Odd Even Sudoku

Merry Christmas to all who celebrate this day! 🙂

As a small gift for you, I’ve prepared an odd-even sudoku variation puzzle. It’s not the first odd even puzzle I ever posted, but it is the first plain odd even sudoku.

And to spice things up a little bit, this is a very difficult odd/even sudoku! It requires you to use the swordfish solving technique! Usually, odd even puzzels are quite easy, but this particular one is rather fiendish! It starts off easy, but then… well, see it for yourself! 🙂

Oh… and as you may have noticed… all puzzles are now “facebook free” and they will stay that way, for as long as those folks who do have facebook keep clicking on the “like” buttons. It is not required any more, but it would be nice if you did “like” the free puzzles you download! 🙂

Have a nice one, folks! 🙂

    I solved this puzzle with only one XWING! After putting the pencil marks it took me no more than 10 minutes to solve it! I liked very much.

      Sorry, but I took one pencil mark only —and less than two minutes to solve it!!! A very very easy puzzle!!! Think the even/odd-Sudokus are the easiest Sudokus-variants and a little bit boring! And no chance to make them really harder, like Killers, Outside, etc.

        What’s the matter… ? An “error” was shown to me… a server problem! No entrance possible…, but now I have the post twice?! Sorry!
