About medium sudoku
Medium sudoku puzzles strike the balance most solvers enjoy. With fewer starting clues than easy boards, you will need to combine scanning with a little note-taking, but the solutions stay approachable. They make a great daily puzzle for a coffee break or commute.
How to solve medium sudoku
- When scanning runs dry, pencil in candidate numbers for empty cells.
- Look for pairs — two cells in a unit that share the same two candidates.
- Work one box at a time to avoid missing an easy placement.
