How to Solve a Rubik's Cube: A Beginner's Guide
Have you ever wondered how to solve a Rubik's cube? The Rubik's cube is one of the most popular and challenging puzzles in the world. It consists of a 3x3x3 cube with six faces, each divided into nine smaller squares of one of six colors: white, yellow, red, blue, green, and orange. The goal is to twist and turn the cube until each face has only one color.

Solving a Rubik's cube may seem impossible at first, but it is actually not as hard as it looks. With some practice and patience, anyone can learn how to solve it in a few minutes. Solving a Rubik's cube can also improve your memory, concentration, logic, and spatial awareness skills.
In this article, we will show you how to solve a Rubik's cube using a simple and easy method that anyone can follow. This method involves solving the cube layer by layer, starting from the white face and ending with the yellow face. You will only need to learn a few algorithms, which are sequences of moves that rotate certain pieces on the cube. Don't worry, we will explain everything step by step with pictures and examples.
Before we start, let's go over some basic terms and notations that you will need to know when solving a Rubik's cube.
Introduction
Face: A face is one of the six sides of the cube. Each face has a center piece, which is fixed and determines the color of that face. For example, the white face has a white center piece.
Edge: An edge is a piece that has two colors and is located between two center pieces. For example, a white-red edge is an edge that has white and red stickers on it.
Corner: A corner is a piece that has three colors and is located at the intersection of three faces. For example, a white-red-blue corner is a corner that has white, red, and blue stickers on it.
Cubie: A cubie is a generic term for any piece on the cube, either an edge or a corner.
Layer:. A layer is a group of nine cubies that form one face of the cube and the adjacent edges and corners. For example, the top layer consists of the white center, the four white edges, and the four white corners.
Notation: A notation is a letter or a symbol that represents a move on the cube. There are six basic moves that correspond to the six faces of the cube: F (front), B (back), U (up), D (down), L (left), and R (right). Each letter means to turn that face clockwise by 90 degrees. To turn a face counterclockwise, add an apostrophe (') after the letter. For example, F' means to turn the front face counterclockwise. To turn a face twice, add a 2 after the letter. For example, U2 means to turn the up face twice.
Algorithm: An algorithm is a sequence of moves that accomplishes a specific goal on the cube. For example, R U R' U' is an algorithm that swaps two edge pieces on the top layer. Algorithms are usually written in brackets and followed by their names or descriptions.
Now that you know the basics, let's start solving the cube!
Step 1: Solve the White Cross
The first step is to make a white cross on the top face of the cube. This means that you need to match the four white edge pieces with the four center colors on the sides of the cube. For example, the white-red edge piece should be next to the red center piece, and so on.
To do this, you need to find the white edge pieces on the bottom layer and move them to the top layer using simple moves. You can use any face as your front face, as long as you keep it consistent throughout this step.
Here are some tips to help you solve the white cross:
Don't worry about the corners or the orientation of the edges at this point. You only need to match the colors of the edges and the centers.
If an edge piece is already on the top layer but not in its correct position, you can move it to the bottom layer by doing F2, R2, B2, or L2, depending on which side it is on.
If an edge piece is on the bottom layer but facing down, you can flip it up by doing F D F' or R D R', depending on which side it is on.
If an edge piece is on the bottom layer and facing up, you can bring it to the top layer by doing F' or R', depending on which side it is closer to.
Once you have an edge piece on the top layer and facing up, you can align it with its center color by doing U, U', or U2, depending on how far it is from its correct position.
After you align an edge piece with its center color, you can lock it in place by doing F2 or R2, depending on which side it is on.
Repeat these steps for all four edge pieces until you have a white cross on the top face.
To check if you have solved the white cross correctly, look at the top face and the four side faces of the cube. You should see a white cross on the top face and four matching colors on the side faces. If not, you may have placed some edge pieces in wrong positions or orientations. In that case, you need to fix them by moving them back to the bottom layer and then bringing them up again in their correct places.
Example
Let's look at an example of how to solve the white cross. Suppose your cube looks like this:
We can see that none of the white edge pieces are in their correct positions or orientations. Let's start with the white-red edge piece, which is on the bottom layer and facing down. We can flip it up by doing F D F', like this:
Now we have the white-red edge piece on the top layer and facing up. We can align it with the red center by doing U', like this:
Finally, we can lock it in place by doing F2, like this:
We have solved one edge piece of the white cross. We can repeat the same steps for the other three edge pieces until we have a complete white cross on the top face.
Step 2: Solve the White Corners
The next step is to solve the four white corner pieces on the top layer. This means that you need to match the three colors of each corner piece with the three center colors on the adjacent faces. For example, the white-red-blue corner piece should be next to the white, red, and blue center pieces, and so on.
To do this, you need to find the white corner pieces on the bottom layer and move them to the top layer using some simple algorithms. You can use any face as your front face, as long as you keep it consistent throughout this step.
Here are some tips to help you solve the white corners:
Don't worry about the edges or the orientation of the corners at this point. You only need to match the colors of the corners and the centers.
If a corner piece is already on the top layer but not in its correct position or orientation, you can move it to the bottom layer by doing R' D' R D or L D L' D', depending on which side it is on.
If a corner piece is on the bottom layer and has a white sticker facing down, you can bring it to the top layer by doing R' D' R or L D L', depending on which side it is closer to.
If a corner piece is on the bottom layer and has a white sticker facing front or right, you can bring it to the top layer by doing F D F' or R D R', depending on which side it is on.
If a corner piece is on the bottom layer and has a white sticker facing left or back, you can bring it to the top layer by doing B' D B or L' D L, depending on which side it is on.
Once you have a corner piece on the top layer and facing up, you can place it in its correct position by doing U, U', or U2, depending on how far it is from its correct position.
After you place a corner piece in its correct position, you can orient it correctly by doing one of these three algorithms: (R U R' U') (R U R' U') R U2 R', (R U2 R' U') (R U2 R'), or (R U R' U) (R U R' U) (R U R'). These algorithms will rotate the corner piece clockwise, counterclockwise, or twice, respectively. You can tell which algorithm to use by looking at the color of the front sticker of the corner piece. If it matches the front center color, use the first algorithm. If it matches the right center color, use the second algorithm. If it matches the left center color, use the third algorithm.
Repeat these steps for all four corner pieces until you have a complete white face on the top layer.
To check if you have solved the white corners correctly, look at the top face and the four side faces of the cube. You should see a white face on the top face and four matching colors on the side faces. If not, you may have placed some corner pieces in wrong positions or orientations. In that case, you need to fix them by moving them back to the bottom layer and then bringing them up again in their correct places.
Example
Let's look at an example of how to solve the white corners. Suppose your cube looks like this:
We can see that none of the white corner pieces are in their correct positions or orientations. Let's start with the white-red-blue corner piece, which is on the bottom layer and has a white sticker facing front. We can bring it to the top layer by doing F D F', like this:
Now we have the white-red-blue corner piece on the top layer and facing up. We can place it in its correct position by doing U2, like th
