A five-round timing game

Can you stop at exactly one second?

Start the timer, then stop it when you think exactly 1,000 milliseconds have passed. The number stays hidden until your second press.

All five results stay on this page and disappear when you reload it.

You can use Enter or the space bar.

What enters the score

The device is part of the result.

We calculate the interval between two activations of the same button. The result includes your timing, screen, keyboard or touch latency, and whatever work the browser is doing at that moment.

Average miss uses each attempt's distance from the target. Average direction keeps the sign and shows whether the series leaned early or late. The game describes these five presses on this device.
