Taikan — 10 second challenge — stop at exactly 10.00

A 10 second challenge in your browser. Tap (or press Space) to start the clock and again to stop it. The number is only visible for about the first 3 seconds — after that you count on your own and aim for exactly 10.00. When you stop, your time (to two decimals) and how far off you were (e.g. +0.37s) are shown big, with a one-word verdict from “Spot on” to “Try again”. Choose 5, 10 or 30 seconds; your smallest gap is saved on your device as your personal best.

How to play

  1. Pick a target at the top: 5, 10 or 30 seconds (10 by default)
  2. Tap the screen or press Space to start. The number hides after about 3 seconds
  3. When you think exactly that many seconds have passed, tap again to stop
  4. You get your time and the gap to the target (+ is late, − is early). Your smallest gap is saved as your best. No rankings or averages

Keyboard: Space or Enter start / stop / again / ←→ change the target (5, 10, 30 s)
