Bug reports

If the generator produces a malformed PDF, a puzzle without a unique solution, or a setting doesn't behave as expected, please include: the browser and operating system you're using, the URL of the page, the steps you took, and ideally a screenshot. Bug reports with reproducible steps are processed first.

Feature suggestions

Got an idea for a new variant (Killer Sudoku, Diagonal Sudoku, Samurai Sudoku), a new difficulty option, a new paper size, or a new printing layout? Tell us. Suggestions that explain the use case — "I run a Sudoku club for retirees and would like a large-print layout with two puzzles per A4 page" — are much easier to evaluate than open-ended requests.

Partnerships and content collaboration

We are open to partnerships with puzzle publishers, education-focused organisations, teacher resource sites, and similar groups. We are not open to paid link placements, sponsored posts disguised as content, or backlink schemes.

Press & media inquiries

For interview requests, podcast appearances, or feature articles about the tool, please include the publication, your deadline, and the angle you're pursuing.

Legal & takedown

If you believe content on sudokupuzzlepdf.com infringes your copyright or trademark, please include: a description of the work you claim is infringed, the URL where you found the infringing content, your contact information, and a statement that you have a good-faith belief that use is unauthorised. We respond to legitimate takedown notices within 5 working days.

Privacy & data requests

sudokupuzzlepdf.com runs entirely client-side; the generator does not collect personal data, so there is generally no user data we hold to delete or export. If you have specific concerns about cookies or third-party tracking from advertising partners, please see the privacy policy or email us directly.
