A Magnum Opus ROUNDABOUTS puzzle consists of a square or rectangular array of squares in which some of the
squares contain a circular roundabout. The puzzle is solved by drawing a path which passes through the center of every square without
crossing over itself until it returns to the square in which it started. The path must change direction at every roundabout, and it
must also change direction exactly once in the intervening squares between ROUNDABOUTS. There is a single unique solution which can
be found without recourse to guessing.
