Medium Sudoku
Welcome to Medium Sudoku, the next step after Easy. Every puzzle can still be solved with singles alone, with no pairs or other candidate patterns, but the singles are harder to find: fewer cells open up at a time, so you'll often need to work out which digits a cell can still take.
Techniques You'll Need
- Hidden Singles
Finding a number that has only one possible cell left in a row, column, or box, even when that cell has other candidates
- Naked Singles
Identifying cells that have only one possible candidate remaining after elimination
- Last Remaining Cell
Finding the only empty cell left in a row, column, or box where a specific number must go
Balanced Challenge
Medium puzzles strike the perfect balance between accessibility and challenge. They're ideal for players who find Easy puzzles too straightforward but aren't yet ready for the complexity of Advanced or Hard levels. These puzzles will help you build the foundation for more advanced solving techniques.
