Provably Fair-tjekker

Bekræft, at enhver crypto-casino-indsats blev afgjort, før du spillede, og aldrig manipuleret med. Indsæt dine seeds og nonce herunder – alt beregnes i din browser, så dine seeds forbliver private.

🔒 100% privat: al matematik kører i din browser via Web Crypto API. Dine seeds sendes aldrig til RTPspy eller andre.

Sådan verificerer du en indsats i 3 trin

  1. I casinoet roterer du dit server seed. Det afslører det rå server seed, der blev brugt til alle dine tidligere indsatser.
  2. Åbn den indsats, du vil tjekke, og notér dens nonce samt dit client seed.
  3. Indsæt det hele ovenfor sammen med det hash, du fik vist før spillet. Matcher både commitment og resultatet, var runden beviseligt fair.

What is a provably fair verifier?

It is a tool that re-runs the cryptography behind a casino bet. Using the revealed server seed, your client seed and the nonce, it reproduces the exact result the casino showed you. If the numbers match, that round was locked in before you bet and could not have been changed.

Is it safe to paste my seeds here?

Yes. This verifier runs 100% in your browser using the Web Crypto API. Your server seed, client seed and nonce are never sent to RTPspy or any server. You can disconnect from the internet and it still works.

Why doesn't my result match?

Almost always a small input error: using the hashed server seed instead of the revealed one, the wrong nonce, or a casino that converts the HMAC differently. Also note the Dice figure here uses the Stake-engine method, and other casinos may map the same HMAC another way.

Does a match prove the game is fair long-term?

No. Verification proves one round used the committed seed data. It does not prove the game's RTP, that the house edge is low, or that future bets are predictable. Anyone selling a tool that predicts future results is running a scam.

18+. Verifikation bekræfter, at en runde brugte sine forudaftalte seeds – det garanterer ikke gevinst eller forudsiger fremtidige indsatser. RTPspy er uafhængig og har ingen tilknytning til nævnte casinoer.
