World leaderboard
The ten fastest times currently stored in the world ranking, from fastest to slowest. The list updates when a new qualifying result is submitted. The game itself shows only the top three.

| 1st | 106 ms | — |
| 2nd | 119 ms | +13 ms |
| 3rd | 121 ms | +15 ms |
| 4th | 154 ms | +48 ms |
| 5th | 155 ms | +49 ms |
| 6th | 156 ms | +50 ms |
| 7th | 222 ms | +116 ms |

How a time gets on this list
There is no sign-up and no submission form. When you finish a round faster than the slowest time currently on the board, your score is sent automatically and the ranking updates. Nothing else is sent with it — no name, no e-mail, no identifier. The list is a list of numbers, which is why there is no column for who set them.
Validation
Submissions below 100 ms are rejected. That threshold is not arbitrary: nerve conduction, motor command and muscle activation put the floor for a simple visual reaction at roughly 100–120 ms, which is why competitive athletics treats any sprint start under 0.100 s as a false start rather than a fast reflex. Anything quicker on a click test is anticipation or interference, not reaction. The reasoning is set out in full on how the measurement works.
Times above 5000 ms are also rejected — at that point the round has stopped measuring reflexes and started measuring whether someone walked away from the keyboard.
Why the top times are so fast
A global leaderboard collects the extreme tail of thousands of attempts. Even if every single player is honest, the fastest recorded number is a combination of a genuinely quick person, good hardware, and one attempt where they happened to be starting to move just as the colour changed. Do not treat the number at the top as a target — compare yourself against the typical ranges instead, and against your own history.
