Step-by-Step Guide
Introduction to Solving a 2×2 Cube
Before we begin, it is crucial to understand some basic notation and terminology. The notation we will be using is as follows:
– U: turn the upper face 90 degrees clockwise
– L: turn the left face (when looking at the front) 90 degrees clockwise
– F: turn the front face 90 degrees clockwise
– R: turn the right face 90 degrees clockwise
– B: turn the back face 90 degrees clockwise
– D: turn the down face 90 degrees clockwise
The cube has six faces, and each face can be turned in one of three ways, resulting in 18 different possible moves.
Detailed, Step-by-Step Guide for Solving a 2×2 Cube
Now that we are familiar with the notation, let us move on to the step-by-step guide for solving the 2×2 cube.
Step 1: Solving the First Layer
– Start by selecting a color to solve first.
– Find the center piece of the chosen color and turn the cube so that this center piece is facing up.
– Next, find the four edge pieces that surround the center and position them correctly. Each edge piece should have the center piece’s color on one side and another color on the other side.
– If an edge piece is in the correct position, leave it be and move on to the next. If it is not in the correct position, hold the cube so that the edge piece is in the front left corner of the top layer and perform the following algorithm: L U L’ U’.
– Repeat this step until all four edge pieces are in the correct position.
Step 2: Solving the Second Layer
– Once the first layer is complete, the cube will look like an “L” shape.
– Holding the cube with the completed layer on the bottom and the unsolved layer on top, find an edge piece that needs to be solved.
– Position the unsolved edge piece directly above where it needs to go in the second layer.
– Perform the following algorithm: F U R U’ R’ F’.
– Repeat this step for the remaining three unsolved edge pieces in the second layer.
Step 3: Solving the Third Layer
– At this stage, the cube will have only the corner pieces left to solve.
– Hold the cube so that the completed layers are on the bottom and left side, and the unsolved layer is on the top.
– Position a corner piece directly above where it needs to go in the third layer (i.e., matching the two adjacent colors).
– Perform the following algorithm: U R U’ L’ U R’ U’ L.
– Repeat this step for the remaining three unsolved corner pieces.

Algorithm-Based Solution
In addition to the step-by-step guide, there are several algorithms that you can use to solve the 2×2 Rubik’s Cube. These algorithms consist of a series of moves designed to move specific pieces without disrupting others. It is essential to learn these algorithms to solve the cube efficiently and quickly.
There are many algorithms used to solve a 2×2 cube, such as CLL (Commute Last Layer), EG (Expert’s Method), and Ortega. Each method has its advantages and disadvantages, and the one you choose should be based on your preferences and skill level.
CLL (Commute Last Layer)
This method is a popular solution for solving 2×2 cubes. It is fast and easy to learn, making it perfect for beginners.
The CLL method is made up of two steps.
Step 1: Solve the top layer (like in our step-by-step guide)
Step 2: ‘Commute’ one of the corners to its final position while still preserving the orientation of the other two solved corners.
EG (Expert’s Method)
This method is a bit more complicated than the CLL method but can be faster for more experienced cubers. As its name suggests, it is more complex and faster than other methods.
The EG method is made up of two steps.
Step 1: Bring all corner pieces to their designated slots.
Step 2: Permute the edge pieces to place them into their designated slots.
Ortega
The Ortega method is another popular solution for solving the 2×2 Rubik’s Cubes. It is named after its creator, Victor Ortega. This method is slightly more complex than the CLL method, but it is still easier to learn than the EG method.
The Ortega method is made up of two steps.
Step 1: Solve the first layer as already explained.
Step 2: Solve all five remaining pieces using a combination of moves.
Comparison of Methods
There are a variety of methods for solving a 2×2 cube. But how do they compare to one another? We will discuss the criteria for comparison below.
Speed
One of the most critical factors to consider is speed. For speedcubers who are in a competition, the faster solution can mean the difference between winning and losing.
Effectiveness
The effectiveness of a method is another crucial factor to consider. Some methods may be faster, but they may require more memorization, making them harder to remember.
Difficulty
Another essential factor to consider is the difficulty of the method. Some methods may be more challenging to learn, while others may be easier but not as fast.
Common Mistakes to Avoid
When it comes to solving the 2×2 cube, there are common mistakes that beginners make. Here are some of the most common mistakes and tips on how to avoid them.
Not Knowing the Notation
Not knowing the notation can make it challenging to follow the step-by-step guide or solve the cube using algorithms. Take the time to learn and practice the notation.
Not Solving the Cube Layer by Layer
Trying to solve the cube without solving it layer by layer can make it more challenging to solve, and it can take longer. Stick to solving the 2×2 cube layer by layer
Forgetting to Rotate the Cube
It can be easy to get lost in a sequence of moves and forget to rotate the cube. Remember to rotate the cube as needed throughout the different steps.
Practice Exercises
Practicing is an essential element in mastering the art of solving the 2×2 cube. Here are some exercises to help you practice your 2×2-solving skills.
Repeat the Steps
Practice repeating each step until you can do it without looking at your notes or the guide.
Practice with Different Starting Positions
Start with the different positions of the 2×2 cube and try solving it from every position.
Timing Your Solves
Use a timer to keep track of your solves. This can give you an idea of how long it takes you to solve a 2×2 cube and can help you track improvements.
