How the CPS test works

Your score is the number of clicks divided by the length of the test. The timer starts with your first click, and that click counts. In spacebar mode only real presses count: holding the key down adds nothing. Results are saved separately for each mode and length.

Questions

What is CPS?

CPS means clicks per second: the number of clicks divided by the length of the test in seconds. For example, 32 clicks in 5 seconds is 6.4 CPS.

Which test length should I pick?

1 second shows your fastest burst. 5 and 10 seconds are the usual lengths for comparing with friends. 30 to 100 seconds show how well you keep up the pace as your hand gets tired.

What are jitter, butterfly and drag clicking?

Jitter clicking means tensing your forearm so your hand shakes and clicks quickly. Butterfly clicking means tapping one button with two fingers in turn. Drag clicking means sliding a finger across the button so it bounces and registers several clicks. These can wear out a mouse faster, so check a game server's rules before using them in a match.

Does my phone count every tap?

Yes. Every finger that touches the box counts as one tap, so tapping with two fingers is allowed. Compare results on the same phone.

Why doesn't holding the spacebar count?

When you hold a key, your computer repeats it automatically. Spacebar mode only counts real presses, so holding the key down adds nothing.
