I called it "chinnese chatpcha", back then chinnese chaptcha is so much harder than western counterpart

but now gchaptcha spam me with 5 different image if I missing a tiles for crossroad, so chinnese chaptcha is much better in my opinion

also there is variant that match the image based on shadow and different order of shape

its much better in my opinion because its use much more interactivity, solving western chaptcha is so much mind numbing now that they require you at least multiple image identification for crossroad,sign,cars etc

they want those self driving car are they

I assume both of the approaches are useless at actually stopping bots

They deter newbies but this is not a problem for experienced developers.
