How to read it: each panel is one labyrinth plate (a 7×31 grid). Dark cells are
solid metal; gaps are cut slots. The five brass pins sit at fixed heights and must always
line up with a slot in both plates. Sliding pins left/right (L/R) and the
plates up/down (U/D front, UB/DB back) walks the maze until each plate clears
the pins entirely.
