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…

A small improvement: use a vowel to encode turns, and consonants to encode segment lengths. So each shape would be encoded by a "word", e.g. "bakitux". Brains have dedicated "word-processing units" and those are much faster than number-processing units.

I consistently get around 8 to 10... I get approximately the same performance if I try to use my gut to match shapes or if I mentally rotate the shapes one at a time. The focal length distortion is a bit too extreme for me. I would prefer if it the shapes were a little bit more isometric-looking.

With the current focal length distortion, shapes look as if they're a few inches from my eyeballs so it's kind of hard to visualize without counting the blocks.

IMO this would be more enjoyable if the shapes were more different morphologically, and fewer (ideally no) close pairs which differ only in the length of a segment by a single block.

After the first couple of wrong guesses (though I'm pretty sure one guess was correct - could be the bug https://news.ycombinator.com/item?id=30408567) I started to count segment lengths rather than relying on mental shape rotation.

10 shapes 12 sec/shape (2nd try, no brute-force, mobile) 16 shapes (3rd try) 18 shapes (4th try) 24 shapes (5th try, no brute-force) P.S. I had 7 years of art school in addition to engineering

I'm in the same ballpark: 21 2nd try, and 18 3rd try. I've sort of always known that I've had good spatial reasoning, and this is one way to confirm it. I tend to think about most problems spatially, even molding things like code and social relations into this medium, because it's my strongest skill. I also tend toward the hyperphantasia side of the spectrum. I'm curious if other highscorers also tend toward hyperphantasia.

If the site is recording telemetry on scores, but it would be fantastic to have a percentile rank at the end.

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.

This make is making me feel really stupid

I don’t think it’s a bug. I resorted to some guessing because I saw shapes that were similar but different only by length. But the view was obscured so I couldn’t count the blocks.
