When scanning alone is not enough, use notes to track candidates. Compare the same digit across intersecting rows and boxes before making a move.
How to play Medium Sudoku
Fill every row, column and 3 × 3 box with the digits 1–9, without repeating a digit. Select a cell and enter a number, or use notes to record possibilities. Notes, undo and hints are available in the game.
