Terms of Service

Last updated: September 29, 2026

1. The short version

LogicPuzzle.io lets you play logic puzzles for free. Play as many as you like, for personal use. Don’t republish our puzzles at scale, don’t scrape or overload the site, and remember the puzzles are provided as-is with no warranty.

2. Using the service

You may use this site for personal, non-commercial entertainment and education. You may print puzzles for your own use or for a classroom, puzzle club or similar non-commercial setting, provided the LogicPuzzle.io attribution line printed on the sheet is retained. Automated scraping, bulk downloading, resale of the puzzles, or republishing substantial portions of the site or its puzzle archives is not permitted without written permission.

3. Intellectual property

The site design, puzzle generators, text and puzzle archives are the property of LogicPuzzle.io. Game formats themselves (nonograms, zebra puzzles, logic grids) are classic public puzzle styles that belong to everyone. We respect trademark owners’ rights: for example, "Picross" is a trademark of Nintendo and is used on this site only as a descriptive reference to that style of puzzle, never as a brand.

4. Availability and ads

The service is provided free of charge and on a best-effort basis. We may change, suspend or discontinue any part of it at any time. The site is supported by advertising; ad-free options, when offered, supplement but do not alter these terms. Daily puzzles and archives are generated material. While each puzzle is machine-verified for solvability, no guarantee is made that the service will be uninterrupted or error-free.

5. Limitation of liability

To the maximum extent permitted by law, LogicPuzzle.io is not liable for any indirect or consequential damages arising from your use of the site. If a puzzle ruins your sleep schedule because you stayed up for one more nonogram, that is on you.
