Solve A Rubik’s Cube

Learning how to solve a Rubik’s cube is a rewarding challenge that transforms a confusing mess of colors into a structured, logical sequence. For decades, this 3×3 puzzle has fascinated millions, often appearing impossible to those who haven’t yet learned the underlying mechanics. By breaking the process down into manageable layers, anyone can master the skills necessary to complete the cube.

The secret to success lies in understanding that you are moving pieces, not just stickers. Each piece has a specific place where it belongs based on its colors. Once you grasp the basics of notation and layer-by-layer strategy, you will find that the path to a solved cube is well within your reach.

Understanding the Cube Anatomy

Before you begin to solve a Rubik’s cube, you must understand the different types of pieces that make up the puzzle. The cube consists of three distinct parts that never change their function or relationship to one another.

  • Center Pieces: These have only one color and are fixed in the middle of each face. They define the color of that side when the cube is solved.
  • Edge Pieces: These have two colors and sit between the corners. There are 12 edge pieces in total.
  • Corner Pieces: These have three colors and are located at the vertices of the cube. There are 8 corner pieces in total.

It is important to remember that the center pieces do not move relative to each other. For example, the white center is always opposite the yellow center, and the blue center is always opposite the green center.

Mastering Cube Notation

To follow the instructions for how to solve a Rubik’s cube, you need to learn the standard notation used for algorithms. Each letter represents a 90-degree clockwise turn of a specific face.

  • R (Right): Turn the right face clockwise.
  • L (Left): Turn the left face clockwise.
  • U (Up): Turn the top face clockwise.
  • D (Down): Turn the bottom face clockwise.
  • F (Front): Turn the front face clockwise.
  • B (Back): Turn the back face clockwise.

If a letter is followed by an apostrophe (e.g., R’), it means you should turn that face 90 degrees counter-clockwise. A letter followed by the number 2 (e.g., U2) means you should turn that face 180 degrees.

Step 1: Creating the White Cross

The first practical step in how to solve a Rubik’s cube is to form a white cross around the white center piece. While this step is often done intuitively, the goal is to align the white edge pieces with both the white center and their respective side centers.

Start by finding a white edge piece. Move it so that the white side of the edge is adjacent to the white center, and the other color on the edge matches the side center piece. Repeat this for all four white edges until a cross is formed on the top face.

Step 2: Solving the White Corners

Once the cross is complete, you must place the four white corner pieces to finish the first layer. Find a corner piece on the bottom layer that contains white. Rotate the bottom layer until that corner is directly below the spot where it needs to go.

Use the algorithm R’ D’ R D repeatedly until the corner piece is correctly oriented in the top layer. Once all four corners are in place, the entire top layer should be white, and the top row of the side faces should match their center colors.

Step 3: Solving the Middle Layer

To solve the middle layer, you need to place four edge pieces into their correct positions. Flip the cube over so the white face is now on the bottom. Look for an edge piece on the top layer that does not have any yellow on it.

Align the front color of the edge piece with its matching center. If the piece needs to move to the right, use this algorithm: U R U’ R’ U’ F’ U F. If the piece needs to move to the left, use: U’ L’ U L U F U’ F’. Continue this until all middle layer edges are placed.

Step 4: Forming the Yellow Cross

Now that the first two layers are complete, focus on the top (yellow) face. Your goal here is to create a yellow cross. You may see just the yellow center, an ‘L’ shape, a horizontal line, or the cross itself.

Regardless of the pattern (except the cross), use the algorithm F R U R’ U’ F’. If you have the ‘L’ shape, hold it so the pieces are at the back and left. If you have a line, hold it horizontally. Repeat the algorithm until the yellow cross is formed.

Step 5: Aligning the Yellow Edges

Even if you have a yellow cross, the side colors of the yellow edges might not match the side centers. Rotate the top layer to see how many edges match. If two adjacent edges match, hold them at the back and right positions.

Perform the algorithm R U R’ U R U2 R’. This sequence swaps the remaining edges into their correct positions. After one or two turns of the top layer, all yellow edges should now match the side centers.

Step 6: Positioning the Yellow Corners

In this step of how to solve a Rubik’s cube, you aren’t worried about the orientation of the corners, just their location. Find one corner that is already in the right spot (even if the colors are twisted).

Hold the cube so the correct corner is in the front-right-top position and perform: U R U’ L’ U R’ U’ L. If no corners were correct, perform the algorithm once to get one in place, then repeat as needed until all corners are in their correct locations.

Step 7: Final Orientation

This is the final stage. Your corners are in the right spots, but they need to be rotated. Hold the cube with a yellow corner that needs twisting in the front-right-top position. Perform R’ D’ R D until that corner is oriented correctly with yellow facing up.

Crucial: Once one corner is fixed, do not move the whole cube. Only rotate the top layer (U) to bring the next unsolved corner to the front-right-top position. Repeat R’ D’ R D until the entire cube is solved. It will look messy during the process, but it will resolve itself on the final turn.
