Terms of use

Last updated November 13, 2026.

These terms haven't been reviewed by a lawyer. They're meant to describe plainly how this free site actually works, not to serve as a substitute for legal review before launch.

Using the site

Sudoku24x7 is free to use, requires no account, and places no limit on how much you play. You can print puzzles for personal or classroom use without asking first — see printable sudoku for teachers.

What you shouldn't do

• Scrape, republish, or resell the puzzles or written content on this site as your own.
• Attempt to disrupt the site (automated abuse, denial-of-service attempts, and similar).
• Misrepresent your use of the site in a way that would violate applicable law.

No warranty

This site is provided as-is. We've checked that every puzzle has exactly one solution and built real tests around the engine that generates and grades them (see how our puzzles are generated), but we don't guarantee the site will always be available, error-free, or uninterrupted.

Limitation of liability

To the extent permitted by law, Sudoku24x7 isn't liable for any damages arising from your use of, or inability to use, the site. It's a free puzzle site — there's no transaction, subscription, or paid service involved.

Changes to these terms

These terms may be updated as the site changes (for example, when analytics or advertising is actually enabled — see the privacy policy). The date at the top of this page reflects the most recent update.
