How to collect a 4x4 Rubik's Cube. Schemes and recommendations

A great lesson for the hands and head is a puzzle. They develop memory, logic, motor skills, they learn to focus attention and relax - in general, they are very useful, both for children and adults.

Take yourself for the rule of holding breaks at work not for a cigarette or a cup of coffee with a donut, but with a puzzle in hand. Very soon you will notice how well you feel, the appearance pleases, the brain began to work clearly and quickly - all this will certainly affect the improvement of your psychological, mental and financial state. The most compact (it will go even into a handbag), popular and entertaining for many years a puzzle - this is a cube Rubik.

Varieties

In the late eighties of the XX century the Hungarian sculptor Erno Rubik patented the world's most sold puzzle - a magic cube (or Rubik's cube - among the people). And since then it can be found in almost every home. Both children and their parents are happy to twist and twist the "smart" toy, trying to collect scattered on the sides of multi-colored elements in one picture. True, not everyone succeeds. The trick is that you need to know the assembly scheme. Today we will talk about how to work with a 4x4 model.

To understand how to assemble a 4x4 cube, you need to represent the construction of its ancestor - the 3x3 model - in space. It has three internal axes around which outer elements rotate - twenty-seven cubes. The face includes nine squares of the same color, only 6 faces - 6 colors.

There are instances with beveled faces and elements of various shapes and sizes, for example, squares and rectangles in one die. For children on the squares draw pictures of the frills, as in puzzles, which makes the assembly more interesting, but much more difficult. For adult lovers of the Rubik's cube, the figures are applied to the squares, that is, it is not enough to collect the faces by the colors, it is also necessary that the figures are in the correct order on each of them.

To date, there are many modifications - 2x2, 4x4, 7x7 and even 17x17! There are championships for collecting Rubik's cube for a while. Professionals surprise others by the ability to collect a puzzle without looking! The last record of high-speed assembly put the Pole - 8.65 seconds, the Italian collected a cube with one hand for 9.43 seconds. With closed eyes, he collects this immortal toy countryman of its creator for 26.36 seconds. The shortest way to the right result is twenty moves. The most original performance is leg assembly in 27.93 seconds!

But we still try to figure out how to collect a 4x4 Rubik's cube. Immediately make a reservation: you can learn to work with this model for those who have the skills to collect its predecessor - a 3x3 cube.

Basic rules of assembly

The main goal at the preparatory stage is to bring a 4x4 cube to a 3x3 cube, then assembling a 4x4 Rubik's cube will become much easier and more understandable. To do this, you must first collect the centers of the cube - these are 4 inner squares of the same color.

Important! The 4x4 form does not have a fixed center, that is, you will have to arrange the colors (central fours) yourself. Further, if only the outer edges are rotated, the location of the centers will not be disturbed.

After you place the centers in places, the same must be done with the rib pairs or corner elements. By displacing the outer faces, we expose the cube so that when the pair of left or right edges of the puzzle rotates, the elements on the edges converge.

After solving this problem, the question "how to assemble a 4x4 cube" will no longer seem so difficult - it's almost a 3x3 cube, so we use known formulas, methods and techniques.

Parities

But on the last spins there can be parities - complex situations in which color squares can be placed incorrectly, and there are no such precedents in a 3x3 cube.

Years of experience and diligence puzzle lovers led to the identification of all possible parities and the development of an algorithm for solving these problems.
