The term labyrinth is often used interchangeably with maze, but modern scholars of the subject use a stricter definition. For them, a maze is a tour puzzle in the form of a complex branching passage with choices of path and direction; while a single-path ("unicursal") labyrinth has only a single Eulerian path to the center. A labyrinth has an unambiguous through-route to the center and back and is not designed to be difficult to navigate. -Wikipedia.org
