Take your Sudoku skills further with 250 Medium Sudoku X puzzles created for intermediate solvers
Sudoku X-also known as Diagonal Sudoku-follows the familiar rules of classic 9 9 Sudoku with one additional requirement. Fill every row, column, and 3 3 region with the numbers 1 through 9 without repetition. In addition, both main diagonals-forming an X across the grid-must also contain every number from 1 through 9 exactly once.
This extra rule creates new logical connections and offers a more engaging solving experience for players who are ready to progress beyond the beginner level.
