How the result is generated
- Server seedGenerated in advance; its hash can be seen before the round.
- Player seedsSeeds from three players in the round join the mix, giving them no advantage.
- Combined hashThe seeds are joined and run through a SHA-512 function.
- MultiplierPart of the hash is turned into a number and then into the round’s multiplier.
Because player seeds are only known when the round starts, neither the operator nor the developer can choose the result alone.
How to verify a round
- Open the historyClick a past round’s multiplier at the top of the screen.
- View the dataServer seed, player seeds and combined hash.
- RecalculateUse an independent SHA-512 calculator with the same seeds.
- CompareThe hash and multiplier must match what the game shows.
You can also change your client seed in the game settings.
What Provably Fair does not guarantee
- It does not guarantee profit: the RTP is still 97%.
- It does not prove the operator will pay withdrawals — that depends on licensing and regulation.
- It does not protect you from fake sites imitating the game. Play only at licensed sites.

Frequently asked questions
Can the operator rig Aviator?
Provably Fair prevents choosing a specific round’s result without it showing up in verification. Still, play only at licensed operators.
Do I need to verify every round?
No. Verification is optional; it exists so anyone can audit whenever they want.
Does seeing the hash in advance help predict the result?
No. The server seed’s hash does not reveal the seed, and the player seeds do not exist yet.
