Sudoku-X: 150 Medium and Hard Sudoku-X puzzles

By Bob Briggs

Sudoku-X is played the same way as the original 9x9 Sudoku puzzle except that an additional restriction on number placement is imposed. Every row, column and 3x3 subgrid mus contain the digits 1 through 9 as in the original game but the 2 main diagonals must also contain the digits1 through 9. The cells of the diagonals are shaded to indicate where those digits must be placed. Of course, this new rule makes the puzzles a bit more difficult to solve so if you are looking for a challenge, why not give Sudoku-X a try?
