Sudoku-X Puzzles by Dr Gareth Moore

Sudoku X A Sudoku-X puzzle is a regular Sudoku puzzle (a square grid with bold lines every third square in order to sub-divide it into nine 3 by 3 boxes) but with the addition of two additional diagonal regions, each running along the two main diagonals and generally. indicated by shaded boxes. The aim is simple: place the digits 1 to 9 into the puzzle grid so that each digit occurs once in every row, column, bold-lined 3 by 3 box and each of the two marked diagonals. The given digits in the puzzle define the puzzle in such a way that there is only one single solution, which can be reached via reasonable logical deduction. Guessing is never needed!
