As always the case after making puzzles for a contest, I had a few unused puzzles and I would like to share them here in the portal. At the same time, I can make same extra advertisement for the contest. Participation is free, only a registration at LMI is necessary. You can solve the puzzles whenever you like in the weekend. After downloading the .pdf-file you have two hours time to submit your solutions. You can find the instruction booklet here.

@bauern: I am sure the puzzle has only one unique solution. After 66 people have solved it, and no other report of multiple solutions, I think you have overlooked something. But to be sure: can you write your complete solution in a hidden comment to this puzzle? Thanks!

That was funny. I'm not really used to those Sudokus but I went through it quite smooth.
