1.1 Magic Cube Axes and Shapes
Preface
The Magic Cube article in this issue may be a bit long, but it's worth reading! ! !
Next, Xiaoxin will edit more professional Rubik’s Cube knowledge for everyone! I believe that the fans of the public account include big names in the Magic Cube circle, as well as friends who are new to Magic Cube. I hope that the following articles can bring you substantial expansion of Magic Cube knowledge!
If the editor missed mentioning the Magic Cube, you can leave a message or send a private message to the editor! Provide corresponding supplements, and the editor will also make corresponding rewards!
The reason why the title is version 1.1 is to get the interaction and support from the majority of demon friends. Maybe there will be more new articles such as 1.2, 1.3 and so on in the future! ! !
Text: Magic Cube Classification
After Magic Cube became popular around the world, all kinds of strange Magic Cubes have sprung up like mushrooms after a spring rain. There are two mainstream classification methods: classification according to the number of structural axes and classification according to shape. Others include equal-order Magic Cubes and unequal-order Magic Cubes. Transformed and non-transformed Magic Cubes, bundled, conjoined, mixed. . .
According to the axis number structure of the Magic Cube, it can be divided into six categories:
● Bipolar category: sq1. . .
● Four-axis category: Pyramid. . .
● Six-axis category: regular-level Magic Cube. . .
● Eight-axis category: Eight-axis dinosaur cube. . .
● Twelve-axis category: Five Magic Cube. . .
● Other categories: three-axis type, five-axis type, seven-axis type, multi-axis type, zero-axis type [(hollow type, track type) are actually ordinary shaft types with the axis removed and the track design changed].
● Bipolar category: sq1. . .
● Four-axis category: Pyramid. . .
● Six-axis category: regular-level Magic Cube. . .
● Eight-axis category: Eight-axis dinosaur cube. . .
● Twelve-axis category: Five Magic Cube. . .
● Other categories: three-axis type, five-axis type, seven-axis type, multi-axis type, zero-axis type [(hollow type, track type) are actually ordinary shaft types with the axis removed and the track design changed].
According to the shape of the Magic Cube, it can be divided into ten categories:
Tetrahedron, hexahedron, octahedron, dodecahedron, icosahedron, sphere, cylinder, rhombus, star, others.
The editor believes that it is more scientific to classify Magic Cubes according to the number of axes, because their structures are similar and the solutions will be the same. Various solutions are also expanded on the basis of the original coaxial Magic Cube!
Text: Explanation of the six-axis Magic Cube
In real life, most of the Magic Cubes we encounter are third-order Magic Cubes. In fact, there are many members of the Magic Cube race. Some of them can't even be seen as Magic Cubes from their appearance, but they are actually a Magic Cube series of toys. There are so many variations of the Magic Cube and the speed of change is unpredictable. Listed below are the most famous and most recognized Magic Cubes.
This type of Magic Cube maintains its original square shape, and strictly stipulates that the side lengths of each peripheral block must be the same. In fact, the side lengths of Magic Cubes of different orders do not increase year-on-year. The higher the order of the Magic Cube, the shorter the side length of each piece. In order to be more in line with actual human body applications, high-level Magic Cubes often add extra edges on the outermost edges. Wide, easy to hold in hand!
Second-level Magic Cube: The official English name is Pocket Cube, and the Chinese literal translation is called "Pocket Magic Cube". It has two squares on each side. One official version of the Magic Cube has a side length of 40 mm, and the other axis-type second-order Magic Cube developed by Mefferts is 47 mm. The total number of changes in the second-level Magic Cube is 3,674,160. The current fastest record is Teodor Zajder, a 7-year-old Polish Magic Cube who broke the single world record in 0.43 seconds.
Third-order Magic Cube: The official English name is Magic Cube, which is named after Professor Rubik. It has three squares on each side. The official version of the Magic Cube has a side length of 57 mm. The total number of variations of the third-order Magic Cube exceeds 4 trillion, but the single world record held by the Great Park is 3.13 seconds. The Magic Cube is not just a toy. Simple.
Fourth-level Magic Cube: The official English name is Revenge Cube, which literally translates to "Revenge Cube". The fourth-order Magic Cube is much more complicated than the third-order Magic Cube. Its composition is divided into two categories. The first category is a sphere in the center, and each small peripheral piece is connected to the slide rail of the central ball. When rotating, it will move along the The force direction slides on the slide rail; the second type is the fourth-order Magic Cube with the axis as the core. The composition of this type of Magic Cube is very complex. In addition to the central ball and peripheral blocks, there are many additional parts. For racing sports, the second-order fourth-order Magic Cube moves quickly and is not easy to get stuck during high-speed rotation. The single world record as of January 2024 is 16.79 seconds, held by American player Max Park.
Level 5 Magic Cube: The English name is Professor's Cube or Rubik's Professor, which literally translates to "Professional Magic Cube" and is a 5×5×5 cube structure. Invented by Udo Krell. The fifth-level Magic Cube has a total of 8 corner blocks, 36 side blocks (two types) and 54 center blocks (48 blocks are movable and 6 are fixed). Since the structure of the fifth-level Magic Cube is similar to that of the third-level Magic Cube, some of their solutions can be used to help with the recovery. The fifth-level Magic Cube Speed Twist is one of the official racing events of the World Magic Cube Association (WCA). The single world record as of January 2024 is 32.60 seconds, held by American player Max Park.
Sixth-level Magic Cube: The Sixth-level Magic Cube is produced by the Greek Olimpic Cube Company. The cube itself is not very well evaluated. A common evaluation is that it is easy to pop (flying edge: refers to the situation where some components of the Magic Cube are separated from the Magic Cube during restoration. If it appears in the competition as an invalid recovery process), the central axis is not strong, etc... The sixth-order Magic Cube (English: v-cube 6) is a 6×6×6 cube structure. Some solutions to the first-order Magic Cube and the fifth-order Magic Cube to help with recovery and transformation. The single world record as of January 2024 is 59.74 seconds, held by American player Max Park.
Seventh-level Magic Cube: The English name is v-cube 7; with its unique shape and genius design, the seventh-level Magic Cube has collection, appreciation and practical value. The seventh-level Magic Cube is also difficult to restore. The World Cube Association (WCA) made the seventh-level Magic Cube Speed Twist an official competition in 2009. The single world record as of January 2024 is 1 minute and 35.68 seconds, held by American Max Park.
Every time a new high-level Magic Cube is invented, it takes a long time, because not only the feasibility of the project must be considered, but also whether the Magic Cube can be stably used for rotation after it is made. Yuxin is committed to developing more new Magic Cube products! ! ! Which type of Magic Cube are you looking forward to more? ! ! Please leave a message! ! !
The next issue will explain the four-axis Magic Cube: the main representative is the Pyramid Magic Cube, so stay tuned!
