Rubik's Cube

The Rubik's Cube is a 3D puzzle created by Erno Rubik in 1974. A Rubik's Cube starts off scrambled and is solved when all of the squares on each face are of the same color. Since its international launch in 1980 there have been approximately 350 million Rubik's Cubes sold. Today, about one out of every seven people alive have used a Rubik's Cube.

There are more than 43 quintillion possible scrambles and only one solution for the cube! Actually, there are 43,252,003,274,489,856,000 possibilities.

Any scramble can be solved in 20 moves or less. This is called "God's Number".

The creation of The Rubik’s Cube

Ernõ Rubik, a professor from Budapest In Hungary, wanted to help his students understand three-dimensional problems. His solution? The Rubik’s Cube!

His solid cube did things that the world hadn't seen before. It twisted and turned yet it didn’t break. Adding 54 colourful stickers to the six sides gave this amazing puzzle its iconic look. When Ernõ Rubik built his first Cube, it took him over a month to solve it.

At that time, he didn’t know that his “Magic Cube” – “Buvos Kocka” in Hungarian - would take the world by storm.
