Patent US 4,248,422

A maze, having two conductors, on each side of the maze path, is traversed by a conductive wand controlled by the operator. The maze is covered from view by a magnetically attractive surface which also may be made opaque. The wand includes a magnet that rests on the magnetically attractive surface to support the wand, while the wand tip engages the maze path. The path is viewed by way of a mirror increasing the skill required to negotiate the wand tip through the maze path.
