The Rubik's Cube, also called Rubik's Cube, was originally a mechanical educational toy invented by Professor Ern Rubik of Budapest Institute of Architecture in 1974. There are many ways to play Rubik's Cube, such as racing, blind twisting and single twisting. And the popularity will not drop for a long time. Every year, large and small competitions are held, which is one of the most popular intellectual games.
The Rubik's cube in the usual sense refers to the third-order Rubik's cube in the narrow sense. The third-order Rubik's cube is usually a cube, made of elastic hard plastic. The conventional racing game is to disrupt the Rubik's cube and then restore it in the shortest time. The generalized Rubik's cube refers to all kinds of geometric bodies that can be disturbed and restored by rotation.
Rubik's cube, Huarong Road and French single aristocrat (independent diamond chess) are also called the three wonders of the intellectual game world. Rubik's cube was widely loved by the public in the 1980s. From 1980 to 1982, nearly 2 million Rubik's cubes were sold.
198 1 year, Patrick Porset, a little boy from England, wrote a book called You Can Restore the Rubik's Cube and sold nearly 1.5 million copies. It is estimated that in the mid-1980s, one fifth of the people in the world were playing Rubik's Cube.
Cube color matching
1, the first is the original color matching made in Hong Kong, which was first sold in the 1980s. Most products sold today are different from it, because brown has turned into orange.
The second kind is also made in Hong Kong. It is the same series of Rubik's Cube as the first one, but the color scheme is slightly different.
3. The third color scheme is made in America, and the color scheme is completely changed, from white to yellow, from blue to green, and from red to orange (the most common color scheme now).
The fourth one is made in Hungary, and its color scheme is close to the Rubik's Cube made in America.
The fifth kind is made in Japan, which is only blue and white interchangeable with the current "standard color matching". This was originally the color matching when Professor Rubik first developed the Rubik's Cube, but after it spread to Japan, Rubik listened to the opinions of color researchers and arranged a pair of colors with similar color systems on opposite sides, while Japan kept the original color matching.
