# The Magic Cube and Rubik’s Cube

In the mid-1970s, a Hungarian sculptor named Ern Rubik created the Rubiks cube, also known as the Magic Cube. In 1980, the ideal toy corporation licensed the cube and sold it to businessman Tibor Laczi and Seven Towns founder Tom Kremer. Since then, the cube has been a popular toy and collector’s item for decades.

## Erno Rubik designed the Rubik’s cube in the mid-1970s

The Rubik’s cube is one of the world’s most famous puzzles. This three-dimensional puzzle was designed by Erno Rubik in the mid-70s and has been a popular toy ever since. Its design was inspired by a structural problem that involved the movement of moving parts. The cube was a hit, and the inventor, an architect from Hungary, was awarded the Hungarian patent for it in 1975. Terutoshi Ishige, an engineer from Japan, also received the Japanese patent in 1976.

The cube’s popularity grew rapidly, and Rubik was able to secure a contract with the company Ideal Toy to sell one million cubes overseas. In 1980, the company brought Rubik to New York to attend a toy fair. However, he was not a natural salesman. The architect was shy and had a very limited command of English. However, the company needed someone to demonstrate the puzzle’s solveability.

## It has 43 quintillion combinations

The Rubik’s cube is an incredibly complex puzzle. One single cube can have a staggering 43 quintillion different combinations. In fact, the number of possible combinations is so large that, stacked two-thirds the way up, one standard-sized cube could cover the entire Earth’s surface 275 times over.

However, this number doesn’t mean that this puzzle is impossible to solve. A person can get a solution to the Rubik’s cube using an algorithm based on mathematical equations. The number of possible combinations is so large that it would take many years for a person to solve the puzzle by chance.

## It has six centre pieces

The structure of the Rubik’s cube has six central pieces, each of which is rotated by applying a force to it. This rotation allows one layer of the cube to revolve around a shaft. In the first part of the assembly process, only the centre piece is assembled.

The pieces of the Rubik’s cube are usually made of plastic. Plastic is a highly durable, rigid, and pliable material that is made through chemical reactions called polymerization. Several common thermoplastic materials are used for cubes, including ABS, nylon, and polypropylene. Other popular types of plastic include polystyrene, polyethylene, and high-impact polystyrene.

## It has eight movable cubes on the corners

A Rubik’s cube is a puzzle with 26 movable cubes and a center shaft frame. The pieces are connected to each other by axles. Some of the cubes have eight movable cubes on the corner, which can be flipped and rotated by a player to create different shapes.

## It has rivets instead of screws

Rives are a common replacement for screws in Rubik’s cube construction. The corners, edges, and center cubes all hold each other in place. Each piece has an internal tab that fits into a curved track created by the surrounding cubes. These center pieces are then fixed to the center of the cube with a rivet or spring. The rivet or spring provides pressure to keep the pieces together, yet allows flexibility so the puzzle can function smoothly.

The original Rubik’s cubes was created by Erno Rubik, a professor at the University of Budapest in Hungary. He built the cube in 1974 to teach students about three-dimensional objects. He also designed the puzzle to solve a structural problem involving moving parts. However, he was unaware that he had invented a puzzle until he scrambled one of the cubes for the first time. The invention was so successful that Rubik was soon awarded a patent in Hungary in 1975.
