The Dogic is an icosahedron-shaped puzzle like the Rubik's cube. It is a deep-cut puzzle: 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. ...more on Wikipedia about "Dogic"

Jessica Fridrich is the inventor of the most commonly used method for speed-solving the Rubik's Cube, better known as speedcubing. This method describes solving the cube in a layer by layer fashion. First a so called 'cross' is made on the first layer, consisting of the center piece and four edges. The first layer corners and edges of the second layer are put into their correct positions simultaneously (four pairs). The last layer is solved by first orienting and then permuting the last layer cubies using a large number of algorithms. ...more on Wikipedia about "Jessica Fridrich"
Lars Petrus (Born in 1961) currently resides in Silicon Valley, California. Petrus made his name as an internationally accomplished speed cuber in 1982 when he became the national champion of Sweden, and went on to finish fourth overall at the first official Rubik's Cube World Championships held in Budapest, Hungary. He later published his unique method, known as the Petrus system, on the internet. It has become an extremely popular method among intermediate and upper-level speed cubers, although its more recent usage has diminished considerably at the professional level due to the increased predominance of brute force algorithm-based methods. At the age of 44, Petrus continues to be a presence in a sport perennially dominated by teenagers. Petrus won the '3x3x3 Fewest Moves' category at the 2005 World Championships held November, 2005 at Lake Buena Vista, Florida, claiming the $500 purse. ...more on Wikipedia about "Lars Petrus"
Magic polyhedron is a term for a specific type of puzzle also known as twisty puzzles, the most popular of which is Rubik's Cube. The term may have originated from the original marketing name for Rubik's Cube, "Bűvös Kocka" which means "Magic Cube" in Hungarian. ...more on Wikipedia about "Magic polyhedron"

Minh Thai was a sixteen-year-old Vietnamese high school student from Los Angeles when he won the world championship in Budapest (June 1982) by unscrambling a Rubik's Cube ® in 22.95 seconds. ...more on Wikipedia about "Minh Thai"
There are many algorithms to solve scrambled Rubik's Cubes. One such method is described in Wikibooks's article How to solve the Rubik's Cube. This algorithm has the advantage of being simple enough to be memorizable by humans, however it will usually not give an optimal solution for the Rubik's Cube which only uses a minimum possible number of moves. ...more on Wikipedia about "Optimal solutions for Rubik's Cube"
Patrick Bossert at the age of 12, wrote a book, You Can Do the Cube, detailing the steps to solve Rubik's cube. It contained detailed step by step, turn by turn descriptions in order to master the puzzle. The book was a bestseller, selling 1.5 million copies. ...more on Wikipedia about "Patrick Bossert"

Rubik's Cube (originally known as the Magic Cube) is a mechanical puzzle invented in 1974 by the Hungarian sculptor and professor of architecture Ernő Rubik. It is a plastic cube comprising 26 smaller cubes that rotate around a typically unseen kernel. Each of the nine visible facets on a side of the Rubik's Cube exhibits one of six colours. When the puzzle is solved, each side of the Rubik's Cube is a different colour, but the rotation of each face allows the smaller cubes to be rearranged in many different ways. The challenge of the puzzle is to return the cube to its original state, in which each face of the cube consists of nine squares of a similar colour. ...more on Wikipedia about "Rubik's Cube"
In mathematics, the Rubik's Cube is an interesting object because it provides a tangible representation of a mathematical group. The Rubik's Cube group is defined as the set of all legal cube operations with composition as the group operation. ...more on Wikipedia about "Rubik's Cube group"
Rubik's Revenge is the 4x4x4 version of Rubik's Cube. Invented by Peter Sebesteny, the Rubik's Revenge was nearly called the Sebesteny Cube until a somewhat last-minute decision changed the puzzle's name to attract fans of the original Rubik's Cube. Unlike the original puzzle, it has no fixed facets: the centre facets (four per face) are free to move to different positions. The internal mechanics are rather different: the centre cubelets slide in grooves on an internal ball, which cannot be seen unless the puzzle is taken to pieces. The edge and corner cubelets glide on tracks formed by the edges of the centre cubelets in much the same way as in the 3x3x3 version. A new mechanism was introduced by the East Sheen company, where the mechanism is an expansion of that of the 3x3x3. ...more on Wikipedia about "Rubik's Revenge"

The Skewb is a magic polyhedron—that is, a mechanical puzzle in the style of Rubik's Cube—invented and marketed by Uwe Mèffert. Although it is cubical in shape, it differs from Rubik's construction in that its four axes of rotation pass through the corners of the cube rather than the centres of the faces. As a result, it is a deep-cut puzzle in which each twist scrambles all six faces. ...more on Wikipedia about "Skewb"
The Skewb Diamond is an octahedron-shaped puzzle similar to the Rubik's Cube. It has 14 movable pieces which can be rearranged in a total of 138,240 possible combinations. ...more on Wikipedia about "Skewb Diamond"
Speed cubing is the art of solving a Rubik's Cube as fast as possible. Solving here means to make the cube have each face be one single color. Regular cubes come in variations of 2x2x2, 3x3x3, 4x4x4, and 5x5x5. Puzzle builders try to invent new forms of permutation puzzles. Maybe the best way to learn what speedcubing actually is all about is to watch a video . In the video on this page, Shotaro "Macky" Makisumi set the (former) world record of 12.11 seconds. The current world record for a single solve of the 3x3x3 stands at 11.13 seconds, set by Leyan Lo from California. ( 14 January 2006) ...more on Wikipedia about "Speed cubing"
The Square One, also known as Back to Square One, is a variant of the Rubik's Cube, invented by Karel Hrsel and Vojtech Kopsky around 1992. Its distinguishing feature among the numerous 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. ...more on Wikipedia about "Square one (puzzle)"
