Quick browser challenges you can play in seconds — measure your click speed (CPS), test your reaction time, and check every key on your keyboard, plus classic randomizers like spin the wheel, dice, and coin flip. Everything runs in your browser, with no sign-up and nothing to install.

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