Sudoku is a game with numbers, formed by a square with the side of 9, and on each row and column are placed the digits 1, 2, 3, 4, 5, 6, 7, 8, 9, written only one time; the square is subdivided in 9 smaller squares with the side of 3x3, which, also, must satisfy the same condition, i.e. each square to contain all digits from 1 to 9 written only once.
