Medium Sudoku is a balanced option for players who already know the rules and want a bigger challenge than easy mode. It requires more cross-checking between rows, columns, and boxes.
When should you choose medium level?
Choose medium Sudoku when you can already solve easy puzzles without guessing and want to practice elimination techniques more carefully.
Useful strategies
- Combine row, column, and box information before filling a cell.
