Shiakaku of the Day (shikakuofthe.day)

A small puzzle game that I find to be a reasonable pastime. Author has also done rabble.se but that is only in Swedish.

I don't understand how to make a rectangle of size 5.

There’s a game on Apple Arcade called stitch if you want a much larger and more difficult version of this.

This is great. Reminds me of the "Flow Free" game on the Apple App Store.

Typo in title, should be “shikaku” (Japanese for quadrilateral).

There's a typo in the current title: Shiakaku -> Shikaku (Japanese for "square")

If you like these kind of games, there are millions of them at https://puzz.link/db/

Of course Simon Tatham’s puzzle collection includes this one. He calls it “rectangle”. You can configure the game to leave spaces around the numbers, which increases the difficulty. There’s a web based version here: https://www.chiark.greenend.org.uk/~sgtatham/puzzles/js/rect...

It occurs to me that a decent strategy on the large boards is to look for larger primes, since they are likely to only work one way

Congratulations, this is a great nerd snipe.

How long before someone makes the AI for this?

I imagine master will take a couple of hours to complete, so I didn’t even attempt it.
