Play fair.
Know the rules.

The service is operated by Hamilton Digital Media Limited (“we”, “us” or “our”), a private limited company registered in England and Wales under company number 15608219.

By using the service, you agree to follow these terms. If you do not agree, please do not use the service. If you are not old enough to agree to these terms under the law where you live, use the service only with permission from a parent or guardian.

Anyone under 13 should ask a parent or guardian before emailing us or sending personal information.

Puzzle Workout is a free recreational puzzle and brain-training website. It currently provides standalone games, a date-based five-game Daily Brain Workout, explanatory articles and a progress dashboard. You do not need to create an account or pay to use these features.

The exercises and scores are for entertainment and personal progress. They are not medical, psychological, educational or professional assessments; they do not diagnose a condition or measure intelligence or neurological health. Do not use them as a substitute for professional advice.

We give you a personal, non-exclusive, non-transferable and revocable permission to access and use the service for lawful, non-commercial recreation, subject to these terms.

You may:

• play the games and use the progress features for personal purposes;
• link to public Puzzle Workout pages;
• share your own scores, share text and screenshots of your own result screens; and
• use ordinary browser accessibility, translation and personal-assistance tools.

You must not:

• break the law, infringe another person’s rights, or use the service to harm, threaten or deceive anyone;
• interfere with the service, bypass security or access controls, introduce malicious code, or attempt unauthorised access;
• send automated requests at a volume that could impair the service or impose an unreasonable load;
• systematically extract, mirror, frame or republish substantial parts of the games, question supply, articles, designs or code;
• use a substantial collection of our content to build, train, evaluate or supply another product or automated system without written permission; or
• remove ownership notices or suggest that we endorse, sponsor or operate another service when we do not.

Conventional search engines may crawl and index public pages in accordance with our technical instructions. That permission does not extend to republishing the service, harvesting the puzzle supply or using scraped material as a substitute product.

We may restrict access where reasonably necessary to protect the service, other users or our rights, or to respond to unlawful or materially abusive use.

Many Puzzle Workout questions are created automatically from deterministic seeds and checked against game-specific rules. The Daily Brain Workout uses the date on your device so players on the same local date normally receive the same seeded workout. Incorrect device time, browser behaviour, software updates or different game versions can affect that experience.

We take reasonable steps to validate generated puzzles, answer options and scoring. Automated generation and software are not infallible, so a question, explanation, score or difficulty label can occasionally be wrong. Please report a suspected error through the Contact page with the page, date, difficulty and what happened.

Scores depend on the game, difficulty, accuracy, timing, completed questions and the scoring version in use. The first eligible completion can be treated as the official Daily result for that local date. Practice attempts, pauses, device performance and input method can make results differ.

Scores, personal bests, averages, streaks and comparisons have no cash value, do not create a right to a prize, and are not a certified ranking. We may correct a clear scoring or puzzle error and may revise generation, difficulty or scoring methods for future play. We will not deliberately rewrite a locally saved result, although a newer site version may display or compare historical data differently.

Workout history is stored in a first-party IndexedDB database in your browser. It is not attached to an account, synchronised to our servers or automatically copied to another browser or device. We cannot view, restore or merge it for you.

You can export or reset the current browser’s Puzzle Workout data from the Progress page. Clearing site data, private browsing, browser settings, storage eviction, a reset, device loss or a browser failure may remove or isolate progress. An export is your own copy; the current service does not import it.

Share and copy controls act only after you select them. You are responsible for reviewing the score text or screenshot before sharing it and for choosing where it goes. More detail appears in our Cookies and Local Storage page.

The service’s original text, visual design, game interfaces, puzzle systems, software, branding and other materials are owned by or licensed to Hamilton Digital Media Limited and are protected by applicable intellectual-property laws. These terms give you permission to use the service; they do not transfer ownership of it.

The permissions in section 3 cover ordinary personal score sharing and links. Any other reproduction, adaptation, distribution, commercial use or creation of a substitute service from our materials requires our prior written permission, unless the law independently allows it.

If you send feedback, corrections or suggestions, you keep any rights you already have in your original material. You give us a worldwide, non-exclusive, royalty-free permission to use, adapt and incorporate that material to operate and improve Puzzle Workout and related puzzle products. Do not send confidential material or anything you are not allowed to share. We are not required to use an idea, reply, credit you or pay compensation.

We use reasonable care to keep the service available and working, but we cannot promise continuous, secure or error-free access. We may fix, improve, replace, suspend or remove a game, article, feature or the service as a whole. Where reasonably possible, we will explain a material change on the site.

We may update these terms for a legal, security, technical or service change. The new version will show its effective date and will apply from that date, not retrospectively. If you do not agree to an updated version, stop using the service.

Some pages link to websites operated by other organisations. A link does not mean we control or endorse the outside site. Its content, availability, security, privacy practices and terms are the responsibility of its operator. Check them before relying on the site or giving it information.

Nothing in these terms excludes or limits responsibility where doing so would be unlawful. This includes responsibility for death or personal injury caused by negligence, fraud or fraudulent misrepresentation, and your mandatory rights under consumer law.

If we fail to comply with these terms or fail to use reasonable care and skill, we are responsible for loss or damage that is a foreseeable result of that failure. Loss or damage is foreseeable if it was obvious that it would happen or both you and we knew it might happen when you began using the service. We are not responsible for loss or damage that was not foreseeable.

The service is supplied for private, recreational use. If you use it for a business or commercial purpose, we are not responsible for business losses, including loss of profit, revenue, opportunity, anticipated savings, goodwill or business data.

We are not responsible for lost local progress caused by clearing browser data, private-browsing behaviour, browser storage eviction, a user-requested reset, device loss or a failure outside our reasonable control, unless the loss also results from our failure to use reasonable care and skill.

Please send a service or terms complaint to [email protected]. Include enough detail for us to understand the issue and the outcome you are seeking. Privacy complaints follow the process described in the Privacy notice.

These terms and your use of the service are governed by English law, but you keep any mandatory protection given by the law of the country where you live.

If you are a consumer living in England or Wales, the courts of England and Wales have jurisdiction. If you live in Scotland, Northern Ireland or another country, you may bring proceedings in your local courts where applicable consumer law permits.

Each section of these terms operates separately. If a court or relevant authority decides that one part is unlawful or unenforceable, the other parts continue to apply. A delay in enforcing a term is not a waiver of the right to enforce it later. No person other than you and Hamilton Digital Media Limited has a right to enforce these terms.
