The world of speedcubing is a fascinating one, filled with complex algorithms, lightning-fast reflexes, and a constant quest for optimization. Two methods dominate the landscape: CFOP (Fridrich) and Roux. The central question debated among cubers is: which method is inherently faster? This article delves into a comprehensive comparison of CFOP and Roux, examining their strengths, weaknesses, learning curves, and the factors influencing a cuber’s potential speed with each.
Understanding the CFOP and Roux Methods
Before comparing their speeds, understanding the core mechanics of each method is essential.
The CFOP (Fridrich) Method: Layers First
CFOP, also known as the Fridrich method, is the most widely used speedcubing method. It follows a layers-first approach, solving the cube layer by layer. The method can be broken down into four main stages:
- Cross: Solving the cross on the first layer (usually the bottom).
- F2L (First Two Layers): Solving the first two layers simultaneously.
- OLL (Orient Last Layer): Orienting the last layer, making all pieces on the last layer have the correct color facing upwards.
- PLL (Permute Last Layer): Permuting the last layer, placing all the last layer pieces in their correct positions.
CFOP relies heavily on memorized algorithms (algos). Speedcubers learn hundreds of algorithms for OLL and PLL, allowing them to solve these steps quickly. The key to fast CFOP solves is recognizing patterns and executing the appropriate algorithm with speed and precision.
The Roux Method: Blocks and Edges
The Roux method, developed by Gilles Roux, takes a different approach. Instead of layers, Roux focuses on building blocks and orienting edges. Here’s a breakdown:
- First Block (FB): Solving a 1x2x3 block on the left side of the bottom layer.
- Second Block (SB): Solving a 1x2x3 block on the right side of the bottom layer, opposite the first block.
- CMLL (Corners of the Middle Layer): Orienting and permuting the corners of the middle layer.
- LSE (Last Six Edges): Orienting and permuting the last six edges.
Roux is often praised for its move economy, generally requiring fewer moves than CFOP for a typical solve. Roux relies more on intuition and less on memorized algorithms than CFOP, particularly in the FB and SB stages. LSE utilizes a combination of algorithms and intuitive solving.
CFOP vs. Roux: A Head-to-Head Comparison
The question of which method is faster isn’t straightforward. Both have advantages and disadvantages.
Algorithm Count and Memorization
CFOP requires memorizing a significantly larger number of algorithms than Roux. While beginners can start with a subset of OLL and PLL algorithms, achieving top speeds necessitates learning virtually all of them. This can be a daunting task, requiring considerable time and effort. Roux, on the other hand, utilizes fewer algorithms, particularly for CMLL and LSE, which can be solved intuitively to a significant degree. This lower algorithm count can make Roux more appealing to cubers who prefer a less memory-intensive approach.
Move Count and Efficiency
Roux is known for its efficiency in terms of move count. It often achieves lower move counts than CFOP, potentially leading to faster execution times. This efficiency stems from its block-building approach and its ability to solve the last six edges with a relatively small number of moves. While CFOP can achieve low move counts with advanced techniques like ZBLL (solving OLL and PLL simultaneously), these techniques require learning an even larger number of algorithms, further increasing the memorization burden.
Look-Ahead and Planning
Look-ahead, the ability to anticipate future steps while executing current ones, is crucial for speedcubing. CFOP’s layers-first approach can sometimes make look-ahead challenging, especially during F2L, where solving pairs can disrupt other pieces. Roux, with its block-building strategy, often allows for better look-ahead, as the solving process is more predictable. This improved look-ahead can translate to smoother solves and faster times.
Rotation Dependence
CFOP is highly rotation-dependent. The orientation of the cube significantly impacts the algorithms used and the efficiency of the solve. Cubers must constantly rotate the cube to execute algorithms from different angles. Roux, in contrast, is much less rotation-dependent. Most of the solve can be performed with the cube held in a fixed position, reducing the time spent on rotations and improving overall speed. This reduced rotation dependence is a significant advantage for Roux.
