I like how all the answers here are different. No one can prove they’re human anymore

Hmmm, so this just means that the variable representing the keyword was undefined, the algorithm selected 9 pictures with X <= 9, being in the proper category, the server is possibly still awaiting the proper response, now all we have to do is find the photos that match the intended Photo, given X is going to be repeated so it can match the keyword we can assume if an object is repeated with consistency it is going to be the right answer, now we have an issue, that being that the only things that are repeating are two wheel cycles, but did the computer mistake bicycles and motorcycles for the same time or was the capture trying to distinguish between bicycles and motorcycles? We can’t assume either to be correct, however given that it is a 50/50 split we can assume it is both since neither is getting preferential treatment.

So My answer from top to bottom left to right with a starting index of 0 is

{1, 2, 4, 7}

You guys really need to learn how to solve capture’s

I guess the bottom and center right images match.

All of these images show defined objects, so don’t select anything and hit verify. You would know this if you were actually human. 😌

Middle and bottom right.

They’re the only ones that aren’t a bridge, a car, a motorcycle, a bike, a traffic light, stairs, a bus, a crosswalk, or a fire hydrant.

‘undefined’ is such a mood.

Easy, none of them are undefined. Just click next

Are you sure you’re not just a robot?

Click the headphones button.

Motorcycles… it’s always motorcycles.

Well, that’d be all of the tiles—at least in this context. OP, sorry you had to find out this way.

So, click em all?

When unsure of what the Captcha is trying to learn from me, I find “Kill all humans.” is a pretty good guess what the Captcha is really after.
