Provably-fair gaming only works if the server seed actually rotates. A casino that never rotates can be audited once — but if you want to spot-check rounds you played last month, the seed has to have been revealed. Bink.bet documents its rotation cadence, makes rotation player-triggerable, and exposes the full per-account rotation history. No other U.S. social casino publishes this level of detail.
The provably-fair commit/reveal flow (explained in full here) only finalizes when the server seed is revealed. Until then, you can verify that the commitment hash hasn't changed, but you can't verify any individual round's outcome.
A rotation reveals the active seed and commits a fresh one. The reveal is what lets you spot-check every round you played under that seed. So the answer to "how often does Bink rotate" is "exactly when you want it to."
| Trigger | Cadence | Notes |
|---|---|---|
| Player-initiated rotation | On demand, any time | Available from Settings → Provably Fair. Rotating reveals the current server seed (so every prior round can be verified) and commits a fresh seed for the next round onwards. |
| First-ever round per account | On signup | Bink generates the initial seed pair on account creation. The first round automatically commits the first server-seed hash visible in your account. |
| Suspicious activity rotation | On internal flag | If Bink's automated audit detects anomalies (impossible streaks, fingerprinting against active seed) the seed is rotated and the event is logged in the per-account history. Players are notified. |
| Per-game nonce reset | Always per round | Nonce increments by 1 every round. After a rotation, nonce resets to 0 against the new server seed. This is automatic and cannot be skipped. |
| Cryptographic policy refresh | Versioned (rare) | If Bink updates the underlying provably-fair algorithm (new hash, additional inputs), every player's seed pair rotates at the cutover. The previous algorithm version stays addressable for retro-verification of historical rounds. |
/games/<game>/verify handles the arithmetic automatically.Every rotation event is logged to your account's permanent audit history with:
The audit history is downloadable from Settings → Provably Fair → "Export rotation log." The export is a signed JSON document so a third party can verify it's genuine.
