Great activity for hands and head - puzzles. They develop memory, logic, motor skills, teach you to focus and relax - in general, they are very useful, both for children and adults.

Make it a rule to spend your breaks at work not with a cigarette or a cup of coffee with a donut, but with a puzzle in your hands. Very soon you will notice how you feel good, your appearance pleases, the brain began to work clearly and quickly - all this will certainly affect the improvement of your psychological, mental and financial condition. The most compact (it even fits into a lady's handbag), popular and entertaining puzzle for many years is the Rubik's Cube.

Rubik's Cube 4x4

Varieties

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

To understand how to solve a 4x4 Rubik's cube, you need to imagine the design of its ancestor - the 3x3 model - in space. It has three internal axes around which external elements rotate - twenty-seven cubes. The face includes nine squares of the same color, a total of 6 faces - 6 colors.

There are instances with beveled edges and elements of various shapes and sizes, for example, squares and rectangles in one cube. For children, fragments of pictures are drawn on the squares, as in puzzles, which makes the assembly more interesting, but much more difficult. For adult lovers of the Rubik's cube, numbers are applied to the squares, that is, it is not enough to collect the faces by color, you also need the numbers to be in the correct order on each of them.

Today there are many modifications - 2x2, 4x4, 7x7 and even 17x17! Timed Rubik's Cube solving championships are held. Professionals surprise others with the ability to assemble a puzzle without looking! The last record for speed assembly was set by the Pole - 8.65 seconds, the Italian collected the cube with one hand in 9.43 seconds. With his eyes closed, this immortal toy is assembled by a fellow countryman of its creator in 26.36 seconds. The shortest way to the correct result is twenty moves. Most original performance - leg assembly in 27.93 seconds!

But we will still try to figure out how to solve a 4x4 Rubik's Cube. Let's make a reservation right away: those who havethe skills of collecting her predecessor - the 3x3 cube.

Basic assembly rules

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

Important! The 4x4 shape does not have a fixed center, that is, you will need to arrange the colors (central fours) yourself. Further, if you rotate only the outer edges, then the location of the centers will not be violated.

After you put the centers in place, the same must be done with edge pairs or corner elements. By shifting the outer faces, we expose the cube so that when a pair of left or right faces of the puzzle is rotated, the elements on the edges come together.

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

Parities

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

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