Terms of Service

These Terms of Service apply to your use of Norinori Puzzle at norinoripuzzle.com. By using the site, you agree to these terms. If you do not agree, please stop using the service. Questions can be sent to support@norinoripuzzle.com.

Using Norinori Puzzle

Norinori Puzzle provides free browser-based Norinori logic puzzles and related guides. You may play for personal use and share links to puzzles and public pages. An account is not required for public play; access to older archive dates requires sign-in.

You must be able to agree to these terms under the law that applies to you. If you are a minor, use the service with the permission and guidance of a parent or guardian where required.

Daily sets, practice puzzles, timed challenges, and archive dates depend on service and content availability. We may update puzzles, correct errors, change features, or temporarily interrupt access for maintenance or security reasons.

Optional accounts

If you use Google sign-in, provide accurate account information and keep access to your Google account secure. Do not impersonate another person or use an account without permission. Contact us if you suspect unauthorised use of your Norinori Puzzle account.

Accounts do not provide cloud synchronisation of game progress. Saves are stored in your current browser when storage is available. We cannot guarantee recovery of saves lost through cleared storage, private browsing, device changes, or browser failures.

Fair and acceptable use

Do not:

• Attempt to access accounts, private data, or systems without permission.
• Disrupt the service, bypass security controls, overload its infrastructure, or send abusive automated requests.
• Submit unlawful, threatening, harassing, or deceptive material through feedback or contact channels.
• Use the site to distribute malware, spam, or material that infringes another person's rights.
• Misrepresent Norinori Puzzle as an official Nikoli service, or claim an endorsement that does not exist.

We may restrict access or suspend an account when reasonably necessary to address misuse, security risks, or legal obligations. You can contact us if you believe a restriction was made in error.

Content and puzzle links

Norinori Puzzle's original text, artwork, branding, and software are protected by applicable intellectual-property laws, subject to any relevant third-party or open-source licences. General puzzle ideas and third-party trademarks are not claimed as our exclusive property.

You are welcome to share puzzle links and screenshots of your play. These terms do not grant permission to reproduce the website as a competing service, redistribute its original content in bulk, or use Norinori Puzzle branding in a way that implies an official partnership. Any rights you have under applicable law remain unaffected.

Feedback and suggestions

Only submit messages and attachments that you have the right to share. You retain your rights in what you submit and allow us to use it as needed to review your request, respond, investigate issues, and improve the service. Submitting feedback does not transfer ownership of your personal information or authorise its public disclosure.

Please do not include credentials, private information about other people, or material unrelated to your request. See our Privacy Policy for how submissions and account information are handled.

Third-party services and independence

Norinori Puzzle is independent of Nikoli and is not affiliated with, sponsored by, or endorsed by Nikoli. Our daily sets are generated for this website. Third-party names and trademarks belong to their respective owners.

The website may include advertising and links to external websites. Those services have their own terms and policies. An advertisement or external link does not mean we endorse the provider, and we do not control purchases or other arrangements you make with them.

Availability and limitations

We aim to provide a useful, enjoyable puzzle service, but do not promise uninterrupted access, error-free puzzles or guides, permanent availability of any specific board, or preservation of browser saves. Timers and game results are for entertainment and do not carry prizes or financial value.

To the extent permitted by applicable law, the service is provided as available, without additional guarantees of fitness for a particular purpose. We are not responsible for indirect or consequential losses caused by use of, or inability to use, the service where the law permits that limitation. Nothing in these terms excludes liability or limits consumer rights that cannot lawfully be excluded or limited.

Changes and contact

We may revise these terms as the service changes. Updated terms will be posted here with a revised date; changes apply prospectively, subject to any notice required by law. If you no longer wish to use the service, you may stop at any time and contact us about your account or personal information.
