Thanks for the feedback!
I was already afraid that it would be possible to find other entries to the puzzle. Unfortunately I didn't have enough time to check the final puzzle to find out if it would be possible to start in an other way than I had built in. So forget about this entry, so I can use it again... :-)

Oh, schön! Pentominos. Dafür lasse ich doch glatt die Richard-Sudokus liegen, die ich mir als nächstes rausgesucht habe.

I think this puzzle is not difficult, but it might be hard to get started. There is a complete logic way into the puzzle. I have written the first logical steps in a hidden comment. I like to read about alternative starts, if you find them.
