Traditional casinos ask you to trust them. Crypto casinos with Provably Fair let you verify every result yourself.
How It Works
Before each bet, the casino generates a secret server seed and shows you its encrypted (hashed) version. You add your own client seed. The result is computed from both — meaning the casino cannot change the outcome after you've seen the hash.
Verification Steps
- After the bet, the casino reveals the server seed
- You confirm its hash matches what was shown before
- Input both seeds into a verifier tool and see the same result reproduced
Which Casinos Offer It
Stake, BC.Game, Roobet, Duelbits, and Gamdom all offer provably fair on their Originals games: Crash, Dice, Mines, Plinko, Keno.
Third-Party Slots
Slots from providers like Pragmatic Play and Nolimit City don't use this system, but they are RNG-certified by independent auditors (iTech Labs, GLI). The audit certificate is more important than the provider's word.
💡 Tip: change your client seed regularly for extra security.
