How to play:

If you are not familiar with how to play Sudoku, we will explain it as best as we can.

First of all, you need to put numbers in a 9 × 9 grid. You need to make sure that the number you put in each row, column, and box (3 × 3) must be the number that is in that row, column, and box.

After you have filled in all the rows, columns, and boxes, you need to check for errors. There are four possible errors in a Sudoku puzzle, and if you find one of them, you need to start again.

If you find that there is an error, you need to use the correct number that is in that row, column, and box to fix the error.
