Sudoku school
Short lessons from the rules to advanced techniques. Each one comes with a practice puzzle that needs exactly that technique.
Photo sudoku
Take a photo of a sudoku from a newspaper or book and play it here with notes, hints and checking. The photo is processed only on your phone and is never sent anywhere.
How to play
- Fill the empty cells so that every row, every column and every box contains each digit exactly once.
- Tap a cell, then a digit. Pencil mode is for notes and candidates.
- Made a mistake — undo. Stuck — use a hint.
- Start with a 6×6 warm-up, then move on to 9×9 and Master. Every puzzle has exactly one solution.
