The idea in one paragraph
Before you bet, the casino picks a secret server seed and shows you only its hash, a fingerprint that cannot be reversed. You add your own client seed. Each bet also has a nonce, a counter that goes up by one per bet. The result of every bet is calculated from these three values. When you change seeds, the casino reveals the old server seed, and you can recompute every past result and confirm the hash matches what you were shown before you played.
How to check a bet, step by step
Open the fairness or seed settings in the casino and note the hashed server seed and your client seed. Play a few rounds. Then rotate the seed pair, which reveals the previous server seed. Paste the revealed server seed, your client seed and the nonce of a bet into the casino's verifier or an independent open-source one. The result must match your bet history, and hashing the revealed seed must give the hash you saw before.
Set your own client seed rather than keeping the default. That way the casino cannot have chosen both inputs.
What provably fair does not tell you
It proves that a round was not changed after you placed your bet. It does not tell you the house edge. A provably fair dice game can still keep 1%, 2% or more of every bet. Look for the published RTP or house edge alongside the provably fair badge.
It also only applies to the casino's own games. Slots and live tables from outside studios use certified random number generators that labs audit; you cannot verify those bet by bet.
Why it matters more at crypto casinos
Most crypto casinos hold offshore licences with lighter oversight than the strictest regulators. Provably fair games fill part of that gap: you do not need to trust a regulator's audit when you can check the result yourself.
How we order this page
The list shows casinos with provably fair in-house games, ordered by our overall score. Our fair-odds criterion gives the top mark only when a casino also publishes a low house edge for those games, because verifiable results and good odds together are what protect your balance.
Common misunderstandings
A provably fair badge does not mean the casino cannot change a game's rules for future rounds. It means it cannot change the outcome of a round once you have bet with a committed seed pair. If the casino updates a game's payout table, the new edge applies to new bets.
Verifying only works if you note the hashed server seed before you play. Seeds you never saw hashed in advance prove nothing. Rotate your seed pair from time to time, and verify a few random bets rather than only your losses, to get a fair picture.
Which games are usually provably fair
Dice, limbo, crash, plinko, mines, keno, towers and similar in-house titles. Some casinos also run provably fair blackjack, roulette or baccarat. Live dealer tables and studio slots are not.
Questions players ask us
No. It proves the round was not manipulated. The house edge still applies.
Almost never. Studio slots use audited random number generators instead.
Yes. Setting your own client seed means the casino did not choose both inputs.
