I wish all captchas were like this. A lot more fun!

>npm install playcaptcha

Imagine you get pwned for trying this out in your home project and the APT escalates to your company repos and infects your company assets, and then the post mortem comes in and you have to explain this is what infected the company it stack

Time and time again, I prove that I'm human by giving this crap the finger and then visiting some other site. It's calling out a false positive and then exercising good taste.

It's nothing like a claw machine. It picked up the toys twice in two tries.

A human would be incredibly suspicious of this.

the real CAPTCHA would be having a "this is not realistic" button that only humans would press

My exact thought: this is nothing like a real claw machine.
bschwindHN•1h ago
The thing to grab is always on the front layer. Seems like an AI could be pretty easily trained to defeat this.

Also when you move the claw left and right, it "leans" in the wrong direction.

I can bypass this captcha just by using gemma4
eks391•53m ago
Yup. I could guess what needs to be grabbed without reading the prompt because it was always the front-most object. It also has the largest grab area; some of the plushies can't even be grabbed.

Fun idea though

What makes me human?

If it is DNA then why would I need a claw machine? (Note that this defnition on DNA, which in itself is mega-odd since DNA differs, would mean that via synthetic biology one could yield humans - according to such a definition. But this does not have to be correct, so the definition would be flawed.)

If it is not DNA, how else to prove it?

pinkmuffinere•51m ago
Is there reason to believe this is a good discriminator of human vs AI? I didn't see any about page, or statistic, or anything like that, but maybe I'm just missing it?

edit: The page links to [1], but [1] has none of the information I'm really looking for -- why should somebody use this tool?

Of course not. It is clearly a fun toy.

Lichess has a checkmate captcha that I think is cute.

It requires you to solve a mate-in-one puzzle to, e.g., post on the forums.

(Sorry, don't have a better link, there wasn't any non-technical I could find about it).

Reverse captcha: only robots can reprove one of the Euler problems on the fly? Statistically speaking we can round the people who can into the outlier group, right?

I'm tired of constantly having to prove I'm a human. Especially if it's trying to be lighthearted and fun on the surface, it just reminds me how Internet has fallen.
vasco•32m ago
I prove I'm a human by giving up trying to use the website. A machine would just relentlessly keep trying. You should try it.
nomel•31m ago
> it just reminds me how Internet has fallen.

phpboard added captchas back in 2004.

sevenzero•12m ago
I really like this! Also the other things you can find on the website. Cool stuff! Makes me want to get better at Frontend shenanigans.

Claude Opus 4.8 one-shotted it... I think we should gear these systems towards making the cost of abuse expensive as they will be able to get around these things more and more easily.
