Check the published inputs for demo round 42.

### Recompute the result

Use the disclosed algorithm and round inputs to compare the recorded outcome.

### Read this example

Check the published inputs for demo round 42.

1.  **Commitment recorded.** Before play: store the server-seed commitment. Client seed + nonce are recorded. _Seed remains hidden._
2.  **Seed revealed after play.** Compare the revealed seed’s hash with the original commitment. _Commitment check._
3.  **Recompute the result.** Use the disclosed algorithm and round inputs to compare the recorded outcome. _Illustrative verification replay._

This animation illustrates verification steps; it does not execute a cryptographic proof or certify randomness.

## FAQs

### Does verification prove every aspect of fairness?

No. Result verification, randomness and game-rule assessment answer different questions.

### Is independent certification included?

No. We can prepare technical evidence and support the separate review process.

### Can players check their results?

Yes, where the agreed protocol supports it. The tool makes the required records available.

## What must players be able to check?

Share your game rules and verification requirements.
