Frequently asked questions

Are these games and tests free?

Yes — every game and test here is completely free, with no account and no limits. Just open one and start.

Do they work on mobile?

The click speed and reaction tests work great on touchscreens. The keyboard tester needs a physical keyboard, so it's best on a laptop or desktop.

Are my scores saved?

Your best scores are stored privately on your own device (in your browser), never uploaded — so they're there when you come back to beat them.
