Terms and conditions

1.1. Buildner Minigames, including the website and games on which these Terms are expressly presented, is operated by BUILDNER, SLU, a company established under the laws of the Principality of Andorra, registration number 715322-T, with its registered address at Carretera Mas de Ribafeta 6, 3-1, Arinsal, La Massana, AD400, Andorra. In these Terms, we, us, and our mean BUILDNER, SLU. Our contact email is contact@buildner.com.

1.2. These Terms apply to the minigames collection, its individual games, puzzles, instructions, illustrative content, scores, guest identities, saved progress, rankings and reporting features, together the Service. Each individual game is a Game. A Game may be hosted on a separate page or domain; these Terms apply where it is identified as part of this Service and these Terms are made available to you.

1.3. The current collection comprises Brief Encounter, Load-Bearing Ego, Something’s Off, Site Visit and Permit Pending, where available. The game-specific schedule at the end forms part of these Terms. It explains the purpose and limitations of each Game; the instructions displayed in the Game explain its current rules.

1.4. Buildner architecture competitions, Architecture Tools, BIM Tools, courses, subscriptions, publications and other offerings have their own terms. Using a Game does not register you for a competition, create a subscription to another service, or change an existing contract. Shared ownership, branding, links or sign-in do not combine those offerings into one service.

1.5. The privacy notice made available for this Service separately explains personal-data processing. These Terms are not a privacy policy or consent to optional tracking, marketing, or unrelated use of your information. Any consent required by law must be obtained separately.

1.6. Provisions about accounts, profiles, paid access, prizes or other additional features apply only if we expressly offer the feature and you use it. They do not mean those features currently exist or promise their introduction. More specific terms must be clearly identified before they apply. Mandatory legal rights always take priority.

2.1. By selecting an acceptance control, or using the Service after clear notice of these Terms and a reasonable opportunity to read them, you agree to them to the extent a binding agreement can be formed in that way under applicable law. If you do not agree, do not use the Service.

2.2. The Service is intended for adult architecture and design students, educators, professionals and other adults who enjoy architectural puzzles. You do not need a professional qualification to play. You must be at least 18 years old and legally capable of entering this agreement. The Service is not offered for independent use by children.

2.3. If you use the Service on behalf of a business, practice, institution or other organisation, you confirm that you have authority to accept these Terms for it. References to you include that organisation where appropriate. Do not accept on its behalf if you lack that authority.

2.4. A Consumer is a person entitled to consumer protection under applicable law. A Business User acts for purposes relating to a trade, business, craft, profession or institutional activity and is not entitled to consumer treatment for that use. Status depends on the circumstances and law, not merely on a label, your occupation or your possession of a professional qualification.

2.5. Where an entry notice is presented, complete its required acknowledgements before entering the protected parts of the Service. The Terms and privacy information remain available to read before acceptance. Remembering an acknowledgement in your browser does not create a player profile, verify your age or identity, or give consent to optional tracking or marketing.

3.1. The Games are recreational puzzles. They simplify spatial planning, balance, visual patterns, route finding and rule-based decisions to create a playable challenge. Fictional clients, briefs, proposals, approvals, dimensions, buildings and comments are part of that experience.

3.2. A Game does not provide architectural, engineering, planning, building-control, legal, fire-safety, accessibility or other professional advice. It does not establish compliance with a building code, planning rule, competition brief or professional standard, and it does not replace a qualified professional’s assessment.

3.3. A stable cantilever in Load-Bearing Ego is not a safe structural design; a completed floor plan in Brief Encounter is not a buildable or compliant plan; a route in Site Visit is not an approved escape route; a correct stamp in Permit Pending is not a permit; and a successful round in Something’s Off is not a building inspection.

3.4. Scores, stars, points, ranks, praise and client remarks describe performance under the Game’s rules. They are not qualifications, professional accreditation, an assessment of your competence or a guarantee of success in academic work, employment or a Buildner competition. Do not present them as such.

3.5. Use appropriate professional processes for real projects. Nothing in this section removes our responsibility for a binding description of the Service or any obligation that applicable law places on us.

4.1. The current Games are free to play. You remain responsible for your own internet, device, software and other third-party costs.

4.2. We may introduce charges for future features, additional content, subscriptions or organisational licences. Free availability does not promise that every feature will remain free indefinitely. Any change remains subject to existing commitments and applicable law.

