Some time ago I organized a cubing-event in the quarter and presented the ‘algorithms’ – how move-sequences are called in the cuber-scene – to solve the rubik’s cube using the corners first method based on information provided by Victor Ortega. Here I present the material I developed in order to teach the people this method.
Why yet another method to solve the cube?
You might wonder what would be the motivation to learn this / another method to solving the cube. The main objective of this corner’s first method is to learn a method, which allows you to solve the cube in much shorter times than possible using the ‘Spiegel-Method’ which has been initially published by the german magazine ‘Der Speigel’ back in 1980. Most people solve the cube using this or derivived methods, which solve the cube layer by layer.
The price you pay when applying one of these methods which are in fact ignoring the cube’s geometry (mathematical topology) is that you will need about 120 or more moves to solve the cube, since solving the last layer you need very long sequences just to permutate or swap edges or corners while simultaneously prevent scrambling the already solved previous layers.
You have two options here:
- learn an algorithm taking into account geometry/topology
- learn thousands of sequences to solve subproblems
Since I don’t fancy limitless learning by heart, I had motivation to learn this method and see how far I could take it.
After practicing for about 1 year 1-2 hours by week I managed to push it to 48 seconds to solve any cube. This is nothing compared to real cracks, who can solve any cube within 3-4 seconds. And still, the limit I reached was not induced by the algorithm itself but rather by my halve-baked motivity. So with this algorithm and good coordination one could possibly solve any cuve in 30 seconds.
Of course, if you intend to become a speed-cuber, this method is of no use. But if you, as myself, want to learn a method which is fairly fast with lowest learning-effort, the corners first method might be your choice.
Here comes the documentation of the Method as a PDF:
Here in addition I have a powerpoint presentation which I used to step through the different phases of solving the cube. However, all information required to solve the cube using corners first is also contained in the PDF above.
