Tetraminx The PYRAMINX (/ˈpɪrəmɪŋks/ ) is a regular tetrahedron puzzle in the style of Rubik\'s Cube . It was made and patented by Uwe Mèffert after the original 3 layered Rubik's Cube Rubik's Cube by Erno Rubik Erno Rubik , and introduced by Tomy Tomy Toys of Japan (then the 3rd largest toy company in the world) in 1981.

He did nothing with his design until 1981 when he first brought it to Hong Kong for production. Uwe is fond of saying had it not been for Erno Rubik's invention of the cube, his Pyraminx Pyraminx would have never been produced [...More...]  "Tetraminx" on: Wikipedia Yahoo 

Square1 (puzzle) The SQUARE1, also known as Back to Square One and Cube 21, is a puzzle similar to the Rubik\'s Cube . Its distinguishing feature among the numerous Rubik's Cube Rubik's Cube variants is that it can change shape as it is twisted, due to the way it is cut, thus adding an extra level of challenge and difficulty. The Super Square One and Square Two puzzles have been recently introduced. The Super Square One has two additional layers that can be scrambled and solved independently of the rest of the puzzle, and the Square Two has extra cuts made to the top and bottom layer, making the edge and corner wedges the same size. The Square1 puzzle scrambled. The same puzzle in its original (solved) state [...More...]  "Square1 (puzzle)" on: Wikipedia Yahoo 

Helicopter Cube The HELICOPTER CUBE is a Rubik\'s Cube Cube like puzzle invented by Adam G. Cowan in 2005 and built in 2006. It is also in the shape of a cube , but cut differently, and twists around cube edges rather than cube faces. The purpose of the puzzle is to scramble the colors, and then restore them back to their original state of a single color per face. CONTENTS * 1 Description * 2 Solutions * 3 Number of combinations * 4 See also * 5 References DESCRIPTION Helicopter cube, scrambled The Helicopter Cube Cube is made in the shape of a cube, cut into 8 corner pieces and 24 face center pieces. Each corner piece has 3 colors, and each face center piece has only a single color. Unlike the Rubik's Cube, its faces do not rotate; rather, the pieces are scrambled by rotating around a cube edge [...More...]  "Helicopter Cube" on: Wikipedia Yahoo 

Sudoku Cube The SUDOKU CUBE OR SUDOKUBE is a variation on a Rubik\'s Cube in which the faces have numbers one to nine on the sides instead of colours.

NineColour Cube The NINECOLOUR CUBE (see below for other names) is a cubic twisty puzzle . It was invented in 2005 by Milan Vodicka and massproduced by Meffert\'s seven years later. Mechanically, the puzzle is identical to the Rubik\'s Cube Cube ; however, unlike the Rubik's Cube, which only has 6 different colours, the NineColour Cube Cube has 9 colours, with the individual pieces having one colour each.

Void Cube The VOID CUBE is a 3D mechanical puzzle similar to a Rubik\'s Cube , with the notable difference being that the center "cubies" are missing, which causes the puzzle to resemble a level 1 Menger sponge . The core used on the Rubik's Cube Rubik's Cube is also absent, creating holes straight through the cube on all three axes. Due to the restricted volume of the puzzle it employs an entirely different structural mechanism from a regular Rubik's Cube, though the possible moves are the same. The Void Cube Void Cube was invented by Katsuhiko Okamoto . Gentosha Education, in Japan, holds the license to manufacture Void Cubes.

VCube 8 The VCUBE 8 is an 8×8×8 version of Rubik\'s Cube . Unlike the original puzzle (but like the 4×4×4 and 6×6×6 cubes), it has no fixed facets: the center facets (36 per face) are free to move to different positions. The design was covered by Panagiotis Verdes Panagiotis Verdes ' patent from 2007 but Verdes Innovations SA did not produce it for sale until 2014. Other 8×8×8 cubes are produced by the Chinese companies ShengShou and YuXin. Methods for solving the 3×3×3 cube work for the edges and corners of the 8×8×8 cube, as long as one has correctly identified the relative positions of the colors — since the center facets can no longer be used for identification.

Rubik's Revenge The RUBIK\'S REVENGE (also known as the MASTER CUBE) is a 4×4×4 version of Rubik\'s Cube . It was released in 1981. Invented by Péter Sebestény, the Rubik's Revenge Rubik's Revenge was nearly called the SEBESTéNY CUBE until a somewhat lastminute decision changed the puzzle's name to attract fans of the original Rubik's Cube. Unlike the original puzzle (and the 5×5×5 cube ), it has no fixed facets: the centre facets (four per face) are free to move to different positions.

BrainTwist The HOBERMAN BRAINTWIST is a 3D mechanical puzzle designed and marketed by Chuck Hoberman 's company Hoberman Designs. The puzzle is in the same family as the Rubik\'s Cube and other puzzles that involve manipulating and scrambling colored face elements with the goal of returning them to their original order from a randomized state, commonly called twisty puzzles . This puzzle is unique in that in addition to solving one set of tetrahedral faces the puzzle can be flipped insideout through an intermediate stellated shape to reveal another (dual) tetrahedron with a set of 4 different colored faces. The puzzle also has an alternate solution in which the apices are each a uniform color.

Dodecahedron In geometry , a DODECAHEDRON (Greek δωδεκάεδρον, from δώδεκα dōdeka "twelve" + ἕδρα hédra "base", "seat" or "face") is any polyhedron with twelve flat faces. The most familiar dodecahedron is the regular dodecahedron , which is a Platonic solid Platonic solid . There are also three regular star dodecahedra , which are constructed as stellations of the convex form. All of these have icosahedral symmetry , order 120. The pyritohedron is an irregular pentagonal dodecahedron, having the same topology as the regular one but pyritohedral symmetry while the tetartoid has tetrahedral symmetry . The rhombic dodecahedron , seen as a limiting case of the pyritohedron, has octahedral symmetry . The elongated dodecahedron and trapezorhombic dodecahedron variations, along with the rhombic dodecahedra, are spacefilling . There are a large number of other dodecahedra [...More...]  "Dodecahedron" on: Wikipedia Yahoo 

Tuttminx A TUTTMINX (/ˈtʊtmɪŋks/ or /ˈtʌtmɪŋks/ ) is a Rubik\'s Cube like twisty puzzle, in the shape of a truncated icosahedron . It was invented by Lee Tutt .

Each hexagonal face contains a centre piece, 6 corner pieces and 6 edge pieces, while each pentagonal face contains a centre piece, 5 corner pieces and 5 edge pieces [...More...]  "Tuttminx" on: Wikipedia Yahoo 

Truncated Icosahedron In geometry , the TRUNCATED ICOSAHEDRON is an Archimedean solid Archimedean solid , one of 13 convex isogonal nonprismatic solids whose faces are two or more types of regular polygons . It has 12 regular pentagonal faces, 20 regular hexagonal faces, 60 vertices and 90 edges. It is the Goldberg polyhedron GPV(1,1) or {5+,3}1,1, containing pentagonal and hexagonal faces. This geometry is associated with footballs (soccer balls) typically patterned with white hexagons and black pentagons. Geodesic domes such as those whose architecture Buckminster Fuller Buckminster Fuller pioneered are often based on this structure. It also corresponds to the geometry of the fullerene C60 ("buckyball") molecule. It is used in the celltransitive hyperbolic spacefilling tessellation, the bitruncated order5 dodecahedral honeycomb [...More...]  "Truncated Icosahedron" on: Wikipedia Yahoo
