Description
Sudoku X — the diagonal twist that changes everything.
Crossoku is Diagonal Sudoku (also known as Sudoku X): a 9×9 grid where both main diagonals must also contain the digits 1–9 exactly once. This extra constraint creates 11 constraint regions instead of the standard 9, opening powerful solving strategies and making every puzzle feel fresh.
THE DIAGONAL DIFFERENCE • Both main diagonals are full constraint regions, just like rows, columns, and boxes • Diagonal interactions unlock techniques unavailable in standard Sudoku • Puzzles are carefully generated so the diagonal constraint is always meaningful • Same grid, a whole new layer of logic
SIX DIFFICULTY LEVELS • Easy: Gentle introduction to diagonal logic — perfect for new players • Medium: Diagonals start shaping every move • Hard: Diagonal intersections become critical solving pivots • Expert: Multi-region interactions demand precise thinking • Pro: Advanced techniques and diagonal chains test your limits • Master: The pinnacle — only the most rigorous logic survives