4.3. Before you incur a charge, we will clearly disclose the price, currency, applicable taxes, what is included and material purchase conditions. Subscription terms must explain duration, renewal and cancellation. Applicable withdrawal, refund and digital-service rights must also be explained before purchase.

4.4. Playing a free Game does not authorise payment, create a paid subscription or permit us to charge a payment method used with another Buildner service. We will not charge retrospectively for play that was free. Moving to a paid offering requires your express agreement to that purchase.

4.5. If you do not agree to paid access, you may stop using the affected feature and continue using any free functions that remain available. Introducing charges does not, by itself, revoke the permissions in section 14 for screenshots or recordings lawfully made earlier.

5.1. Subject to these Terms, we grant you a limited, non-exclusive, non-transferable permission to access and play the Games through their intended interfaces for lawful personal recreation and educational use, including informal use within a practice or adult classroom.

5.2. You may link to the Service and discuss it. Screenshots and recordings are covered by section 14. Browser caching, accessibility functions and other acts necessarily incidental to permitted play are allowed.

5.3. This permission does not include copying, hosting, sublicensing, reselling, embedding or distributing the Games as your own product or service. Operating a paid event, commercial game service or white-label version requires a separate written agreement. Charging for teaching does not itself authorise you to reproduce or resell a Game.

5.4. Rights granted by applicable law or a valid separate open-source licence remain unaffected. You may keep a copy of these Terms for your records.

6.1. Follow the instructions displayed for the relevant Game, mode and version. A result may depend on completion, accuracy, moves, hints, active play time, a stable placement, a particular challenge or other disclosed factors. Different Games need not use the same scale or formula.

6.2. A preview, incomplete attempt or browser-displayed result is not necessarily an eligible saved score. Some Games require an explicit finish or save action; others submit an eligible run automatically when it ends. Check the Game’s completion and save messages.

6.3. Where supported, you may replay, restart, undo, pause or use hints through the normal controls. These are not cheating merely because they are available. Their effect on the score depends on the Game’s stated rules. Restarting or leaving a Game may discard an unfinished attempt.

6.4. Network interruptions, unavailable storage, unsupported browsers or validation failures may prevent a result from being saved. A pending submission or retry message does not confirm that the server accepted it. Use any retry control provided and retain the page when instructed.

6.5. We may correct mistakes in a rule, score calculation or displayed result. A material scoring change should be identified by a new version, separate ranking group or a clear explanation of its effect. We will not knowingly present results produced under materially different rules as directly comparable without explaining the comparison.

7.1. Scores and rankings are informal features for enjoyment and comparison. They have no cash value, cannot be redeemed or transferred for payment, and do not create ownership of a leaderboard position or an entitlement to a prize, discount, competition entry or other benefit.

7.2. Ranking availability varies by Game. A board may rank individual runs, one best result per guest, or the best results across a stated set of challenges. The Game’s ranking information explains the applicable method. There is no promise of one combined score or shared player identity across all Games.

7.3. Scores are comparable only within the relevant rules, version, mode, challenge set and ranking period. Equal displayed totals do not necessarily mean equal rank where the Game discloses tie-breaking criteria. A chronological display order within a tie does not itself resolve the tie.

7.4. A shared board may display a generated guest label or run identifier, points, position, completion details and other performance information described in the Game. It may show only a limited number of entries. Do not assume a shared result is visible only to you; review the relevant ranking information before completing or submitting a run.

7.5. Server-side calculation and checks may reject invalid, duplicate or unsupported submissions. Passing those checks does not certify identity, confirm unaided human play or prove that a result is free from manipulation. Current guest rankings are not verified professional or prize competitions.

7.6. We may correct, exclude or remove a result when reasonably necessary to address an error, duplicate, incompatible rules version, manipulation, unlawful content or a material breach. We may also archive a board or introduce a clearly identified new season or version. Restrictions and review rights are addressed in section 19; applicable legal rights remain unaffected.

7.7. We do not guarantee a permanent position, permanent display of a run, or recovery of an unsaved result. This is not an exclusion of responsibility for our own breach or a right to disregard a specific paid or promotional commitment.

8.1. Some Games recognise a browser using a guest identifier or cookie and store progress or scores on the server. Others keep results only for the current page session or store limited progress or pending submissions in the browser. A Game’s current interface and privacy information explain the relevant behaviour; not every Game provides all these functions.

