Mazes on Polyhedra
Mazes on Polyhedra
Trace the shortest path between two given points on the subfaces of a polyhedron (starting from the black point and ending at the gray point—the black point itself constitutes the first step in a path). The length of a path is the number of subfaces, including the first and the last. You can move from face to face as long as you do not cross a red tube.
