For 18 years I fiddled and got frustrated by the cube. When you are young there is lots of time to spend on this sort of thing.
At the age of 21 someone showed me the moves required to solve the cube. I was very pleased but also highly annoyed that it took 18 years for me to find the solution.
I am now 26 and I have done some research on that rigid time waster some people call a puzzle. It is way more than a puzzle!
Many people have studied the maths of the cube, hence the algorithms available on some sites that will solve any cube so long as you enter the colors in correctly.
The maths used in the cube is of a higher form that is studied at school, it is called group theory. Enough of that though!
There are two ways to do the cube. The short way, and the long way.
The long way involves completing one side first and then completing the rest of the cube, using sequences of moves that move certain blocks around. There are a few different methods and they all require you to remember sequences of moves for different situations.
Each person is different and one person might prefer one method over another, but for me the main criteria for a solution is the ease with which the solution can be remembered, so that a couple of months down the line you will still be able to do the cube without having practiced.
The short way involves hours of dedication and a good memory. Sequences of turns are memorized along with what the sequence achieves. The difference here is there are over 40 different sets of moves, and even more depending how determined you are.
