Windows autoscroll makes this game too easy. This feature was introduced a very long time ago, possibly with the IntelliMouse in the year 1996. Press on the scroll wheel (considered to be middle-click) and release the button, which overlays a little scroll guide circle. Move the mouse down to begin scrolling, and don't touch anything else. Click any mouse button to stop scrolling. (Another variant is to click and hold the wheel button, move the mouse down to scroll, and release the button to stop.)

"Windows" autoscroll? My Mac has had the same behavior for as long as I can remember. Did they copy it?

How do you do this on macOS? I can't find anything under Settings > Mouse and I can't find a way of fluking it with various random gestures. I don't think I'll ever need it, I'm just curious!

It has never existed natively on Mac OS X.

TIL - after you wrote this, I just tested in Numbers, Brave, and Finder and this behavior did not work.

It seems that it only works in Firefox and I assumed it was an OS-level feature as I've used it so many times (and my most frequent need for such scrolling is the web, so I never noticed it's absent from other software)

Yes, yes, I know, but the site is designed for mobile devices and for the real pleasure of scrolling, not just cheating. Just for fun ;)
