What does provably fair mean?
A cryptographic method that lets you check a game result wasn't changed after you bet. The game publishes a hash of a secret server seed before the round and reveals the seed afterwards, so you can recompute the result.

Why it matters
South African example: on a R100 bet, a 1.50x cash out pays R150. See the term in action in our Aviator South Africa guide.
It’s the best way to confirm a game is fair before you commit to it.
In practice
To use it, note the hashed server seed before you play, then open the fairness panel after the round to see the revealed seed, client seeds and nonce. Our verifier can recompute hashes in the generic HMAC-SHA256 method; each game’s own formula is in its documentation.
Example
Hash the revealed server seed and check it matches the pre-round hash.
