After the first batches of Rubik's Cubes were released in May 1980, initial sales were modest, but Ideal began a television advertising campaign in the middle of the year which it supplemented with newspaper advertisements. [23] At the end of 1980, Rubik's Cube won a German Game of the Year special award [24] and won similar awards for best toy in the UK, France, and the US. [25] By 1981, Rubik's Cube had become a craze, and it is estimated that in the period from 1980 to 1983 around 200million Rubik's Cubes were sold worldwide. [26] In March 1981, a speedcubing championship organised by the Guinness Book of World Records was held in Munich, [24] and a Rubik's Cube was depicted on the front cover of Scientific American that same month. [27] In June 1981, The Washington Post reported that Rubik's Cube is "a puzzle that's moving like fast food right now ... this year's Hoola Hoop or Bongo Board", [28] and by September 1981, New Scientist noted that the cube had "captivated the attention of children of ages from 7 to 70 all over the world this summer."

There are 8! (40,320) ways to arrange the corner cubes. Each corner has three possible orientations, although only seven (of eight) can be oriented independently; the orientation of the eighth (final) corner depends on the preceding seven, giving 3 7 (2,187) possibilities. There are 12!/2 (239,500,800) ways to arrange the edges, restricted from 12! because edges must be in an even permutation exactly when the corners are. (When arrangements of centres are also permitted, as described below, the rule is that the combined arrangement of corners, edges, and centres must be an even permutation.) Eleven edges can be flipped independently, with the flip of the twelfth depending on the preceding ones, giving 2 11 (2,048) possibilities.

The Rubik's Cube is a 3-D combination puzzle originally invented in 1974 [2] [3] by Hungarian sculptor and professor of architecture Ernő Rubik. Originally called the Magic Cube, [4] the puzzle was licensed by Rubik to be sold by Pentangle Puzzles in the UK in 1978, [5] and then by Ideal Toy Corp in 1980 [6] via businessman Tibor Laczi and Seven Towns founder Tom Kremer. [7] The cube was released internationally in 1980 and became one of the most recognized icons in popular culture. It won the 1980 German Game of the Year special award for Best Puzzle. As of March2021 [update], over 450million cubes had been sold worldwide, [8] [9] [ needs update] making it the world's bestselling puzzle game [10] [11] and bestselling toy. [12] The Rubik's Cube was inducted into the US National Toy Hall of Fame in 2014. [13]Cubes are the values that are obtained when a number is multiplied by itself three times. We can find cubes for any number, whether it is an integer or a fraction. The cube of a whole number (x) results in a perfect cube (x 3), such that cube root of x 3, results in x again. Thus, finding cubes is the inverse method of cube root. Cubes 1 to 50 Table I want to emphasise, our children, our fathers, our mothers, our sisters, are currently in captivity. There are people whose hearts are broken at this time, and I want to make sure that all the hostages, until the last one, will return home," he said. Taking advantage of an initial shortage of cubes, many imitations and variations appeared, many of which may have violated one or more patents. In 2000 the patents expired, and since then, many Chinese companies have produced copies, modifications, and improvements upon the Rubik and V-Cube designs.

The 11x11x11 version is the largest available NxNxN magic puzzle simulator. Just like for the 10x10x10 simulator, the deepest turn is the rotation of 5 layers at the same time. Scramble the 11x11x11 cube and try to solve it using the rotation buttons. Even if you are a speedcuber this operation will keep you busy for a while :)
