The Rubik's Cube, also known as the Rubik's Cube, is a mechanical educational toy first invented in 1974 by Professor Erno Rubik at the Budapest School of Architecture in Hungary. The Rubik's Cube has a variety of gameplay methods such as racing, blind twisting, and single twisting. Its popularity has not declined for a long time. Competitions of various sizes are held every year. It is one of the most popular intellectual games.

Early attempts
In March 1970, Larry Nichols invented the "Puzzle with Pieces Rotatable in Groups" and applied for a Canadian patent. It was a 2×2×2 Rubik's Cube, but Each block is held together by magnets. Obtained (English) U.S. patent in 1972, two years earlier than Professor Rubik's third-order Rubik's Cube.
Start
Rubik Erno is a Hungarian professor of architecture and sculpture. In order to help students understand the composition and structure of the space cube, he made it himself The prototype of the first Rubik's Cube was created, which was inspired by the sand in the Danube River.
In 1974, Professor Rubik invented the first Rubik's Cube (called Magic Cube at the time) and received Hungarian patent number HU170062 in 1975, but did not apply for an international patent.
The first Rubik's cubes were sold in toy stores in Budapest in 1977. Unlike Nichols' Rubik's Cube, Professor Rubik's parts snap together like tenons and are not easily separated by external force, and can be made of any material.
