Recaptcha contains a whole maximally obfuscated virtual machine with its own bytecode language. It measures your mouse movement, clicks, timing, cadence, hesitation, consistency, tile clicking order, etc.
replyAmbiguous tiles are deliberately placed because the behavior they elicit from humans can be used to discern them from bots.
Yes, the "correct" reaction to the ambiguous tiles is to hover a bit indecisively. You need to waste a certain minimum amount of time on the CAPTCHA. I've found that applying videogame reflexes and zapping all the tiles in a short period of time is a fail, even if they're the correct tiles.
replyI think it depends on how much it trusts your ip address / user agent. I used to use an extension, nopecha, that would just use ocr and then select all the matching boxes, and it never seemed to get flagged; but I have a lot more trouble on a vpn ip like proton.
These days I use buster to solve captchas and it works enough of the time that I don't have to fight with captchas.
replyIs buster a browser extension?
