Friday Puzzles #197

Odd Sudoku this week - that is only odd numbers can go in shaded cells.  I don't care what Fred says, I think this is pretty hard.  Constructing this was a lot like constructing a Sudoku Islands puzzles, and I imagine is how people go about trying to construct the monstrously difficult scanraid-busting classic puzzles.  Enjoy!

Week 6:
Saturday (V day, Bram)
Sunday (Counting on line, Seungjae)

Week 7:
Monday (Equal, Christoph Seeliger)
Tuesday (Between 1 and 9, Prasanna)
Wednesday (Fortress, Bastien)

Oh, I should also mention that it's been a particular difficult week, so watch your step with these.  And if you haven't already joined the facebook group, then why not!?
