From time to time, my kids ask me to solve a Rubik’s cube for them.
I still no how to solve the first 2 layers of the cube. Having once, a long time ago, implemented a virtual Rubik’s Cube app with an automatic solving functionality, I still can remember that part of the algorithm.
But to solve the last layer of the cube, I always need to look up the solution. Here’s a website (in German) that explains the solution with nice intuitive visuals: https://www.keks.de/wuerfel/
From now on I know where to find the solution without having to Google it.
