What Provably Fair Actually Means

The phrase gets used loosely. This is the actual mechanism — seeds, hashes, and how you can verify a round after it has finished.

The problem it solves

In a fast, software-driven game such as Aviator, the result of each round is a number produced by a computer. The obvious question is how anyone can know that number was not changed after bets were placed. Provably fair is the answer: a way of committing to a result before the round begins, and proving afterwards that the commitment was kept.

Seeds

A seed is a starting value from which a result is calculated. A provably fair round combines more than one:

• A server seed, generated before the round starts and kept secret until it ends.
• Client seeds, contributed by players taking part in the round.

The result is derived from the combination. Because players supply part of the input, the operator cannot know the outcome in advance simply by choosing its own seed.

Hashes

A cryptographic hash function turns any input into a fixed-length fingerprint. Two properties matter here: the same input always produces the same fingerprint, and it is not practical to work backwards from the fingerprint to the input, or to find a different input that produces the same one.

Before the round, the game publishes the hash of its server seed. That is the commitment — it fixes the seed without revealing it.

The hash is a sealed envelope. You can see it on the table before the round, but you cannot read what is inside until it is opened.

Verifying a round

1. Before the round, note the published hash of the server seed.
2. After the round, the server seed itself is revealed.
3. Hash the revealed seed. It must produce exactly the hash that was published beforehand — if it does, the seed was not changed.
4. Combine the server seed with that round's client seeds using the published method, and confirm the calculation gives the multiplier the round actually showed.

The round history in the game shows the seeds and hashes for past rounds, and independent tools can run the calculation, so you never have to take the game's word for it.

What it does and does not tell you

Provably fair proves that a round's result was fixed before the round began and was not altered afterwards. It does not change the odds of the game, and it does not make any outcome more predictable. Every round is independent: a run of low multipliers says nothing about what the next round will do.

Staying in control

Aviator rounds last seconds, so stakes add up much faster than in a match-based game. Decide a limit and a session length before you start, use auto cash-out to take the pressure out of reacting in the moment, and treat any stake as the cost of entertainment.
