How to play Sudoku
Sudoku is played on a 9x9 square grid, which is divided into 3x3 square areas. Each game starts with some of the boxes filled in with numbers ranging from 1 to 9.
You have to fill all the squares so that each number appears only once in each row, once in each column, and once in each of the areas delimited with a bold line.
