How to play Sudoku?
Instructions

- Fill in the cells. You can do this by clicking directly on the cell or by selecting the cell you want and pressing the numeric keypad on the right.
- When you finish filling them all, if you have done it correctly, a message congratulating you will be displayed. If you have doubts about whether you have filled the sudoku correctly while doing it, you can use the auto-check function that will notify you of possible errors you make.
If at any time you want to check your numbers, you can do so by pressing the check button. You can also show the sudoku solution or start over. Good luck!
