Introduction
Asensio, have you ever found yourself staring at a Rubik’s Cube, feeling both fascinated and intimidated by this three-dimensional puzzle? Solving this notorious toy can be a daunting task, but fear not! In this article, we will guide you step-by-step through the process of solving a 3×3 Rubik’s Cube. By the end of this guide, you will be able to impress your friends and family with your newly acquired skills.
The History of Rubik’s Cube
The Rubik’s Cube was invented in 1974 by Hungarian sculptor and professor of architecture, Erno Rubik. Rubik wanted to create a toy that could help his students understand three-dimensional problems, and thus, the Rubik’s Cube was born. Little did he know that his invention would become a global sensation, with over 350 million cubes sold worldwide as of 2021.
The Anatomy of Rubik’s Cube
Before we dive into the solving process, let’s take a moment to examine the anatomy of a Rubik’s Cube. A standard 3×3 Rubik’s Cube has six faces, each consisting of nine smaller cubes called cubies. The faces can be twisted and turned, and the goal is to align all the colors on each face, creating a uniform color for each side of the cube.
The Notation System
Before we begin, we need to introduce a notation system that will help us describe the movements of the Rubik’s Cube. We will be using letters to indicate which face we are turning and in what direction. The six faces of the cube are labeled with the letters F, B, U, D, L, and R, standing for front, back, up, down, left, and right, respectively. We will use an apostrophe (‘) to indicate a counterclockwise turn of a face, and we will use the number 2 to indicate a 180-degree turn of a face. For example, to indicate a clockwise turn of the front face, we will use the letter F, and to indicate a counterclockwise turn of the back face, we will use the letter B with an apostrophe (B’).
The Basic Method
Before we get into specific algorithms, we will introduce the basic method for solving a 3×3 Rubik’s Cube. This method involves solving the cube layer by layer. We will start by solving the bottom layer, then the middle layer, and finally the top layer.
Solving the Bottom Layer
The first step in solving the bottom layer is to pick a color to start with. We recommend starting with white, as it is the most visible color and will generally make the solving process easier. The goal is to create a cross on the bottom layer with this color. To do this, we will first need to locate the white center cubie and position it on the bottom layer. We can then look for edge cubies with white on them and move them into place using a few simple algorithms.
Solving the Middle Layer
Once we have solved the bottom layer, we can move on to the middle layer. The goal of this step is to create a complete second layer on the cube. To do this, we will need to locate edge cubies with the correct colors and position them correctly using a set of algorithms.
Solving the Top Layer
The final step in solving the Rubik’s Cube is to solve the top layer. This is often the most challenging step, as it involves creating a uniform color on the top face while ensuring that the rest of the cube remains solved. There are a few different methods for solving the top layer, but we will be using the beginner’s method, which involves solving one corner at a time and then orienting the edges.
How to Solve a 3×3 Rubik’s Cube
Step 1: Solve the Bottom Layer Cross
The first step in solving a 3×3 Rubik’s Cube is to solve the bottom layer cross. Start by picking a color to start with, and find the center cubie that matches that color. Once you have located the center cubie, position it on the bottom layer. Look for edge cubies with the same color as the center cubie, and position them so that they form a cross on the bottom layer with the center cubie in the center of the cross.
Step 2: Solve the Bottom Layer Corners
Once you have created the bottom layer cross, it’s time to solve the corners of the bottom layer. Look for corner cubies with the same color as the center cubie and position them so that they match the color of the adjacent center cubies.
Step 3: Solve the Middle Layer
Now that the bottom layer is solved, it’s time to move on to the middle layer. The goal of this step is to create a complete second layer on the cube. Start by finding an edge cubie that has a color that matches the center cubie on the top face. Move the edge cubie so that it lines up with the corresponding center cubie on the side face, and use the following algorithm to insert it into the middle layer: F U R U’ R’ F’.
Step 4: Orient the Top Layer Corners
The next step is to orient the corners of the top layer. Look for a corner cubie that is not in the correct position, and hold the cube so that the corner cubie is in the front top right position. Use the following algorithm to move the corner cubie into the correct position while preserving the orientation of the other corners: R’ D’ R D.
Step 5: Position the Top Layer Corners
Now that the corners of the top layer are oriented correctly, it’s time to position them in the correct location. Hold the cube so that the unsolved corner is in the front top right position. Use the following algorithm to move the unsolved corner to the top left position: U R U’ L’ U R’ U’ L.
Step 6: Orient the Top Layer Edges
The next step is to orient the edges of the top layer. Look for an edge cubie that is not in the correct position or orientation, and hold the cube so that the edge cubie is in the front top position. Use the following algorithm to move the edge cubie into the correct position while preserving the orientation of the other edges: F U R U’ R’ F’.
Step 7: Position the Top Layer Edges
Now that the edges of the top layer are oriented correctly, it’s time to position them in the correct location. Turn the U face until you find an unsolved edge on the top layer, and position it so that it lines up with the corresponding center cubie on the side face. Use the following algorithm to insert the edge cubie into the top layer: R U R’ U R U2 R’.
