verification process.
- A glossary of the terms used in fairness documentation.
