Logic Masters Deutschland e.V.

This puzzle is inspired by Arrows and Dots and Arrows, XVs, and Dots created by kolot.

Both puzzles have similar break-ins that I intentionally avoid.
But I did notice an interesting property of one of his clues,
that is not very important there but I found it interesting to explore.

It is not necessary to solve kolot puzzles to understand this one,
nor do I give clues on how to solve them in this one.
But I recommend that you give them a try.
