The rubik's cube, the star of puzzles

The world's most famous puzzle was invented in 1974 by the Hungarian Ernö Rubik. A sculptor and professor of architecture, he came up with the brilliant idea of creating the "geometric puzzle" to teach his students the principles of 3D geometry!
Following several years of development, he obtained a patent for his invention in 1977. The Cube was made from injection-moulded acrylonitrile butadiene styrene (ABS) and nylon.

Sold, starting that year, in Hungary, the Cube soon hopped the border in 1980 and quickly became very popular. In 1982, the year of the creation of the first international Rubik's Cube championship, over 100 million cubes were sold worldwide.
A true phenomenon, an iconic object of the 80s, it managed what no other game before it had achieved: making puzzle games fun.
Its popularity waned in the mid-1980s, but it would find favour among new fans, thanks to the Internet and the rise of Geek culture. World championships are now held on a yearly basis, and the most experienced players face-off in the hopes of having the fastest time. In 2018, the world Rubik’s Cube speed record was held by Yusheng Du, a young Chinese who solved the cube in 3.47 seconds!
However, in 2019, a robot has solved the Rubik’s Cube in an incredible 0.38 seconds!!...
