In my opinion, the only skill you really need to solve the Rubik's Cube, is a good memory to remember patterns. Solving the cube is a series of moves to be executed in order, and repeated until a desired pattern is found, then moving on to the next set of repeating.
In 1997, Richard Korf, a professor of computer science at UCLA, said that his research showed that a Rubik's cube could be solved in a median of 18 moves, and no more than 20 should be needed. However, he was not able to prove this. The lowest provable number of moves needed to solve a Rubik's cube was 27âuntil now. A pair of computer science researchers from Northeastern University has developed a proof showing that a Rubik's cube in any configuration can be solved in 26 moves.
