Terms of Use

Last updated: May 15, 2026

These Terms of Use ("Terms") govern your access to and use of Knotwise Games, including the website, the daily puzzles, the archive, paid subscriptions, and any related features (collectively, the "Services"). By accessing or using the Services, you agree to be bound by these Terms. If you do not agree, do not use the Services.

1. Parties and definitions

Knotwise Games ("Knotwise", "we", "us", "our") is an independent puzzle studio. "Services" means the Knotwise Games website together with the daily puzzles, archive, account features, and subscriptions offered through it. "You" or "User" means any individual who accesses or uses the Services.

For any matter relating to these Terms, contact us at contact@knotwise.games.

2. Eligibility and accounts

You may play the current day's puzzle without an account. Use of any other feature — including the archive, paid subscriptions, and cross-device progress sync — requires you to register an account.

To register an account you must be at least 13 years of age, or the higher minimum age of digital consent applicable in your jurisdiction (for example, 16 in much of the European Economic Area and the United Kingdom). If you are under the age of majority where you reside, you may use the Services only with the involvement of a parent or guardian.

You agree to provide accurate registration information, to keep your credentials confidential, and to be responsible for activity that occurs on your account. You must notify Knotwise promptly of any unauthorised use of your account.

3. License grant; changes to the Services

Subject to your compliance with these Terms, Knotwise grants you a limited, personal, non-exclusive, non-transferable, non-commercial, revocable license to access and use the Services as offered, including to solve puzzles, browse the archive consistent with your subscription tier, sync progress to your account, and share your own solve results with others. This license does not include any right to commercial use, resale, or redistribution of the Services or to incorporate the Services into another product.

Knotwise may modify, suspend, or discontinue any portion of the Services at its discretion, including by adding or removing features, redesigning components, adjusting prices, or limiting availability in particular regions. Where a change materially reduces a paid feature you have already subscribed to, Knotwise will provide reasonable advance notice.

4. Prohibited conduct

You agree not to, and not to permit any third party to:

• violate applicable law or the rights of any third party in connection with the Services;
• scrape, crawl, mass-download, reverse-engineer, decompile, or disassemble any portion of the Services, including puzzles, solutions, or source code;
• circumvent any paywall, rate limit, authentication mechanism, or other access control;
• harass, threaten, defame, or impersonate any User; upload or transmit malicious code, malware, or harmful content;
• use bots, scripts, or other automated means to create accounts, play puzzles, generate traffic, or extract data from the Services;
• interfere with or disrupt the integrity, security, or performance of the Services.

Violations may result in suspension or termination of your account under Section 9, and Knotwise may report unlawful activity to the relevant authorities.

5. Intellectual property and feedback

All content within the Services — including puzzles, solutions, illustrations, source code, trademarks, logos, and copy — is owned by Knotwise or its licensors and is protected by applicable intellectual property laws. No rights are granted to you other than the limited license described in Section 3.

You may share your own solve experience (for example, a completion image or score) for personal, non-commercial purposes. You may not republish, syndicate, sublicense, or otherwise redistribute Knotwise puzzles or their solutions, in whole or in part, on any other platform.

If you submit feedback, suggestions, bug reports, or other input to Knotwise, you grant Knotwise a perpetual, irrevocable, royalty-free, worldwide, sublicensable license to use, modify, and incorporate that input into the Services or related materials. Knotwise has no obligation to act on any specific submission or to credit the contributor.

6. Subscriptions, billing, and renewals

Certain features of the Services, including paid subscriptions, require payment. By initiating a subscription you agree to pay the price displayed at checkout, together with any applicable taxes and fees.

Subscriptions automatically renew at the end of each billing cycle until cancelled. You may cancel at any time from your account settings; cancellation takes effect at the end of the current paid period, and you retain access to subscriber features until then. Except where required by applicable law, fees are non-refundable and no pro-rated refunds are issued for partial billing cycles.

