Privacy Policy

Last updated: October 9, 2026

This Privacy Policy explains how https://blockblast.co ("the Website", "we", "us") handles information when you visit it, play its games, read its guides or use its Block Blast solver. The Website is operated by Pattern Hub, LLC.

The Website has no user accounts, registration, purchases or newsletter. Some games and tools let you type names or options, for example Spin the Wheel, Ladder Game and Marble Race Picker. What you type stays in your browser as described in section 2. It is not sent to us, and it is masked in Microsoft Clarity recordings.

1. Cookies and Similar Technologies

  • NEXT_LOCALE: set by the Website to remember the language version you are using, so you see the same language on your next visit. It expires after one year.
  • Analytics and advertising: Google Analytics, Microsoft Clarity and Google's advertising services may set their own cookies or use similar technologies, as described in sections 3 and 4.
  • Consent choices: Google's consent management platform stores the choices you make in its consent message (see section 5) in a cookie, so that the message does not appear on every page.

2. Information Stored in Your Browser

Some features save small settings in your browser's local storage. This information stays on your device, is not sent to us, and remains until you clear your browser's site data.

  • Language suggestion bar: lastLanguagePrompt and dontShowLanguagePrompt remember when the bar was shown and whether you closed it.

An earlier key, blockBlast.best, is no longer read but may still sit on your device until you clear site data.

3. Analytics

The Website uses Google Tag Manager, which loads:

  • Google Analytics 4, which collects information about how the Website is used, such as the pages you visit and the type of device and browser you use.
  • Microsoft Clarity, which records how visitors use pages, such as clicks, scrolling and mouse movement, to produce heatmaps and session replays that show how a visit went. Text you type into the Website's games and tools is masked in these recordings.

We also send Google Analytics 4 events about game play itself: which game you started, how long the round lasted and how it ended, such as your score or whether you won. These events contain no personal information.

We measure which recommended game cards you see and click, their position and the page they appear on. The browser's session storage key blockblast:recommendation-click temporarily remembers the most recent same-tab recommendation click so that a game started within 30 minutes can be attributed to it. It is removed when the next game starts, or when the tab's session ends. We also measure Block Blast revive choices and outcomes, including whether play resumes, subsequent moves, score gained and the elapsed time observed on that page.

These services are provided by Google and Microsoft and process information under their own privacy policies:

We use this information to understand which pages and games are used and to improve the Website.

4. Advertising

The Website uses Google AdSense, an advertising service provided by Google, and may show ads to help pay for running the Website.

  • Third-party vendors, including Google, use cookies to serve ads based on a user's prior visits to this Website or other websites.
  • Google's use of advertising cookies enables it and its partners to serve ads to users based on their visit to this Website and/or other sites on the Internet.
  • You may opt out of personalized advertising by visiting Google's Ads Settings (also available at www.google.com/settings/ads). You can also opt out of some third-party vendors' use of cookies for personalized advertising by visiting www.aboutads.info.
  • If you opt out, you may still see ads, but they will no longer be personalized based on your visits to other websites.
  • Other ad technology providers working with Google may also serve or measure ads on the Website. Visitors in the European Economic Area, the United Kingdom and Switzerland can see the list of these providers, with links to their privacy policies, in the consent message described in section 5.
  • How Google uses information from websites that use its services: policies.google.com/technologies/partner-sites.

Visitors from the European Economic Area, the United Kingdom and Switzerland see a consent message from Google's consent management platform, which is certified by Google. In it you choose how your data may be used for advertising, and you can see the ad technology providers that work with Google. You can change your choice at any time with the Privacy and cookie settings link that Google shows at the bottom of the page.

6. Hosting

The Website is hosted by Vercel. Images and other game files are delivered from cdn2.blockblast.co through Cloudflare. As part of delivering the Website, these providers may record technical request information in access logs, such as IP address, requested page or file, time of the request and browser user agent.

7. Games on the Website

All games on the Website run on the Website's own code and load their files from the Website and its file server. The Website does not embed games from other providers. Most games generate their sounds in your browser; the others play sound files from the Website's own file server.

8. Embedded Videos

  • YouTube: before you play a video, the page only loads the video's thumbnail image from i.ytimg.com. The YouTube player (youtube.com) is loaded only after you click the video. From then on, Google may collect information under its privacy policy.
  • TikTok: the page shows a preview card and makes no request to TikTok until you click it. After you click, the TikTok embed script and player are loaded from tiktok.com, and TikTok may collect information under its privacy policy (tiktok.com/legal/privacy-policy).

9. Block Blast Solver

When you use the solver, your screenshot is read and analyzed in your browser. The image is not uploaded to our server. Analytics services described in section 3 may still record your use of the page.

10. Sharing Game Results and Lists

Apple Game, Lemon Game, Animal Connect, Chrome Dino, Minesweeper, Pikachu Volleyball, Ramen Shop, Ladder Game, Marble Race Picker, Level Liar, Reaction Time Test, CPS Test, Aim Trainer, Number Guessing Game, Snake Game and Spin the Wheel have a share button. Only when you click it, the Website opens your device's share menu or, if that is not available, copies your result and a link to your clipboard. What happens next depends on the app you choose to share with.

Marble Race Picker also has a Copy list link button. It puts the names in your list into the part of the link after the "#" sign. Browsers do not send that part of a link to our servers, so the names do not appear in our server logs, but anyone who receives the link can read them. When the link is opened, the names are loaded into the list and removed from the address bar.

11. Your Choices

  • Personalized ads: opt out through Google's Ads Settings or www.aboutads.info, as described in section 4.
  • Consent message: in the European Economic Area, the United Kingdom and Switzerland, use the Privacy and cookie settings link that Google shows at the bottom of the page to change your choice (see section 5).
  • Your browser: you can delete cookies and local storage for the Website at any time in your browser settings, and limit analytics and ads with your browser's privacy settings or content-blocking extensions.
  • Videos are only loaded after you click them.

12. Children

The Website is intended for a general audience and is not directed to children under 13. We do not knowingly collect personal information from children. If you believe that a child has provided us with personal information, please contact us at contact@blockblast.co.

13. Changes to This Privacy Policy

We may update this Privacy Policy when the Website or the services it uses change. The updated policy will be posted on this page with a new "Last updated" date.
