There is some doubt about which is the hardest Rubik’s Cube of all: God’s Number 3x3x3 or the 17x17x17.
Although God’s Number specifically relates to the 3x3x3 Rubik’s Cube, it can be stated that solving a 17x17x17 Rubik’s Cube is generally more challenging due to its larger size and complexity.
The Rubik’s Cube is a puzzle invented by Professor Erno Rubik from Hungary. He created the first version of the cube in 1974. Initially, Rubik designed the cube to help his students understand three-dimensional challenges. He soon realized that his invention was also a challenging puzzle! The Cube was initially called the Magic Cube, but this was later changed to Rubik’s Cube when it became popular worldwide as a speedcube. In 1980, the Rubik’s Cube was officially launched at an international toy fair and quickly grew into a global phenomenon.
Over the years, many different people have contributed to the cube, but one of the first designers is Erno Rubik, a professor from Hungary who initially made it from 27 wooden blocks in 1974 for his students to explain a mathematical topic. Rubik was not sure if there was a solution, so it took him a month to solve the puzzle himself first.
People unfamiliar with speedcubes often refer to them as Rubik’s cubes. Rubik’s is a brand in its own right and is a challenging puzzle shaped like a cube, where each face has a unique color. Typically, each face consists of 3 rows and 3 cubes.
A cube always has 6 sides, regardless of its size. Each side of a cube is a square face. So, regardless of whether a cube is 3×3 or another size, it will always have 6 sides. However, the size and number of blocks inside the cube can vary.
A Rubik’s Cube features six unique, vibrant colors that each perfectly match the different sides of the cube.
At an exciting event in Long Beach, a young participant from California amazed everyone by solving the 3x3x3 cube in an incredible time. With an astonishing new world record time of just 3.13 seconds, Max Park has proven himself to be a true speedcube champion. This achievement is a full 0.34 seconds faster than the previous record, which had remained undefeated for over 4 years.
Solving a cube takes patience, practice, and perseverance! By consulting various resources such as our blog, videos, and books, and learning from experienced cubers, you can improve your skills. Experiment with different techniques and algorithms to get better. It is also helpful to take notes to keep track of your steps while solving. Remember to enjoy the process and the challenges involved in solving the cube. Making mistakes is human and is part of the learning process. Therefore, stay focused and, above all, do not give up, even when things get difficult. The best cubers in the world also started at step 1. By persisting, you will get better and better and develop the skill to solve the cube effortlessly. Every solved cube will give you satisfaction and motivate you to continue. Remember that the journey of solving a cube is just as valuable as the end result. Enjoy the challenge, improve your mental sharpness, and develop a sense of satisfaction as you solve the cube step by step.
So go for it, keep practicing, and solve that cube!
With speedcubes, it is all about fast and smooth movements, and manufacturers have developed various mechanisms to optimize the performance of these cubes. Let’s explore the most common mechanisms:
Ball-core Mechanism: Uses a spherical core in the center of the cube. This core provides stability and ensures smoother rotations as the pieces rotate around the sphere. Although this technique may be somewhat more complex to manufacture and may feel slightly heavier for some users, this mechanism also helps reduce jamming during rotation.
Maglev Mechanism: Maglev stands for magnetic levitation and replaces traditional springs with magnets. This significantly reduces internal friction, resulting in very smooth and quiet movements. Furthermore, magnetic levitation ensures more even tension within the cube. Although this mechanism is very advanced, it can also be more expensive, and some users require an adjustment period to get used to the absence of traditional spring resistance.
Magnetic Mechanism: integrates small magnets into the individual pieces of the cube. These magnets attract each other and ensure that the pieces click precisely into place during rotation. This provides clear tactile feedback and ensures stable, fast movements, minimizing unintended rotations and overshoot (a situation where a turn goes further than intended). Although the magnetic mechanism may make the cube slightly heavier due to the presence of the magnets, they provide a significant improvement in stability and precision.
Enhanced-core Mechanism: Includes improved internal structures that utilize innovative materials and designs to enhance the overall performance of the cube. These mechanisms offer improved durability and accuracy, especially at higher speeds. Enhanced-core mechanisms reduce friction and wear, resulting in a smooth and consistent experience over time. Additionally, they provide improved stability, minimizing the risk of pops (where pieces fly out of the cube). Although the complexity and cost of these mechanisms may be higher, they increase the use value due to their improved performance and durability.
UV Coating: A popular choice is the UV coating. Although they may be somewhat smoother, these cubes feel premium. A UV finish is a specific type of glossy coating achieved by applying a special lacquer that is then cured under ultraviolet (UV) light. In addition to a glossy appearance, the UV finish offers extra protection against scratches and wear, making the cube very durable.
Frosted: A frosted appearance is a slightly rough, grainy finish with a subtle and soft form of sheen. This texture makes fingerprints and stains less visible, offers better grip, and increased durability against scratches and wear.
Matte: A speedcube with a matte finish has a flat, non-glossy surface that is consistent and uniform in texture and appearance, without variations or irregularities, and a finish that is completely non-reflective. This texture reduces the visibility of fingerprints and stains, offers extra grip, and ensures a calmer visual appearance without reflections.
Black: Traditional speedcubes often feature black plastic bases, creating a strong visual contrast with the colored stickers. Stickers offer many customization options but can wear off or come loose over time. As an alternative, many cubers opt for stickerless cubes, which use colored plastic pieces and eliminate the risk of sticker wear. These remain clear and easy to maintain, although some competitions once had restrictions on their use.
Primary: For a more subtle appearance, there are cubes with primary plastic – light grey or off-white base plastic – that offer a more muted look. Although the visual contrast with the colored faces is less sharp than with black cubes, they do have a unique and attractive aesthetic.
Gummy: Additionally, there is the gecko texture, also known as a gummy finish. This rubbery coating provides extra grip, which is especially useful for cubers with sweaty hands. This ensures better control while rolling, although it may feel a bit sticky to some users.
Glossy: Another popular choice is the glossy finish, which provides a shiny and reflective surface. Although visually appealing, a glossy finish may offer slightly less grip compared to matte or rubberized finishes.
Jelly: Jelly speedcubes distinguish themselves through their unique and striking aesthetic. These cubes feature a translucent, pastel-colored finish that gives them a fresh, colorful look. The brightly colored, semi-transparent sections make the cube visually appealing and playful. Despite their distinctive appearance, jelly cubes offer the same texture as standard plastic cubes, without the extra grip of a gummy finish. For speedcubers looking not only for performance but also for a cube that looks unique, jelly cubes are a perfect choice.
Metallic: For those seeking something truly unique, there is also a metallic coating. These provide a striking shine and a distinctive look; they are primarily for decorative purposes and are not standard in the speedcubing world.
