Terms of use

Last updated: May 3, 2026

Agreement to terms

Before using any Live Sudoku products, services, or websites, please read these Terms of Use (these "Terms") carefully. By using this website and its affiliated sites, you agree that these Terms constitute a legally binding agreement between the user ("User", "you", or "your"), whether personally or on behalf of an entity, and Live Sudoku, operated by Yotamix LTD ("Live Sudoku", "we", "us", or "our") (together, the "Parties"). A User is any person or entity who visits a Live Sudoku website, plays our web games, creates an account, or otherwise interacts with our service. We provide a web-based puzzle gaming service (the "Service"). These Terms govern your access and use of our websites and Service, including www.livesudoku.com and any localized version (such as the Spanish, Hebrew, Dutch, Polish, Italian, German, French, Portuguese, Finnish, Swedish, or Bulgarian editions), as well as any other media form, media channel, mobile website, or mobile application linked or otherwise connected to it (collectively, this "Site").

YOU AGREE THAT BY ACCESSING THIS SITE OR SERVICE, YOU HAVE READ, UNDERSTOOD, AND AGREED TO BE BOUND BY ALL OF THESE TERMS AND ALL APPLICABLE LAWS AND REGULATIONS. THESE TERMS REMAIN IN FULL FORCE AND EFFECT WHILE YOU USE THE SITE AND SERVICE. IF YOU DO NOT AGREE WITH ALL OF THESE TERMS, YOU ARE EXPRESSLY PROHIBITED FROM USING THE SITE AND MUST DISCONTINUE USE IMMEDIATELY.

Live Sudoku is intended to be enjoyed by players of all ages, and casual play (including live multiplayer matches) does not require an account. However, to register an account or submit content (such as guestbook posts, profile information, or messages), you must be at least the age of digital consent in your country (generally 13 in the United States, and 16 in much of the European Union), or have the involvement and consent of a parent or legal guardian. By creating an account, you affirm that you meet this requirement. We do not knowingly collect personal information from children below this age without verifiable parental consent, and if we become aware that we have, we will delete the information promptly.

Changes to terms of use

Supplemental terms and conditions, policies, procedures, or documents that may be posted on this Site from time to time are hereby expressly incorporated by reference and form part of these Terms. We reserve the right, in our sole discretion, to make changes or modifications to these Terms at any time and for any reason.

We will alert you about material changes by updating the "Last updated" date of these Terms, and you waive any right to receive specific notice of each such change. You are responsible for periodically reviewing these Terms to stay informed of updates. By continuing to use the Site after revised Terms have been posted, you accept the revised Terms. The information provided on the Site is not intended for distribution to or use by any person or entity in any jurisdiction or country where such distribution or use would be contrary to law or regulation, or which would subject us to any registration requirement within such jurisdiction or country. Anyone who chooses to access the Site from such locations does so on their own initiative and is solely responsible for compliance with local law.

Privacy policy

The information collected by Live Sudoku through your use of the Site and Service is governed by our Privacy Policy. Our Privacy Policy explains how we gather, use, and protect the information you provide, as well as your rights and our obligations regarding that data. For details, please review our Privacy Policy.

We use third-party analytics tools (such as Google Analytics) and may use third-party advertising and consent-management services that set cookies or similar technologies on your device. Where required by law (such as under the EU/UK GDPR, the UK Data Protection Act, and the California Consumer Privacy Act/CPRA), you have rights to access, correct, delete, port, or restrict the processing of your personal information. Requests can be made through the contact details at the end of these Terms.

Intellectual property rights

Unless otherwise indicated, the Site and Service are our proprietary property. All source code, databases, functionality, software, website designs, audio, video, text, photographs, puzzles, and graphics on the Site (collectively, the "Content"), and the trademarks, service marks, and logos contained therein (the "Marks"), are owned or controlled by us, or licensed to us, and are protected by copyright and trademark laws and various other intellectual-property and unfair-competition laws of Israel, the United States, the European Union, and international conventions. The Content and the Marks are provided on the Site "AS IS" for your information and personal use only. Except as expressly provided in these Terms, no part of the Site and no Content or Marks may be copied, reproduced, aggregated, republished, uploaded, posted, publicly displayed, encoded, translated, transmitted, distributed, sold, licensed, or otherwise exploited for any commercial purpose whatsoever, without our express prior written permission.

Provided you are eligible to use the Site, Live Sudoku grants you a non-exclusive, limited, non-sublicensable, and non-transferable license to access and use the Site and Service, and to download or print a copy of any portion of the Content to which you have properly gained access, solely for your personal, non-commercial use. All rights, titles, and interests in the Site, Service, Content, and associated intellectual property are reserved by Live Sudoku. Nothing in these Terms prevents Live Sudoku from providing the Service to others, and no rights are granted beyond those expressly stated. You agree not to reproduce, duplicate, copy, sell, resell, or otherwise exploit any part of the Site or Service, including visual design elements or puzzles, without express written consent.

If you wish to use Live Sudoku puzzles elsewhere — on a website, in print, in a book, or in any other product — please contact us first. We are usually happy to grant permission for non-commercial and educational use.

User representations

By using the Site and Service, you represent and warrant that:
  • you have the legal capacity and you agree to comply with these Terms;

User accounts

Some features of the Site — including saving progress, accessing the Hall of Fame, customizing your profile, and posting in the Guestbook — require a Live Sudoku account. You may register directly with Live Sudoku, or sign in through a supported third-party identity provider (such as Facebook). You are responsible for maintaining the confidentiality of your password and for all activity that occurs under your account. Notify us immediately if you believe your account has been accessed without authorization. We reserve the right to reclaim usernames that impersonate other people, infringe trademarks, or are otherwise inappropriate. You may close your account at any time by contacting us; closure does not relieve you of obligations incurred before the account was closed.

