Logic Masters Deutschland e.V.

This is the fourth puzzle in my '3 Series'.

This was the first puzzle I created in this series. After managing to get some interesting logic out of 3 sandwiches, I set myself the challenge of only using clues that are a multiple of 3. I like how this one turned out and hope you can enjoy it too.
