- Rubik’s Cube is one of the most popular toys of all time — but not everyone can solve it.
- The colorful brain teaser was invented in the 1970s by Erno Rubik.
- Rubik was teaching architecture and design in Hungary when he created the cube to illustrate spatial relationships in 3D to his students — it took him more than a month to solve his own cube.
- In the video above, Rubik explains how the cube works.
Following is a transcript of the video.
Narrator: This is the iconic Rubik’s Cube.
A 22-year-old in Australia can solve it in a record 4.22 seconds. Others might spend hours, days, weeks, or even months trying to get all the colors to match up.

Rubik: Wake up their creativity, reminding their childhood. Complex things, if you don’t understand them, it seems complicated. If you understand them, and we know how to handle it, it became simple.
Narrator: And how it works is fairly basic. At least, according to Rubik.
Rubik: In my view it’s very simple. There are axises, to turn the axises the faces, it contains 27 different pieces. What you can see is only 26, because there is one in the middle.
Narrator: There are actually 43 quintillion possible combinations. It took Rubik more than a month to solve his own cube.
Rubik: It was, for me, it was important to prove it’s possible. I can’t say that the optimal one, but I was able to manage it and I was able to show it to people.
Narrator: Rubik didn’t consider the…