8.2. A guest session is not necessarily a registered account. Clearing cookies or site data, using private browsing, switching browser profiles or devices, or changing the Game’s website address can break the link to guest records or remove local progress. Blocking required storage may prevent saving or restoring a session.

8.3. Clearing local storage does not necessarily delete a score or progress record already received by the server. A new guest identity does not automatically establish ownership of old results. Where a recovery or linking feature is absent, we may be unable to restore access or combine histories.

8.4. On a shared browser or device, another person may be able to continue the recognised guest session or view its progress. Use the available browser and account controls appropriately. Do not share session credentials or identifiers that enable access to someone’s private information.

8.5. Saving progress is a convenience, not a promise of indefinite storage, cross-device synchronisation or guaranteed recovery. We will handle personal data under the applicable privacy notice and law. Contact us if you need assistance with a stored record; proportionate verification may be necessary before we change or disclose it.

9.1. This section applies only where an account, sign-in, profile or account-linking feature is expressly offered. A hosting platform may separately require sign-in to view a page; that does not automatically create a Buildner Minigames profile or merge guest histories.

9.2. Provide accurate information where required for account operation or eligibility. Do not impersonate another person, misrepresent your age or authority, or claim a qualification that you do not hold. Keep required contact and recovery details reasonably up to date.

9.3. Protect passwords, authentication codes, sign-in links and connected sign-in methods. Tell us promptly if you suspect unauthorised access and take reasonable steps to secure the account. You are responsible for activity you authorise and, where the law provides, activity caused by your failure to take reasonable care. You are not automatically liable for every action through a compromised account or for a security failure for which we are responsible.

9.4. Use only accounts you are entitled to access. Do not sell or rent access, share personal credentials to evade restrictions, or claim another person’s results. Linking guest results to an account requires the available ownership-verification process; a matching display name is not proof.

9.5. We will explain what a profile makes visible before you use its public features. Creating an account does not itself permit publication of private information, use of your identity in advertising, or charging you for another service. Closure and personal-data requests remain subject to the applicable privacy notice and law.

10.1. Play through the intended controls and submit results that accurately reflect your own permitted play. Do not falsify scores, completion events, move histories, timings, identities or server requests, alter stored records without authorisation, or exploit a defect to obtain or preserve an improper ranking advantage.

10.2. Do not use bots, scripts, automated solvers, macros or modified clients to manufacture ranked results or evade a stated challenge rule. Do not deliberately create multiple identities to manipulate a board, bypass a suspension or obtain a benefit dishonestly. Normal retries, in-game hints and legitimate assistive technology are allowed unless a specific competitive format lawfully requires and clearly explains different conditions. Accessibility tools are not prohibited merely because they automate an input action.

10.3. Do not access another user’s session or private records, circumvent security or access controls, introduce malicious code, interfere with the Service, overload it or probe systems without authorisation. A public interface or visible source code does not grant permission to disrupt or exploit the Service.

10.4. Do not use any profile, name, report or other feature to harass, threaten, impersonate, distribute unlawful material, infringe rights or disclose someone else’s private information. Do not submit knowingly false reports or use reporting controls to target another player.

10.5. Do not systematically extract protected Game content, copy the Service as a substitute product, remove rights notices or misrepresent your connection to Buildner. Restrictions on reverse engineering, interoperability, research or similar activity apply only to the extent permitted by law; non-excludable statutory rights remain available.

10.6. Finding a defect does not authorise further harmful testing. Stop activity that risks damage or unauthorised access and report the issue privately to contact@buildner.com. We do not promise a bounty or authorise security testing merely because a reporting address is provided.

11.1. Your Content means original material you provide through an available feature, such as a report, feedback, profile description, chosen display name or shared material. It does not include our underlying game code, artwork or interface. You retain the rights you already hold in Your Content.

11.2. Provide only material you are entitled to use and disclose. Do not include confidential client work, another person’s private information, passwords, payment-card details, identity documents or unrelated sensitive information in an error report or other free-text field.

11.3. To the extent a licence is required, you give us a non-exclusive, worldwide, royalty-free permission to receive, store, reproduce, technically adapt, transmit and display Your Content only as reasonably necessary to provide the feature you use, display material you choose to make public, provide requested support, protect the Service and comply with law. We may extend that limited permission to providers performing those functions for us.

