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.
