Here’s How People Solve Rubik’s Cube Blindfolded
We've all seen the videos of the kids (and adults) solving a Rubik's cube, in mere seconds, blindfolded. I have trouble scrambling the thing up in the first place, much less solving it. Now we know how it's being done: with an algorithm.
a process or set of rules to be followed in calculations or other problem-solving operations, especially by a computer.
"a basic algorithm for division" - Google
With this algorithm, exposed on Facebook by Unknown Facts, one can, allegedly (because I haven't tried it) solve a Rubik's Cube from any stage of scramble. Watch:
So, all one has to do is remember the sequence and "voila": a solved puzzle!
