Happened to watch an episode of the new NBC game show, The Wall, which reminded me of this pachinko parlor in Tokyo. The Wall features an oversized version of the pachinko board, which operates like a vertical pinball machine. In pachinko, one or more steel balls are launched to the top of the playing field, which is filled with brass pins. Entering the field at the top, the steel balls fall freely, bouncing and careening from one pin to another, and finally entering one of several cups at the bottom. Upon entering a pachinko parlor, one is greeted with the chime-like sounds of the falling steel balls from hundreds of pachinko machines.
