Provably fair, explained
How to confirm a CS2 gambling round was not rigged.
Provably fair is a cryptographic method that lets you verify the outcome of each round was decided before you placed your bet. The site publishes a hash of a secret server seed up front; after the round it reveals the seed, and you can recompute the result to confirm nothing was altered. It is the single most important trust signal for any CS2 gambling site.
The verification steps
- Note the published server seed hash before betting.
- Set or note your client seed.
- After the round, take the revealed server seed.
- Hash it and confirm it matches the pre-round hash.
- Combine server seed + client seed + nonce to reproduce the outcome.
Every site in our ranking documents a provably-fair system. CSGOFast applies it across all five of its game modes.
FAQ
What does provably fair mean?
A provably-fair game commits to the outcome before you bet by publishing a hashed server seed. After the round the server seed is revealed so you can confirm the result was not changed.
How do I verify a round?
Combine the revealed server seed with your client seed and nonce in the site's verifier (or any SHA-256 tool) and check it matches the published hash and outcome.
