I recently came across an interesting Rubik's cube and decided to make a post about what kind of Rubik's cubes there are.
The most difficult Rubik's Cube
If solving the classic Rubik's Cube is not a problem for you, try this monster cube called Petaminx. It consists of 975 parts, and comes with 1212 stickers with flowers that need to be pasted on its edges. Designer Jason Smith spent 75 hours creating this cube. Just imagine how long it will take to solve it.
Sudocubic
This is a hybrid of a Rubik's Cube and the game Sudoku. Numbers are drawn on the edges, and you need to fold the cube so that the sums of the numbers on them are equal. If you are a Sudoku fan, this toy is for you!
Light cube
This cube has no moving parts, and all segments are illuminated by LEDs of different colors. To “rotate” you need to click on the corresponding buttons on the edges, and they will change their color accordingly. In addition to the Rubik's Cube, there are several more in this puzzle logic games, related to flowers, and even a game similar to Minesweeper on Windows.
Rubik's ball
If you make a Rubik's Cube into a ball, you get an IQ Sphere. Its diameter is 70 mm, and its weight and texture allow it to be used as a souvenir or paperweight. When you need to take a break from work, you can take this ball and stretch your mind
Rubik's Cube 2.0
There are no colors in it at all, all the fragments differ only in size, and besides this, their internal surfaces are mirrored. It’s so difficult to fold it at first!
Non-Rubik's Cube
The translation of the title is mine, free. THIS is called the Irregular IQ Cube. From the state on the left in the photo, you need to fold the cube exactly “into the shape of a cube.” And it's not as easy as you might think...
Rubik's pyramid
Another name for this puzzle is Pyraminx, and when assembled it is similar to the game “Snake”, also known in childhood. Someone came up with the idea of combining the form of one toy with the content of another, and what you see in the photo turned out. Very mind-blowing
Super Mario Cube
This cube is somewhat similar to a Sudoku cube, only instead of a number, when collecting this cube, you need to create a puzzle based on the immortal game.
The official name of the new puzzle is Rubik 360. Its essence is to transport a certain number of colored balls from the transparent inner sphere to their corresponding cells on the outer sphere. They get there through the middle sphere, which has only two holes.
Hungarian professor Erno Rubik, the inventor of the famous cube, speaks of his new brainchild: “360 is one of the most innovative and exciting puzzles since the invention of the cube. Solving it will require skill, logic and dexterity.”
Braincube
Well, the last, real-life cube, the work of designer Jason Freeny, is made in the shape of a brain.
How can you come up with the idea of creating the smallest Rubik's cube in the world? Only after creating the largest Rubik's cube in the world! In 2016, British puzzle lover Tony Fisher was able to build the most big cube Rubik in the world with a side length of 1.57 meters and a weight of more than 100 kg.
Almost all the parts in the Rubik's cube are made of plastic with the exception of the mechanism for turning the faces.
It took Tony Fisher about two months to assemble the giant. This record was officially presented in the Guinness Book of Records.
In 2017, having decided that it would be more surprising O a larger cube would not be so interesting, Tony Fisher decided to go in a different direction and created the smallest Rubik's cube in the world.
Made using a 3D printer, the cube has a side length of only 5.4 mm. But if colored stickers are glued to it, the length increases to 5.6 mm. However, this does not prevent it from being considered the smallest in the world - the previous record holder has a side 0.3 mm longer.
However, Tony Fisher is not going to submit an official application for recognition of a new world record this time. According to him, the created Rubik's cube has some disproportion, so the model needs additional improvements. In addition, the creator of the miniature cube fears that copyright issues may arise when filing an application - after all, his creation is based on a model of another mini-Rubik's cube, which Tony Fisher was able to reduce.
Incredible facts
On the eve of May 19 The famous puzzle "Rubik's cube" turns 40 years old. In 1974, a young architecture teacher Erne Rubik from Budapest created an almost impossible object.

The puzzle consisted of 26 unique miniature cubes. This includes hidden internal ridges that engage with other cubes while allowing them to rotate.
The Magic Cube was renamed the Rubik's Cube in 1980 in honor of its inventor.

The number of types of Rubik's cubes today is difficult to count. However, among all the variety we can distinguish classic models, with images on the edges, hybrids unusual shape, mirror and virtual. Some models can be easily found on store shelves, others can be ordered in an online store, and others remain at the prototype stage.
Considering all the options for the Rubik's Cube, it’s hard to believe that it all started with one simple model in the mid-80s of the last century. It was then, in 1974, that the Hungarian sculptor Ernő Rubik invented and in 1975 patented a puzzle, which is a 3×3×3 plastic cube with 54 visible colored faces.

