Butterfly click test

Put two fingers on the left mouse button and tap with them in turn, as fast and as evenly as you can. The timer starts with your first click and shows your clicks per second when time runs out.

Click inside the box to start. The timer begins with your first click.

How butterfly clicking works

Butterfly clicking means alternating two fingers, usually the index and middle finger, on the same button. While one finger lifts, the other presses, so the button is pressed twice as often as one finger could manage alone.

Hold the mouse so both fingers rest on the left button, one near the front and one further back.
Tap with the fingers in turn, like a quick drum roll. Keep the taps light: you only need enough force to press the switch.
Start with a short duration and focus on an even rhythm before you try to go faster.

Reading the result

Clicks counts every press of the primary button and CPS divides that by the duration you chose. The best score for each duration is stored separately from the regular CPS test, so you can compare techniques. The test cannot tell which finger pressed the button; it only sees presses.

If your count is much lower than you expect, the mouse may be merging very close presses: many mice ignore a second press that arrives within a few milliseconds of the first, to filter out switch bounce. Two fingers pressing almost together then count as one click.

Butterfly, jitter or drag?

Butterfly: two fingers, steady rhythm, usually easier to keep up for a while.
Jitter: one finger vibrated by tensing the arm; very fast in short bursts but tiring. Try the jitter click test.
Drag: friction across the button gives bursts of many clicks, and depends heavily on the mouse. Try the drag click test.

Comfort and game rules

Fast clicking for long periods tires the fingers, hand and wrist. Rest between attempts and stop if it hurts.
Some games and servers do not allow butterfly clicking, or limit how many clicks per second they accept, because it can look like an autoclicker. Check the rules where you play; this page does not change what a game accepts.

What this test is not

Your score says nothing about whether the mouse is healthy. If the mouse sends two clicks when you press once, test it with the double click test; to check every button, use the mouse test.

Questions

What is a good butterfly clicking CPS?

There is no reliable average to compare with: results depend on the mouse, your hand and the duration. Track your own best score for the same duration and mouse.

Why is my butterfly CPS lower than my normal CPS?

It usually takes practice to keep the two fingers alternating instead of pressing together. Some mice also merge presses that arrive very close together, which hides part of the second finger's clicks.

Is butterfly clicking allowed in games?

It depends on the game or server. Some forbid it or cap clicks per second; check their rules before using it.

Are my scores saved?

Only in this browser, separately for each duration and from the other click tests. Nothing is sent to a server, and you can clear them at any time.