11.4. That permission does not authorise us to sell Your Content, use your identity or private material in advertising, or train a general-purpose AI model on it. Additional uses require a separate lawful basis and any legally required licence or consent. Worldwide technical operation does not override applicable restrictions on international transfers of personal data.

11.5. The permission lasts only for the relevant service, support, security and legal purposes, including a limited period needed to complete lawful retention or deletion. The privacy notice governs personal-data handling. Nothing here gives us a general right to exploit your material after those purposes end.

12.1. Playing may produce moves, answers, timings, completion records, scores and diagnostic information. Where saving or ranking is part of the feature, relevant data may be transmitted to us or our service providers to calculate, validate, save and display the result. The fact that a Game runs in your browser does not mean all related activity stays on your device.

12.2. The error-reporting feature explains what is included before you submit. This may include a short note, page address, time, browser information and recent technical errors. Submit only the information reasonably needed to explain the issue. Use our contact address for a matter requiring a reply or material beyond the form’s limits.

12.3. Personal-data purposes, legal bases, retention, providers, transfers and rights are addressed in the separate privacy notice. These Terms do not substitute for that notice, waive data-protection rights or make optional marketing or tracking a condition of accepting the Terms.

12.4. Operational communications concerning security, an account, a reported problem or an important service change do not themselves authorise unrelated marketing.

13.1. You need a compatible browser and device. Saving, shared rankings, loading assets and other online functions may require an internet connection. We do not promise that every Game supports every browser, input method, screen size, offline mode or assistive technology; binding descriptions and applicable accessibility obligations remain unaffected.

13.2. Browser performance, zoom, orientation, input devices, connection quality and interruptions can affect the experience and, where timing matters, a result. A pause in one Game may not pause a different Game’s timing or preserve an unfinished run.

13.3. Play in a suitable setting, take breaks when needed and stop if you experience discomfort. Do not play while driving, operating machinery or doing another activity requiring your attention. This guidance does not transfer responsibility for our own breach or negligence to you.

13.4. Do not use the Service as your only record of an achievement or important material. Where a download or sharing feature is available, keep your own permitted copy if you need it. Availability, retention and remedies remain subject to the commitments and protections in these Terms and applicable law.

14.1. The Service’s software, game mechanics to the extent legally protected, interface, puzzles, text, graphics, illustrations, sound, branding and other materials belong to us or our licensors. Except for the permissions expressly granted here or by law, no ownership or other licence is transferred to you.

14.2. You may share screenshots and short recordings of your own lawful play for personal discussion, criticism, review and teaching. Keep any visible attribution or copyright notices, respect other people’s privacy and do not imply Buildner endorses you. Statutory quotation and other applicable exceptions remain unaffected.

14.3. This permission does not allow extraction or resale of artwork, puzzle collections, software or other assets as standalone products, replication of the Games, or use of our marks to brand your own product. Ask for permission before a use beyond the licence in these Terms, unless the law independently permits it.

14.4. You may describe your result accurately and link to the Service. Do not pass an edited screenshot off as an authentic ranking or present a Game result as a professional approval, qualification or competition award. A link must not falsely imply partnership, sponsorship or official status.

14.5. Third-party and open-source components remain subject to their applicable licences. These Terms do not reduce rights validly granted by those licences.

15.1. Ordinary play does not involve a wager or an offer of a prize. Points, ranks and virtual achievements are features of the Games, not money or transferable assets. A reference to Buildner competitions is not entry into one.

15.2. If we offer a prize challenge, tournament or promotion, we will provide separate rules before participation. Those rules must identify the organiser, eligibility, territory, entry method, dates, scoring and verification, tie-breaks, prizes and material conditions. A promotion exists only when we expressly announce it with its rules; a high score alone is not an offer.

15.3. Informal guest scores do not automatically qualify for a promotion. Its rules will explain whether an existing result is eligible and what verification is required. We will not retrospectively impose new material entry requirements contrary to an existing commitment or applicable law.

15.4. A third-party event using or referring to a Game is not organised or endorsed by us merely because it mentions Buildner. Any use requiring our permission remains subject to section 5.

16.1. The Service may link to separate Buildner offerings or independent websites and platforms. Their own terms and privacy notices apply to those services. We do not control independent providers or guarantee their content or availability simply by linking to them.

