On Time - Timer Game

How well do you know 10 seconds?

On Time is a minimalist timing game that tests your internal clock. Press START, count to ten in your head, and press STOP. That's it. Simple to learn, impossible to master.

Your goal: stop the timer as close to 10.00 seconds as possible — without looking at the numbers ticking up.
