What is Daily Mail Sudoku X?
Daily Mail Sudoku X is a variation of the standard Sudoku puzzle, distinguished by the inclusion of an extra set of constraints known as "X" rules. Unlike classic Sudoku, which requires each row, column, and 3x3 box to contain all digits from 1 to 9 without repetition, Sudoku X introduces two additional rules involving the diagonals.
Core Rules of Daily Mail Sudoku X
- Each row, column, and 3x3 box must contain all digits from 1 to 9 exactly once.
- Both main diagonals (top-left to bottom-right and top-right to bottom-left) must also contain all digits from 1 to 9 without repetition.
This added diagonal constraint increases the complexity of the puzzle, requiring solvers to consider more interrelated constraints and strategize accordingly.

Key Strategies for Solving Daily Mail Sudoku X
Successfully completing Sudoku X puzzles involves employing specific techniques that cater to the additional diagonal rules. Here are some essential strategies to master:
1. Focus on the Diagonals
- Since the diagonals are unique to Sudoku X, analyze them early to determine which numbers are missing.
- Use the process of elimination within the diagonals to narrow down candidate numbers for empty cells.
2. Cross-House Analysis
- Examine intersections between rows, columns, boxes, and diagonals to identify impossible placements.
- Identify cells where certain numbers cannot go based on the diagonal constraints, reducing candidate options.
3. Candidate Listing and Pencil Marks
- Write down possible numbers (pencil marks) in each empty cell to keep track of options.
- Regularly update candidates as new numbers are placed, especially focusing on the diagonals.
4. Advanced Techniques: X-Wing, Swordfish, and XY-Chains
- Utilize pattern-based techniques to eliminate candidates across rows, columns, and diagonals.
- These methods are particularly effective in complex Sudoku X puzzles with multiple overlapping constraints.
