What is Butterfly Clicking?
Butterfly clicking places one finger on the left mouse button and another on the right button, then alternates them as fast as possible. Since each button resets while the other clicks, output roughly doubles — most players reach 10–16 CPS with practice, and the technique is gentler on your arm than jitter.
Measured
Alternation rate — the share of consecutive clicks that switched between your left and right mouse buttons. Above ~80% is a true alternating butterfly; below ~60% is one-finger clicking.
Origin & gameplay use
The technique first spread through Minecraft PvP communities in the early 2010s, where it became the default competitive technique — popular enough that some servers banned mice with extra buttons used for butterfly-style clicking. It's now a staple skill across click-speed games.
Health & safety
Butterfly is generally the safest high-CPS technique: the load is split across two fingers. Still, alternate your practice between hands, and take a break if the index finger or knuckle feels sore.

How to use the Butterfly Clicking tester
STEP 1 — One finger per button
Place your index finger on the left button and your middle finger on the right button (or vice versa). Both must be in contact before you start — one wing is not a butterfly.
STEP 2 — Alternate in an even pulse
Click left, right, left, right in a steady rhythm. Because each button re-arms while the other is pressed, the two fingers can overlap and push output well past single-finger limits.
STEP 3 — Check the alternation rate
The tester tracks which button every click landed on. Above ~80% alternation is a genuine butterfly; below ~60% you're mostly clicking one button. If the rate is low, slow down and emphasize the swap between fingers.
STEP 4 — Balance both wings
Most players favor one button. Deliberately over-drive the weaker finger until the rhythm feels symmetric — balanced butterfly is both faster and less tiring, because neither finger takes the full load.
