Small bug: occasionally there are multiple matching pairs, although only 1 works (screenshot: https://ibb.co/JpRp0Pm ) Additionally, the auto rotation itself is mostly confusing, could be better to enable manual mouse rotation. Cool game nonetheless! Edit: The bug seems to be that shapes with different "DNA" can still be isometric in some cases: https://github.com/0xf00ff00f/rotator/blob/master/demo.cc#L4...

Ouch. Thank you so much for noticing this! Looks like I need a more robust test.

Scored 7 my first go but that was aided by one or two that were more or less had the same orientation and could spotted pretty easily.

I thought I'd be good at this since I do 3D editing all day, but apparently not. In my first try I couldn't get even one. Practicing some more I got up to 4 in a game. I wonder if this game can distinguish between people who have rich mental imagery and those who don't?

Earlier quoted context omitted.

It should work on mobile browsers (though I haven't tested yet).

Tried on Android chrome. I select two shapes which I'm pretty sure match and nothing happens. The only thing on the screen is a "code" hyperlink. Is there supposed to be a "accept" or "go" button or something?

There's no "accept" button, it should move to the next set when the two correct shapes are selected. But as someone else pointed out in this thread there may be multiple matching pairs - looking into it.

Sometimes the initial rotation hides a part of the shape. Also, I have always wondered if there's a way to translate these shapes to strings for quick "mental algorithm" matching. Something like, "5, left turn, 3, right turn..." I guess you'd need a normal form. The first turn can be defined as always "right" or "left," and subsequent turns can be right, left, up or down. The first turn that's "up" or "down," can be…

I think that's basically what I did, just without elevating the forms to anything conscious. By the end, I was matching shapes too fast to have actually counted much of anything -- some sort of consolidated memory had started.
