2025 had a bunch of bits of fun mathematical trivia:
45² = 45 x 45 = 2025
Also,
9² x 5² = 2025
40² + 20² + 5² = 2025
My favourite?
1³+2³+3³+4³+5³+6³+7³+8³+9³ = 2025

#12Thomas, I love this! I vibe coded a bunch of quality of life improvements to this and put it up here: https://vessenes.github.io/2025is45x45/ . Note - you didn't license your original page; I've released my modifications under CC0 and linked back to you -- if you hate it, I'll take it down. I just thought it was fun but I wanted something that was a little easier to engage with. Quick summary of features - some font…
fyi, it appears that if you search for a category name like "sports" or "instrument" it will just show you every item for that category lol

#13The connections are too easy to the point where the main challenge for me was to remember/locate where I had stored the nodes of that category. I think the fun in a connection puzzle comes from trying to figure out what the link is that connects different nodes, and resolving any red herrings by deduction (which is what makes OnlyConnect's connection wall great and NYT's knockoff mediocre). In this one I can spot the intended category for each node without even looking at the others.

#14Wonderful game! Really, really well made, lots of fun. Might I ask, who are the Octagon and TND crew? I've seen a lot of these puzzles but nobody has ever just made a bigger connections before, brilliant!

This is great! I totally authorize anyone to copy the puzzle, as long as they link back to the original, as you did.

TND stands for Thursday Night Dinner, a Boston area potluck group that has been around since 1995.
Octagon is a friend who did a lot of the playtesting and also contributed the fabric and flowers categories.

That's so awesome. Working on my own take on this now, it's really a great puzzle!

Ha! I really should have known that last one, given that I once wrote a paper about the sum of cubes. https://dl.acm.org/doi/abs/10.5555/1378446.1378486

interesting. the javascript had a category name - I'm guessing my vibe employee added in category search as a feature.

Cool! I'd suggest you slap a CC-BY, CC-BY-SA or CC-BY-NC-SA license on it if you have a second; doesn't take long and lets everyone know your preferences.
