Case 4. We have 2 whole ribs and 2 broken ribs


On the White side one rib is whole (Green) and second rib is broken (Blue).	On the Yellow side one rib is whole (Green) and second rib is broken (Blue).

As well, there may be occasions when the White side of the two edges is whole, and the Yellow 2 ribs is broken, or vice versa. But all these cases are resolved the same way.

Hold the any broken rib with your fingers. For example the broken Blue rib on Yellow side. Under such conditions, we will solve second broken pair, in this example it the Blue rib on the White side.

It is pivoted so that we were able to disconnect two elements that make it up.	Disconnect 2 wrong White elements - Red and Orange. Rotate on 180⁰	Put the blue color of the top white element on the Right side. Rotate on 90⁰	Send it to bottom side. Rotate on 180⁰	Put the blue color of the top white element on the face. Rotate on 90⁰

Connect two white elements (with blue color). Rotate on 180⁰	We got the situation 1 whole and 3 broken. Find the whole rib. In this example, it Blue rib on the White side.	Hold the whole rib (in this sample it the Blue rib) with your fingers and use case 1 «1 whole, 3 broken»

Solving the Rubik’s Cube 3x3x3 by method of Valery Morozov

The sequence of solving:

Choose two the opposites of color on the cube, for example White and Yellow. These colors will play the role of basic colors.
Solving 8 corners (this step is equals to solving the 2x2x2 cube). Note that each corner-piece (corner) contains the basic color - White or Yellow:
1. On the top side collect any 4 corners so as to basic color was on top side. For example 3 Yellow and 1 White. Here we do not distinguish basic colors - White equals Yellow.
2. On the bottom side flip 4 corners so as to basic color was on bottom side. Now all basic colors on Top and Bottom sides.
3. Using rotation vertical sides (Right, Left, Front and Back sides) only on 180⁰, and Top and Bottom sides on any angle collect on Top side all corners with White colors and on Bottom side all corners with Yellow colors.
4. Put all corner-piece into right place. In result – all 8 corners solved.
Solving 4 edge-piece (edge) which are in the middle layer (which is between the Top and the Bottom sides). Note that these 4 edges does not contains the basic color. At this phase, we to get rid of these 4 edges. In the result – 4 columns is solved.
Solving the remaining 8 edges, each of which contain the basic color - White or Yellow:
1. Connect any 2 edges, so that they form a correct pair of edges and put it in its place. In the result, we get two of the letter "U". Now remains collect 6 edges or 3 pairs of the edge.
2. Adding any 2 other edges (theirs basic colors must look to up) on the side where the lower part of 2 letters «U» i.e. where their basic colors look to up. In the result, on this side all 4 edges look to up.
3. Do analyze centers and flip 4 edges (their basic colors must look to up) on the opposite side. Calculate how many degrees you need to for to put all centers to place. If you need to make turns on 0, 180, 360 degrees so as to centers stands to place, then need use a combination in which the position of the centers will not change. Else if you need to make turns on 90 or 270 degrees so as to centers stands to place, then need use a combination, that makes an extra twist of the middle layer of 90⁰.
4. Connect 6 edge so as to they formed 3 correct pairs.
5. Put 3 pairs to place.
Put centers to its place. The cube 3x3x3 is solved!

Phase 0. Choose two the opposites of color on the cube

Opposite colors on the classic Rubik's cube is White and Yellow, Red and Orange, Blue and Green. You can choose any of these pairs of colors. In this manual I use White and Yellow colors as basic colors.

Phase 1. Solve corners

Step 1.1. Collect on the top side 4 any basic colors

This step is very simple, it should not cause too much difficulty.



In this example we have on Top side 3 White and 1 Yellow colors. You can get a different combination, for example 2 Yellow and 2 White colors. Here we do not distinguish basic colors - White equals Yellow.

Step 1.2. Flip the 4 corner-pieces so as to basic color was on bottom side

Turn over the cube, taking it over the opposite side relative to that on which we have collected 4 base colors on phase 1.

Here we can get only 6 situations, when not all corners on the opposite side stands with basic color to up (the location of the invisible to us the basic colors are marked with yellow stripe):
