About master sudoku
Master Sudoku raises the bar above Expert. The grids are stripped down further, so each deduction carries more weight and the path to the solution is longer and less obvious.
These are puzzles to sit with. Take your time, keep meticulous notes, and enjoy the slow, satisfying unlock of a genuinely tough board.
Tips
- Turn on Notes to pencil in candidates, then eliminate them as you place numbers.
- Scan one digit at a time across the whole grid to find where it fits.
- Use the Hint button to learn the next logical step, not just the answer.
