3x3x3 Blindfolded Solution
Difficulty: 3/5
Solving a Rubik’s cube blindfolded is not nearly as hard as you think it is. At first when I heard about solving a Rubik’s cube blindfolded, I thought it would be impossible, but there are actually several methods to solving a Rubik’s cube blindfolded using a clearly defined sequence of moves. You absolutely must be able to do the 3x3x3 Beginner’s Solution before you attempt the 3x3x3 Blindfolded Solution. There are only four steps: corner orientation, edge orientation, corner permutation, and edge permutation. That’s it. These steps probably sound familiar because they were the last four steps in the 3x3x3 Beginner’s Solution. However, in the 3x3x3 Beginner’s Solution, you are only orienting and permuting the last layer of the cube. For the 3x3x3 Blindfolded Solution, you are orienting and permuting every piece on the cube, AND you are doing all of it with your eyes closed. It sounds impossible to do, but it is actually not that difficult. The ONLY thing you ever do when solving a Rubik’s cube blindfolded is move a certain piece to a certain spot, do a certain algorithm, and then move that piece back to its original spot. The only problem is, you do that about thirty times (sometimes even more) each time you solve the cube blindfolded, and you need to memorize all of thirty of them before you close your eyes. Before we get started, I am going to explain the difference between orientation and permutation. Here’s a quick definition of each term. Orientation is the way a piece is positioned in a certain location and permutation is where a certain piece is located. Here’s an analogy to help you further understand the difference between orientation and permutation. Let’s say you have a classroom with several desks all facing the front of the classroom. Permutation is the location of the desk, and orientation is the way the desk is facing. So for example, if you take one desk and move it all the way to the back of the room, but keep it is still facing the front of the classroom, then that means that desk has correct orientation (because it is still facing the front of the classroom) and incorrect permutation (because it is in the wrong location). Similarly, if you take a desk and just flip it around to make it face the back of the classroom, then that means that desk has correct permutation (because it is still in the same location) and incorrect orientation (because it is not facing the front of the classroom). This same concept works the same with pieces on a Rubik’s cube. Below are pictures of pieces on a Rubik’s cube with correct permutation and incorrect orientation. It should be easy to see that each piece is in the correct location, but facing the wrong way.

 
Ok I think we’re now ready to get started.
NOTE: For this entire guide, make sure you are holding the cube with the white face on top and the red face in the front, otherwise this guide will not work. Every picture I show will show of two views. It will either show a view of the white face on the top, red in front, and blue on right, OR the yellow face on bottom, the red in front, and blue on right. This is all shown in the images below.  

 

 
Step 1 - Corner Orientation
The first step is getting all of the corners to face the correct way. This is the easiest step in solving a Rubik’s cube blindfolded and the steps get progressively more difficult as we move along. The first thing you need to learn to do is to recognize which corners are oriented correctly and which are oriented incorrectly. As it turns out, recognizing this isn’t too hard at all. There is only one rule, and that is: -          A corner is oriented correctly if it has a white or yellow sticker on the top face or bottom face, otherwise it is oriented incorrectly. Since a corner piece has three stickers on it, a corner has three possible orientations. Two of them are incorrect, and only one is correct. The way I...
