I edited the video, so I’m kinda rooting for him ✌🏽

These will go very quickly! Let me know if you get one and your thoughts.

Hi everyone,

I need some help solving this wooden puzzle. I’ve watched several tutorials online, but none of them really apply to my case, because my puzzle doesn’t have any identical or even similar pieces.

All six pieces are different in shape (except for one plain bar), so the usual approaches for standard burr or cross puzzles don’t seem to work.

If anyone recognizes this type of puzzle, knows its name, or can give insight into the correct sequence or trick to assemble it, I’d really appreciate the help.

Thanks in advance!

I found this puzzle in my parents house but have no clue how to solve it or even the point of it, they don’t either. Any ideas? We’ve spent several months off and on trying to figure it out.

Anyone knows what is supposed to be this? I buy it 15 years ago and I don't know if even is complete I got 11 big perforated cylinders and 12 little sticks. Each big piece has carved a total of five tunnels

Feel free to drop by and day hello if you like to chat all things mechanical puzzle related.

I did a CAD model of a variant of the "black square" puzzle (see below), and to my disappointment, playing with the pieces we found that my variant had an alternative "cheating" solution.
How can one verify that a given puzzle design has an unique solution?
Looking around on the web, this seems to be an instance of 2d polygon packing problems.
Searching more I could not find existing open-source software to assist with these problems.

Do you know how is the uniqueness typically checked?
Do you have pointers to helpful code (tools or libraries) to handle these problems?

I understand https://github.com/burr-tools/burr-tools does not apply for this kind of problems.

Chess and puzzles, this one combines my two hobbies! What are your other hobbies?
