All Sudoku puzzles follow a consistent structure. A grid is divided into nine squares, each containing three by three cells. At the beginning of the game, two to five numbers between 1 and 9 are already entered in the cells. The more numbers that are provided, the easier the puzzle. The goal is to fill in the remaining cells with the numbers 1 to 9. The challenge: each number can only be entered once in a square (three by three) and in each horizontal and vertical row.
