The casino i frequent actually has long straight paths with 90 degree turns and intersections. But they are the main paths, linking you to the various haming areas, restaurants, and the hotel. If you go off the path, then you're in a maze of machine banks. Its like walking through a forest on a trail, you look to the left or the right and you can only see so far between the trees, in this case the machines, so you getna sense of depth and scale. I feel like this triggers your sense of curiosity. A desire to go off the path to explore or attempt to find a shortcut, thus luring you into the labyrinth.
