Puzzle#86: Windoku Sudoku

on
This windoku is tricky and uses some good techniques which everybody should know. I expect experts to zip through this, however beginner may feel this hard.


Apply classic sudoku rules. Each of shaded four 3x3 regions must contain each digit from 1-9 exactly once.

    Nice one . Selecting 8 in r9c2 and 2 in r9c9 were deciding factors. Digits 1,3,9 were fixed by guess work.
