4×4×4
The Rubik's Revenge (also known as the 4×4×4 Rubik's Cube) is a 4×4×4 version of the Rubik's Cube. It was released in 1981. Invented by Péter Sebestény, the cube was nearly called the Sebestény 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 (and other puzzles with an odd number of layers like the 5×5×5 cube), it has no fixed faces: the center faces (four per face) are free to move to different positions. Methods for solving the 3×3×3 cube work for the edges and corners of the 4×4×4 cube, as long as one has correctly identified the relative positions of the colours—since the center faces can no longer be used for identification. Mechanics The puzzle consists of 56 unique miniature cubes ("cubies") on the surface. These consist of 24 centres which show one colour each, 24 edges which show two colours each, and 8 corners which show three colours each. The original ...

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] |
V-Cube 8
The V-Cube 8 is an 8×8×8 version of the Rubik's Cube. Unlike the original puzzle (but like the 4×4×4 and 6×6×6 cubes), it has no fixed centers: the center facets (36 per face) are free to move to different positions. The design was covered by Panagiotis Verdes' patent from 2007 but Verdes Innovations SA did not produce it for sale until 2014. Other manufacturers released their own versions of the puzzle much earlier. 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. Mechanics The puzzle consists of 296 pieces ("Cubies") on the surface. There are also 84 movable pieces entirely hidden within the interior of the cube, as well as six fixed pieces attached to the central "spider" frame. The V-Cube 9 uses essentially the same mechanism, except that on the latter these hidden pieces (c ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
V-Cube 7
The V-Cube 7 is a combination puzzle in the form of a 7×7×7 cube. The first mass-produced 7×7×7 was invented by Panagiotis Verdes and is produced by the Greek company Verdes Innovations SA. Other such puzzles have since been introduced by a number of Chinese companies, some of which have mechanisms which improve on the original. Like the 5×5×5, the V-Cube 7 has both fixed and movable center facets. Mechanics The puzzle consists of 218 unique miniature cubes ("cubies") on the surface. Six of these (the central tiles of the six faces) are attached directly to the internal "spider" frame and are fixed in position relative to one another. The V-Cube 6 uses essentially the same mechanism, except that on the latter the central rows, which hold the rest of the pieces together, are completely hidden. There are 150 center pieces which show one color each, 60 edge pieces which show two colors each, and eight corner pieces which show three colors each. Each piece (or quintet ...

V-Cube 6
The V-Cube 6 is a 6×6×6 version of the original Rubik's Cube. The first mass-produced 6×6×6 was invented by Panagiotis Verdes and is produced by the Greek company Verdes Innovations SA. Other such puzzles have since been introduced by a number of Chinese companies, most of which have mechanisms which improve on the original. Unlike the original puzzle (but like the 4×4×4 cube), it has no fixed facets: the center facets (16 per face) are free to move to different positions. Methods for solving the 3×3×3 cube work for the edges and corners of the 6×6×6 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. Mechanics The puzzle consists of 152 pieces ("cubies") on the surface. There are also 66 pieces (60 movable, 6 fixed, and a central "spider" frame) entirely hidden within the interior of the cube. The V-Cube 7 uses essentially the same mechanism, except that o ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Pocket Cube
The Pocket Cube (also known as the Mini Cube and Twizzle) is a 2×2×2 combination puzzle invented in 1970 by American puzzle designer Larry D. Nichols. The cube consists of 8 pieces, which are all corners. History In February 1970, Larry D. Nichols invented a 2×2×2 "Puzzle with Pieces Rotatable in Groups" and filed a Canadian patent application for it. Nichols's cube was held together with magnets. Nichols was granted on April 11, 1972, two years before Rubik invented the 3×3×3 cube. Nichols assigned his patent to his employer Moleculon Research Corp., which sued Ideal in 1982. In 1984, Ideal lost the patent infringement suit and appealed. In 1986, the appeals court affirmed the judgment that Rubik's 2×2×2 Pocket Cube infringed Nichols's patent, but overturned the judgment on Rubik's 3×3×3 Cube. Group Theory The group theory of the 3×3×3 cube can be transferred to the 2×2×2 cube. The elements of the group are typically the moves of that can be executed on the ...

Hvidovre
Hvidovre is the main town in Hvidovre Municipality, Denmark. The town, a suburb of Copenhagen, is about 10 km southwest of the capital's center. It is the 2nd biggest suburb of Copenhagen, only beaten by Frederiksberg. History Hvidovre has been inhabited since prehistoric times. In 1929, a 3,500-year-old sword from the Bronze Age was excavated in Hvidovre. A farm, Ovre (Aworthe), was located in the area in about 1170 when Esbern Snare gave it to Sorø Abbey that later passed it on to Absalon, Bishop Absalon. A church was built during the Romanesque period. The name Hvidovre, meaning White Ovre, refers to the colour of the church, which was built in white chalk, as opposed to the one in Rødovre, Red Ovre, which was built in red brick. Hvidovre did not become a real village until the mid 1600s. In 1682 Hvidovre consisted of 18 farms and 14 houses without any agricultural land. Back then only a few crops were grown in the area. In 1635 it consisted of the following: 12% rye, ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Novelty Items
Novelty (derived from Latin word ''novus'' for "new") is the quality of being new, or following from that, of being striking, original or unusual. Novelty may be the shared experience of a new cultural phenomenon or the subjective perception of an individual. From the meaning of being unusual usage is derived the concept of the novelty dance (a type of dance that is popular for being unusual or humorous); the novelty song (a musical item that capitalizes on something new, unusual, or a current fad); the novelty show (a competition or display in which exhibits or specimens are in way some novel); and novelty architecture (a building or other structure that is interesting because it has an amusing design). It is also this sense that applies to a novelty item, a small manufactured adornment, toy or collectible. These, in turn are often used as promotional merchandise in marketing. The chess term, novelty, is used for a move in chess which has never been played before in a recorded ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Combination Puzzle
In mathematics, a combination is a selection of items from a set (mathematics), set that has distinct members, such that the order of selection does not matter (unlike permutations). For example, given three fruits, say an apple, an orange and a pear, there are three combinations of two that can be drawn from this set: an apple and a pear; an apple and an orange; or a pear and an orange. More formally, a ''k''-combination of a set ''S'' is a subset of ''k'' distinct elements of ''S''. So, two combinations are identical if and only if each combination has the same members. (The arrangement of the members in each set does not matter.) If the set has ''n'' elements, the number of ''k''-combinations, denoted by C(n,k) or C^n_k, is equal to the binomial coefficient \binom nk = \frac, which can be written using factorials as \textstyle\frac whenever k\leq n, and which is zero when k>n. This formula can be derived from the fact that each ''k''-combination of a set ''S'' of ''n'' membe ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Games (magazine)
''Games World of Puzzles'' is an American games and puzzle magazine. Originally the merger of two other puzzle magazines spun off from its parent publication ''Games'' magazine in the early 1990s, ''Games World of Puzzles'' was reunited with ''Games'' in October 2014. The entire magazine interior is now newsprint (as opposed to the part-glossy/part-newsprint format of the original ''Games'') and the puzzles and articles that originally sandwiched the "Pencilwise" section are now themselves sandwiched ''by'' the main puzzle pages, replacing the "feature puzzle" section (they are still full-color, unlike the two-color "Pencilwise" sections.) The recombined title assumed the same 9-issue-per-year publication schedule as the original ''Games''. ''Games'' ''Games'' () was a magazine devoted to games and puzzles and, until its 2014 merger was published by Games Publications, a division of Kappa Publishing Group. History ''Games'' debuted with its September/October 1977 issue, publi ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
