What this proves — and what it doesn't. This tool verifies integrity: that the server seed matches the hash committed before the round, and that the revealed seeds reproduce the round hash Aviator showed you. It does not reproduce the crash multiplier — Spribe does not publish the exact hash-to-multiplier formula, and we don't guess at it. Provably fair proves the round was not altered after you bet. It does not prove you will win, and it does not prove the casino will pay out. Anyone selling an “Aviator predictor” that claims to forecast the crash multiplier is running a scam — here is the mathematical proof. Read: is Aviator trustworthy?

1 · Server-seed commitment (SHA-256)

Did the revealed server seed really match the hash shown before the round?

2 · Round hash (SHA-512)

Do the revealed seeds reproduce the round hash Aviator displayed? Enter the three client seeds (from the first three bettors) and the nonce, then paste the round hash to compare — the tool tries the known concatenation orders and tells you which one matches.

How it works: Before each round Aviator publishes SHA-256(server_seed) — the sealed envelope. Aviator then combines the server seed with the client seeds of the first three bettors (and a nonce) into a SHA-512 hash that drives the round. After the round the server seed is revealed, so you can recompute both hashes and confirm nothing was swapped. Because Spribe does not publish the exact byte order of the concatenation, this tool tries the documented orders and reports which one reproduces your panel's hash.
