Rubik's Cube is one efficient way to improve our spatial intelligence and considered a perfect brain training. Typically, the faces of the Cube are covered by stickers in six solid colors, one for each side of the Cube. When the puzzle is solved, each side of the Cube is a solid color. To have a good brain training is one thing, and to solve the Cube's puzzle is a different story.
Many general solutions for the Rubik's Cube have been discovered independently. The most popular method was developed by David Singmaster and published in the book Notes on Rubik's Magic Cube in 1980. This solution involves solving the Cube layer by layer, in which one layer, designated the top, is solved first, followed by the middle layer, and then the final and bottom layer. Other general solutions include corners first methods or combinations of several other methods. Good luck! Have a good brain and spatial intelligence training!
