It is a beat-the-clock speed game built from CAPTCHA-style challenges · reading distorted codes, selecting the right tiles, spotting a tilted tile, and tapping numbers in order. You solve a short run of them as fast as you can and try to beat your personal best.

What happens if I get one wrong?

Nothing ends · you simply retry the same challenge, and the stopwatch keeps running. A mistake costs you time rather than the whole run, so the best scores come from being both fast and accurate.

How is my best time saved?

Your fastest run is stored per difficulty in your browser, so Easy, Medium and Hard each keep their own record. If you sign in, your records sync to your account and follow you across devices.

Is this a real CAPTCHA?

No · it does not verify anything or talk to any server. It just borrows the familiar shapes of CAPTCHA challenges and turns them into a timed game. It runs entirely in your browser.

Does it work offline?

Yes. PlayMemorize is a Progressive Web App, so Human Timer keeps working without a connection once the page has loaded.
