Hi,
Thank you very much for your advice.
I have thought and tried a lot of time to apply your advice to my puzzle.
I got some results, which was close but not what I wanted.
Attachments are images of the puzzle I tried.
The mistake I made in my puzzle is probably due to recursion.
Unfortunately, I don’t seem to have the ability to solve this.
I need a hint.
Please, can you tell me what I did wrong?
