Terms of service

Last updated: 8 October 2026. By using Queenwise you accept these terms.

The service

Queenwise offers free solo puzzles and optional account-based cloud saves, daily time trials, and multiplayer competition. Solo progress is stored in your browser; connected saves and competitive records also use our server. We may add, change, or remove puzzles, features, or the service itself at any time, without notice.

Your content

Puzzle progress, marks, and settings live in your browser and belong to you. The puzzles, explanations, diagrams, and text on this site are the property of the site operator and may not be reproduced commercially without permission.

Acceptable use

You may play Queenwise for personal, non-commercial use. Do not attempt to disrupt, scrape at abusive volume, use automated solvers in competitive play, or misrepresent the service. Keep your password and recovery code private. Server validation checks completed boards and timing; it does not guarantee detection of every form of assistance.

No warranty

The service is provided “as is”. While every published puzzle is verified to have exactly one solution, we do not warrant that the service will be uninterrupted or error-free. To the extent permitted by law, we are not liable for any loss arising from use of the service.

Changes

We may update these terms; the date above reflects the latest revision. Continued use after a change constitutes acceptance.
