I assumed that successfully unscrambling a cube would forever remain on my bucket list, but a smart Rubik’s Cube is finally teaching me the strategies to solve one.

To solve the Rubik's cube, all you need is a slightly expensive connected cube, and time to kill.

A group of mathematicians, desperate to discover all solutions to Rubik's Cube, get free computer time from Google and reach their Holy Grail.

Tutorial for Rubik’s Cube: Android / iOS, free/$1 to remove ads A very useful guide to general solving methods, with some explanations of specific situations that I didn’t see in the other apps.

Scrambling it is much easier than solving it. But it still involves some fascinating questions, such as the number of random moves needed to consider the cube truly messed up.