16.2. A hosting platform may apply its own access controls or require a separate sign-in. Follow the applicable platform conditions when using that platform. A platform login does not automatically create a unified Minigames account or recover a guest record.

16.3. Providers engaged by us may help host, store or operate the Service. We remain your contracting party for the Service we provide. References to third parties do not excuse our own obligations or responsibility for providers we engage to perform them.

17.1. Contact us with questions, suggestions, error reports or security concerns. We do not promise a particular response time or support service level unless expressly agreed or required by law.

17.2. If you voluntarily suggest an improvement to the Service, you permit us to use and implement that suggestion without payment or attribution. This permission does not transfer ownership of unrelated creative work or personal information included in your message.

17.3. A support explanation does not certify a score, guarantee recovery of progress, provide professional advice or change these Terms unless we expressly agree a binding change with you.

18.1. We may maintain, correct, update, replace, limit, or discontinue the Service or an individual Game for reasons including security, legal compliance, technical compatibility, correction of errors, prevention of misuse, development of the offering, or commercial sustainability.

18.2. We may apply reasonable limits on request frequency, stored volume, account activity, processing time or other resource use. Relevant material limits will be disclosed before you commit to an affected offering. Changes affecting existing access or saved progress remain subject to the notice and remedy protections in these Terms and applicable law.

18.3. We do not promise uninterrupted operation, permanent availability of a particular Game or version, compatibility with every environment, or implementation of a planned feature. Temporary interruptions may occur during maintenance, failures, or circumstances outside our reasonable control.

18.4. Where reasonably practicable, we will give advance notice of a material reduction or discontinuation affecting an ongoing offering. Urgent security, legal, or operational action may require a change or interruption without advance notice.

18.5. Changes remain subject to any existing contractual commitments and mandatory requirements concerning notice, continued conformity, cancellation, refunds, or other remedies. Where the law requires notice on a durable medium or a right to terminate, we will provide it.

18.6. We are not responsible for a delay or failure to perform to the extent it is caused by an event beyond our reasonable control that we could not reasonably prevent or overcome. We will take reasonable steps to limit its effect. This does not remove a statutory right to end an affected contract or obtain a remedy.

19.1. We may suspend or restrict access where reasonably necessary because of a material breach of these Terms, unlawful activity, a security risk, misuse of resources, infringement of rights, or a legal requirement. We may also end an offering in accordance with section 18.

19.2. Measures may include rejecting a result or request, correcting or removing a leaderboard entry, removing unlawful content, limiting requests, disabling a sharing function, suspending an account, or blocking access. We will aim to make a restriction proportionate to the issue and consider its seriousness, repetition, and effect on other people. Urgent or serious threats may require immediate action.

19.3. Where lawful and reasonably practicable, we will explain the reason for a restriction and provide an opportunity to correct a remediable breach. We may withhold information where disclosure would compromise security, another person's rights, or a legal obligation. You may contact us if you believe a restriction was applied in error.

19.4. You may stop using the free Service at any time. Stopping use does not create a fee, but does not remove obligations or liabilities already arising from your previous use.

19.5. When access ends, your permission to access the affected Service ends. The permissions for screenshots and recordings lawfully made under section 14 continue unless the particular material was obtained unlawfully or its continued use infringes another person's rights. Provisions intended to continue, including ownership, liability, accrued claims, and dispute provisions, survive as applicable.

19.6. Where an account feature exists, you may request account closure through its available controls or by contacting contact@buildner.com. We may take reasonable steps to verify that you are entitled to close the account. Retain permitted material you need before closure. Account closure does not transfer ownership of Your Content to us, and the storage and deletion provisions continue to apply.

19.7. Content and abuse restrictions may be applied following a user report, a legal notice, security information, or checks associated with the feature you use. Where automated screening or decision-making is used, we will explain its role and the available review process in the relevant feature information or restriction notice, as required by law. These Terms do not promise that every result, profile or contribution is checked, and do not treat passing a check as approval of its legality or accuracy.

19.8. Where required by law, we will provide a clear statement of the reasons for a content or account restriction, its scope and duration where known, the contractual or legal ground, the role of automation, and the means to challenge it. You may request review at contact@buildner.com. We will consider relevant information and provide human review where applicable law requires it. These arrangements do not limit any other available complaint or redress procedure.

20.1. The Service is supplied for the limited purposes described in these Terms and the relevant Game. Subject to section 21.1 and mandatory law, it is provided on an “as is” and “as available” basis.

