10 Second Challenge

How to play

1. Enter players and choose a target time.
2. Start the challenge. After 3, 2, 1, count in your head and press STOP.
3. Take turns and see who gets closest to the target.

Elapsed time stays hidden until you stop. The smallest absolute difference wins; equal hundredth-second differences tie. Leaving the tab cancels the current turn so you can retry.

Try it with your group

With three players, give everyone one attempt at ten seconds on the same device. Closest wins even if the time is over the target. If the displayed hundredth-second errors tie, share the rank or agree on a new round; this is not precision timing equipment.
