Rubik's cube solving



This page explains how to solve a 4x4x4 cube.

Every cube of higher order than 3x3x3 involves reducing the cube to a 3x3x3 cube, and then
solving for that.

The even cubes are initially easy to solve, but you'll potentially encounter parity problems
you'll have to fix. For the 4x4x4 there are 5 possible parity problem states. Fortunately, you
only need to remember 3 series of moves, where 2 of them resemble each other closely.
Unfortunately, there is one parity problem that involves very difficult to understand/remember
steps.

Each side is made up of 4 centers, 8 edges, and 4 corners. With 6 sides this makes for 24
centers, 48 edges, and 24 corners, for a grand total of 96 faces. Each center is alone, each edge
is paired with 1 other edge, and each corner is paired with 2 other corners. This makes for a
grand total of 24 + 24 + 8 = 56 blocks.

The pictures show you how to go about solving the cube. The solution assumes you have at least
some basic knowledge of how to handle the cube, so not all of the basic steps are shown. Make
sure you always have the exact correct orientation or the supplied moves will not work properly.

Remember to first check the general instructions page if you're new to my solutions.
