Cracking the Cube: A Comprehensive Guide to Solving the Rubik’s Cube

The Rubik’s Cube, a seemingly complex puzzle of colorful squares, has captivated minds for decades. While it may appear daunting at first glance, the truth is that anyone can learn to solve it with the right guidance and a bit of practice. This comprehensive guide will break down the solution process into manageable steps, equipping you with the knowledge and techniques to conquer the cube.

Understanding the Cube: Basic Terminology

Before diving into the solution, it’s crucial to understand the cube’s anatomy and the language used to describe its movements. The Rubik’s Cube consists of:

• Center Pieces: These pieces are located at the center of each face and define the color of that face. They never move relative to each other.
• Edge Pieces: These pieces have two colors and are located between the corner pieces.
• Corner Pieces: These pieces have three colors and are located at the corners of the cube.

We use a notation system to represent the different turns you can make on the cube. Each letter represents a face, and the letter itself means to turn that face 90 degrees clockwise. An apostrophe (‘) after the letter means to turn the face 90 degrees counterclockwise. A “2” after the letter means to turn the face 180 degrees.

• F (Front): The face facing you.
• B (Back): The face opposite the front.
• R (Right): The face to your right.
• L (Left): The face to your left.
• U (Up): The top face.
• D (Down): The bottom face.

So, for example:

• R means turn the right face 90 degrees clockwise.
• L’ means turn the left face 90 degrees counterclockwise.
• U2 means turn the top face 180 degrees.

We’ll also use lowercase letters to indicate turning two layers at once. For example ‘r’ means turning the right layer and the adjacent middle layer at the same time, and ‘l’ means turning the left layer and the adjacent middle layer at the same time.

The Beginner’s Method: Layer by Layer

This guide will focus on the beginner’s method, also known as the layer-by-layer method. This method involves solving the cube one layer at a time, making it easy to understand and remember the steps.

Step 1: The White Cross

Our first goal is to create a white cross on the top face (assuming white is your chosen color). This means getting all four white edge pieces aligned with their corresponding center pieces on the side faces. Don’t worry about the corner pieces yet.

1. Find a white edge piece: Locate an edge piece that has white on one side.
2. Position the edge piece: Move the cube so that the white edge piece is on the bottom layer (the D layer).
3. Align the side color: Rotate the bottom layer (D layer) until the non-white color of the edge piece matches the color of the center piece on that face. For example, if the edge piece is white and blue, rotate the bottom layer until the blue side of the edge piece is aligned with the blue center piece.
4. Bring the edge piece to the top: Depending on the orientation of the edge piece, you’ll need to use one of the following sequences:
   • If the white side is facing down: F2
   • If the white side is facing towards you (on the front face): F R U R’
   • If the white side is on the right face: R U F’ U’
   • If the white side is on the back face: B’ L’ U’ L
   • If the white side is on the left face: L’ U’ B
5. Repeat: Repeat steps 1-4 for the remaining three white edge pieces.

By the end of this step, you should have a white cross on the top face, with each edge piece aligned with its corresponding center piece.

Step 2: The White Corners

Now, we need to solve the white corners, completing the entire first layer.

1. Find a white corner piece: Locate a corner piece that has white on one of its sides.
2. Position the corner piece: Move the cube so that the white corner piece is on the bottom layer (D layer), directly below the position where it needs to go in the top layer. The colors on the corner piece must correspond to the colors on the faces surrounding that corner in the top layer. For instance, if the corner piece has white, green, and orange, it must be positioned under the corner formed by the green and orange faces.
3. Orient the corner piece: Depending on the orientation of the white corner piece on the bottom layer, use one of the following algorithms:
   • White facing down: R U R’ U’ (Repeat until the white side is on top)
   • White facing the front face: U’ F’ U F
   • White facing the right face: R U R’
4. Repeat: Repeat steps 1-3 for the remaining three white corner pieces.

After this step, the entire first layer (the white face) should be solved.

Step 3: The Second Layer

Next, we’ll solve the middle layer. This involves placing the correct edge pieces into their correct positions without disturbing the solved first layer.

1. Find a middle layer edge piece: Locate an edge piece on the top layer that does not contain the color yellow (or whatever color is on your bottom face). These are the edge pieces that belong in the middle layer.
2. Determine the destination: Identify the two colors on the edge piece. These colors correspond to the center pieces on the adjacent faces where the edge piece needs to be placed.
3. Position the edge piece: Rotate the top layer (U layer) until the front color of the edge piece matches the color of the center piece on the front face.
4. Choose the correct algorithm: Determine if the edge piece needs to move to the left or to the right to reach its correct position. Use the corresponding algorithm:
   • Move to the Left: U’ L’ U L U F U’ F’
   • Move to the Right: U R U’ R’ U’ F’ U F
5. Edge piece in the wrong spot: If an edge piece is already in the middle layer but in the wrong position or orientation, use either of the above algorithms to replace it with an incorrect edge piece from the top layer. This will effectively move the incorrectly placed edge piece to the top layer, allowing you to position it correctly in the subsequent steps.
6. Repeat: Repeat steps 1-5 for the remaining middle layer edge pieces.

