Difficulty overview
About Clone Sudoku
Clone Sudoku marks pairs of regions (clones) on the grid. Each pair of clone regions must contain exactly the same arrangement of digits — if one clone has a 3 in its top-left cell, the other clone must also have a 3 in its corresponding cell. Clone constraints create powerful symmetry-based deductions that can resolve entire regions at once.
