📖 How to play Clone Sudoku
- The sudoku rules apply: 1 through 9 with no repeats in each row, column, and 3x3 box.
- The two regions of the same color are clones: they have the same shape and contain the same numbers, placed in the same relative position.
- Whatever you place in one square of a clone appears the same way in its twin square. Each puzzle has a unique solution.
💡 Tip: use the clones to "copy" clues from one part of the board to another. A number deduced in one region carries over immediately to its twin.
