Check an Aviatrix round

Paste a finished round's data from your bet history — we'll match the hash and recompute the multiplier. Nothing leaves your browser.

Result

Waiting for data
—recomputed multiplier
—sha256(server seed)

Calculation steps

  1. sha256(server seed) is compared with the published hash
  2. HMAC-SHA256(server seed, client seed:nonce)
  3. First 52 bits → number h
  4. h → multiplier with a 3% edge

[A generic crash-game formula is used for now. Replace it with Aviatrix's exact algorithm from the developer documentation.]

How it works

01

Before the round

The server seed hash is published.

02

Bets

Players add client seeds.

03

Crash

The multiplier is derived from seeds and nonce.

04

After

The seed is revealed — anyone can verify.

Limitation: a check confirms a past round; it can't predict the next one.

Round check FAQ

Where do I get the round seeds?

In your bet history: a finished round has a verify button with seeds and nonce.

Can a casino change the result?

The server seed hash is published before the round — any change would break the match.

Can the hash reveal the next multiplier?

No. The hash is one-way and the seed is only revealed after the round.
