|The Lazy Guard|
|Chapter||Chapter 4, Chapter 5|
The Lazy Guard is the 56th puzzle from The Curious Village.
The local museum has an exhibit that spans nine rooms, as shown in the diagram below. The entrance to the complex is marked by A, and the exit is marked by B. The security guard on duty is a bit of a loafer and wants to walk each room of the exhibit while turning as few times as possible. What is the fewest number of turns he can make while still visiting every room? As an example, the diagram below shows a course that involves six turns.
