Butterfly click test is clicking your mouse as fast as you can with two fingers, mainly using your index finger and middle finger, giving you higher clicks per second if done properly.
It is one of the best ways to test your clicking skills in which you need to put your two fingers on the same mouse button and hit the mouse with both fingers alternatively.
First, put both your fingers on the mouse right-side button and hit the mouse with one finger, and the second finger is in the air. Then you click with the second finger and put the first finger in the air. Remember one thing you have to do it fast.
You have provided 10 seconds in this butterfly click test. To click faster, try to hit more fastly in the first five seconds and then in the next 5 seconds, keep that momentum and get to the top. In the beginning, you will not get a high score, but with more and more practice, you can get to the top.
