Logic Masters Deutschland e.V.

Another puzzle from way back, I think of this series as the second puzzle I ever set. The hope was to make something I could use to introduce friends to this hobby, and introduce me to setting. Each floor adds a new constraint and ramps up the difficulty a bit. The first two floors are definitely 1 star difficulty. The last 2 floors are probably 2 stars. Hope you enjoy, and thanks for playing.
