Pyramorphix
The Pyramorphix (), also called Pyramorphinx, is a tetrahedral puzzle similar to the Rubik's Cube. It has a total of 8 movable pieces to rearrange, compared to the 20 of the Rubik's Cube. Although it looks like a trivially simple version of the Pyraminx, it is an edge-turning puzzle with the mechanism identical to that of the Pocket Cube. Description At first glance, the Pyramorphix appears to be a trivial puzzle. It resembles the Pyraminx, and its appearance would suggest that only the four corners could be rotated. In fact, the puzzle is a specially shaped 2×2×2 cube. Four of the cube's corners are reshaped into pyramids and the other four are reshaped into triangles. The result of this is a puzzle that changes shape as it is turned. The original name for the Pyramorphix was "The Junior Pyraminx." This was altered to reflect the "Shape Changing" aspect of the puzzle which makes it appear less like the 2×2×2 Cube. "Junior" also made it sound less desirable to an adult cus ...

Skewb
The Skewb () is a combination puzzle and a mechanical puzzle similar to the Rubik's Cube. It was invented by Tony Durham and marketed by Uwe Mèffert. Although it is cubical, it differs from the typical cubes' construction; its axes of rotation pass through the corners of the cube, rather than the centers of the faces. There are four axes, one for each space diagonal of the cube. As a result, it is a ''deep-cut'' puzzle in which each twist affects all six faces. Mèffert's original name for this puzzle was the ''Pyraminx Cube'', to emphasize that it was part of a series including his first tetrahedral puzzle, the Pyraminx. The name Skewb was coined by Douglas Hofstadter in his '' Metamagical Themas'' column. Mèffert liked the new name enough to apply it to the Pyraminx Cube, and he also named some of his other puzzles after it, such as the Skewb Diamond. In December 2013, the Skewb was recognized as an official World Cube Association competition event. Mechanism The Sk ...

Uwe Mèffert
Uwe Mèffert (28 November 1939–30 April 2022) was a German puzzle designer and inventor. He manufactured and sold mechanical puzzles in the style of Rubik's Cube since the Cube craze of the 1980s. His first design was the Pyraminx – which he had developed before the original Rubik's Cube was invented. He created his own puzzle company and helped bring to market the Megaminx, Skewb, Skewb Diamond and many other puzzles. Puzzle history Invention of the Pyraminx In the early 1970s, Mèffert was interested in whether pyramids, cubes and other shapes might influence one's health and bio-energy flows. Mèffert constructed balsa wood polyhedra and found the gentle stroking of the apexes of the various shapes had a gentle massaging and stimulating influence and instilled a sense of peace, relaxation, and calm. After playing around with this idea for a while, he cut the solids into symmetric slices and attached them with rubber bands to a center ball. With the aid of his broth ...

Megaminx
The Megaminx or Mégaminx (, ) is a dodecahedron-shaped puzzle similar to the Rubik's Cube. It has a total of 50 movable pieces to rearrange, compared to the 20 movable pieces of the Rubik's Cube. History The Megaminx, or Magic Dodecahedron, was invented by several people independently and produced by several different manufacturers with slightly different designs. Uwe Mèffert eventually bought the rights to some of the patents and continues to sell it in his puzzle shop under the Megaminx moniker. It is also known by the name Hungarian Supernova, invented by Dr. Christoph Bandelow. His version came out first, shortly followed by Mèffert's Megaminx. The proportions of the two puzzles are slightly different. The Supernova is cut in such a way that the cuts on each face meet at the edges, forming a pentagram. Mèffert's Megaminx has somewhat wider edges relative to the corners. Speed-solving the Megaminx became an official World Cube Association event in 2003, with t ...

World Cube Association
The World Cube Association (WCA) is the worldwide non-profit organization that regulates and holds competitions for mechanical puzzles that are operated by twisting groups of pieces, commonly known as '' twisty puzzles'' (a subcategory of combination puzzles). The most famous of those puzzles is the Rubik's Cube. Since the start of the WCA there have been over 11,700 competitions. The WCA was founded by Ron van Bruchem of the Netherlands and Tyson Mao of the United States in 2004. The goal of the World Cube Association is to have "more competitions in more countries with more people and more fun, under fair and equal conditions." In 2017, they started work to become a non-profit organization and on November 20, 2017, the state of California accepted the initial registration of the World Cube Association. The organization is run by the board members. It assigns different teams and committees as well as delegates who can organize official competitions. The presence of a delegat ...

