3×3 Rubik’s Cube Solver

The Rubik’s Cube is a classic puzzle game that has been challenging people for over 40 years. The 3×3 Rubik’s Cube is the original and most common version of the puzzle. Solving a Rubik’s Cube can be a daunting task, but with the right approach and practice, anyone can learn how to do it. In this step-by-step guide, we will break down the process of solving a 3×3 Rubik’s Cube into easy-to-follow steps. By the end of this guide, you will be able to solve a Rubik’s Cube on your own.

Step 1: Understanding the Cube

Before you start solving the Rubik’s Cube, it’s important to understand the different parts of the cube. The cube has six faces, each with a different color. The faces are labeled as follows:

• Up (U)
• Down (D)
• Left (L)
• Right (R)
• Front (F)
• Back (B)

The cube also has three layers, which are referred to as the top layer, middle layer, and bottom layer. The top layer is the layer that contains the up face, the middle layer is the layer between the top and bottom layers, and the bottom layer is the layer that contains the down face.

Step 2: Solving the Cross

The first step in solving the Rubik’s Cube is to solve the cross on the bottom layer. Start by choosing a color for the center of the cross. Then, look for edge pieces that have that color on one side. Place those pieces on the bottom layer so that the color on the side of the piece matches the center color. Continue this process until you have a cross on the bottom layer.

Step 3: Solving the Corners

Next, solve the corners of the bottom layer. Look for corner pieces that have two of the same colors on them. Place those pieces in the correct position so that the colors match the adjacent sides. Then, turn the bottom layer until the corner is in the correct orientation, and use the following algorithm to place it in the correct position:

R’ D’ R D

Repeat this process for each corner until all corners are solved.

Step 4: Solving the Middle Layer

Once the bottom layer is solved, it’s time to move on to the middle layer. Look for edge pieces on the top layer that have a color that matches one of the center colors on the middle layer. Then, position the edge piece so that it is directly above the spot where it needs to go on the middle layer. Use the following algorithm to move the piece into the correct position:

F U R U’ R’ F’

Repeat this process for each edge piece until the middle layer is solved.

Step 5: Solving the Top Layer

The final step in solving the Rubik’s Cube is to solve the top layer. There are four stages to this process:

Stage 1: Orienting the Edges

Look for edge pieces on the top layer that have two colors that match the adjacent sides. Then, use the following algorithm to move the piece into the correct orientation:

F R U R’ U’ F’

Repeat this process until all edge pieces are oriented correctly.

Stage 2: Positioning the Corners

Look for corner pieces on the top layer that have two colors that match the adjacent sides. Position the piece so that it is directly above the spot where it needs to go on the bottom layer. Then, use the following algorithm to move the piece into the correct position:

R’ D’ R D

Repeat this process for each corner until all corners are in the correct position.

Stage 3: Orienting the Corners

Look for corners on the top layer that are in the correct position but are oriented incorrectly. Place your left hand on the left side of the cube and your right hand on the back side. Then, use the following algorithm to move the corner into the correct orientation:

R’ D’ R D

Repeat this process for each corner until all corners are oriented correctly.

Stage 4: Finishing the Cube

At this point, the cube should be almost solved, but there may be some edge pieces that are in the wrong position. To fix this, hold the cube so that one of the misplaced edge pieces is in the front right position on the top layer. Then, use the following algorithm to swap that piece with the one in the back right position on the top layer:

R U R’ U’ R’ F R2 U’ R’ U’ R U R’ F’

Repeat this process until all edge pieces are in the correct position.

Congratulations, you have solved the Rubik’s Cube!
