Committed before
the bet. Verified after.

Every round is sealed with a cryptographic commitment before you stake a lamport. When the seed is revealed you can recompute the result yourself — and confirm the house never had room to change it.

Reading the live round — not a mockup

The floor

Four games, one fairness model

Crash

Ride the multiplier. Cash out before the rocket does.

One shared round, every player on the same curve. Auto-cashout, live player list, seed revealed the moment it crashes.

Mines

Twenty-five tiles. You pick how dangerous.

1–24 mines, cash out at any depth.

Coinflip

One call, settled instantly.

1.9× on heads or tails.

Blackjack

Full table rules, no shortcuts.

Split, double, insurance and side bets.

Fairness

You don't have to trust us.
You can check.

Two values per round. One is published before you bet, the other after the round ends. Together they prove the result was fixed in advance and that nobody could have altered it once your stake was down.

Every game exposes both from its Provably Fair panel, along with the exact algorithm, so you can reproduce any round offline.

Before the round

We publish a commitment

A server seed is generated and kept secret. Its SHA-256 hash is broadcast to every client before betting opens.

publicHash = SHA256(serverSeed)
After the round

We reveal the seed

Hash the revealed seed and it must equal the commitment you already had. Then derive the outcome yourself.

outcome = HMAC(serverSeed, "crash:v2:" + roundId)

Why the two values are computed differently

The commitment is a plain hash of the seed; the outcome is an HMAC keyed by that same seed. Deriving both from one digest would be a critical flaw — the published hash would be the answer, and anyone could read the result off it before placing a bet. Keeping them independent is what makes publishing the commitment safe.
