Ok, a few regular readers have requested an INSANE Killer Sudoku puzzle so I had to respond.

This puzzle should be very difficult to solve. In fact, it might require some trial&error attempts to be solved. Do not attempt to solve this puzzle unless you are willing to accept that!

Hanjie puzzles are spreading around the world. Forlaget SuDoku, a publisher from Denmark has released a Hanjie book in which I am a co-author along with Svend Høgh. The book contains 126 Hanjie puzzles. It is published in Denmark only.

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.
