Jigsaw Outside Sudoku Puzzle (Daily Sudoku League #200)

Jigsaw Sudoku is also known as Irregular Sudoku. This is the Sudoku type I used to fear a lot when initial I was introduced to it. However now a days I found Irregular Sudoku as very interesting Sudoku variation. One should be aware of In=Out technique of solving Irregular Sudoku which is must for solving any tough Sudoku of this type.
