STAKE SEED CHECKER

Stake is the casino that popularised the modern provably-fair model, and this checker reproduces its scheme exactly: HMAC-SHA256(server seed, "clientSeed:nonce:cursor"), confirmed byte-for-byte against Stake's published implementation. Paste your revealed seeds below to verify any Crash, Dice, Limbo, Mines, Plinko, Keno or Roulette round you played on Stake.

HOW TO FIND YOUR STAKE SEEDS

1. Click your username in the top-right corner and open Settings.
2. Select the Fairness tab. You will see your active hashed server seed, your client seed, and your total bet count (the nonce).
3. Click Rotate (or change your seed pair). This reveals the previous unhashed server seed — the value you need here.
4. Enter that revealed server seed, your client seed, and the nonce of the specific bet, then 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 Stake review for the casino's wider track record.

WHY CHECK YOUR STAKE RESULTS?

Checking a result proves it was computed from the server seed Stake 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 Stake'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.
