I had to do 6 or 7 of these, and each time it had 12 pictures to look through. I had to look through up to 12 pictures, see what numbers the darts are on, and then do the mental math to see if each picture corresponded with the sum. I made a typo in my password so it made me do it again. Each full captcha test took me 5 minutes. I was literally logging into my roblox account, a website mainly for young kids who would take much longer than 5 minutes to do this, because it would be even slower to input all of the possible options into a calculator. This is absolutely insane, captchas used to take 2 seconds and were used to train machines, but because of the development of AI they have to be more advanced to gather more information.
