How to Play Master Sudoku

To start, select your preferred difficulty: easy, medium, or hard. The game displays a 9x9 grid where some numbers are pre-filled. Your goal is to fill in the empty cells so that each row, column, and 3x3 box contains all digits from 1 to 9 without repetition.

On desktop, use your mouse to click on any empty cell and then click the number you want to place from the number panel or press the corresponding number key (1-9) on your keyboard for quick input. Use WASD or arrow keys to navigate the grid cells efficiently. To erase a number, select the cell and press the Delete or Backspace key.

On mobile devices, tap the empty cell to select it, then tap the desired number from the on-screen keypad. You can also use swipe gestures to move between cells quickly. The hint button provides a clue if you get stuck, while the error-check feature highlights any incorrect entries.

Try to complete the puzzle as fast as possible to improve your score and beat your personal best timer. Enjoy the challenge and sharpen your logical thinking skills!
