Contact Worldoku

We’d love to hear from you.

Whether you’ve spotted a factual error in a puzzle, found a bug, have a feature idea, or want to get in touch about anything else, email us at [email protected] and we’ll get back to you.

Worldoku’s country data is compiled from public, authoritative sources, but the world changes and mistakes happen — corrections are always welcome. If you’re reporting a puzzle issue, telling us the date, difficulty and the cell in question helps us track it down fast.

For details on how we handle your data, see our privacy policy.

Worldoku is an independent project and is not affiliated with any organisation referenced in its puzzles.
