Today's fastest hands
Leaderboards
Leaderboards list the best scores on this site for each test: today, this week and all time, with pointer and touch kept apart.
Best scores on this site, from browsers. Submitting is optional. Your results stay on your device unless you submit a score to the Hall of Fame.
The top score on every board
Each board is one test, one mode and one kind of input. Open a test to see its top 10 for today, this week and all time. The best score on each board is listed here. If the numbers do not load, the tests still work and your results still stay on your device.

How the Hall of Fame works
The Hall of Fame is the top 10 of each board on this site. It is not a world ranking and it has no accounts. After a finished run you can submit the score, with a name if you want one, from the panel under your result.
Periods and input
Today is the current UTC day, this week is the ISO week in UTC (Monday to Sunday) and all time is every accepted score. Dates and times on a board show in your time zone; hover over one to see the UTC time. A tie ranks the earlier score first. Mouse, pen and keyboard play on the pointer boards and a finger plays on the touch boards, and the two are never mixed.
Our rules for a human run
These checks are ours, chosen by us to rule out values a person could not produce. They are not a published standard. The server works the score out again from the round times your browser sends, so a number typed into the request is not trusted. It also keeps the time between the start of a run and the submit, and refuses a run that is too short or older than 15 minutes.
| Test | What a run must show (our rules) |
|---|---|
| Reaction time test and F1 reaction test | Exactly 5 counted rounds, each between 100 and 3,000 ms, not all within 2 ms of each other, and at least 8 seconds between starting the run and submitting it. |
| Aim test, 30 targets | 30 target times, each at least 80 ms, a median of at least 150 ms, hit accuracy of at least 80%, and at least 6 seconds since the start. |
| Aim test, 30 seconds | No more than 60 hits, and at least 30 seconds since the start. |
| Chimp test | A score of 30 or less, and at least 2 seconds for each level reached. |
| Visual memory test | Level 50 or lower, and at least 1.5 seconds for each level. |
| Number memory test | 30 digits or fewer, and at least 1 second for each digit. |
| Sequence memory test | 50 steps or fewer, and at least 0.8 seconds for each step. |
A rejected run is counted by reason so we can tune the rules; nothing identifies the player. There are also limits per connection: 60 run starts and 20 accepted submissions an hour. These checks catch what a person could not do. They cannot prove that a run was played by hand, so a place here is a place among visitors, and it is not a verified record.
Scores depend on the device
A browser score is you plus the screen, the input device and the browser. A 60 Hz screen waits up to 16.7 ms for the next frame where a 144 Hz screen waits up to 6.9 ms, and a wireless mouse or a phone adds its own delay. Nothing is subtracted for any of it, so a faster setup can post a faster number from the same hand. Compare a board with your own earlier runs on the same setup before comparing yourself with a name on it. See the reaction time test for how a round is timed.
Names and moderation
A name is optional: 2 to 20 letters (any script), numbers, spaces, underscores, hyphens or dots. Web addresses, handles, slurs, profanity and words that pose as staff are refused after we normalize case, look-alike characters and repeated letters. Without a name you get an auto-name such as Adjective Animal #1234, shown to you after you submit so you can share it. We can hide an entry from the boards. To report a name, write to hello@onlinereactiontimetest.com with the board, the name and the time shown. A board shows the name, the score, the device type and the time, and nothing else about the player.
What is stored
Only what a submitted score needs, and nothing at all unless you press Submit. The privacy page lists every field in its Hall of Fame section.
Leaderboards FAQ
Are the leaderboards world records?
No. They list the best scores submitted on this site, from people's browsers. A browser score includes the screen, the input device and the browser, and no one checked the equipment. Read a place here as a place among visitors to this site, nothing wider.
Why are pointer and touch scores on separate boards?
A finger on a touch screen and a mouse go through different hardware and software, and phones can add delay of their own. One board for both would compare setups, so each score is ranked only against the same kind of input. Mouse, pen and keyboard count as pointer.
Do I have to submit my score?
No. Every test works the same without it, and nothing is sent unless you press Submit score under your result. A name is optional too; without one you get an auto-name.
How do I report a name?
Write to hello@onlinereactiontimetest.com with the board, the name and the time shown. We can hide an entry from the boards.
