  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...

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

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

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

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

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

  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

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

  Congratulations, this is a great nerd snipe.

  How long before someone makes the AI for this?

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