About this tool
The 10-Second Challenge is a quick time-sense game for anyone who thinks they have a good internal clock.
Press Start and the timer runs for a few seconds, then the numbers disappear and you are on your own. Tap Stop at the exact moment you feel the target time has passed.
You can choose a 5, 10 or 30 second target, and the closer you get, the better your rank: God hand, Human clock, Good instincts, So close, or Try again.
The game uses the high-resolution clock in your browser, so the result is shown instantly with the difference to a hundredth of a second.
Your best record for each target stays on your own device, and you can post your closest record to the weekly TOP 10 under a nickname if you want to compete with others.
It is made purely for fun and as a small break, so share your result and challenge a friend to beat it.
