Data & methodology
Corrections policy
RTP Ledger wants to correct every wrong figure. A correction requires a source that proves the error. An assertion alone is insufficient.
How to report an issue
Email a data correction with:
- the game or casino name and a link to its page on RTP Ledger;
- the field you believe is wrong and the value you expected;
- a link to a source (ideally the provider's own rules or catalogue).
The source is the important part — it is what lets us verify rather than guess.
What happens next
- Reported — we receive the issue.
- Triaged — we confirm which field and page it affects.
- Investigated — we compare the claim against the value's current source and any higher-priority source.
- Confirmed or rejected — a value is not changed simply because someone says it is wrong; the sources have to support the change.
- Corrected — if confirmed, the value is updated and the original is preserved internally for audit.
- Validation rerun — automated checks run again over the changed record.
- Published — the corrected value goes live.
- Changelog — material corrections are logged.
The rules we hold ourselves to
- A value changes only when an available source proves the correct figure. See the source policy.
- If we cannot prove the right value, the field is set to unknown rather than left showing a suspect figure.
changedAtupdates only on a real change to the value — never on a routine deploy.- We do not hide a correction by backdating the page. A material change moves the “last updated” date forward, honestly.
For how figures are sourced and rated in the first place, see the data methodology.
