F=front wall LW=left wall RW=right wall B=bottom wall C=ceiling wall R=rear wall. Only positions that share a full side are considered adjacent!!! If a clue uses the word "faces", it is referring to positions facing each other on opposite walls (ceiling faces bottom, left wall faces right wall, rear wall faces front wall). Also, adjacency extends to other walls.
