About BenchMyBrain
Free browser games and tests by MeyDev. Play without an account.
What Is This?
BenchMyBrain offers browser games and tests for reaction time, memory, attention, shape matching and typing. 40 activities feed the Brain Score index; other activities and the color vision screening are separate from that score.
Games are built for this site and run in your browser. Your personal bests are saved on this device. Analytics and optional leaderboard submissions are described below.
Scoring Method & Limitations
Brain Score is a site-designed game index. Each of its 40 activities maps your saved personal best to 0–100 using a conversion chosen for this site. The converted results are rounded and averaged over completed activities; the rounded average is multiplied by 10 for Brain Score. The report shows 0–100 averages overall and by activity group.
These scales are not calibrated population norms, IQ scores or clinical assessments. Unplayed activities are excluded, so completing a different mix changes the index. Higher game scores do not establish cognitive improvement. Results from other tests or research protocols are not directly comparable.
Timing is measured in your browser. Timer precision is not the same as measurement accuracy: display refresh, input-device delay, browser scheduling and timer settings can affect the result. Compare your own attempts on the same setup and activity.
No Accounts Required
You don't need to create an account or log in. Your personal bests are saved locally in your browser (localStorage) so you can track progress over time.
Playing does not require an email address or password. Browser storage and analytics still operate without an account.
Privacy & Data
Analytics: We use Google Analytics (GA4) to send usage information to Google, including page views, interactions and browser error events. It helps us understand which activities are used and how visitors find the site.
Analytics cookies: GA4 uses first-party cookies, including _ga and site-specific _ga_* cookies, to distinguish browsers and sessions. This measurement is separate from your locally saved scores. Google's explanation of GA4 cookies.
Payments:Everything is free. If you choose to support the site with an optional donation, it's processed by Stripe — we never see your card details, and it's never required to use anything.
Your test data: Personal bests and family scores are stored in your browser. Clearing browser storage can remove them. Submitting to a public leaderboard sends that score to our server; sharing a challenge link includes your chosen name and score in the link.
Leaderboards: Optional submissions store a browser-generated player identifier, nickname, score and country code. Nickname, country flag and score appear publicly. The leaderboard uses an IP-derived hash to limit requests; the raw IP address is not stored in the leaderboard.
