Prismatoid polyhedra, which also includes pyramids, cupolas, frustums, and wedges. Only the great dodecahedron has been used in a commercial puzzle - the Alexander's Star.ĥ9 stellations of the icosahedron, one of which is the great icosahedron. The dodecahedron has three stellations: the small stellated dodecahedron, the great dodecahedron, That shape has appeared in the Starburst and the Dino Star. The octahedron has one stellation, called a stella octangula. The tetrahderon and cube have no stellations.
These shapes are also the result of stellation of some Platonic Solids. Have proven to be the most popular shapes, though the icosahedron is infrequently used.
(regular convex polyhedra) - tetrahedron, cube, octahedron, dodecahedron, and icosahedron. Probably won't make popular puzzles as they are difficult to handle and/or too difficult to visualize when solving. Polyhedra that are too spiky, too rounded, or too irregular might be of interest to a collector but Some have only appeared in custom puzzles. Only a few shapes have been used again and again as the basis for twisty polyhedra puzzles. Polyhedra have been studied extensively since antiquity and formally classified, based on their features, and whether they are The basic form of a "twisty polyhedron puzzle" is a polyhedronĪlthough rounded shapes are traditionally included in the class,įor example spheres, and cylinders or pucks (or "UFO"s).You can click the "_" symbol to hide it, if you'd like. This section contains several definitions. Of course, you eventually have to have them all, right? In the illustration below, I have identifiedġ0 fundamental puzzles most collectors feel every twisty collection should contain.īased on collating various folks' recommendations, I have also identified a further Many TP forum members have provided guidance. Newcomers to twisty collecting have asked for a short list of essential puzzles, I have also not attempted to show the many shape extensions of the FT cubes, including the "Crystal" shapes, Usually the mechanical differences are not apparent in photos. Also, there are many different brands and types of the conventional face-turning cubes, including speed cubes, which often turn better than the Rubik's brand version.

the "Planets" series of Crazy cubes and dodecahedrons, various bandaged cubes, and the "Bermuda" cubes - I have not attempted to show all the series members. Some puzzles are members of a series exploring variations on a theme - e.g. More continue to arrive and it is impossible to keep up. Starting in 2010, a new wave of twisty puzzles hit the market, and many custom designs made it into mass production. Mass-produced and commercially available. The illustration below shows many (not all!) of the twisty polyhedra (and some non-polyhedral) puzzles that are now or have in the past been I posted group shots of my twisty collection back in 2009 - Sandy Thompson - the most comprehensive catalogue/database, and.Jaap's Puzzle Page - Jaap Scherphuis - the best for analysis and solutions.These are the websites I consider to be reference standards for twisty puzzles:.3-Dimensional Sliding Block/Ball/Hole Puzzles.Catalogue (go there for a detailed menu).
