What Rubik’s Cube Is Used in Competition

Rubik’s Cube competitions have become increasingly popular in recent years, with thousands of participants competing globally. To compete at the highest level, it is essential to understand the different types of Rubik’s Cubes used in competition. The standard competition cube is the most commonly used, but variations such as the speedcubing and magnetic cube have also gained popularity. Additionally, some contests allow non-WCA (World Cube Association) cubes, which can offer unique advantages for certain events. This article will seek the different types of Rubik’s Cubes used in competition and their characteristics.

The Standard Competition Cube

The standard competition cube is the most commonly used cube in Rubik’s Cube competitions. It is recognized by the World Cube Association (WCA) and is used for official WCA events such as 3×3, 4×4, and 5×5 cube solving. The cube has the following characteristics:

A. Size and weight

  • The standard competition cube measures 56mm on each side
  • It weighs approximately 80 grams

B. Structure

  • The cube has six faces, each with nine square stickers of different colours
  • The centrepieces are fixed in place and never move
  • The corner and edge pieces are able to move and can be manipulated to solve the puzzle

C. Mechanism

  • The standard competition cube mechanism consists of a core, screws, springs, centrepieces, edge pieces, and corner pieces.
  • The cube is designed to be easily manipulated and has smooth turning.

Variations of the Competition Cube

Several variations of the competition cube have gained popularity in recent years. These cubes offer different characteristics and advantages over the standard competition cube. Below are some of the most popular variations:

A. Mini cube

  • The mini cube is a smaller version of the standard competition cube
  • It measures 50mm on each side and weighs approximately 60 grams
  • The smaller size can offer advantages for people with smaller hands or those who prefer a lighter cube

B. Big cube

  • The big cube is a larger version of the standard competition cube
  • It measures 65mm on each side and weighs approximately 150 grams
  • The larger size can offer advantages for people with larger hands or those who prefer a heavier cube

C. Square-1

  • The Square-1 is a cube with a different shape than the standard cube
  • The WCA recognizes it and has its own events
  • It is made up of a series of pieces that can be twisted and turned to solve the puzzle.

Speedcubing Cube

The speedcubing cube, also known as the “speed cube,” is a type of Rubik’s Cube that is designed for speedcubing competitions. It has several characteristics that make it different from the standard competition cube, including:

A. Structure

  • The speedcubing cube has a smoother and more flexible structure than the standard cube
  • The pieces are designed to move more easily and quickly, allowing for faster solving times

B. Material

  • The speedcubing cube is often made of a smoother plastic material than the standard cube
  • This allows for easier turning and reduces friction between the pieces

C. Magnets

  • Some speedcubing cubes come equipped with magnets, which help to align the pieces and reduce locking or popping
  • Magnetic cubes are especially popular in events such as 3×3 cube solving

Overall, the speedcubing cube is designed to be faster and more efficient than the standard competition cube. Many professional speedcubers prefer the speed cube for its smoothness and ease of use. 

Magnetic Cube

The magnetic cube is a type of Rubik’s Cube that has recently gained popularity. It is similar to the speedcubing cube but with small magnets placed inside the cube to improve performance. Here are some characteristics of the magnetic cube:

A. Structure

  • The magnetic cube has a similar structure to the speedcubing cube
  • The addition of magnets helps to align the pieces and reduce the chance of locking or popping

B. Magnet strength

  • Magnetic cubes come in different magnet strengths, with stronger magnets providing more stability and less chance of misaligning the pieces.
  • The magnet strength can be adjusted by adding or removing magnets, allowing for customization based on personal preference.

C. Price

  • Magnetic cubes are generally more expensive than standard or speedcubing cubes due to the added materials and technology.
  • While the WCA does not recognize the magnetic cube and is not allowed in official WCA events, it has become popular among speedcubers for its improved performance and stability.
  • In some non-WCA circumstances, the magnetic cube may be allowed, providing a unique advantage for those who use it.

Conclusion

In conclusion, Rubik’s Cube competitions use different types of cubes that offer various advantages and characteristics. The standard competition cube is the most commonly used, but variations such as the speedcubing cube and magnetic cube have also gained popularity. Understanding the different types of cubes can help participants choose the cube best suited to their preferences and skill level.
