Rubik Ernő, who is a Hungarian architectural professor, invented this cube. At first he used this cube just as teaching materials of architectural. But then he found that if stick six different color stickers on the six side and then mess up the cube, it is very difficult to return it. A few years later, this toy start to spread around the world. And this toy is named "Rubik's Cube" from Rubik Ernő.
The most basic ideas of solving the cube is called "Layer by Layer" instead of "side by side". We have to complete the first layer first, and then the second layer, and finally, the third layer. Each layer has some formulas to complete the layer. Just follow the formulas step by step, and you will return a mess cube.
Recently, there are more and more different cubes are manufactured because more and more people can solve the general Rubik's Cube, which can't satisfy the experts. Like increasing the layers up to 11 or make the shape strange to challenge those who interested in.
Rubik's Cube is really an amazing toy. It can not only kill time but also make some beautiful pattens. Hence Rubik's Cube is worth playing.