Rubik's Triamid
The Rubik's Triamid is a mechanical puzzle invented by Ernő Rubik and released in 1990 by Matchbox. The puzzle was patented in Hungary in 1991. It was re-released in 2017 at the American International Toy Fair by Winning Moves. The puzzle is similar to the Rubik's Cube in that the objective is to manipulate the puzzle until all sides are uniform in colour. The puzzle itself forms a triangular pyramid, so that there are four sides and colours. Rules The Triamid is made of ten individual pieces (each with four coloured sides) and four joining sections. The user is able to manipulate the puzzle by removing a small pyramid (of four pieces) from any of the four end points, rotate it, and reattach it. The puzzle is solved when each side of the pyramid has a single colour. The puzzle is superficially similar to the Pyraminx The Pyraminx () is a regular tetrahedron puzzle in the style of Rubik's Cube.

Tetrahedron
In geometry, a tetrahedron (: tetrahedra or tetrahedrons), also known as a triangular pyramid, is a polyhedron composed of four triangular Face (geometry), faces, six straight Edge (geometry), edges, and four vertex (geometry), vertices. The tetrahedron is the simplest of all the ordinary convex polytope, convex polyhedra. The tetrahedron is the three-dimensional case of the more general concept of a Euclidean geometry, Euclidean simplex, and may thus also be called a 3-simplex. The tetrahedron is one kind of pyramid (geometry), pyramid, which is a polyhedron with a flat polygon base and triangular faces connecting the base to a common point. In the case of a tetrahedron, the base is a triangle (any of the four faces can be considered the base), so a tetrahedron is also known as a "triangular pyramid". Like all convex polyhedra, a tetrahedron can be folded from a single sheet of paper. It has two such net (polyhedron), nets. For any tetrahedron there exists a sphere (called th ...

Dogic
The Dogic () is an icosahedron-shaped puzzle like the Rubik's Cube. The 5 triangles meeting at its tips may be rotated, or 5 entire faces (including the triangles) around the tip may be rotated. It has a total of 80 movable pieces to rearrange, compared to the 20 pieces in the Rubik's Cube. History The Dogic was patented by Zsolt and Robert Vecsei in Hungary on 20 October 1993. The patent was granted 28 July 1998 (HU214709). It was originally sold by VECSO in two variants under the names "Dogic" and "Dogic 2", but was only produced in quantities far short of the demand. In 2004, Uwe Mèffert acquired the plastic molds from its original manufacturer at the request of puzzle fans and collectors worldwide, and made another production run of the Dogics. These Dogics were first shipped in January 2005, and are now being sold by Meffert in his puzzle shop, ''Meffert's'' until September 2010 when the lack of interest for Meffert's Dogics made Uwe Meffert stop his Dogic productio ...

Professor's Cube
The Professor's Cube (also known as the 5×5×5 Rubik's Cube and many other names, depending on manufacturer) is a 5×5×5 version of the original Rubik's Cube. It has qualities in common with both the 3×3×3 Rubik's Cube and the 4×4×4 Rubik's Revenge, and solution strategies for both can be applied. History The Professor's Cube was invented by Udo Krell in 1981. Out of the many designs that were proposed, Udo Krell's design was the first 5×5×5 design that was manufactured and sold. Uwe Mèffert manufactured the cube and sold it in Hong Kong in 1983. Ideal Toy Company, Ideal Toys, who first popularized the original 3x3x3 Rubik's cube, marketed the puzzle in Germany as the "Rubik's Wahn" (German: ''Rubik's Craze''). When the cube was marketed in Japan, it was marketed under the name "Professor's Cube". Mèffert reissued the cube under the name "Professor's Cube" in the 1990s. The early versions of the 5×5×5 cube sold at Barnes & Noble were marketed under the name "Profess ... [...More Info...]       [...Related Items...]     OR:     [Wikipedia]   [Google]   [Baidu]   |
