> a relatively simple puzzle I'm curious where the line on "relatively simple" is. Other people have already noted the tasks can be confusing if you're not an American English-speaker, and that the backup tasks for people with vision difficulties are nigh impossible. But beyond that: some of the time I have to do 1-3 Captcha pages, which I would class as relatively simple. Other times, I've gotten up to 10+ pages with what I believe was perfect accuracy. (They were fairly simple tasks like "click the stoplights", not the sometimes-ambiguous ones like "click the storefronts".) That's usually when I'm traveling, so it's correlated with slow internet. I don't know what the upper limit is, because there are very few pages I care about enough to push through 10+ rounds of Captcha, but I'd argue that "spending 3 minutes studying traffic photos with no end in sight" is way past my definition of 'simple'.
