ROOBET SEED CHECKER

Recompute any Roobet game result from your revealed seeds and nonce. Roobet documents the Stake-style scheme this tool implements — verify one revealed round before relying on it.

Pre-set to Roobet (stake-style (by documentation)). Scheme: HMAC-SHA256(server seed, "clientSeed:nonce:cursor"). Need another casino or games side-by-side? Use the full verifier.

Calculation Breakdown

Roobet documents a Stake-style provably-fair system: server seed + client seed + nonce through HMAC-SHA256. This checker reproduces that scheme. We label Roobet Stake-style rather than verified because we matched it from documentation, not a byte-for-byte audit — so cross-check one known round against Roobet's own fairness page before relying on it for the rest.

HOW TO FIND YOUR ROOBET SEEDS

  1. Click your avatar in the top-right corner and select Fairness from the dropdown.
  2. View your current hashed server seed, client seed, and nonce.
  3. Click Change Seeds to rotate to a new pair and reveal the previous unhashed server seed.
  4. Enter the revealed server seed, client seed and nonce, choose the game, and press Verify.

Remember: the server seed is only revealed after you rotate it. Before rotation you only see its hash — that is by design, so you cannot compute outcomes in advance. Read our full Roobet review for the casino's wider track record.

WHY CHECK YOUR ROOBET RESULTS?

Checking a result proves it was computed from the server seed Roobet committed to before your bet, combined with the client seed you chose — so the outcome could not have been altered after seeing your wager. It is the difference between trusting Roobet's word and holding mathematical proof. Spot-checking a few rounds keeps the operator honest and removes doubt during a downswing.

Provably fair confirms a result was not manipulated; it does not remove the built-in house edge. For the cryptography from first principles, see what provably fair gambling is, or open the all-games verifier.

ROOBET SEED CHECKER FAQ

Roobet documents a Stake-style provably-fair system using HMAC-SHA256 with a server seed, client seed and nonce. This tool reproduces that scheme; because our match is from documentation rather than a byte-for-byte audit, verify one known round against Roobet's own checker first.
We reserve 'verified' for casinos we confirmed byte-for-byte against their published code (Stake, Shuffle). Roobet's format matches by documentation, so we flag it Stake-style and recommend cross-checking a known round before relying on the tool for all of yours.
Click your avatar (top-right) > Fairness. You will see the hashed server seed, client seed and nonce; use Change Seeds to rotate and reveal the previous server seed for verification.
The Stake-style Originals: Crash, Dice, Limbo, Roulette, Mines, Plinko and Keno. Third-party slots and live-dealer tables are not seed-verifiable.
