About expert sudoku
Expert Sudoku is for solvers who already know their techniques. These boards give away little and require you to chain your reasoning several steps ahead.
Expect long stretches of careful deduction and full pencil-mark grids. If you enjoy the feeling of cracking a stubborn puzzle open, this is your level.
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.
