About this game

Time estimation tests how accurately you can measure a short stretch of time without a clock. You click Start, the stopwatch runs hidden, and you stop it when it feels like ten seconds have passed. Nothing changes on the screen in the meantime, so all you have is your own sense of time or counting in your head.

You get three attempts. The result is the average deviation from the target: if you stop at 10.37 s, 9.81 s and 10.08 s, the deviations are 0.37, 0.19 and 0.08 seconds and the result is 0.21 s. It does not matter whether you stop early or late, only the distance from ten seconds counts. An attempt shorter than 2 seconds or longer than 30 seconds does not count and is played again.

It is a short game about your sense of time, not a psychological or medical test. The comparison with other players is a rough guide.

How to read your result

The main number is the average deviation of your three attempts from ten seconds, shown in seconds to two decimal places, so lower is better. Zero would mean stopping all three attempts exactly on target.

Below the main number you will find a scale from 8 to 12 seconds with the target and the marks of your three attempts, and under it the time and deviation of each attempt. If all three end after the target, or all before it, we also show a lean: whether you tend to stop too late or too early. From three attempts this is only a hint, not a trait. A difference of a few hundredths of a second between two games means nothing. The bands in the table are provisional for now, treat them as a rough split, not as a norm.

s
Excellent ≤ 0.20 s An average deviation of two tenths of a second at most. Your sense of time was spot on.
Precise ≤ 0.50 s On average, your attempts are within half a second of the target.
Average ≤ 1.00 s The middle band. On average, your estimate was off by half a second to a full second.
Less precise > 1.00 s A less precise estimate. On average, your attempts miss the target by more than a second.

What affects the result

The time is measured from pressing Start to pressing Stop. What counts is the moment you press the button or the space bar, not when you release it, so the device plays a smaller part here than in reaction time. What matters more is whether you count in your head, how fast you count and whether something distracts you during an attempt.

You can try counting in your head at a steady rhythm, or just feeling the time instead, and compare which way works more accurately for you. Your sense of time is not fixed: in a hurry, under stress or when tired it can run differently than when you are calm. So compare mostly your own games.

Frequently asked questions

What is a good result?

There is no published norm for this game. The bands next to the result are a provisional rough split, and the percentile shows a rough comparison with other players on this site once there are enough of them.

Why is the elapsed time hidden?

That is the point of the game. The stopwatch runs hidden and nothing on the screen changes during an attempt, so you can only rely on your own sense of time or on counting in your head.

Can I count in my head?

Yes, it is up to you. Counting in your head helps some people, others estimate time more accurately by feel. Try both and compare your results.

Why did one of my attempts not count?

We treat an attempt shorter than 2 seconds or longer than 30 seconds as a slip, such as a double tap or stepping away from the screen, and it is played again. After the third such attempt in one game, the game ends without saving.

How we calculate the comparison

The bands next to your result come from fixed thresholds that are the same for every player. The percentile is calculated from the scores of other players on this site, not from published norms, and it only appears once enough runs have been stored. The typing test has its own comparison for each language version, because the word pools differ. For the other games we pool all languages together.

Measuring conditions differ from person to person: a different mouse, a different screen, a different level of focus. So treat the comparison with others as a rough guide. The most useful number is your own history of recent attempts, which sits right next to the result.

These games are for practice and rough comparison. They are not psychological or medical diagnostics, and the result says nothing about your intelligence or your health.
