How can you do this?
Have mercy with me!
Is that a Kinder Surprise egg shell in the third picture? Are the small puzzles able to fit in it?
Yes for the first question. Yes for the second with respect to the right black puzzle.
Claus showed me the second to last variant during the DCD but hasn't told me about the rest? He could have warned me!
Or I forgot it for the sake of my sanity ...
I think you have to correct the table. The slot left to B is equivalent to the slot in the upper left corner.
So far you have implemented only variants from the main diagonal, haven't you?
