Rules of Sudoku:
Your goal is to fill in the grid with numbers between 1 and 9, abiding to the following rules:
- You can't have the same number repeated more than once in the same line (vertical or horizontal)
- You can't have the same number repeated more than once in the same box.

You win the game when the grid is complete, which means that each box, row and column has to contain all numbers between 1 and 9.
