A Hanjie-Sudoku hybrid puzzle!

Here is another very special puzzle – it’s an odd/even Sudoku puzzle but it also has clues on top and on the side, just the same as in Hanjie puzzles. This puzzle was provided by Clagu, our regular visitor from Korea. Thank you Clagu, it seems like a nice idea! Here are the rules: Hanjie clues (on top and on the side) give you the arrangement of odd numbers in that particular row/column. Note that the sum of Hanjie clues for each row and column is precisely 5 – that’s how many odd numbers there are between 1 and 9. 🙂 So, use those clues to mark (shade or however else you want to do it) cells that must contain ODD numbers. When you’ve done that, solve the puzzle as you would normally solve an odd/even Sudoku puzzle. Update: The puzzle provided by Clagu was invalid in more than one way. There was a problem with the Hanjie clues which was corrected, but then it turned out that the puzzle had two solutions. Sorry folks. When I get some time I will generate one such puzzle and post it.

    I have attempted to solve this, but I am stuck on the Hanjie part. Either the second row is supposed to be 1 3 1, or I am losing my mind. Can someone please set me in the right direction?

    My mind seems to be lost in the same place as Nathan. Also, I get 2 solutions; nothing to tell me what R4C3, R4C8, R6C3 or R6C8 must be.

    Susan, you are absolutely right. The puzzle has been removed because it’s invalid. So sorry for this.
