Dead On

You see the clock for one second. Then you're on your own.

How to play

Everyone gets the same target each day, somewhere between 3 and 10 seconds, to the millisecond.
Press Start, count in your head, and press Stop when you think the target has passed. The clock hides after the first second.
You get 3 attempts a day and your best one counts. Within 0.010s of the target is dead on.
Your attempts are saved on this device only. A new target arrives at midnight.
