I solved the Rubik Cube without having to look anything up for the first time today! True, I don't know the algorithm to rotate the final corner pieces once they're in position, but there is a chance that their orientation is correct once moved in place, and so I got lucky.
Once I know that algorithm I'll be able to say that I can solve the cube - nevertheless, when I was growing up, the cube was seen as incredibly hard. Solving it seemed beyond the reach of many - it's actually not, it's a few fairly easy to learn algorithms which are applied.
Still, that doesn't stop me being insanely pleased with this!
