(There's a video on YouTube of Billy Mitchell doing that intentionally. You might encounter that little glitch that allows you to pass right through. If you're trapped between two monsters, just keep on going don't backtrack. So clear that area immediately when the level starts and do not go back into it. When the level starts, only one or two monsters will be wandering the maze, but if you wait too long, all four will be out and very likely will trap you there. In the third maze, clear out that inverted T-shaped island below you IMMEDIATELY. The monsters always go to the LEFT when they exit the pen in the middle, but be careful - as you probably noticed, periodically they suddenly change directions, and it could be just at the moment when they emerge from the pen. When they start alternating between blue and white, stop chasing the ghosts after eight color changes four in some levels. Easily one of the more common causes of losing a life is chasing the monsters for too long.

This is tricky to do in the second maze, though, because the two sets of tunnels are so far apart very hit-or-miss. The second one will come out after the next 100. The first one, depending on the machine, will come out after you eat a combination of dots and/or energizers totally around 67 to 72. Position yourself near a tunnel before a fruit (remember, a pretzel is a fruit!) comes out so you can grab it right away. A few tips I've figured out (I go in depth in this in my blog in various places):
