PRACTICE MODE · TIME PERCEPTION
Time perception test
Ten seconds sounds easy until the clock disappears. This timing challenge asks you to stop an unseen timer as close as you can to the target shown for the round. There is no moving hand to follow and no countdown to rescue you. Start, wait, and commit. Your result shows the actual elapsed time and whether you stopped early or late. Try three practice rounds, then see whether your confidence survives a daily challenge with other skills mixed in.
How scoring works
Start with 100 points and subtract 1 point for each 20 milliseconds of error, whether early or late. Round to a whole number, with a minimum of zero. A 0.2-second miss earns 90 points. The result also shows actual time; this is not a scientific attention or reaction-speed assessment.
A little head start
Choose one strategy for a run: count steadily or trust your sense of duration. Switching halfway through can make your timing harder to compare.
Stay on the game tab and avoid interruptions. A notification or backgrounded browser can change your experience of the round.
Good questions
Is every target exactly ten seconds?
Targets range from five to ten seconds. Check the duration shown before each round. Varying the target keeps you from relying on a single memorized rhythm.
Can I count in my head?
Yes. Pick the approach you enjoy. For a fair comparison with a friend, agree whether you are counting or using pure intuition.
Is this a reaction time test?
No. A reaction test asks you to respond to a signal. Here you estimate an interval and choose when to act without an external stop signal.
