Sudoku as a Service with Julia

I remember some activities we did at junior high math courses regarding Sudokus. I was so disappointed to see the brute-force solving solution to work perfectly fine, no need to implement human solving-strategies. It was fun nevertheless :)

I had the same slight disappointment when hacking a PostScript solver together back in 2005 (see https://chris-lamb.co.uk/posts/sudoku-solver-in-postscript)

On the positive side, a brute force approach means you can easily test for unique solutions.

That's why I could never get into Sudoku. There is no creativity in the endeavor. It's like doing math homework for fun.

Brute-force strategies rarely work well in real life Sudoku.

Really? They tend to work pretty well for me.

I use Sudoku to exercise my memory.
