Compliance

Fair by design. Responsible by default.

Every Aurium round can be verified by anyone, the maths are fixed and identical for every player, and the game is built for licensed, adults-only play.

Every result is sealed before anyone bets and can be verified after the round. Open any topic below — each one comes with a diagram.

01What is SHA-256?

SHA-256 is a cryptographic hash function: it turns any piece of data into a fixed 64-character “fingerprint”. It only works in one direction — you can create the fingerprint from the data, but never recover the data from the fingerprint. Change a single character of the input and the fingerprint changes completely.

One character changed (2 → 3), a completely different fingerprint. These are real SHA-256 results — anyone can reproduce them.
  • Same input, same output — always, on any computer in the world.
  • One-way — the original data cannot be worked out from the fingerprint.
  • Unique in practice — finding two different inputs with the same fingerprint is not feasible.
02Sealed before you bet

Every round follows the same four stages. The key is that the result is already fixed — and its fingerprint is shown — before anyone places a bet.

  1. 1SealThe round's seed was created in advance. Its SHA-256 fingerprint is shown before the round.
  2. 2BetPlayers place their bets during the 6-second window. The outcome is already fixed.
  3. 3PlayThe plane climbs. The chain locks at the point that was decided by the sealed seed.
  4. 4RevealThe seed is revealed with the result, so anyone can check it against the fingerprint from stage 1.

Think of a sealed envelope: the result goes in before the round, everyone sees the sealed envelope during play, and it is opened in front of all players at the end.

03Where the crash point comes from

The moment the chain locks is never chosen by a person. Each round uses the next seed from a long chain of seeds that was generated and sealed in advance. That seed is combined with a public value taken from a Bitcoin block that was mined after the chain was sealed — something nobody could know or choose beforehand. The result is turned into the crash multiplier by a fixed formula with the 97% RTP built in.

  • Sealed seed chain — all seeds are created before play and the chain's fingerprint is published, so rounds cannot be swapped, skipped or re-ordered.
  • Public Bitcoin value — it is announced before the block even exists, so neither the studio nor the casino can predict or choose it.
  • Fixed formula — the same for every round and every player, independent of who bets or how much.

✓ Match — the round was decided before any bet and was not changed.
  1. Open the Provably Fair · SHA-256 window in the game. It shows the current round's fingerprint, the previous seed and the public Bitcoin value.
  2. Any round can be recalculated right there, in your browser — no extra tools needed.
  3. Or copy a revealed seed into any SHA-256 tool and compare the result with the fingerprint shown before that round.
  4. If they are identical, the round was fair — and the same data recalculates the exact crash multiplier.
05Why the result can't be changed
Sealed in advance

The whole chain of seeds exists before play starts and its fingerprint is public. Changing a single seed would break the chain — and everyone would see it.

An unpredictable public value

It comes from a Bitcoin block mined after the chain was sealed, so nobody — not us, not the casino — could pick it.

It only works one way

Seeing a fingerprint gives no clue about the result, so it can't be used to predict a round.

Decided on the server

The crash point never leaves the server before the crash. The game in your browser only displays the round.

Fair maths

The same game for everyone.

97% RTP

A fixed return to player of 97%, built into the formula that turns each sealed result into a crash point.

Identical for every player

The crash point does not depend on who plays, how much is bet or how many players are in the round.

Tested over millions of rounds

The maths model is verified by automated tests, including a distribution check over millions of rounds.
