Provably Fair

Fairness you can verify, not just trust

BND uses cryptographic technology that makes it mathematically impossible for the server to manipulate round results. Every outcome is generated before the round starts and can be independently verified by anyone after it ends.

1

Server commits before the round

Before each round, the server generates a secret seed and locks it in.

2

Your seed shapes the result

Your client seed combines with the server seed and an incrementing nonce. The server alone cannot control the outcome — your randomness is part of the formula.

3

Verify after the round

Once the round ends, the server seed is revealed. Anyone can recompute the result and confirm nothing was changed.

Not just the outcome

Platform layouts are verifiable too

Every platform position and multiplier in our crash games comes from the exact same seed as the crash point — nothing is randomly assigned outside the provable system.

For the technically curious

The formula

crash multiplier = max(1, (1 / (1 − r)) × 0.97)
where r is derived from HMAC-SHA256(serverSeed, clientSeed:nonce)

A 3% house edge is built directly into this formula — the same number everywhere, no hidden adjustments.

Every one of our games includes a built-in verification calculator — open any game page to try it yourself.
