Medium Sudoku

Why play medium sudoku?

For beginners, medium level puzzles are a good progression to progress in solving techniques and an intermediate step before hard sudoku.

However, medium sudoku is a good practice for regular players looking to improve their time, and a nice relaxing time for amateurs.

For my part, when I have only a few minutes in front of me, I take the opportunity to do an easy or medium level sudoku.
