FAQ:

1. Q: What happens if I make a mistake?



If you enter a number that violates the rules (e.g., repeating a number in a row), the game will usually highlight the error. You can then select the cell and correct the mistake.

2. Q: Are there difficulty levels?



While the description doesn't explicitly state it, most classic Sudoku games offer varying difficulty levels (e.g., Easy, Medium, Hard). You can usually select your preferred difficulty before starting a new puzzle.

3. Q: What if I get stuck?



Many Sudoku games provide a "Hint" feature. This might reveal a single number or highlight cells where only a few possibilities exist. Use hints strategically to keep progressing without giving away the entire solution.
