Blackout Jigsaw Sudoku 9×9 puzzleIf you like tricky Sudoku variants, here’s one just for you! It’s a Blackout Sudoku with Jigsaw regions.

The rules are simple: in each row, column and bold-lined jigsaw region you must place 8 different digits in the range 1 to 9.  Don’t place a digit on the shaded squares.

If you prefer you can consider it as a standard jigsaw sudoku where the black cell can represent any value, and the value can be different for the row, the column and the jigsaw region.  For example the shaded square on the top row could take the place of a 7 in that row, an 8 in its column and a 2 in that jigsaw region.

Good luck! :)
