I can't seem to find the end condition for the Maze demo. There is no 'goal_reached?'

There isn't. I had to enclose the algorithm in a while (true) loop and if you reach the goal the program stops automatically. Here is a screenshot: http://imgur.com/0mape

When I solved it, the program just stopped running.
