The 10 Second Challenge trains your internal clock. Start the timer, wait, then stop as close as possible to 10.000s. Optional hidden-clock mode makes it harder.
How to play
- 1Optionally hide the running clock.
- 2Start the timer.
- 3Stop when you think exactly 10 seconds have passed.
- 4Review your stop time and absolute error.
Tips
- • Count steadily instead of rushing the final second.
- • Try visible mode first, then hidden mode.
- • Compare absolute error across attempts, not just one lucky stop.
