We got one of those years ago. I had already written a Sudoku solver using Knuth's Dancing Links, so I modified it to find the Bedlam solutions. The program worked mostly but gave duplicates for some of the solutions. It was also fun to develop solution search criteria for placing the pieces, e.g. to get the reds all down one corner.

This is not a new solution. This article is from 2008 or earlier.

This is an old article. Would be fun to see someone write a multithreaded solver and let it run on a modern CPU.

Or, make it a LeetCode problem. Within 24 hours you’d have someone come up with a mind boggling hyper-optimized solution using tricks you didn’t even know existed.

Nice to see that this has surfaced again, it disappeared just about the same time as I was trying to solve it myself (https://simonekstrom.se/2023/12/17/puzzle-cube.html).

I refuse to enter the website until it implements https. A free Let's Encrypt certificate will do. Otherwise I don't even know if I'm reading what the author published on the site, or what a man-in-the-middle provided me.
