Purpose and availability
tinkerpuzzlerange.buzz provides independent informational and recreational puzzle content. The material is not an intelligence assessment, professional qualification or professional advice. We may correct, revise or remove content. We do not promise uninterrupted availability, a particular solving experience or a response to every message.
Practice tools and competition language
The home-page competition is an untimed local practice ladder. It has no entry fee, prize, account, public leaderboard or official ranking. Automated checks verify the entries specified by each exercise; they do not independently assess the quality of a written proof. The contact tool prepares a draft only. You must choose a separate email action to send it.
Fair and safe use
Do not misuse the site, interfere with its operation, attempt unauthorized access or use correspondence channels to send malicious, unlawful or infringing material. Do not submit unreleased competition problems that you are not permitted to share.
Matchstick exercises can be completed with drawings or unlit substitutes. Fictional escape-room content does not authorize opening a real lock, entering property, dismantling fittings or bypassing venue rules. Follow staff instructions and respect emergency exits. Never treat safety equipment or emergency procedures as a puzzle obstacle.
Intellectual property
Original editorial text, site design and other protected material remain subject to applicable intellectual-property rights. You may link to pages and use the site for personal study. Seek permission before substantial reproduction or redistribution, except where applicable law provides an exception. Third-party names, works and images may have separate rights; mentioning them does not grant permission to reproduce them.
Submitting a correction does not transfer ownership of your work. If we wish to publish a substantial contribution or attribution, permission and wording should be agreed separately. Checking the optional quotation box merely permits a discussion about that use.
Accuracy and limitations
We aim to state clear rules and defensible solutions, but errors and ambiguities may remain. Check important conclusions yourself and report counterexamples with the relevant contract. Content is provided as available, without a guarantee of completeness or suitability for a particular purpose.
To the extent permitted by applicable law, we are not responsible for losses arising from reliance on recreational content or interruption of the site. Nothing here excludes liability that cannot lawfully be excluded, limits mandatory consumer rights, or prevents a legal remedy available under applicable law.
Independence, links and questions
This site is not affiliated with puzzle publishers or competition organizers mentioned. References and external destinations are provided for context, not as a promise of endorsement or continued availability. Third-party services have their own terms.
Questions, permission requests and correction reports can be sent to [email protected]. See Privacy for information about local drafts and correspondence. Updates to these terms will be published on this page.
