Sudoku Jigsaw (also known as " Irregular ," " Nonomino " or " Geometric Sudoku ") is a logic-based, combinatorial number-placement puzzle. Jigsaw Sudokus are very similar to regular Sudoku puzzles. Regular 10x10 Sudoku that row and column rules apply, but instead of a 5x2 grid they are ten Jigsaw shapes.
