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.

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

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

astralasia12• 4 months ago

should be fixed.

didn't know this, thanks for sharing.

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.

astralasia12• 4 months ago

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.

You must be a shape rotator.

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

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

I think I have your new build(s) as I can play from the archive, but the contrast is still too low for me. Note that displays are different, so it's likely that things are more indistinct for me than for you. I've just played through the archive, and all my mistakes came from off-by-one errors because the grid lines were indistinct and I misplaced the holes.

increased the contrast, so it should be easier on the eye hopefully. Thanks again for the feedback.

Is there a way to play previous puzzles?

astralasia12• 4 months ago

I am planning on adding that feature as well in the near future, thanks for trying it out

No problem.

Advice. Make the scoring more like http://enclose.horse/

Score should be correct out of incorrect but medals for perfect, almost perfect, and some cutoff above.

I missed one fold on the hard one (but 3 points due to this), and only 1 star feels a little harsh to me.

astralasia12• 4 months ago

I added the archive feature, would love to hear your feedback on it as well

Works great very seamless.

These puzzles are great! Simple and effective.

I wonder if the engine could be adapted for origami. :)
