Modeling what makes paper-folding puzzles hard

astralasia: Author here, happy to answer questions about any part of this. The scoring weights are hand-tuned from playtesting, not learned from data. Would love to hear from anyone with psychometrics or spatial cognition experience.

smitty1e: By the third round, the submit button interfered with the puzzle on my S24 phone.

lifis: I don't understand what is supposed to be "hard". It seems utterly trivial to me.In reverse order of the folds, just mirror all holes across the fold line.

NooneAtAll3: something very wrong with brightness of the paper - it blends in with the background so much, it's impossible to play

astralasia: Thanks, I tried to make room for everything for all screen sizes but I guess I couldn't. I'll fix the layout.

astralasia: thanks for flagging this, the contrast is definitely too low. I'll fix this.

astralasia: should be fixed.

astralasia: You are definitely correct, and that is how I am solving all the puzzles as well. However, I've encountered many people that couldn't wrap their head around even the mirror across the fold line logic. For such people, the techniques I described help to come up with puzzles that feel "hard" for them. Thanks for giving it a try.
