Nice article, which also explains the mapping of the puzzle to an exact cover problem and how those can be solved with dangling links as in Knuth's Algorithm X.

Oh my god, take my money, please. These types of tactile puzzles are the ideal nerdsnipe for me.

Looks amazing but getting 500 errors from the payment flow and the FLUMMOX discount code doesn't work as advertised.

Very interesting, but I have a hard time differentiating the colors. The gradients seem to be there for aesthetics only, but they confuse me to no end :)

Absolutely love this. Amazing creativity!

Totally feeling like vibe-coding a web version of the game and plastering it with giant BUY THIS THING links that send people to the real thing.

Tangential, but does anyone know good places to find other physical puzzles like this? Also, recently there was an article on elastic knots I was hoping someone would productize into a novelty puzzle.
