The 10-second CPS test, or "Clicks Per Second" test, is a quick and popular way to measure your mouse-clicking speed. Generally used as a fun benchmark or even in competitive clicking games, the aim is to click as many times as you can within the span of 10 seconds. The higher the score, the faster your clicking abilities. Websites and apps that offer this test usually display a timer and a click counter, making it super easy for anyone to jump in and test their clicking prowess. It's a short burst of activity that can be surprisingly engaging and sometimes even addictive!
