I remember an online pseudo-IQ test that had an image of an irregular 3D shape with pictographs on it, and then several 2d images of that shape “unfolded” in various different ways, with only one of those unfolded representations being correct and having the right pictographs in the right places at the right rotations.
Does this sound like the kind of test you were asking about?
Mentally visualizing where each side of the shape went when unfolding the shape was important for me in solving those problems, and I think they’d be pretty hard to solve mentally even with intense mastery of abstract algebra.
