There are many approaches on how to solve the Rubik's Cube. All these methods have different levels of difficulties, for speedcubers or beginners, even for solving the cube blindfolded. People usually get stuck solving the cube after completing the first face, after that they need some help. In the following article I'm going to show you the easiest way to solve the cube using the beginner's method.
There are various puzzles that involve colored square tiles and colored cubes. Some early precursors to the Rubik's cube include devices such as the Katzenjammer and the Mayblox puzzle. The Mayblox puzzle was created by British mathematician Percy MacMahon in the early 1920s. In the 1960s, Parker Bothers introduced another cube puzzle type toy called Instant Insanity. This toy achieved a moderate level of popularity in the United States. The early 1970s brought with it a device called the Pyraminx, which was invented by Uwe Meffert. This toy was a pyramid that had movable pieces that were to be lined up according to color.
The commercial cube is composed of six fixed cubes, eight movable cubes on the corners and 12 movable cubes on the edges. Each cube is one of six colors. The Rubik's cube has red, yellow, blue, green, white, and orange colors. In its solved state, each color is on only one face. When the cube is rotated, the edges and corners move and the cube becomes scrambled. The challenge of the puzzle is to restore each cube to its original position. The cube is extremely challenging because there are slightly more than 43 quintillion (4.3 × 10 19 ) possible arrangements, and only one solution.
Erno Rubik, an architect and professor at the University of Budapest developed the first working prototype of the Rubik's cube in 1974. He received a Hungarian patent in 1975. Apparently, it was also independently designed by Terutoshi Ishige, an engineer from Japan, who received a Japanese patent in 1976. Professor Rubik created the cube as a teaching aid for his students to help them recognize three-dimensional spatial relationships. When he showed the working prototype to his students, it was an immediate hit.
Headlights are fairly simple to spot. Looking at the image, we can see on the right hand side that the orange edge has a green corner on either side of it. That is a set of headlights. The left hand side has two different colours on either side, so that is not a set of headlights. It is very important to note that a full bar (a blue edge has a blue corner on either side of it, so all three pieces are blue) is also seen as a set of headlights. This is only seen in one case of the 21 though, so you won't see it often. If you have a set of headlights on each side, ignore this part and read the section titled “The U Permutation”.

Puzzle makers have been creating problems for people to solve for centuries. Some of the earliest puzzles date back to the time of the ancient Greeks and Romans. The Chinese have a ring puzzle that is thought to have been developed during the second century A.D. This was first described by Italian mathematician Girolamo Carolano (Cardan) in 1550. When the printing press was invented, complete books of mathematical and mechanical problems designed specifically for recreation were circulated. Rubix Build