20.2. To the extent legally permitted, we give no additional warranty that the Service or a result will be error-free, complete, continuously available, suitable for every particular purpose, compatible with every system, or capable of achieving a particular recreational, competitive, commercial, academic or professional result.

20.3. We do not guarantee that every defect, manipulation, invalid score or interruption will be detected or corrected, or that the Service will preserve every attempt or maintain a particular ranking.

20.4. For Business Users, and to the extent permitted by law, implied warranties, conditions, and terms concerning satisfactory quality, merchantability, fitness for a particular purpose, and non-infringement are excluded.

20.5. For Consumers, nothing in this section excludes statutory requirements concerning conformity, reasonable care and skill, security, remedies, or binding descriptions of the Service. Describing a Game as free, experimental, or a preview does not remove rights that the law gives you.

21.1. Liability that is not excluded. Nothing in these Terms excludes or limits liability for fraud, fraudulent misrepresentation, wilful misconduct, gross negligence, death or personal injury caused by negligence, or any other liability to the extent its exclusion or limitation is prohibited by applicable law. Nothing removes a non-excludable consumer right, statutory remedy, or right to compensation. This section takes priority over every exclusion, limitation, and indemnity in these Terms.

21.2. Matters outside our responsibility. Subject to section 21.1, we are not responsible for loss to the extent it results from inaccurate or unauthorised submissions, use contrary to clear Game instructions, changes made by you or an independent third party, or decisions for which the Service does not undertake responsibility. This does not exclude responsibility for our own breach or an error for which we are legally liable.

21.3. Business losses excluded. For Business Users, and to the fullest extent permitted by law, we are not liable for indirect, consequential, special, exemplary, or punitive loss, or for loss of profits, revenue, business, contracts, anticipated savings, opportunity, goodwill, or reputation. We are also not liable for loss or corruption of data, loss of use, business interruption, or wasted expenditure, whether those listed losses are direct or indirect.

21.4. Business use of game results. Subject to section 21.1, the business exclusions include loss caused by reliance on a Game result as a professional assessment, design approval, employment assessment or guarantee of an external competition outcome. They also include business losses from interruption of an event or teaching session, to the extent permitted by law. These exclusions do not turn an expressly promised paid or promotional benefit into a discretionary one.

21.5. Business liability cap. Subject to section 21.1, our total aggregate liability to a Business User for all claims arising from or relating to the Service and these Terms is limited to the greater of EUR 100 and the fees that Business User paid us for the affected features of this Service during the 12 months immediately before the event giving rise to the first claim. For a series of related events, the first event is used. Fees paid for separate Buildner services are not included. This limit applies collectively across contractual, tort, negligence, statutory, and other claims to the extent the law permits.

21.6. Consumers. The business exclusions and cap in sections 21.3–21.5 do not apply to Consumers. Our responsibility to Consumers is determined by applicable law. Where the law permits a limitation by reference to foreseeability, we are responsible for loss that is a foreseeable result of our breach or failure to exercise the care and skill required by law, and are not responsible for loss that was not reasonably foreseeable. All mandatory rights to repair, correction, price reduction, refund, termination, or compensation remain available where applicable.

21.7. Avoidable loss and contribution. Each party must take reasonable steps to reduce a loss where the law requires it. Liability may be reduced to reflect the other party's contribution to a loss to the extent permitted by law. No clause reverses a statutory burden of proof or makes a Consumer responsible for our breach.

22.1. This section applies only to Business Users. To the extent permitted by law, you will indemnify us against reasonably incurred losses, liabilities, and reasonable legal costs resulting from a third-party claim to the extent caused by your material breach of these Terms, unlawful use of the Service, or Your Content that infringes the third party's rights.

22.2. This obligation does not apply to the extent a claim is caused by our breach, negligence, misconduct, or an alteration or use of Your Content that you did not authorise. It does not make you responsible merely because a third party alleges wrongdoing.

22.3. We will give reasonably prompt notice of the claim, allow reasonable participation in its defence, and take reasonable steps to mitigate loss. You are not required to fund a settlement entered into without your consent, which must not be unreasonably withheld. No settlement may impose an admission, non-monetary obligation, or restriction on either party without that party's agreement.

22.4. Consumers are not subject to this contractual indemnity. Any responsibility they have for unlawful conduct or loss they cause is determined by applicable law.

