How to play Ten seconds

This is a test of your inner clock. Tap Start to begin timing, then tap Stop the instant you think exactly ten seconds have passed. The catch: the timer is hidden the whole time, so you have to feel it. When you stop, the game reveals your time and how many milliseconds you were off. Your closest ever attempt is saved as your best.

Tips

• Do not count out loud too fast, most people rush it
• Find a steady rhythm and trust it
• Try counting one thousand one, one thousand two, and so on
• A few practice runs will calibrate your sense of time