After completing this step, the first two layers of the cube should be solved.

Step 4: The Yellow Cross

Now we move to the last layer. Our goal here is to create a yellow cross on the bottom face (assuming yellow is the color opposite white). We don’t need to worry about the correct orientation of the yellow edge pieces yet, just that they form a cross.

There are four possible cases:

• Case 1: The Dot: Only the yellow center piece is visible on the bottom face.
• Case 2: The Line: A horizontal line of yellow edge pieces is visible on the bottom face.
• Case 3: The L-Shape: An L-shape of yellow edge pieces is visible on the bottom face.
• Case 4: The Cross: A yellow cross is already formed. If you have this, skip to the next step.

Regardless of which case you have, apply the following algorithm:

F R U R’ U’ F’

You may need to apply this algorithm multiple times to reach the yellow cross. If you start with the dot, you’ll get the L-shape, then the line, and finally the cross. Make sure the L-shape is in the top-left corner before applying the algorithm, and that the line is horizontal before applying the algorithm.

Step 5: Orient the Yellow Edges

In this step, we’ll orient the yellow edge pieces so that the colors on their sides match the colors of the center pieces on the corresponding faces. We want to get all the edge pieces aligned so we have a solved yellow cross.

1. Find correctly oriented edges: Look at the four yellow edge pieces. Count how many of them have their non-yellow color aligned with the center color on the side face. You are looking for at least one or two adjacent edges that are correctly oriented.
2. Orient adjacent correct edges: If you find two adjacent edge pieces that are correctly oriented, hold the cube so those two pieces are on the back and right faces. Then, perform the following algorithm:
   
   R U R’ U R U2 R’ U
3. Orient opposite correct edges: If you find two opposite edge pieces that are correctly oriented, hold the cube so those two pieces are on the front and back faces. Then, perform the following algorithm:
   
   R U R’ U R U2 R’ U2
4. No correct edges: If none of the edges are correctly oriented, perform the first algorithm (R U R’ U R U2 R’ U) from any angle. This will usually create a situation where you have two adjacent correct edges. Then, follow step 2.

After this step, all four yellow edge pieces should be correctly oriented, forming a solved yellow cross.

Step 6: Position the Yellow Corners

Now we need to position the yellow corner pieces correctly, meaning each corner piece needs to be under the three colors it ultimately belongs between, although the corner piece may not be oriented correctly yet.

1. Find a correctly positioned corner: Look for a corner piece on the bottom layer that has the three colors corresponding to the three faces it should be between. It doesn’t matter if the colors are oriented correctly on the corner piece itself; just that the piece is in the correct location.
2. Position the cube: If you find a correctly positioned corner piece, hold the cube so that corner piece is in the top-right-back corner. If you don’t find a correctly positioned corner piece, perform the algorithm below from any angle, then re-evaluate.
3. Apply the algorithm: Perform the following algorithm:
   
   U R U’ L’ U R’ U’ L
4. Repeat if necessary: Repeat steps 1-3 until all four corner pieces are in their correct positions. You may need to perform the algorithm multiple times.

Step 7: Orient the Yellow Corners

This is the final step! Now we need to orient the yellow corner pieces to complete the solve. This involves rotating the corner pieces in place until the yellow side is facing down.

1. Position the cube: Hold the cube so the unsolved yellow face is at the bottom.
2. Focus on one corner: Choose one corner piece on the bottom layer that is not correctly oriented. Keep this piece in the front-right-bottom corner (DRF).
3. Apply the algorithm: Perform the following algorithm until the yellow side of the corner piece is facing down:
   
   R’ D’ R D
4. Rotate the bottom layer: Rotate the bottom layer (D) so that the next unsolved corner piece is in the front-right-bottom (DRF) position.
5. Repeat the algorithm: Repeat step 3 for this new corner piece.
6. Repeat for all corners: Repeat steps 4 and 5 until all four corner pieces are correctly oriented (yellow side facing down).
7. Final move: Once all the corner pieces are oriented, you will likely find the top layer is scrambled. Perform a U move or U’ move until the top layer is solved and the cube is complete.
