Show HN: Cerno – CAPTCHA that targets LLM reasoning, not human biology

Unfortunately it didn't work for me with my trackball mouse. I tried multiple times. This is very likely also problematic for accessibility without another verification pathway, as assistive devices and screen readers would fail the heuristics too.

		It doesn't work for me either, I was trying multiple times and always fails, I was started to think, that maybe I'm the robot.

this game is a rage bait! Try solving on a mobile device. I don't think an elderly person would ever be able to get through this!

Even when I successfully draw a path from green to red, not touching anything it says "Sorry that's not quite right"

Was impossible for me to solve, too, on mobile.

		Same. I think an AI would have an easier time than me.

I managed once to complete the maze, but then it went into "checking" and a spinner forever.

Interesting idea but it didn't accept me the first 3-4 times I tried to draw the path on laptop trackpad - going slow led to it failing before I was finished, going fast led to messy paths that were rejected as well. Could something like this work for users with different levels of dexterity?

I am on a mobile device and I consistently find that my finger is not precise enough to draw a path; it kept complaining about path “not quite right” where my path just touched the wall a little bit. And when my finger literally obscures the screen while drawing, it essentially means I have to memorize an entire path before beginning.

This requires significant spatial thinking skills and short-term memory for a human and it is absolutely unfair for a human to expend that much cognitive power to access a website.

I did it correctly with a mouse and was rejected. Then I drew a straight line and was rejected. Then I closed the tab.

Everybody is saying it's impossible on mobile/trackpads, but I couldn't do it with a mouse either :(

I'm assuming this is an april fools joke... cause it just don't work at all as a CAPTCHA.

		The description doesn't make sense either... like "Color-word interference at maze decision points", but there are no colors (or words) at the decision points.

I‘m as confused as the other commenters, especially since it‘s unusable on an iPad.

Is the idea that if you /pass/, you're an AI?
