1. Why Verify Game Fairness Yourself?
Provably fair systems give players transparency by allowing verification of outcomes using seeds, hashes, and nonces. But manually computing details for every round is tedious. Fortunately, free third-party tools and scripts exist to help you confirm fairness quickly.
2. BTCGOSU Provably Fair Verifier — Plug & Play
BTCGOSU’s online verifier is one of the largest third-party tools, supporting over 50 games across 27 casinos. Just copy your game’s:
- casino name
- game name
- server seed (and its hashed form if available)
- client seed
- nonce
Then paste them into the tool — it verifies both seed integrity and actual outcome. Simple and effective.
3. Stake’s Native Verifier & Third-Party Option
On platforms like Stake:
- Navigate to your bet history and click Provable Fairness.
- Optionally rotate your client seed for replayability.
- Review the hash, clear breakdown, and verification UI.
- Want a second check? Copy the details into the third-party verifier via sites like provablyfair.me.
4. Open-Source Verification Tools & Scripts
For developers and power users, open-source tools let you verify offline:
- GitHub
provably-fair-app
: A browser-based verification app under Apache-2.0 license — load bet seeds and verify results locally. - Rune-Server scripts: Java and HTML/JS verifiers for game types like dice and poker; use the “Verify Game Result” UI or delve into source code.
5. Step-by-Step: Verifying a Dice Roll
- Before playing, copy the hashed server seed.
- After the round, note the revealed server seed, client seed, nonce, and result.
- Use a tool:
- Online: Paste values into BTCGOSU or similar.
- Locally: Use
provably-fair-app
or Rune-Server scripts.
- Verify:
- Does
hash(server_seed)
match the pre-play commitment? - Does recomputed outcome align with the displayed result?
- Does
- Any mismatch? That’s grounds for concern — document it immediately. Tools automate this workflow strongly.
6. Community Perspective
On Reddit, players emphasize transparency:
“The hash is generated and mixed with the server seed—every round has its own hash. No one knows the result before placing a bet.”
And users point out: once seeds mismatched:
“If it doesn’t match, you are getting scammed :(”
