Click as soon as the area turns green. 5 attempts, the result is the median in milliseconds.
Reaction time is the gap between a stimulus appearing and you responding to it. What we measure here is simple visual reaction: one colour, one response, no choice between options.
Adults usually land somewhere between 200 and 300 ms, but hardware matters a lot. A mouse tends to beat a trackpad, a touchscreen adds its own delay, and even the refresh rate of your monitor plays a part. So compare your own attempts against each other first.
The median of five rounds is deliberate - one bad attempt will not wreck the score. The comparison with other players is a rough guide, not a norm.
Games are a quick comparison. The IQ test goes deeper and gives you the full picture.
The score is the median of five rounds in milliseconds, so a lower number is better. For adults, simple visual reaction usually sits somewhere between 200 and 300 ms. Getting under two hundred milliseconds is far easier with a mouse than on a touchscreen, and one freak attempt will not move the number, the median filters it out.
A gap of ten or twenty milliseconds between two runs means nothing, that is the normal spread between attempts. What is interesting is a shift that holds across several games on the same device. Treat the bands in the table as a rough split, not as a norm.
| ms | ||
|---|---|---|
| Excellent | ≤ 220 | A top time. Usually a mouse, a quiet room and full attention. |
| Fast | 221-280 | A fast reaction, above the usual spread. |
| Average | 281-350 | The band most attempts land in. |
| Slower | > 350 | A slower time. Often a touchscreen, tiredness or a distraction. |
The whole chain from eye to hand counts, and so does the hardware. A mouse tends to beat a trackpad, a touchscreen adds its own delay, and a 60 Hz monitor shows the colour change a few milliseconds later than a 144 Hz one. Add sleep, caffeine and whether you are measuring in a quiet room or on a moving train.
If you want to play better: keep your finger resting on the button, look at the middle of the area and do not try to guess when green is coming. An early click repeats the round anyway, so guessing only makes the game longer. And compare mostly your own runs on the same device, otherwise you are measuring hardware rather than yourself.
For adults, simple visual reaction usually falls somewhere between 200 and 300 ms. The exact number depends heavily on the device and the conditions, so treat it as a rough guide, not a norm.
The median of five rounds ignores one bad attempt. An average would be dragged upwards by it and the score would jump around more from run to run.
A touchscreen registers a tap with its own delay, and a finger travels further than a finger resting on a mouse button. A difference of tens of milliseconds between devices is normal.
The round is repeated and the early click does not count towards the score. Guessing does not help, it only makes the game longer.

Read moreThe 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.
