Terms of Use — Block King: Blast & Cube Crush

Effective date: 27 October 2026 Last updated: 27 October 2026

These Terms of Use ("Terms") are a legal agreement between you and Questar Games ("we", "us", "our") governing your use of the mobile game Block King: Blast & Cube Crush (the "Game"). By downloading, installing, or using the Game you agree to these Terms. If you do not agree, do not use the Game.

Browser previews and YouTube Playables

These Terms also cover browser and YouTube Playables versions of Block King. You may play them for personal, non-commercial entertainment. Authorized platform reviewers may perform technical testing and certification. This section takes precedence over mobile-only descriptions below, including app-store billing, purchase restoration and native advertising. Your mandatory consumer rights remain unaffected.

The current standalone website preview has no in-game advertising or purchases. It stores progress and settings in your browser; clearing site data or loss of browser storage may erase them. Saves, purchases and entitlements do not transfer between the website preview, the native apps and YouTube.

When available on YouTube Playables, the game is also subject to the YouTube Terms of Service. Any supported advertising uses YouTube’s functions; these Playables do not offer off-platform purchases. Optional rewards require the host to confirm completion of the relevant ad. An unavailable ad does not entitle a player to a reward.

A compatible browser or host and a network connection may be needed to load the game or use platform storage. Features and availability can differ by version. Preview access does not guarantee publication on YouTube or continued preview availability. Our website Terms of Use cover use of the surrounding website, and our website Privacy Policy explains website processing. Other provisions below apply where relevant.

Intellectual property and reverse engineering

The Block King game builds, including browser and YouTube Playables versions, include protected code, artwork, audio and other materials. Their intellectual property rights belong to Questar Games or the relevant third-party rightsholders. Access grants only the permissions stated in these Terms or the applicable licence.

Except as authorized below, you must not decompile, disassemble or reverse engineer the software; extract or reconstruct its protected source code or assets; or make, distribute or publish unauthorized copies or derivative games that reproduce protected code or assets. This includes using AI-assisted decompilers or reconstruction tools, or supplying game code or assets to such tools for those prohibited purposes.

These restrictions do not prevent ordinary play and the loading or browser caching it requires. They do not prevent access, testing, analysis or certification by YouTube, other host platforms or reviewers within the scope of our written authorization or applicable platform agreements.

Nothing in these Terms limits rights granted by third-party or open-source licences, or exceptions under applicable law, including lawful backup, observation, study, testing, interoperability and fair use where their legal conditions are met. We do not claim copyright ownership of ideas, general game mechanics or independently created material. These exceptions also apply to overlapping restrictions elsewhere in these Terms. Other uses of protected materials require permission from the relevant rightsholder.


1. Licence

We grant you a personal, limited, non-exclusive, non-transferable, revocable licence to download and use the Game on a device you own or control, for your own personal, non-commercial entertainment, subject to these Terms and the applicable app store's terms.


2. Eligibility

The Game is intended for a general audience and is not directed to children under 13 (or the minimum age required in your country). By using the Game you represent that you meet the minimum age and have the capacity to accept these Terms.


3. In-app purchases

  • The Game offers a one-time, non-consumable "Remove Ads" purchase on supported platforms. Prices are shown in the Game and charged by the Apple App Store or Google Play.

  • All purchases are processed by the app store, not by us. Payment, billing, and refunds are subject to the app store's terms and policies.

  • Restore Purchases: if you reinstall or switch devices using the same store account, you can restore a previous "Remove Ads" purchase from the Game's settings at no additional charge.

  • Except where required by law or the app store's policies, purchases are non-refundable.


4. Advertising

Unless you have purchased "Remove Ads", the Game displays advertising provided by third-party ad networks through Unity LevelPlay mediation. Ads may be personalized or non-personalized depending on your consent and device settings, as described in our Privacy Policy. We are not responsible for the content of third-party advertisements.


5. Virtual items

The Game may include virtual items such as gems, scores, and progress. These have no monetary value, cannot be exchanged for real money or goods, and are licensed to you — not sold. We may modify, manage, or remove virtual items at any time. Locally stored progress may be lost if you clear data or uninstall the Game.


6. Acceptable use

You agree not to:

  • Reverse engineer, decompile, disassemble, or attempt to derive the source code of the Game, except to the extent this restriction is prohibited by law;

  • Cheat, exploit bugs, use unauthorized third-party software, or otherwise interfere with the intended operation of the Game;

  • Use the Game for any unlawful purpose or in violation of these Terms or the app store's terms;

  • Copy, distribute, or create derivative works of the Game or its assets.


7. Intellectual property

The Game and all associated content, artwork, code, trademarks, and other materials are owned by Questar Games or its licensors and are protected by intellectual property laws. Except for the licence in Section 1, no rights are granted to you. Third-party components are used under their respective licences, which are available in the Game's "Open-source licenses" screen.


8. Availability and updates

We may update, modify, suspend, or discontinue the Game (or any feature) at any time without notice. We are not liable to you for any modification, suspension, or discontinuation of the Game.


9. Disclaimers

The Game is provided "as is" and "as available", without warranties of any kind, whether express or implied, including but not limited to warranties of merchantability, fitness for a particular purpose, and non-infringement. We do not warrant that the Game will be uninterrupted, error-free, or free of harmful components.


10. Limitation of liability

To the maximum extent permitted by law, Questar Games and its suppliers will not be liable for any indirect, incidental, special, consequential, or punitive damages, or any loss of data, progress, profits, or goodwill, arising from or related to your use of (or inability to use) the Game. To the extent liability cannot be excluded, our total aggregate liability is limited to the amount you paid us (if any) for the Game in the twelve months before the event giving rise to the liability.

Nothing in these Terms limits liability that cannot be limited under applicable law, including your statutory consumer rights.


11. Termination

These Terms apply until terminated. Your licence ends automatically if you breach these Terms. You may end it by uninstalling the Game. Sections that by their nature should survive termination (including Sections 5–10 and 12) will survive.


12. Governing law

These Terms are governed by the laws of the jurisdiction in which Questar Games is established, without regard to its conflict-of-laws rules, and subject to any mandatory consumer-protection laws of your country of residence.


13. Changes to these Terms

We may revise these Terms from time to time. The "Last updated" date above will reflect the latest version. Continued use of the Game after changes take effect constitutes acceptance of the revised Terms.
