@Lohnecke: You made a typo in the Loesungscode. Check the 16th digit.

Looks like Zafer will keep us busy to make sure he wins the Puzzle Design Contest :-)
@Realshaggy: Hi Christoph, I really didn't think that;) Sometimes I have lots of puzzle ideas in my mind and whenever I have spare time I try to share them with the others. Also sometimes I know that some of them are really not fascinating ones but also I want to share them hoping that someone enjoys solving them. But I'm quite sure that generating a puzzle is also very enjoyable and addictive process as solving a puzzle. And it is very big pleasure to see others solving your puzzles.
I also sent my puzzle ideas for the Puzzle Design Contest. But I think that my ideas are average and don't have aha! effect. I'm quite sure we'll see very interesting ones after the publication....
Regards,
Zafer
