TYPES OF CUBES

There are many types of rubik's cubes, but we are only going to explain the most important.

There are the typical cubes like 1x1, 2x2, 3x3, 4x4... But there are also some strange cubes like the Megaminx.

This is the 11x11 Rubik's cube. It is formed by 144 stickers of six different colours.

Here there is the Megaminx, a octagon cube with ten stickers in every face.

There also some pyramids, like the Pyramix or the Pyramorphix.

This are the strangest cubes of rubik: the mirror (like the 3x3 but deformable) and the skewb curby.

And finally he put the the most complicated rubrik’s cube of the world and the easiest one. We don’t know the name of the first cube, but it’s like the MF8 Petaminx multiplied 3 times. The other is the 1x1 cube. 

CLASSIC CUBE

In a classic Rubik's Cube (3x3x3), there are six faces covered by nine stickers, each of one of six colours: white, red, blue, orange, green and yellow. It is the most common cube.

Here we leave a video of how to solve a rubik's cube:

RUBIK'S CUBE HISTORY

Rubik's Cube is a 3D puzzle invented in 1974 by Erno Rubik, a Hungarian architect. Originally was called the Magic Cube, but in 1980 Erno changed the name to Rubik's Cube.

The Rubik's Cube is considered the world's bestselling toy, and in January 2009, 250 had been sold worldwide.

Although the Rubik's Cube reached its height of popularity in the 1980s, is is still known and used. Since 2003, the World Cube Association, has organised competitions worldwide and kept the official world records.
