This page is meant as a tutorial for speedsolving the Rubik's Revenge (4x4x4) Cube in very fast times. Using this centers first method I am able to transform a scrambled 4x4x4 cube into a scrambled 3x3x3 cube, with the potential for parities (we'll get there) in 40 seconds or less. Your 4x4x4 times will depend very largely on your 3x3x3 times, but you might as well transform the cube into a 3x3x3 with a very efficient method, even if your 3x3x3 step needs work. Below is an example average I took of how long it takes to solve a scrambled cube into a 3x3x3, with the potential for parity errors.
This tutorial is broken into three sections, 1) solving the centers of a scrambled 4x4x4, 2) Solving the edges after having solved the centers, and 3) fixing the parity errors that can occur in the 3x3x3 step.
For the third step, solving as a 3x3x3 cube, I will only provide parity fix algorithms, you are to supply your regular 3x3x3 solution. This tutorial is meant for you to be able to fully solve a 4x4x4 in fast times, but I will not give any 3x3x3 solving tips. Those you can find on other sites. The goal of this tutorial is to get you to be able to transform the scrambled 4x4 into a 3x3 with potentially either or both parity problems in 40 seconds or less.
*NOTE* This solution is optimized to give you fast times, whereas my beginner/intermediate solution is geared towards ease of learning the solution. If you are more interested in learning how to solve the 4x4x4 than in learning how to speed solve it then check out my other solution.
