Jigsaw Sudoku

Jigsaw Sudoku. Boxes follow nine irregular regions, not the usual 3-by-3 grid.

How to play

Fill the 9×9 grid so every row, every column, and every 3×3 box contains the digits 1 to 9 with no repeats — the classic Sudoku rule. Jigsaw Sudoku adds one twist: Boxes follow nine irregular regions, not the usual 3-by-3 grid.