Knotwise may change subscription prices on a prospective basis. Material price changes will be communicated with reasonable advance notice, and you may cancel before the new price takes effect.

Payments are processed by Stripe. Stripe's terms of service and privacy policy govern its payment-processing services and are independent of these Terms.

7. Third-party services

The Services may integrate with, link to, or display content from third-party services, including payment processors, analytics providers, OAuth identity providers, and social platforms. Knotwise does not control these third parties, and your use of them is governed by their own terms and privacy policies. Knotwise disclaims responsibility for the availability, content, accuracy, or data-handling practices of any third-party service.

8. Disclaimers, limitation of liability, and indemnification

Disclaimer of warranties. THE SERVICES ARE PROVIDED ON AN "AS IS" AND "AS AVAILABLE" BASIS. KNOTWISE DOES NOT WARRANT THAT THE SERVICES WILL BE UNINTERRUPTED, ERROR-FREE, SECURE, OR COMPATIBLE WITH ANY PARTICULAR DEVICE OR SOFTWARE. TO THE MAXIMUM EXTENT PERMITTED BY APPLICABLE LAW, KNOTWISE DISCLAIMS ALL WARRANTIES, EXPRESS OR IMPLIED, INCLUDING WARRANTIES OF MERCHANTABILITY, FITNESS FOR A PARTICULAR PURPOSE, AND NON-INFRINGEMENT.

Limitation of liability. TO THE MAXIMUM EXTENT PERMITTED BY APPLICABLE LAW, KNOTWISE'S TOTAL AGGREGATE LIABILITY ARISING OUT OF OR RELATING TO THESE TERMS OR THE SERVICES IS LIMITED TO THE GREATER OF (A) THE AMOUNTS YOU PAID TO KNOTWISE IN THE TWELVE MONTHS PRECEDING THE EVENT GIVING RISE TO THE CLAIM, OR (B) US$50. KNOTWISE WILL NOT BE LIABLE FOR ANY INDIRECT, INCIDENTAL, CONSEQUENTIAL, SPECIAL, EXEMPLARY, OR PUNITIVE DAMAGES, EVEN IF ADVISED OF THE POSSIBILITY OF SUCH DAMAGES. Some jurisdictions do not allow the exclusion or limitation of certain damages; in those jurisdictions Knotwise's liability is limited to the maximum extent permitted by law.

Indemnification. You agree to defend, indemnify, and hold harmless Knotwise, its affiliates, and its personnel from and against any claim, liability, loss, damage, or expense (including reasonable legal fees) arising from or related to your use of the Services, your breach of these Terms, or your violation of any right of a third party.

9. Suspension and termination

You may stop using the Services and close your account at any time.

Knotwise may suspend or terminate your account, or restrict your access to the Services, if we reasonably believe you have breached these Terms or if required by applicable law. Following account closure, your account data is removed from our live systems within a commercially reasonable window; see the Privacy Policy for specific retention practices.

The following provisions survive termination: Section 5 (Intellectual property and feedback), Section 8 (Disclaimers, limitation of liability, and indemnification), and Section 10 (Miscellaneous provisions), together with any other provisions that by their nature should survive.

10. Miscellaneous provisions

Entire agreement. These Terms constitute the entire agreement between you and Knotwise concerning the Services and supersede any prior agreement on the same subject.

Severability. If any provision of these Terms is held to be invalid or unenforceable, the remaining provisions remain in full force and effect.

No waiver. Knotwise's failure to enforce any provision of these Terms does not waive its right to enforce that provision in the future.

Assignment. You may not assign or transfer your rights under these Terms without Knotwise's prior written consent. Knotwise may assign these Terms in connection with a merger, acquisition, reorganisation, or sale of assets.

Updates. Knotwise may revise these Terms from time to time. Material changes will be communicated through the Services or by email, and the "Last updated" date above will reflect the most recent revision. Your continued use of the Services after the effective date of a revision constitutes acceptance of the updated Terms.