Learning Curve and Accessibility
CFOP has a steeper initial learning curve due to the need to memorize a large number of algorithms. However, many resources are available for learning CFOP, including tutorials, websites, and online communities. Roux has a more gradual learning curve, with the initial stages being relatively easy to grasp. However, mastering Roux and achieving top speeds requires a deep understanding of the method and the ability to solve LSE efficiently, which can be challenging.
Factors Influencing Speed: Beyond the Method
While the choice of method is important, several other factors significantly influence a cuber’s speed.
Practice and Muscle Memory
Regardless of the method chosen, consistent practice is essential for improving speed. Muscle memory, the ability to execute algorithms without consciously thinking about each move, is crucial for achieving fast times. Regular practice builds muscle memory and improves overall execution speed.
Turning Speed and Dexterity
A cuber’s turning speed is a critical factor in determining overall speed. Faster turning speed allows for quicker execution of algorithms and faster solves. Developing good finger tricks, efficient turning techniques, and using a high-quality speedcube are essential for maximizing turning speed.
Cube Quality and Setup
The quality of the speedcube used can significantly impact turning speed and overall performance. A smooth, fast cube allows for easier execution of algorithms and reduces the likelihood of lockups. Cube setup, which involves adjusting the tension and lubricating the cube, is also important for optimizing performance.
Mental Acuity and Focus
Maintaining focus and concentration during a solve is essential for avoiding mistakes and optimizing speed. Mental fatigue can negatively impact performance, so it’s important to take breaks and practice in a focused environment.
The Verdict: Which Method Reigns Supreme?
The “better” method ultimately depends on individual preferences and strengths. There is no definitive answer to the question of which method is faster.
Some cubers find CFOP more intuitive and enjoy the challenge of memorizing and executing a large number of algorithms. They may excel with CFOP due to their strong memorization skills and ability to develop fast turning speeds.
Other cubers prefer Roux’s move economy and reduced rotation dependence. They may excel with Roux due to their strong intuitive solving skills and ability to plan ahead.
Here’s a summary comparing the key differences:
| Feature | CFOP (Fridrich) | Roux |
|---|---|---|
| Approach | Layers First | Blocks and Edges |
| Algorithm Count | High (hundreds) | Lower (fewer) |
| Move Count | Generally higher | Generally lower |
| Look-Ahead | Can be challenging | Potentially better |
| Rotation Dependence | High | Low |
| Learning Curve | Steeper initially | More gradual |
The current world record single solve and average of 5 solves are held by cubers using CFOP, demonstrating its potential for achieving extremely fast times. However, many top cubers also use Roux and achieve impressive results. The key is to choose the method that best suits your individual strengths and preferences and to dedicate the time and effort required to master it. Ultimately, the fastest method is the one you enjoy the most and are most motivated to practice.
It’s worth noting that some cubers even choose to hybridize the methods, using parts of both CFOP and Roux in their solves. This approach can be effective for leveraging the strengths of each method and optimizing overall speed.
Ultimately, the “best” method is subjective. Experiment with both CFOP and Roux, consider your strengths and weaknesses, and choose the method that you find most enjoyable and rewarding.

What are the fundamental differences between the Roux and CFOP methods for speedcubing?
The CFOP method, often called the Fridrich method, is a layer-by-layer approach. It solves the cross first, then the first two layers (F2L), orients the last layer (OLL), and finally permutes the last layer (PLL). This method relies heavily on algorithm memorization, particularly for OLL and PLL, often requiring hundreds of algorithms to be competitive.
The Roux method, in contrast, focuses on block building. It begins by building a 1x2x3 block on the left side and another on the right side of the bottom layer. Then, it solves the remaining four corners of the first and second layers (CMLL) without disturbing the blocks. Finally, the last six edges and four corners (LSE) are solved using a combination of algorithms and intuitive moves, often minimizing rotations and emphasizing look-ahead.
