In fact just the frustration inducing thing to tickle the first of the virtues of a programmer: "Laziness". I then wrote a solver in Python which was far more fun than solving sudokus by hand and has the advantage that I never need to solve one of the dratted puzzles again ;-)
I recommend it as an exercise for all programmers!
I didn't document that process, but I did for solving a different puzzle which you may enjoy if you need inspiration: https://www.craig-wood.com/nick/articles/snake-puzzle/
Then I created a solver in Python as well, it uses backtracking. It can solve the puzzle instantly. Never solved another sudoku puzzle ever since.
Some day I might generalize the program to larger Latin Squares (https://en.wikipedia.org/wiki/Latin_square).
I’ve recently started reading up on optimization strategies, my first attempt was pretty straightforward. It’s a fun exercise I recommend for anyone who likes solving these puzzles manually.
