How fast can you click?
The clicker test is the classic reflex challenge: a timer, a button, and your clicking finger. Pick a duration — 1, 5, or 10 seconds — then click the big area as many times as you can before the clock runs out. The test starts on your very first click, so there is no fumbling with a separate start button; the moment you begin, the countdown begins with you.
When time expires, the result card slides in with your score: total clicks and clicks per second (CPS), calculated to two decimal places. Every score is rated — Amazing for the genuinely quick, Fast, Average, or Slow — so you get context, not just a raw number. Your personal best per duration is tracked separately, so a great 1-second sprint never overwrites a strong 10-second endurance run.
Personal bests and a local leaderboard
Every completed test is saved to your browser's local history, capped at the twenty most recent attempts. From that history the page builds a leaderboard of your top five scores per duration, highest CPS first, with ties going to the earlier run. Watching a new score slot into the table is half the fun of a second attempt.
Space bar fans are covered too: while the timer runs, the space bar counts as a click, so you can compete with a keyboard instead of a mouse. Want the long-format challenge? Try the 10-second edition, where pacing beats raw burst. Nothing you do here leaves your device — scores are stored locally, with no account and no leaderboard shared with anyone else.
Burst speed or endurance — pick your format
The 1-second test is a pure reaction shot: one explosive second, decided by how fast your first five clicks land. The 5-second format is the community standard, long enough for technique to matter and short enough that your best is repeatable. The 10-second test is the honest one — fast starters fade, and a steady rhythm wins.
Because personal bests are tracked separately per duration, you can chase all three without one format's score overwriting another's. Most clickers find their 1-second CPS is their highest number, and their 10-second CPS the most meaningful one: it measures a speed you can actually sustain.
