Rubik's cube solving



This page explains how to solve a 7x7x7 cube.

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

You'll potentially encounter parity problems you'll have to fix. Luckily, they are easier to
solve than the parity problems of the even cubes.

Each side is made up of 25 centers, 20 edges, and 4 corners. With 6 sides this makes for 150
centers, 120 edges, and 24 corners, for a grand total of 294 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 150 + 60 + 8 = 218 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.
