## Introduction: Rubik's Cube Tricks-center Piece.

How to solve a Rubik's Cube so that the only the center places are out of place. You must have already solved the Rubik's cube in order to continue.

## Step 1: Notation

Before you start, you will have understand some basic notation, or these steps will confuse you.

F = Front (the side that faces you)

B = Back(the side that faces away from you)

BT = Bottom(The side that faces down)

R = The right side

L = the left side

* = Inverted. This goes after a side abbreviation, and it means that you turn the specified side** counter-clockwise, as if it were facing you** .

This is very important, because if you reverse the direction for which you turn the side, it can mess you up.

Example: Ri = Right side, inverted (counter-clockwise)

D = Down (clockwise)

These notations make up *Algorithms * which sounds fancy and smart, but is actually quite simple. (You can impress your friends by saying that you used and algorithm to solve this.) An Algorithm is just a set of rules used in problem solving. To solve this, you will use four algorithms, each made up of two corresponding movements. As you will see, the algorithms use one inverted movement, and one standard movement of the opposing side. Algorithms in this project are grouped together using parenthesis (), much like coordinates on a graph.

For example, in the first algorithm, (Ri, L), You turn the right side counter-clockwise, and you turn the opposing side clockwise.

List of algorithms.

(Ri, L)

(Bi, F)

(Ui, D)

(Ri, L)

The first and last algorithms are the same, and you must repeat them as shown.

## Step 2: The First Algorithm

To begin, hold your FULLY SOLVED Rubik's cube so that the red side is facing you. It is important to remember which side you started on, because if you set the cube down and forget, it will not always be obvious which side you started with. If you remember which side you started with, but you don't know which side is which, just look at the center piece. whatever color the center piece is, that is the color of the side.

Note: You do not have to start on the red side, but for the sake of consistency and simplicity, we will use the blue side for this demonstration.

Hold the cube and complete the algorithm (Ri, L) - Right inverted, Left.

Your cube should look like this:

## Step 3: The Second Algorithm

For the next step, take the cube and complete the algorithm (Bi, F).

Your cube should look like this:

## Step 4: The Third Algorithm

Hold your cube and complete the algorithm (Ui, D).

Your cube should look like this:

## Step 5: The Final Algorithm

To complete the cube, complete the algorithm (Ri, L). You have already learned this.

Your cube should look like this:

## Step 6: Congratulations

Congratulations, you have just solved a Rubik's cube so that the outside pieces encircle the center piece that lies directly to the left of the center piece. If you want to undo this, simply follow these inverse algorithms:

(Li, R)

(Di, U)

(Fi, B)

(Li, R)

Now your cube is solved correctly, and you can go amaze your friends.

nice trick

I do not even understand any thing

Or you can just do M and E moves over and over (google it if you don't know what they are)

Nice tricks! Read these instructable for the Rubik's Cube solution + tips: https://www.instructables.com/id/How-to-solve-a-Rubiks-Cube-for-the-first-time/

Sorry for the bad picture quality. My camera wouldn't focus.

nice, although i already knew how to do this :)
