....kinda feels like a forum game thats actually interactive. Your reward is a new game.....omg....what have I become 0_0
(being funny, chill)

I usually just hit reset until I get the ones that disappear after clicking them, until there are no more left. Those are the only ones I begrudgingly do. If it's the bikes/motorcycles/traffic lights/stairs and you have to mark all of them containing the said thing, I refuse to participate in that exercise of futility.

It depends principally on IP address - if you are sharing with others (e.g. using a VPN or public proxy) then any code redemption (or support page access - this really stinks IMHO) will trigger a CAPTCHA (support pages use Cloudflare/hCaptcha rather than reCAPTCHA).

If you don't see them, then most likely your system has been recognised as a previous visitor (I was going to say "legitimate", but in these forums that could be a loaded term...).

That would explain a few things. My connection speed's were crap as well. Took me 3 times as long as it should have.
