Sudoku Box-Jigsaw 9×9 1 puzzleI haven’t posted a puzzle for a good while, so I thought it was time to fix that with this Box-Jigsaw Sudoku puzzle.

The puzzle combines regular Sudoku with Jigsaw Sudoku. Just place 1 to 9 once each into all of the nine rows, columns, 3×3 boxes (indicated by both shaded and unshaded background areas) and bold-lined jigsaw regions.
