The Sudoku-X Puzzles in the Hard Sudoku series of books require advanced solving techniques. The Pocket Rocket series includes; Sudoku, Jigsaw Sudoku, Sudoku X and Jigsaw Sudoku X.
In my classic Sudoku-x puzzles, the grid is 9 cells wide and 9 cells deep. The lines of squares running horizontally are called rows, and the lines running vertically are called columns. The grid is further divided by thicker lines into nine 3 x 3 square boxes.
Much like a standard Sudoku puzzle, the blank cells must be filled with the correct numbers. However, in Sudoku-x there is one additional feature that actually makes the puzzle easier to solve, and that is the two lines of shaded squares that run from corner to corner. Each of these shaded diagonals must also contain the numbers 1 to 9.Each row, column, 3 x 3 box and shaded diagonal must end up containing all of the numbers from 1 to 9. Each number can only appear once in any row, column, 3 x 3 box and shaded diagonal.
