Aviator has a provably fair feature that lets players check completed round results. SPRIBE, the game's developer, explains how the verification process works.
What does provably fair mean in a crash game?
A provably fair system works by committing to information before a round and making the necessary values available for verification afterwards.
Players can check whether the recorded result matches the disclosed data and the game's documented calculation. This isn't an independent audit of the entire game or casino.
How does provably fair work in Aviator?
Aviator uses a server seed and client seeds to generate its results.
A seed is a value used in a calculation. The game server provides one, while player-generated values also contribute to the outcome.
Before the round, a hash of the server seed is published. Think of it as a digital fingerprint: it doesn't reveal the seed, but the original value can later be checked against that fingerprint.
Aviator uses SHA-256 to publish a hash of the server seed. SHA-512 is involved in calculating the round result from the seed values.
To verify the final multiplier, you need more than the published hash. You also need the relevant seed values and SPRIBE's documented calculation.
How can you verify an Aviator round?
SPRIBE provides a verification feature in Aviator.
To check a completed round:
- Open the game's round history.
- Select the round you want to inspect.
- Look for the Provably Fair icon.
- Review the displayed server seed, player seeds, combined hash and result.
- Follow SPRIBE's verification method to check whether the data produces the recorded multiplier.
A successful verification involves two checks. First, the revealed server seed should produce the same SHA-256 hash that was published before the round. Second, the game's documented calculation using the relevant seed values should reproduce the recorded result.
If either check doesn't match, review the inputs and round reference before reporting a discrepancy.
The Provably Fair Settings section also includes Next server seed SHA256, which shows the hashed server seed before a later round, alongside available client-seed settings.
The layout may vary between game clients, so check the help section if you can't find these controls.
Can you predict the next crash point using a hash?
No. A published server-seed hash doesn't reveal the upcoming multiplier.
Claims that a Telegram bot, app or website can predict Aviator rounds by decoding this hash aren't evidence of a working prediction method.
Are JetX and Aviamasters provably fair too?
JetX is developed by SmartSoft Gaming, and Aviamasters by BGaming.
SPRIBE's verification method is specific to its implementation. You shouldn't assume the same calculation applies to other games.
The public JetX description reviewed for this guide doesn't establish an equivalent player-facing verification procedure.
Aviamasters uses a landing-based result rather than classic mid-round Cash Out. That difference doesn't establish whether a particular version offers cryptographic verification.
If either game is labelled provably fair, check whether the developer provides the data and instructions needed to verify a completed result.
Is provably fair the same as RTP?
No. Provably fair is about verifying results. RTP is about the game's theoretical return over time.
A game can have verifiable results while still having a house edge. Our RTP guide explains the mathematics.
Does provably fair mean a casino is licensed in Ghana?
No. The game's verification method doesn't establish whether the casino is authorised to accept real-money bets.
The Gaming Commission of Ghana publishes a register of licensed operators. Before gambling for real money, check the operator's trading name, licence category and licence expiry date.
Cryptographic verification also doesn't confirm that a casino will process withdrawals correctly.
What if an Aviator result fails verification?
First, check that you've selected the right round and entered the correct seed values. Using an incomplete or incorrect calculation can produce a mismatch.
If the discrepancy remains, keep the round reference, verification data, recorded result and any relevant screenshots. Send them to the casino's support team and ask for an explanation.
For unresolved complaints involving a gambling operator in Ghana, the Gaming Commission provides a way to submit supporting evidence.
Does provably fair make crash games safer to play?
Verifying a result doesn't remove the financial risk of gambling. A round can pass a cryptographic check and still end with a lost stake.
If you decide to gamble for real money, set a spending limit you can afford to lose. Our Responsible Gambling guide covers gambling-related risks and support available in Ghana.
