Speedcubing, the art and sport of solving a Rubik’s Cube as quickly as possible, has captivated minds for decades. While the most popular method is CFOP (Fridrich), a lesser-known but equally fascinating approach is the Roux method. This method, favored by many for its intuitive moves and reduced reliance on algorithms, boasts impressive solve times. So, what exactly constitutes the “fastest” Roux solve, and what factors contribute to achieving these remarkable speeds?
Understanding the Roux Method
The Roux method, created by French speedcuber Gilles Roux, is a block-building method that emphasizes intuitive moves and minimal rotations. Unlike CFOP, which focuses on solving layers, Roux focuses on building blocks of pieces and orienting them into their final positions. This approach often results in fewer move counts and a more fluid solving experience.
The Core Principles of Roux
At its heart, the Roux method breaks down the cube solving process into several key stages. These stages, executed sequentially, build upon each other to eventually complete the puzzle. Understanding these stages is crucial to comprehending how speedcubers optimize their solves.
First Block (FB)
The first stage involves building a 1x2x3 block on the left side of the cube. This is typically done intuitively, relying on visual inspection and manipulation of the pieces. Speedcubers strive to achieve this block with minimal moves and optimal piece placement.
Second Block (SB)
Following the first block, a second 1x2x3 block is built on the right side of the cube. This stage is also predominantly intuitive, with cubers aiming to integrate the second block seamlessly with the already completed first block.
First Two Layers (F2L)
With the two blocks in place, the next step involves orienting and permuting the remaining edges of the first two layers (the top and middle layers). This stage is often algorithm-based, using a set of specific move sequences to manipulate the edges into their correct positions. This contrasts with the block-building focus of the initial stages.
Orient Last Six Edges (OL)
After the first two layers are solved, the Roux method focuses on orienting the last six edges (the edges on the top layer). This stage involves using algorithms to flip the edges into the correct orientation without disturbing the already solved layers.
Permute Last Six Edges (PL)
Finally, the last step is to permute the last six edges, placing them into their final positions. Similar to the orientation stage, this permutation is achieved using a set of algorithms designed to move the edges without affecting the rest of the cube.
The Current World Record and Notable Solves
The official world record for the fastest single Roux solve is constantly being challenged and improved. Tracking these records provides insight into the potential of the method and the skill of top speedcubers. While exact records are subject to change, understanding the level of performance achieved by these cubers is important.
Who Holds the Record?
The current world record for the fastest single Roux solve is held by a select few speedcubers who have dedicated countless hours to mastering the method. These individuals possess not only exceptional finger dexterity but also a deep understanding of the cube and the optimal move sequences.
What Makes a Record-Breaking Solve?
A record-breaking Roux solve is characterized by a combination of factors. These factors include efficient block building, optimal algorithm selection, smooth execution, and a bit of luck in terms of the initial scramble. Even with perfect execution, a favorable scramble can significantly reduce solve time.
Favorable Scramble Conditions
The initial scramble of the cube plays a significant role in determining the potential speed of a solve. A scramble that naturally positions pieces in advantageous locations can allow for faster block building and easier algorithm execution.
Efficient Block Building
Minimizing moves during the first block and second block stages is crucial for achieving fast solve times. Skilled cubers can often identify and execute these blocks with remarkable efficiency, reducing unnecessary moves and saving valuable seconds.
Optimal Algorithm Selection
Choosing the right algorithms for the F2L, OL, and PL stages is essential for minimizing move counts and maintaining fluidity. Experienced Roux solvers have a vast repertoire of algorithms and can quickly identify the most efficient sequence for any given situation.
Smooth Execution
Fluid and precise finger movements are critical for executing the chosen algorithms quickly and accurately. This requires extensive practice and muscle memory development, allowing cubers to perform the moves without conscious thought.
Tips and Tricks for Faster Roux Solves
For those aspiring to improve their Roux solve times, there are several strategies and techniques that can be employed. These strategies range from improving block building skills to expanding algorithm knowledge and refining execution techniques.

The pursuit of faster solve times is a testament to the ingenuity and dedication of the speedcubing community, and the Roux method offers a unique and rewarding path to achieving these remarkable speeds.
What is Roux, and how does it differ from other speedcubing methods like CFOP?
Roux is a speedcubing method for solving the Rubik’s Cube, focusing on block building rather than solving layers as in CFOP (Fridrich Method). Instead of solving the first two layers (F2L) in pairs, Roux solves the first block (1x2x3) on the left face and the second block (1x2x3) on the right face. This approach emphasizes turning specific layers (M, U, R) more frequently than other methods, leading to fewer rotations for skilled solvers.
