Basketball is a mechanical maze, based on a mechanical concept by Mark White. Through Ed Pegg's www.mathpuzzle.com page, Oskar found Mark White's CodeWorld game, see http://www.codefun.com/CodeW.htm. Mark had discovered that four pins placed in a tetrahedral fashion could smoothly slide through dodecahedrally placed grooves in a sphere. Mark used his mechanical concept for a sort-of a combinatorial game. Mark even developed some well-working prototypes. Unfortunately, after consulting several distributors, he found that the game would be too expensive for mass production.
This maze uses the same notion and has a set of tetrahedral pins follow a dodecahedral maze in such a fashion that the basketball moves through the set of pins to the bottom of the basket. Again, this is a puzzle which would be difficult to produce any way other than by a 3D printer.
