There is a pretty high chance that you are interested in solving the 4x4x4 rubik's cube. The most commonly used method by speedcubers is called the reduction method. What you're basically doing is you're transforming your 4x4x4 rubik's cube into a scrambled 3x3x3. This is done by first solving every center block (consisting of four centerpieces each) and then pairing up all the 24 edgepieces, to create 12 edgepairs in total. The last step is solving the cube by any method you like, while dealing with the parity cases that can, and most likely will, accur. So let's get started!

Before you startEdit

Before you start learning how to solve the 4x4x4 rubik's cube, you must be familiar with the new notation as well as the locations used on the 4x4x4. And although it's not needed, it's highly recommended that you have a 4x4x4 rubik's cube.

Furthermore, since there are no fixed centerpieces, you do not know which side will have to become which colour from a scrambled cube. This is sometimes needed though, and that's why I have to teach you the colour scheme. This is dependent of the type of your cube though, so that makes it even more complicated.

First of all, look around your cube for any purple stickers. If you do have some, your cube is an Eastsheen cube. If not, look around the cube for the four white cornerpieces, and check the other stickers on those cornerpieces. If any of them is yellow, your cube uses the old colour scheme. If any of them is blue, your cube uses the new colour scheme.

Now for the colour schemes, they are like his (White - Yellow means that white is opposite of yellow):
Clockwize

Red, White and Blue are in a clockwize direction.

  • Eastsheen cube: White - Yellow, Green - Blue, Red - Purple and Red White and Blue are in a clockwise direction;
  • Old colour scheme: White - Blue, Green - Yellow, Red - Orange and Red White and Yellow are in a clockwise direction;
  • New colour scheme: White - Yellow, Green - Blue, Red - Orange and Red White and Blue are in a clockwise direction.

So now we can start solving the cube!
