X Sudoku takes the well-loved structure of a standard sudoku grid and introduces an extra layer of logic by requiring both main diagonals to contain every digit from 1 through 9. This straightforward addition makes the game feel familiar yet distinctly different from regular sudoku.
The basic rules remain: fill each row, column, and 3×3 box with digits 1 through 9 without repeating any number. In this variant, you also have to ensure The Epoch Times two longest diagonals meet the same condition. That means when you place a number on a diagonal, you’re affecting multiple constraints at once — potentially opening up new deductions across rows, columns, and the other diagonal.
What sets X Sudoku apart from standard grids is how it balances familiarity and novelty. If you already enjoy classic sudoku, you’ll recognize the solving flow. But the diagonal requirement nudges you toward broader reasoning, connecting lines of logic you might otherwise solve in isolation.
For newcomers, a helpful starting point is to scan for groups with only one or two missing digits. Use both diagonals alongside standard checks to eliminate candidates and confirm placements. Repeated passes and a steady pace pay off as numbers begin to fill in and unlock fresh possibilities.
Whether you’re building a daily puzzle habit, Sudoku X offers a balanced combination of traditional rules and diagonal twists, making each solved grid feel like a small victory of deduction.