The Rubik's cube is considered the most popular toy in the world, which has sold a total circulation (original + analogues) of about 350 million copies. However, puzzles are sold around the world under more than one name. In the original version, Rubik’s invention is called the “magic cube”, a name that stuck in Hungarian, German, Portuguese and Chinese. In Hebrew, the Rubik's cube is called the “Hungarian cube.”
The most popular Rubik's Cube models
It is worth mentioning that not all of the puzzles presented are Rubik's cubes. Some models were even invented before 1974, but Rubik is undoubtedly responsible for their spread.

The history of this entertaining puzzle begins in 1974, but to this day its popularity has not diminished at all. On the contrary, people are inventing more and more new ways to complicate the toy or make it original. Today we will talk about the largest Rubik's cube in the world.
A little history
In 1974, Erne Rubik, a thirty-year-old architecture teacher from Budapest, did not even imagine that his destiny was to soon become a millionaire. He was seriously interested in geometric problems and 3D modeling, and he had been thinking about the design of the future cube for several years.
The first product consisted of 27 small wooden cubes with colored edges. With his help, Erne tried to explain to his students the basics of mathematical group theory. The purpose of the invention was that individual cubes should rotate independently without disturbing the overall structure.
The total number of faces in the first version was 156, but later the creator reduced this number to 54. Then the product began to look exactly the way it looks today. Instead of one cube, a special connecting mechanism was placed in the middle, which turned the invention into a toy.
Everyone who knew Rubik liked the idea, and he soon decided to patent it. The first batch of cubes on an industrial scale was released in 1977, several copies also ended up in Soviet Union. But the West was not conquered immediately.
Popularity came from the moment when computer businessman from Germany Tibor Lakzi began promoting the toy. Today, the Rubik's Cube is a must-have item on the shelves of any toy and puzzle store. Entire championships are held to collect it.
The product consists of huge amount small cubes - the length of each side is 33 elements. It was made using 3D printing technology by Gregoire Pfennig, a fairly famous puzzle creator in the world. Previously, he had already implemented more than a hundred projects of varying complexity.
And the giant Rubik's cube is far from the most complex and time-consuming among them. However, it can take a person several thousand hours to assemble it. The internal structure of the product consists of seventeen layers, and each one moves in relation to the others.
The total number of elements of the toy, if you can call it that, is 6,153, all of them are made on an automated machine under digital control (or SNS). The machines were provided by the organization 3D Print Fabriek, which also sponsored the production.
It took Gregoire about two hundred hours to assemble the cube, but it should be taken into account that he did this not alone, but with several assistants. The same amount of time was spent gluing labels to each part. Only then could the cube be considered ready. The area of one side is comparable to the area of a chessboard.
The cube is available to order from Olivier's Sticker Shop and retails for $18,000. In addition, the products are out of stock, after ordering you will have to wait 3-4 months until it is produced.
A Dutch engineer invented a type of toy that included more than one and a half thousand elements (17x17x17). Oscar had previously been known for his extraordinary puzzles, but in this case he clearly wanted to amaze the whole world.
Before that, he had already created unusual Rubik's cubes from 3x3x3 to 11x11x11, but they did not gain much fame. It took 1.5 thousand pounds sterling and 60 hours of real time to create a copy.
The length of the side of the cube is 140 mm, the total number of elements is 1539. The parts were printed on a 3D printer and hand-painted in the desired colors. The painting process alone took over ten hours.
Oskar van Devent solves a regular Rubik's cube in 2 minutes, but he has not yet discovered the algorithm for solving his own invention.
To mark the 40th anniversary of the invention of the popular puzzle in 2014, the jewelry company Diamond Cutters International released its own interpretation of it. The toy was created from yellow gold No. 750, and there are dozens of precious stones in an inconspicuous frame.
Different stones were used to color the individual sides: amethysts, diamonds, rubies, sapphires and emeralds. This piece of jewelry required 8,500 hours to complete. The total cost can be approximately estimated at $2,500,000.
The product was first presented at an American exhibition called Beyond Rubik’s Cube, held in New Jersey. But even after this, it did not remain an unclaimed cargo, and to this day travels to a variety of world exhibitions.
It is worth mentioning here the merits of our compatriot, Russian E. Grigoriev, a programmer from Cheboksary. He is a big fan of this toy and can assemble it in just a minute.
But one day a 40-year-old man came up with the idea to complicate and diversify his task, and at the same time get into the pages of the Guinness Book of Records. Over the course of a month, Evgeniy made a toy using a laser. The result was a product with a side length of only one centimeter.
According to the creator, solving the puzzle has indeed become more difficult - now it takes as much as 3 minutes.
Custom Rubik's Cubes
In addition to the usual square products, differing only in the lengths of the sides, there are also very interesting varieties of puzzles. Let's look at a few of them:
Puzzles are a great way to develop your mental capacity and hand motor skills, train logical thinking. Therefore, we strongly recommend that you learn to play with one, or even several of the listed unusual toys.
