What is X Sudoku
Also known as Diagonal Sudoku, the rules are simple but the challenge is deep. Just like the classic game, you must fill the grid with numbers 1 to 9. However, there is a twist: The two main diagonals (forming an X shape) must also contain unique numbers from 1 to 9.
This single extra rule changes everything. It requires deeper logic, sharper memory, and more complex strategies.
