A totally different style of game which also seriously stretches spatial reasoning: https://vladimirslepnev.itch.io/zigzag Inspired by Super Hexagon (remember that?), you need to repeatedly tell a "snake" which way to go with the left and right arrow keys... while the game viewport twists and rotates randomly as it continually zooms out.

Doesn't seem to work in Firefox - all it shows is a grey screen and a link to the code. Not exactly a good experience.
Very nice. One nitpick: it would be nice if the outlines turned from red to green (in addition to the other feedback already provided) to indicate a match.
Damn, that's surprisingly difficult. But I think I shouldn't be allowed to brute-force answers (that's really tempting in the current design) and I'd probably appreciate if shapes were standing still, since the movement is distracting and barely relates to the skill being tested.
great idea but the UX is very poor, it's not intuitive at all
I’d be really curious to collect gender before testing, because I feel like this is always one of those go to examples of the difference and male and female brains, would be curious to know if there is any substantial actual difference.

> The first turn can be defined as always "right" or "left," No it can’t, not in 3D... it is just a turn. You can however choose to rotate about the first segment until the turn is Right, then use this orientation for the rest. In terms of normal form and restarts, who cares? Just generate the string both ways, it’s 2n computations, choose the lowest in lexicographic order, and life is good. If you get to billions of…
Right-handed rotation is different from left-handed rotation no matter what coordinate system you choose.
You can always rotate this to (n, 0, m) and view from the +y axis looking down, and it is a right turn.
The L shape is not complex enough to be chiral, but the post is (and you are!) is claiming that you need an extra bit of information to specify “which L, the right handed one or the left handed one?” ... That is a distinctively 2D question.

IIRC Kobyashi maru incident involves a no-win situation where you change the rules of the game to create a winning situation. How are we looking at a Kobyashi maru incident here? Can you explain?
Shape rotation is often used as a proxy for G. The shapes generally progress in difficulty until they are deemed “impossible” for any human shape rotator to figure out. If you reduce the problem to counting instead of shape rotation (3D matrix multiplication) many humans can “shape rotate” to impossibly high levels of IQ
