Cut off by the tide
The Lighthouse is the smallest world in the game. A narrow stairwell climbs to the lamp room, the keeper's cottage sits at the foot of the tower, and a cliff path runs down to the boathouse and the jetty. The storeroom holds paraffin and rope, and a walled garden tries to grow vegetables in the salt wind.
Visitors come for the view and stay because the sea will not let them leave. By the time the tide goes out, the case has to be solved.
How it plays
Two places here are outside: people are "on the Jetty" or "on the Cliff Path", never inside them, and the clues read that way. The outdoor squares carry rocks and bushes that block their cells, so the jetty and the path are often thin strips where only one or two positions are left. That makes them good places to start.
The stairwell is usually a narrow column. Once someone is placed in it, the rest of that column is closed to everyone else.