Live multiplayer and fair play

Live Sudoku offers real-time multiplayer matches between users. To keep matches fair and enjoyable for everyone, you agree that, in connection with the multiplayer service, you will not:
  • use any software, script, bot, automated solver, or external aid that solves or assists in solving puzzles on your behalf;
  • collude with other players, share solutions, or coordinate to manipulate match outcomes or rankings;
  • intentionally disconnect, lag-out, or otherwise disrupt matches to influence results;
  • impersonate another user, or maintain multiple accounts to abuse rankings, rewards, or matchmaking; or
  • harass, threaten, or behave abusively toward other players in lobbies, chats, or any related community feature.
We may, at our sole discretion, reset scores or statistics, void matches, suspend or close accounts, and take any other action we consider appropriate to enforce fair play.

Prohibited activities

  • you will not attempt to gain unauthorized access to any portion or feature of the Site, or to any other systems or networks connected to the Site, by hacking, password mining, or any other illegitimate means;
  • you will not probe, scan, or test the vulnerability of the Site or any network connected to it, nor breach the security or authentication measures on the Site;
  • you will not reverse-look-up, trace, or seek to trace any information about any other user or visitor of the Site; and
  • the Site and Service may not be used in connection with any commercial endeavor unless specifically endorsed or approved by us in writing.

User submissions and content

You acknowledge and agree that any postings, messages, text, files, images, photos, video, sounds, comments, suggestions, ideas, feedback, or other materials you provide on, transmit through, or link from the Service ("Submissions" or "Content") are the sole responsibility of the person from whom such Content originates. You will not use Live Sudoku to upload, transmit, retransmit, store, or distribute any Content that, in our sole discretion:
  • violates, attempts to violate, or helps any third party to violate any local, state, federal, or international law, ordinance, or regulation;
  • infringes any copyright, trademark, trade secret, or other proprietary right of any party;
  • is threatening, obscene, indecent, pornographic, abusive, harassing, libelous, defamatory, deceptive, fraudulent, or invasive of another's privacy, or that could otherwise adversely affect any individual, group, or entity;

  • victimizes, harasses, degrades, or intimidates an individual or group of individuals on the basis of religion, sex, sexual orientation, race, ethnicity, national origin, immigration status, age, disability, or any other reason.
Live Sudoku staff do not pre-screen user-submitted Content. We have the right, in our sole discretion, to remove any Content from our servers or from the Site at any time, with or without notice. You may not rely on the availability or accuracy of any Content uploaded by you or by any other user.

By submitting any Content to public areas of the Site (such as the Guestbook, your profile, or multiplayer chat), you grant Live Sudoku a non-exclusive, royalty-free, worldwide, perpetual license to use, display, reproduce, adapt, and distribute that Content in connection with operating and promoting the Site, in any media now known or later developed. With respect to any Submissions consisting of feedback, suggestions, or ideas about the Site or Service, you further agree that we may use them for any lawful purpose without compensation or attribution to you, and you waive any moral rights in such Submissions to the extent permitted by law. You warrant that any Submissions are original to you, or that you have all rights necessary to submit them, and that they do not infringe the rights of any third party.

Advertising and third-party services

The Site is supported by advertising. We may display ads served by third-party ad networks and exchanges, and we may use third-party services for analytics, consent management, login (such as Facebook Login), reCAPTCHA, hosting, and similar functions. These third parties may set cookies or similar technologies and collect information about your use of the Site as described in our Privacy Policy and in their own policies. Live Sudoku does not control, endorse, or assume responsibility for the products, services, content, or practices of any advertiser or third-party service. Any dealings you have with advertisers or third parties — including payment, delivery, and any terms, conditions, warranties, or representations associated with such dealings — are solely between you and that third party.

The Site may also contain links to third-party websites, including cross-promotional links to other Yotamix LTD properties. Such links are provided for your convenience and do not signify our endorsement of those websites. We have no responsibility for the content, accuracy, or availability of any linked third-party website.

Indemnification

You agree to defend, indemnify, and hold harmless Live Sudoku, Yotamix LTD, and our subsidiaries, affiliates, and our respective officers, agents, partners, and employees, from and against any loss, damage, liability, claim, or demand — including reasonable attorneys' fees and expenses — made by any third party due to or arising out of:
  • your use of the Site or Service;

Miscellaneous

These Terms, together with any policies or operating rules posted by us on the Site, constitute the entire agreement and understanding between you and us regarding the Site and Service. Our failure to exercise or enforce any right or provision of these Terms does not operate as a waiver of such right or provision. These Terms operate to the fullest extent permissible by law. We may assign any or all of our rights and obligations to others at any time. We will not be responsible or liable for any loss, damage, delay, or failure to act caused by any cause beyond our reasonable control. If any provision or part of a provision of these Terms is determined to be unlawful, void, or unenforceable, that provision or part of the provision is deemed severable from these Terms and does not affect the validity and enforceability of any remaining provisions. There is no joint venture, partnership, employment, or agency relationship created between you and Live Sudoku as a result of these Terms or your use of the Site and Service. You agree that these Terms will not be construed against us by virtue of having drafted them. You waive any defenses you may have based on the electronic form of these Terms or the lack of a hand-written signature.
