Really? I couldn't seem to prove that I was human. I thought it just threw you into an infinite "prove you're human" loop at the end.
I tried scrolling down, realized I couldn't, then scrolled up to find the unfilled row at the top...
There are pictures of people checking things – a watch, and something else I can't quite see.
There are games of chess in a state of check.
There are monetary checks.
There are check boxes.
The one that almost got me was the popup with the timer that said "hurry up" but instead of a "go away" box it had a "full screen" box. I don't know how you are supposed to get rid of that box, I had to inspect element->delete node to get past it.
I did manage to finish in a little over 5 minutes.
The bottom-left corner of the box says something like "©lose 2019." If you click it, it closes.
Array.from(document.querySelectorAll('input[type=checkbox')).forEach(e => e.click)
