Lovers of puzzles are where to express yourself. There are many desktop games, computer programs and tasks. Do not forget about the classics - Rubik Cube. This puzzle fell like a not one generation. That's just folded the cube correctly, it turns out not to all. To learn this, you should start with a simpler version - a cube format 2 * 2.
A little story
The famous puzzle was created by the Hungarian interior design teacher by Erno Rubik in 1974. Popularity and world fame came to the invention not immediately. Initially, Rubik and did not count on the demand of his project. He created a cube to vividly show his students how the theory of mathematical groups and modeling is working.
Students became the first users of the puzzle. Rubik did not immediately paten his creation. At that time, in Socialist Hungary, the facility was not developed. This happened only in 1975. And even then the cube was in no hurry to buy.
Initially, the puzzle had a greater number of multi-colored faces in its design. But for convenience, Rubik reduced them to 54 pieces. The main fastening cube consisted of a mechanism that was associated with other cubes. At the same time, he allowed them to rotate relative to each other. This design is very interested buyers. Rubik's cube moved from the category of acknowledged engineering creation to an exciting puzzle - toy.
It is possible that the work of the Hungarian engineer would remain within Hungary if he had not noticed a German computer entrepreneur. He was fascinated by a cube and, together with his comrades, the famous inventor of the Games contributed to the promotion of the invention.
In the 1980s, Rubik's cube became extremely popular. He was presented as a souvenir, gave birth to holidays and bought children. It was difficult to submit a modern man who would not have this puzzle. That's just managed to gather it not to everyone. Therefore, special schemes and formulas appeared, on the basis of which it was possible to promptly fold all the face.
How to collect Rubik 2 * 2 cube: phased performance and scheme
Puzzle format 2 * 2 The easiest. Those who collect a more complex model 3 * 3 will quickly cope with the task.
The whole process can be divided into three stages. Each stage is divided into several more subteps. At first, the occupation seems difficult and incomprehensible, but with experience comes and awareness of the whole scheme.
Step number 1 - assembly of the bottom layer of the cube
Before you start assembling, you should understand the main terms and abilities of turning the faces. There is a special combination of "FIF PAF", which implies a certain reversal of the faces.
The combination consists of 4 movements:
- up;
- left;
- way down;
- right.
Collect the cube is needed from the bottom layer, it will consist of white faces. This is the easiest and most understandable method. In the future, when experience is more, you can start with any color.
To do this, find a green-orange-white cube, and install it with white down. It can be any other, but most importantly, in place exactly white color.
On the right there will be a cube with the same color set (green, orange, white). It also needs to install a white face down. To do this, with the help of rotational movements, you need to find a suitable element and install it on the right face.
When the element is not in its place and it needs to be omitted, a combination of "FIF PAF" should be made. Then all the elements will take their place.
It will turn out that two white and two orange cubes will be collected.
Now we are looking for another cube with a white face, for example, blue-white. With the help of rotation of the upper face you need to install it so that the white look up, and the blue is right. Then you need to use "FIF PAF" 3 times and a white cube go down, and two blue will be silent.
Step number 2 - assembly of the top layer
Now you need to find a red white corner. White color will be directed to the right, and red - straight. It is necessary using "FIF PANF" to set white cubes to white, and red to the red. It will work out by doing a combination once.
At this stage, you need to pay attention to the corners and correctly set them out. Make it will help the combination: frontal (front) edge - left, upper - right, and frontal - right.
By the time, when it is necessary to make such a manipulation, two angle must be coincided. And such a scheme will allow the rest of the corners to collect.
Stage No. 3 - Assembly of the Yellow Layer
- At this stage, the white surface is assembled. You need to put a cube so that it turns out to be up. The bottom will be assembled from yellow cubes.
- To do this, we find the desired element with a yellow color and with the help of "FIF PAF" omit it down. Now you need to pay attention to the right angle. There is still no yellow there, but you can again do a familiar combination 3 times, and two yellow elements are near.
- Do not turn over the design (white face at the top), thus collect two other yellow cubes.
- Now you need to turn the paired cubes so that all the edges were a certain color.
- With the help of the method "White top - yellow bottom" Cube Rubik assembled.
Where can I show yourself?
Those who have learned to quickly collect different variations of the Rubik Cube can show themselves at special competitions in speedcondigu. Participants on them are collecting the design. Such an event has many directions: assembling models 2 * 2, 3 * 3, etc., assembly for a large number of cubes for a certain time or even assembly blindly.
To participate, you just need to leave a request on the competition website and come at the appointed time.
Rubik's cube performed a furyor in the world of puzzles. He showed that this occupation is obscure, but very fascinating. Also this is an example for novice designers - the creation of the master can conquer the whole world, if you strive for this.
