The Rubik’s Cube is a 3D combination puzzle that has been a popular toy since it was invented in 1974 by Hungarian sculptor and professor of architecture Erno Rubik. The original Rubik’s Cube has six faces, each with nine colored squares, and the goal is to twist and turn the cube until each face is a single color. The puzzle has been popular for decades because of its challenging nature and the satisfaction of solving it. Keep reading if you’re ready to learn how to solve a Rubik’s Cube!

Understanding Rubik’s Cube notation and terminology

Before we dive into solving the Rubik’s Cube, it’s important to understand the notation and terminology used when discussing the puzzle. The Rubik’s Cube comprises six faces, and each face can be rotated in one of two directions: clockwise or counterclockwise. The notation describing these rotations is based on the letters representing each face.

The six faces of the Rubik’s Cube are labeled with the letters U (up), D (down), L (left), R (right), F (front), and B (back). A clockwise turn of the U face is denoted as U, while a counterclockwise turn is denoted as U’. A 90-degree turn of the U face is denoted as U2. This notation is used throughout the solving process, so becoming familiar with it is important.

The basic principles of solving a Rubik’s Cube

Before we jump into the 20-move algorithm for solving a Rubik’s Cube, it’s important to understand the basic principles of solving the puzzle. The first step in solving a Rubik’s Cube is to solve the first layer, or the “cross” on the top face. This involves matching the center square on each edge with the square of the face it belongs to.

Once the first layer is solved, the next step is to solve the second layer, or the “corners” on the top face. This involves matching up the corners of the top face with the corresponding colors on the adjacent edges.

Finally, the last step in solving a Rubik’s Cube is to solve the third layer or the “top” layer. This involves aligning the corners of the top layer with their corresponding edges and then aligning the edges until each face is a single color.

The 20-move algorithm for solving a 3x3 Rubik's Cube

Mathematician and computer scientist Tomas Rokicki discovered the 20-move algorithm for solving a 3×3 Rubik’s Cube in 2010. This algorithm involves a series of 20 moves that, when executed correctly, will solve the Rubik’s Cube every time.

The algorithm begins by solving the first two layers of the cube using a combination of basic principles and intuitive moves. Once the first two layers are solved, the algorithm completes the third layer in 20 moves. While the 20-move algorithm is not the fastest or most efficient method for solving a Rubik’s Cube, it is a great starting point for beginners and can be a foundation for learning more advanced algorithms.

Tips for mastering the 20-move algorithm

While the 20-move algorithm is a great starting point for beginners, it’s important to remember that it’s not the only way to solve a Rubik’s Cube. If you’re interested in mastering the 20-move algorithm, here are a few tips to keep in mind:

Practice, practice, practice! The more you solve the Rubik’s Cube using the 20-move algorithm, the more familiar you will become with the moves, and the faster you can solve the puzzle.
Break the algorithm down into smaller sections. Rather than trying to memorize all 20 moves at once, break the algorithm into smaller sections and practice each until you have it memorized.
Watch tutorials and read guides. Many online tutorials and guides can help you master the 20-move algorithm and other Rubik’s Cube algorithms.

Common mistakes to avoid when solving a Rubik’s Cube

When learning to solve a Rubik’s Cube, beginners tend to make a few common mistakes. Here are a few mistakes to avoid

Trying to solve the puzzle slowly. While practicing and working on your speed is important, trying to solve the puzzle too quickly can lead to mistakes and frustration.
Getting stuck on one step. If you are stuck on one step of the solving process, try taking a break and returning to it later. Sometimes a fresh perspective can help you see the solution more clearly.
Not using the correct notation. Correct notation is essential when solving a Rubik’s Cube, so understand the notation and terminology before you begin.

Advanced Rubik’s Cube algorithms for faster solving times

Plenty of advanced algorithms can help you solve the puzzle even faster if you want to take your Rubik’s Cube skills to the next level. Some popular advanced algorithms include the Fridrich method, the ZZ method, and the Roux method.