23.1. Contact us using section 27 if you have a complaint, encounter a material error, believe your access was wrongly restricted, discover a security issue, or consider that material stored or made available through the Service is illegal or infringes your rights. You may also use a reporting control offered for the relevant feature.

23.2. To help us investigate, identify the relevant page, Game, profile, result, or content location; describe the issue and why you consider it unlawful or otherwise objectionable; and provide a way to contact you. For a rights complaint, identify the protected material and explain your authority to act. For a technical error, include the approximate time and game version and any result or report reference. Submit reports in good faith, state that the information is accurate to the best of your knowledge, and share only what is necessary. Any legal exception to a requirement to identify yourself remains available.

23.3. If you discover a vulnerability, stop any activity that risks harm or unauthorised access and report it privately. Do not access another user's materials, extract data, or disrupt the Service to demonstrate the issue. A report does not itself authorise further security testing.

23.4. We will consider complaints and notices in good faith and respond as required by applicable law. We may request reasonably necessary information and take proportionate action, including correcting a Game or restricting disputed material.

23.5. Contacting us is encouraged but is not a mandatory condition before exercising a legal right, making a regulatory complaint, seeking urgent relief, or starting proceedings. These Terms do not shorten a statutory limitation period.

23.6. Where applicable law requires it, we will acknowledge a content notice, communicate the resulting decision and available review options, and provide the legally required information about automated processing of that notice. Do not knowingly submit false reports or use the complaints process to harass another user.

24.1. We may update these Terms to reflect changes to the Service, business arrangements, applicable law, security requirements, or identified drafting errors. We will publish the revised wording with an updated date.

24.2. For a material change affecting an ongoing relationship, we will give reasonable advance notice through the Service or another appropriate channel, and obtain fresh acceptance where required by law. An urgent legal or security change may take effect sooner where permitted and necessary; we will explain it as soon as reasonably practicable.

24.3. Changes apply prospectively. They do not retrospectively impose a fee, transfer ownership of Your Content, remove an accrued claim, or rewrite a completed purchase.

24.4. If you do not agree to a revised version, stop using the affected Service before it takes effect. Continued use constitutes acceptance only where you have received legally sufficient notice and applicable law permits that method of acceptance. Rights concerning cancellation, refunds, or termination of an existing paid arrangement remain unaffected.

24.5. Introducing paid access remains subject to section 4. Posting revised Terms alone does not authorise us to charge you.

25.1. These Terms and disputes relating to the Service are governed by the laws of the Principality of Andorra, subject to mandatory rules that apply regardless of a choice of law.

25.2. If you are a Consumer, this choice does not deprive you of mandatory protections available under the law that would otherwise apply, including protections of your country of habitual residence where applicable.

25.3. For Business Users, the competent courts of Andorra have exclusive jurisdiction over disputes relating to these Terms or the Service, except where a mandatory rule requires otherwise.

25.4. Consumers may bring proceedings in any court available to them under mandatory law, including the courts of their place of residence where applicable. We will bring proceedings against a Consumer only in a court permitted by applicable law.

25.5. These Terms do not impose mandatory arbitration, waive a right to participate in proceedings where that right is protected by law, or restrict your right to complain to a competent public authority.

26.1. Entire agreement for this Service. These Terms, properly notified Game-specific terms, and any express written agreement for this Service form the agreement concerning this Service. They do not replace contracts for other services or exclude a statement or representation that applicable law makes binding.

26.2. Severability. If a provision is invalid or unenforceable, it will not apply to the extent of that invalidity, and the remainder continues where legally possible. An unfair consumer term will not be rewritten merely to make an otherwise unlawful restriction enforceable.

26.3. No waiver. A failure or delay in enforcing a provision does not waive the right to enforce it later. A waiver of a particular breach does not waive a later breach.

26.4. Transfer. You may not transfer a licence to access the Service without our permission, except where the law permits it. We may transfer our rights and obligations as part of a lawful reorganisation or transfer of the Service, provided this does not reduce your mandatory rights or the guarantees owed to you. We will give notice where required.

26.5. No partnership or agency. These Terms do not create a partnership, employment, agency, or joint venture. Neither party may commit the other to obligations without authority.

26.6. Communications. We may provide Service notices electronically where the law permits. This does not amount to consent to marketing. Formal notices must use a method and address permitted by applicable law.

