I don’t know if Rockstar Social Club dice CAPTCHA is still around, but about half a year ago I’ve had an opportunity to experience it. That CAPTCHA required you to select one image out of six in which two displayed dice would add up to a certain number. To pass the test, you had to do this 10 times in a row, making no mistakes. The worst part was that it didn’t even tell you that you failed; it restarted the whole thing only when you finished selecting the last 10th image.
