Terms of Service

Last updated: 13 November 2026. These Terms of Service ("Terms") are the agreement between you and the operator of Trending Brain Games. Please read them together with our Privacy & Cookies Policy.

1. Who provides the game, and accepting these Terms

Trending Brain Games (trendingbraingames.com) is created, published and operated by Zentra Gadgets (zentragadgets.com). In these Terms, "we", "us" and "the operator" mean Zentra Gadgets, and "the game" or "the site" means Trending Brain Games. By opening, accessing or playing the game, you accept these Terms and the Privacy & Cookies Policy. If you do not agree with any part of them, please do not use the site. Where a child plays, a parent or guardian should read these Terms with them and is responsible for the child's use of the site.

2. What the game is

Trending Brain Games is a free brain-training game that runs in your web browser — no download, no account and nothing to install. It contains 150 categories with 500 levels each (75,000 levels in total), and every level contains exactly 10 questions or tasks. It offers three age groups (Kids 5–12, Teens 13–17 and Adults 18+) and three modes (Easy, Hard and Expert), an explanation after every answer, learning facts at the end of every level, stars, XP, a Brain Level and Brain Score, and 14 achievements in the Trophy Case. Once the game has loaded, it can also be played offline on devices and browsers that support that.

3. The game is free

The whole game is free to play. Every category and every level is opened by playing and progressing — there are no in-game purchases, no paid unlocks and no subscriptions. The only money that can ever change hands is a voluntary support contribution under section 8, and giving one is never required to play.

4. Your progress, scores and device storage

Your progress, scores, achievements and settings are stored only on your own device, in your browser's local storage, exactly as described in the Privacy & Cookies Policy. Because we never receive a copy of that data: we cannot see it, transfer it to another device, or restore it if it is lost. Clearing your browser's cookies or site data permanently deletes it. Playing on a different device or browser starts a fresh game. Stars, XP, Brain Level, Brain Score and achievements are part of the game experience only — they have no cash value, are not money or property, and cannot be exchanged, transferred, redeemed or cashed out.

5. Fair play and acceptable use

You are welcome to play the game as often as you like, for personal, non-commercial use, and to share the link to the site with anyone. You agree that you will not:

• Try to disrupt, damage, overload or interfere with the site, or attempt to gain unauthorised access to any system behind it.
• Copy, scrape, extract or republish the game's question banks, questions, explanations, learning facts, design or code — in whole or in large part — especially for commercial use, without our written permission.
• Present the game, or content taken from it, as your own work or as the product of anyone other than Zentra Gadgets.
• Use the site for any unlawful purpose, or in any way that infringes the rights of others.

6. Intellectual property

The game — including its name and branding, design, graphics, code, categories, questions, answer options, explanations and learning facts — belongs to Zentra Gadgets or is used with permission. These Terms give you a personal, non-transferable licence to play the game in your browser. They do not transfer any ownership to you, and no part of the game may be reused commercially without written permission from Zentra Gadgets.

7. Accuracy of content

We work hard to keep every question, answer and explanation correct, and levels are reviewed and improved over time. Even so, an occasional mistake can slip through. If you spot one, email info@zentragadgets.com and it will be put right. The game — including its professional-style categories such as Accounting & Finance Pro and Clinical Care Pro — is for learning and entertainment. Its content is general knowledge practice, not professional advice of any kind (medical, financial, legal or otherwise), and it must not be relied on as a substitute for a qualified professional.

8. Support contributions and refunds

The "Support us" option exists so players who enjoy the game can voluntarily support its developer. No bank details are shown in the game. The terms for those contributions are:

• Voluntary: a contribution is a gift of support that you choose to make. It is never required, and the full game is free whether or not you contribute.
• Not a purchase: a contribution is not payment for goods or services. Nothing is sold in return — no levels, features, advantages or items are unlocked by contributing, because everything in the game is already free.
• Generally non-refundable: because a contribution is a voluntary gift of support rather than a purchase, it cannot normally be refunded once it has been sent.
• Mistaken payments: if you sent a contribution by genuine mistake — for example the wrong amount, or the same transfer sent twice — email info@zentragadgets.com within 14 days of the transfer, giving the date, the amount and the reference you were given. If we can verify the mistake, we will return that transfer in full.
• Refunds go back to the source: any refund is paid only to the same account the contribution came from — never to a different account, a different person, or in cash. Once a refund is verified, we will arrange it promptly; how long it then takes to reach your account depends on the providers involved.
• No bank details in the game: the game does not display any bank details for support. We cannot be responsible for payments sent to details obtained from anywhere else.

9. Availability and changes to the game

We may update the game at any time — correcting questions, improving levels, adding or removing categories or features, and fixing problems. The site may occasionally be unavailable, for example during maintenance or because of hosting or network issues outside our control. We aim to keep the game available and improving, but we do not guarantee uninterrupted access.

10. No warranties

The game is provided "as is" and "as available". To the fullest extent permitted by law, we do not promise that the game will be completely error-free, that every question is free of mistakes, or that progress saved on a device can never be lost — device storage is under your browser's control, not ours (see section 4).

11. Limitation of liability

To the fullest extent permitted by law, the operator is not liable for: loss of progress, scores, achievements or settings stored on a device; indirect or incidental losses arising from using or being unable to use the site; or the content of external websites the site links to. Nothing in these Terms excludes or limits any liability that cannot legally be excluded or limited.

12. Links to other websites

The site links out to zentragadgets.com and to email. We do not control those websites or services, and their own terms and privacy policies apply when you use them.

13. Changes to these Terms

If these Terms change, the updated version will be published here with a new "last updated" date, and the changes will apply from that date. By continuing to play after a change, you accept the updated Terms. If you do not agree with a change, please stop using the site — you can remove everything the game saved at any time by clearing your browser's site data.

14. General

If any single part of these Terms is found to be unenforceable, the remaining parts continue in full effect. These Terms, together with the Privacy & Cookies Policy, are the whole agreement between you and the operator about Trending Brain Games.
