Difficulty overview
About Chaos Construction
Chaos Construction Sudoku gives you no pre-defined regions at all. Instead, you must deduce both the digit placements AND where the nine 9-cell regions are located, while satisfying all standard Sudoku row/column rules. This is the most open-ended Sudoku variant — the puzzle defines enough constraints (often through lines or other rules) to uniquely determine both the grid and the region structure.