Unlike CFOP, which relies heavily on algorithms for F2L and last layer, Roux relies more on intuition and look-ahead during block building. The final stages of Roux involve solving the remaining four corners (CMLL) and then permuting the last six edges (LSE). This distinct separation of corners and edges in the last stages is a key differentiator from CFOP’s last layer algorithms.
What is considered a “fast” Roux solve time, and how does it compare to world records?
A “fast” Roux solve time is subjective and depends on the solver’s skill level. Generally, a Roux solve under 15 seconds is considered very good, and anything under 10 seconds is exceptional and approaching world-class level. For beginner Roux solvers, aiming for sub-30 seconds is a good initial goal, then progressively working towards sub-20 and lower as their understanding and fingertricks improve.
World records for Roux singles are constantly being broken, and they typically hover around the 4-6 second range. These records are achieved by extremely skilled solvers with exceptional look-ahead, efficient block building, and precise execution of algorithms for CMLL and LSE. Comparing personal best times to world records provides a benchmark and motivation for improvement, though it’s important to remember the vast skill difference involved.
What are the main advantages of using the Roux method for speedcubing?
One of the primary advantages of Roux is its lower move count compared to CFOP. Because of its focus on block building and fewer full cube rotations, Roux can often lead to shorter solutions, especially for scrambles that are conducive to Roux. This can translate to faster solve times if the solver is proficient in look-ahead and execution.
Another advantage lies in Roux’s greater reliance on intuition and less dependence on memorizing a large number of algorithms. While CMLL and LSE do require learning algorithms, the block building stages allow for more creative problem-solving and a deeper understanding of the cube’s mechanics. This can make Roux a more engaging and rewarding method for some solvers.
What are some common challenges faced by Roux solvers, and how can they be overcome?
A common challenge for Roux solvers is efficient block building. Creating the first two 1x2x3 blocks requires careful planning and execution to avoid creating unsolvable cases later in the solve. This can be overcome by practicing block building techniques, analyzing example solves, and developing strong look-ahead skills to anticipate the consequences of each move.
Another challenge is mastering CMLL and LSE. These stages require learning a significant number of algorithms and developing fast recognition skills. Overcoming this involves consistent practice of the algorithms, spaced repetition learning techniques, and focusing on fingertricks to execute the algorithms quickly and accurately. Efficient transition between CMLL and LSE is also crucial for minimizing pauses and maximizing speed.
What resources are available for learning and improving Roux solving skills?
Many resources are available online for learning Roux, including websites, YouTube tutorials, and online communities. Websites like RouxCubing.com offer comprehensive guides, algorithms, and resources for solvers of all skill levels. YouTube is a great platform for visual learners, with numerous tutorials demonstrating block building techniques, CMLL and LSE algorithms, and example solves from experienced Roux solvers.
Joining online communities like the Speedsolving.com forum or dedicated Roux subreddits can provide valuable support, advice, and feedback. These communities offer opportunities to ask questions, share progress, and learn from other Roux solvers. Practicing with a physical cube and using online timers and analysis tools can also help track progress and identify areas for improvement.
How does the Roux method affect fingertricks and turning style compared to CFOP?
Roux solvers often develop a unique fingertrick and turning style due to the method’s emphasis on M, U, and R layer moves. The M layer, in particular, requires specialized fingertricks for efficient and fluid execution. Roux solvers often focus on developing accurate and controlled fingertricks for these layers to minimize pauses and maximize speed.
CFOP solvers rely more on fingertricks for F2L pairs and full cube rotations, whereas Roux solvers prioritize smooth and precise execution of single-layer moves. The focus on minimizing rotations in Roux also encourages solvers to develop fingertricks that allow them to perform consecutive moves on the M, U, and R layers without regripping or pausing. Overall, Roux typically leads to a more ergonomic turning style that prioritizes efficiency and accuracy over brute force speed.
Are there specific cube brands or types that are preferred for Roux solving?
While any modern speedcube can be used for Roux solving, some cubes are preferred due to their smooth turning, stability, and customizability. Cubes with strong magnetic systems are often favored because they provide better control and prevent overshooting during fast turns, especially on the M layer. Popular brands among Roux solvers include MoYu, GAN, and QiYi.
Preference for specific cube types often comes down to personal preference and individual fingertrick styles. Some solvers prefer lighter cubes with fast turning, while others prefer heavier cubes with more control. It is recommended to experiment with different cube brands and models to find the one that feels most comfortable and allows for optimal fingertrick execution. Adjusting the tension and lubrication of the cube can also significantly affect its performance and suitability for Roux solving.
