Rubik's Cube - the leader in terms of sales among toys: 350 million Rubik's cubes were sold.

Many people call the rubik's cube puzzle. This is the wrong name. Correctly say Rubik's cube.

An interesting fact is mathematically proved: the number of all achievable different states of the Rubik's cube is 43 252 003 274 489 856 000.

The Rubik's Cube was recognized as Toy of the Year in 1980 and 1981.

The algorithm that collects the Rubik's cube in the minimum number of moves is called the "God’s algorithm." With the help of large-volume calculations on a computer, the mathematician Thomas Rokicki proved the sufficiency of 22 moves to build a Rubik's cube. Interestingly, Oscar Van Deventer created the largest Rubik's cube 17x17x17, unlike the standard 3x3x3.

Any combination of the Rubik's Cube can be solved in 20 or less movements.

A 16-year-old student from Los Angeles won the first world championship in Budapest in 1982, solving the cube in 22.95 seconds. Specialists can solve the puzzle in 24-28 moves.

An interesting fact, the Rubik's cube was collected by Anssi Vanhala from Finland in 36.72 seconds, and he did it with his feet.

People who are fond of high-speed assembly of the Rubik's Cube are called speedcubers.

The current speed boarding record belongs to Mats Valk from the Netherlands. He solved the puzzle in 5.55 seconds.

The largest Rubik's cube, measuring 3 meters and weighing 500 kg, is located in Knoxville, Tennessee, USA.