26.7. Language. These Terms are issued in English. If a translation is provided, applicable consumer-language requirements and legal rules on interpretation continue to apply; this clause does not override them.

A. Brief Encounter

A.1. Brief Encounter is a tile-based floor-plan puzzle. Success means arranging the supplied rooms within the playable footprint and meeting the particular fictional client requirements. Optional elegance checks, stars and points assess only the relationships recognised by that challenge.

A.2. Room adjacency, orientation and fit are simplified game rules. A valid solution does not confirm usable room dimensions, circulation, daylight, ventilation, structure, services, fire safety, accessibility, building regulations or planning compliance. A client remark is fictional feedback, not a professional review.

A.3. The available briefs and the Game’s displayed scoring rules define the challenge. Reusing a successful layout, experimenting, undoing and restarting through the normal controls are permitted. Completing a puzzle does not automatically create a public ranking or permanent player record where the Game does not offer those features.

B. Load-Bearing Ego

B.1. Load-Bearing Ego is a stylised stacking and balance Game. Stable placements and the longest stable overhang determine the current score. A collapse can end the run and submit the last eligible stable result; an explicit finish action can bank an eligible standing result. An unstable final floor does not turn a previous stable placement into real-world structural evidence.

B.2. The model simplifies mass, support overlap and centre of mass. It does not calculate real material strength, connections, load combinations, foundations, deflection, wind, seismic response, fatigue or construction methods. Dimensions and structural labels are illustrative game quantities and must not be used to design or approve a building.

B.3. The current ranking board records eligible anonymous runs, rather than verified people. Multiple legitimate runs may appear. A result is saved only after server acceptance. Recalculation of placement history checks the supported game rules; it does not establish human play or certify the structure. Raw points are not directly comparable with those of the other Games.

C. Something’s Off

C.1. Something’s Off is an observation Game in which you identify a selected visual inconsistency in a stylised façade. A round has the target defined by its generator and rules. Other differences you notice are not necessarily scoring targets.

C.2. The current scoring system combines precision, pace and consistency across a run. Mistakes, active answer time and consecutive accurate answers affect the score according to the Game’s displayed rules. Browser and input differences can affect timed performance.

C.3. Where available, guest rankings compare compatible scoring and generator versions and use the guest’s best eligible finished run within the selected period. Guest labels are not verified identities. Clearing the identity cookie may create a new guest without removing earlier records. Validation does not independently verify every answer or timing claim.

C.4. The Game is not a visual-acuity test, diagnostic assessment, façade inspection, defect-detection service or measure of professional attention or competence.

D. Site Visit

D.1. Site Visit is a corridor-tile puzzle. Rotating tiles creates the route required by each supplied floor. Completion, rotation efficiency and use of hints affect results as described in the Game. A displayed par is a game benchmark, not an architectural standard.

D.2. The current Game can store progress and best eligible floor results on the server using a browser-linked guest identity. A shared ranking may combine that guest’s best results across the supported floors and display a generated visitor label. Clearing the guest cookie can prevent restoration of that history even if records remain stored.

D.3. A connected route does not verify real circulation, travel distance, door operation, capacity, accessible access, fire compartmentation, emergency evacuation, lift safety or any building approval. The moving character and destination are game elements, not a simulation of occupant behaviour.

E. Permit Pending

E.1. Permit Pending is a fictional proposal-review Game. Decide whether to approve or reject proposals against the rules and amendments currently shown on the planning desk. A correct decision means consistency with those displayed game rules.

E.2. The town, planning conditions, proposals, approval stamps and remarks do not represent the law or policy of a real authority. Approval does not grant a permit; rejection does not determine the legality or merits of a real project. The Game is not training or certification for regulated decision-making.

E.3. The current standard shift scores completed decisions for accuracy and a consistency bonus. It does not award a speed bonus. Results apply to the current run; the present Game does not promise durable personal bests, a shared leaderboard or a registered player profile. A browser-calculated practice result is not a verified competitive entry.

F. Versions and future Games

F.1. These descriptions address the collection available when this version was prepared. The relevant Game explains the rules for the version you actually play. A material new feature, paid offering or promotion must have any further information or terms required by law before you commit to it.

F.2. We may add, update or retire Games subject to sections 18 and 24. The inclusion of possible future functionality in these Terms is not a launch commitment or permission to change an existing paid promise without the required notice and remedies.
