Sudoku X is the Daily Mail's daily diagonal sudoku. Besides every row, column and box, the two long diagonals must also hold each digit once.
About Sudoku X (Daily Mail)
Sudoku X is one of about thirty puzzles on the Daily Mail games page, free in the browser with ads. Each one opens on a start screen that carries the day's date, and every reader gets the same puzzle that day.
Sudoku X keeps every rule of classic sudoku and adds one: the two main diagonals of the grid must each contain every digit exactly once as well. The grid is not always the full 9x9: the puzzle for 7 October 2026 was a 6x6 grid with boxes of two rows by three columns and the digits 1 to 6. The extra constraint gives new ways in, especially where the diagonals cross.
The puzzle opens behind the Daily Mail's consent screen, where you either accept personalised ads or buy an ad-free subscription. It suits readers who like a sudoku x with their news and want a fresh one every day.

Tips
- Check the diagonals early: they often force a digit that the rows and boxes alone would not.
- The squares where the two diagonals cross sit in two diagonals at once, so their candidates narrow quickly.
- Use Note to pencil in candidates before committing a digit.
