Sudoku Master∙

- Choose a difficulty or start the Daily Challenge for a fresh puzzle each day. - Fill the grid with numbers 1–9 so each row, column, and 3x3 box contains all digits without repeats. - Use Notes to pencil in candidate numbers and narrow options as you deduce. - Enable error checking or use Undo to correct mistakes; tap Hint for logic-based guidance when stuck. - Study patterns like singles, hidden singles, pairs, and line elimination to solve efficiently. - Finish puzzles to track time, improve streaks, and advance to tougher levels and packs.
