Show HN: A 45x45 Connections Puzzle To Commemorate 2025=45*45

https://thomaswc.com/2025.html
2•thomaswc•1h ago
It's a a long puzzle, somewhat akin to a 2000 piece jigsaw puzzle. Solving it collectively with others is encouraged.

If you are the sort that likes rules, the rules are you can use Google or whatever external sources you like for help. View page source, however, is cheating.

Hat tip to Octagon and the TND crew for help in play testing and proposing categories.

I clicked straight through without reading your directions and I liked figuring out the puzzle of the puzzle. I really appreciate a long puzzle. This is great!

edit: Now I see that the bigger challenge is finding the small collections again after I’ve grouped a few together.
