Crash
किसी भी Roobet Crash round को verify करें. Roobet client seed को per-round public key से replace करता है और हर bet के बाद दोनों seeds rotate करता है, इसलिए कोई nonce नहीं — public key per-round randomness commitment है. Math: HMAC-SHA256(serverSeed, publicKey) → 52-bit slice → 1-in-33 instant-bust check → Stake-family floor formula.
Frequently asked
Is Roobet Crash really provably fair?⌄
Yes. Roobet publishes a cryptographic commitment (the hash of the server seed) for each round BEFORE you bet. Afterwards the server seed is revealed and anyone can recompute the outcome — which is exactly what the verifier above does. If the computed result matches the shown one, the round wasn't manipulated.
How do I verify a Roobet Crash round?⌄
Paste the revealed server seed and the round public key into the form above. The verifier re-runs the official math and shows you the exact result, step by step. Everything runs in your browser — your seeds never leave the device.
Where do I find my Roobet seeds?⌄
On your Roobet account's fairness / seed page. There you can rotate the server seed: rotating reveals the old one (so you can verify all your previous bets) and commits a fresh hash for the next ones.
Can Roobet cheat on Roobet Crash?⌄
Not without getting caught. The server-seed hash is published before the bet, so Roobet can't change the seed after the fact — any change would produce a different hash than the committed one. That's what makes the game verifiable.
