Frequently Asked Questions
How do I play Sudoku Master?
Pick a mode, then fill the grid so each row, column, and sub-grid contains each digit exactly once. Select a cell and choose a digit from the on-screen palette. Use Hint/Undo/Erase/Reset when needed.
What does the mistakes limit mean?
Each mode has a maximum mistakes count (shown like “0 / X”). If you reach the limit, the run ends. Choosing an easier mode gives you more allowed mistakes.
How do hints work?
Select an empty cell, then tap Hint to place a correct digit for that cell. Hints are limited per run, and the remaining count is shown on the Hint button.
What if I get stuck?
Use Hint to place a correct digit for the currently selected cell, or use Undo/Erase to back up and try a different approach. Start with areas that have fewer empty cells to make progress faster.
Is Sudoku Master free to play?
Yes. Sudoku Master is completely free to play online—no downloads, no installs, and no account required.
Can I play Sudoku Master on mobile?
