As an off-topic, any problem similar to the Rubik's cube can actually be easily solved on the fly by splitting problem into smaller subproblems, recognizing the solvability and by realizing the revertibility of all changes done. Theoretically the subproblems are called 'orbits', the solvability guys are 'invariants' and the revertibility has a name 'inverse element'. However, with just a bit of common sense you can solve any similar form of mechanical puzzle just by straightforward logic without any artificial "internet recipes" or "magic moves".

Regarding the topic, omnis comparatio claudicat, I think I got what you were trying to say :p
