Sudoku Puzzle is a grid with 8 squares deep and 8 squares wide. In each square you need to enter numbers from 1 to 8. The meaning of the puzzle: use the number in each row, column and 4x2 block only once. In some sudokus main diagonals also contain the digits 1 through N. This variant is called Sudoku X ("Diagonal Sudoku"). Use the check box Diagonals for such sudokus.
