You can transit any maze by putting your hand on a wall, left or right, and just following the wall.
It may take you a while, but topologically it has to get you to an exit.
Not all walls work this way. You could end up going round and round forever if you pick a wall which is the *outside* of an isolated interior polygon, such as a simple closed rectangle.
(When I was young, I used to solve, study and create mazes.)
