Rubik's 360
Rubik's 360 is a 3D mechanical puzzle released in 2009 by Ernő Rubik, the inventor of Rubik's Cube and other puzzles. Rubik's 360 was introduced on February 5, 2009 at the Nürnberg International Toy Fair ahead of its worldwide release in August. In contrast to most of Rubik's puzzles, Rubik's 360 is a physical challenge requiring manual dexterity rather than learning and memorizing algorithms. The puzzle involves moving six balls, each a different color, from a central sphere to six color-coded compartments in the outer sphere. This is done by maneuvering them through a middle sphere that only has two holes. There are three spheres that make up the puzzle. Like Rubik's Cube, Rubik's 360 has only one solution, but it cannot be solved by being broken apart. It is considered suitable for all ages and reviews described it as addictive and engaging.

Ball-in-a-maze Puzzle
Ball-in-a-maze puzzles are dexterity puzzles which involve manipulating either a maze (or labyrinth) or one or several balls so that the ball or balls are maneuvered towards a goal. Toys like this have been popular since '' Pigs in Clover'' (also spelled ''Pigs-in-clover'') was invented by Charles Martin Crandall and then patented on September 10, 1889. The game was a craze in the United States from mid-February to May 1889, at 8 000 puzzles being produced daily according to ''The Waverly Free Press''. It was played at home, on buses, in the street, parks, and even by US politicians. Sam Loyd falsely claimed to have invented it in an interview in 1891. In some versions, a wooden labyrinth is tilted using two knobs and the ball has to be navigated past a series of holes and obstacles. A magnet is used in other versions where the balls have to be manipulated rather than the maze. Another version, usually molded in transparent plastic, uses the ball as a key to opening an intern ...

2000s Toys
S, or s, is the nineteenth letter of the Latin alphabet, used in the English alphabet, the alphabets of other western European languages and other latin alphabets worldwide. Its name in English is ''ess'' (pronounced ), plural ''esses''. History Northwest Semitic šîn represented a voiceless postalveolar fricative (as in 'ip'). It originated most likely as a pictogram of a tooth () and represented the phoneme via the acrophonic principle. Ancient Greek did not have a "sh" phoneme, so the derived Greek letter Sigma () came to represent the voiceless alveolar sibilant . While the letter shape Σ continues Phoenician ''šîn'', its name ''sigma'' is taken from the letter ''Samekh'', while the shape and position of ''samekh'' but name of ''šîn'' is continued in the '' xi''. Within Greek, the name of ''sigma'' was influenced by its association with the Greek word (earlier ), "to hiss". The original name of the letter "Sigma" may have been ''san'', but due to the ea ...

Educational Toys
Educational toys (sometimes also called "instructive toys") are objects of play, generally designed for children. Educational Toys help with motivation, helping kids use their imagination while still pulling in the real world. These toys are important tools that offer news ways for kids to interact and stimulate learning. They are often intended to meet an educational purpose such as helping a child develop a particular skill or teaching a child about a particular subject. They often simplify, miniaturize, or even model activities and objects used by adults. Although children are constantly interacting with and learning about the world, many of the objects they interact with and learn from are not toys. Toys are generally considered to be specifically built for children's use. A child might play with and learn from a rock or a stick, but it would not be considered an educational toy because 1) it is a natural object, not a designed one, and 2) it has no expected educational ...

Mechanical Puzzles
A mechanical puzzle is a puzzle presented as a set of mechanically interlinked pieces in which the solution is to manipulate the whole object or parts of it. While puzzles of this type have been in use by humanity as early as the 3rd century BC, one of the most well-known mechanical puzzles of modern day is the Rubik's Cube, invented by the Hungarian architect Ernő Rubik in 1974. The puzzles are typically designed for a single player, where the goal is for the player to discover the principle of the object, rather than accidentally coming up with the right solution through trial and error. With this in mind, they are often used as an intelligence test or in problem solving training. History The oldest known mechanical puzzle comes from Greece and appeared in the 3rd century BC. The game consists of a square divided into 14 parts, and the aim was to create different shapes from these pieces. This is not easy to do. (see Ostomachion loculus Archimedius) In Iran "puzzle-lo ...

Combination Puzzles
In mathematics, a combination is a selection of items from a 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'' members has k! permutati ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Rubik's Revenge
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 Professor's Cube, 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 ea ...

Perplexus
Perplexus, originally released as Superplexus, is a 3-D ball-in-a-maze puzzle or labyrinth game enclosed in a transparent plastic sphere. By twisting and turning it, players try to maneuver a small steel ball through a complex maze along narrow plastic tracks. The maze has many steps (varying across puzzles). The number of steps ranges from 30 in the Perplexus Twist to 225 in the Perplexus 3x3 Rubik's cube Hybrid. Some levels drop the ball into a cup or a small rim to utilize its 3-D nature. Players must complete obstacles varying in difficulty to reach the end. Perplexus LLC is the manufacturer and a wholly owned subsidiary of Spin_Master, Spin Master Ltd (since 2017). History Perplexus was co-invented by college professor Michael McGinnis and toy inventors Brian Clemens and Dan Klitsner of San Francisco-based KID Group—known for inventing Bop It, HyperDash, and other game titles. McGinnis first drew pictures for 3-D labyrinths in the late 1970s. In 1999, he showed drawings ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Three-dimensional Space
In geometry, a three-dimensional space (3D space, 3-space or, rarely, tri-dimensional space) is a mathematical space in which three values ('' coordinates'') are required to determine the position of a point. Most commonly, it is the three-dimensional Euclidean space, that is, the Euclidean space of dimension three, which models physical space. More general three-dimensional spaces are called '' 3-manifolds''. The term may also refer colloquially to a subset of space, a ''three-dimensional region'' (or 3D domain), a '' solid figure''. Technically, a tuple of numbers can be understood as the Cartesian coordinates of a location in a -dimensional Euclidean space. The set of these -tuples is commonly denoted \R^n, and can be identified to the pair formed by a -dimensional Euclidean space and a Cartesian coordinate system. When , this space is called the three-dimensional Euclidean space (or simply "Euclidean space" when the context is clear). In classical physics, it serve ...