Is the Roux method inherently faster than CFOP, or does it depend on the individual cuber?
There is no inherent speed advantage in either method. While anecdotal evidence and certain statistics might suggest a trend, the ultimate speed of a cuber depends significantly on their individual strengths, weaknesses, practice habits, and preferences. Some cubers excel at algorithm memorization, making CFOP faster for them, while others are better at intuitive block building and look-ahead, potentially leading to faster Roux solves.
The optimal method is subjective and dependent on the cuber’s aptitude and dedication to mastering it. Both methods have been used to achieve world-class solve times. The choice between Roux and CFOP should be based on which method aligns best with a cuber’s individual style and learning preferences, rather than an assumption of inherent speed superiority.
What are the key advantages of the Roux method for speedcubing?
One major advantage of the Roux method is its lower move count compared to CFOP. By focusing on block building and reducing rotations, Roux often leads to more efficient solutions with fewer individual moves. This lower move count can translate to faster solve times, especially for cubers who struggle with high TPS (turns per second) requirements.
Another advantage is its reliance on fewer algorithms than CFOP. While Roux does require learning a set of CMLL and LSE algorithms, the total number is significantly less than the hundreds needed for full OLL and PLL in CFOP. This makes Roux appealing to cubers who prefer a more intuitive and less algorithm-heavy approach, focusing more on look-ahead and move efficiency.
What are the main drawbacks or disadvantages of learning the Roux method?
One significant drawback of the Roux method is the initial learning curve. Building the first two blocks can be challenging for beginners accustomed to layer-by-layer methods. It requires spatial reasoning and an understanding of how moves affect the blocks, which can be difficult to grasp initially. This initial learning hump can deter some beginners.
Another disadvantage is the reliance on good look-ahead skills. While CFOP also benefits from look-ahead, Roux requires it even more to plan block building and LSE solutions efficiently. Without strong look-ahead, the lower move count advantage can be negated by pauses and inefficiencies during the solve. This can require more deliberate practice and focus on prediction.
How does look-ahead differ between Roux and CFOP, and why is it important?
In CFOP, look-ahead primarily focuses on planning the next F2L pair or anticipating the orientation and permutation of the last layer. Cubers are often looking for pieces that can be inserted easily or recognizing patterns to apply algorithms. The focus is largely on identifying and executing known sequences of moves.
Roux look-ahead is more holistic, involving predicting how moves will affect the existing blocks and planning the subsequent block building or LSE steps. It’s less about recognizing specific patterns and more about visualizing the overall state of the cube and anticipating the consequences of each move. This requires a deeper understanding of the cube’s mechanics and how different pieces interact.
What is CMLL in the Roux method, and how does it compare to OLL in CFOP?
CMLL stands for Corners of the Middle Layer Last Layer. It is the step in the Roux method where the four corners of the first and second layers are solved while maintaining the already built blocks. This step essentially solves the corners without disrupting the 1x2x3 blocks on the left and right sides. CMLL requires learning a set of algorithms, though significantly fewer than the number required for full OLL.
OLL, or Orient Last Layer, in CFOP, focuses on orienting all the pieces (edges and corners) of the last layer, making all the faces of the last layer the same color. It involves learning a large number of algorithms to handle various orientations of the last layer. While both CMLL and OLL are about solving or orienting pieces, CMLL solves only corners, while OLL solves both edges and corners, hence the greater algorithm count.
What are some effective practice techniques for improving speed in the Roux method?
One effective practice technique is to focus on developing strong block building skills. This involves practicing building the first two blocks quickly and efficiently, focusing on move count and minimizing rotations. Another useful drill is to practice CMLL algorithms until they become second nature, allowing for faster execution and recognition during solves.
Furthermore, dedicating time to improving look-ahead is crucial. This can be done by practicing slow solves, consciously focusing on predicting the effects of each move and planning the next steps. Regular solves with attention to look-ahead will gradually improve your ability to anticipate and react, leading to faster overall solve times in the Roux method.
