How does such a Rubik s Cube go to the top level?

The yellow side blocks facing up are placed on the front and right, the first two layers are turned 90 degrees clockwise, the right layer is 90 degrees, the upper layer is 90 degrees, the right layer is 90 degrees inverse, the top layer is 90 degrees inverse, the first two layers are 90 degrees inverse, and then the top layer becomes a cross.

Look at the corner block again, divided into several situations, one is the top surface is all yellow, part of the top surface is yellow is the shape of a small fish, part of the top surface is a cross, part of the top surface is missing two corners, the first one is directly to the next step, the second shape is to put the yellow to the left, see if the block on the left side of the front is yellow, yes on the right reverse, on the reverse, right straight, on the reverse, right reverse, on the reverse twice, right straight, are a layer of 90 degrees, twice is 180 degrees (referred to as small fish 1), if the left is not yellow, The right side is yellow, and the above process to do the corresponding line, right to the front, front to right, forward to reverse exchange (referred to as small fish 2), the rest is to look at the left rear corner block, if it is a cross must let the left rear corner block yellow color to the left, if it is missing two corners must let the left rear corner block change the color to the back, referred to as 2 after 4 left, repeat the right reverse on the right reverse right reverse on the reverse 180 right on the line, so that it becomes a small fish shape, just do it according to the shape of the small fish.

Look at the side of the upper layer, if it is the same color of the corner blocks on both sides of the surface, first put the upper surface to the front, the right side of the corner block on both sides of the same color, and then the right 2 under the right reverse right reverse right down 2 right reverse on the right reverse right reverse steps on the line, if they are not the same, let the top face forward, first use this step to screw on the line, after screwing or so that the color of the two corner blocks on the right side is the same to get the top four corner blocks.

Then turn the front into the top, if they are not the same to do small fish 1, turn 180 degrees with the vertical line as the axis, and then do small fish 2, so that there must be a side color exactly the same, after doing it, there must be a side color exactly the same, or after doing the previous step, you must make this side face forward, if the color of the center of the top light on the right side needs to go to the back, first do small fish 1, turn 180 degrees with the vertical line as the axis, and then do small fish 2, if not, turn 90 counterclockwise with the vertical line as the axis, do small fish 2, Turn 180 degrees on the vertical line as the axis, and then make a small fish 1, and you're done, hope.

4. Set up a cross at the top, and adjust all the four top edges of the Rubik's Cube to the top surface with the same color as the top surface. At this point, there may be 4 situations: when we encounter a "point", it will be a "small turn" after the action, and then "one word", and finally a "cross".

In this way, the top cross of the third-order Rubik's Cube is turned out.

Extended information: 1. The general reduction method of the third-order Rubik's cube: layer first method, most beginners choose the layer first method, which is characterized by few formulas and easy to understand, and the general steps are as follows:

1) For the top layer of the cross, restore the top layer of the edge;

2) Restore the top layer corner block;

3) Restore the middle layer of the edges;

4) For the bottom cross, restore the bottom edge;

5) Flip the bottom corner block to align the bottom color;

6) Adjust the position of the bottom corner block to complete the restoration.

2. Advanced reduction method: CFOP method, which is the method used by most racing players, can restore the six sides of the Rubik's Cube within 30 seconds after proficiency, approximate steps:

1) Cross at the bottom layer;

2) There are 41 cases for completing the first two layers (F2L);

3) Top surface reduction (OLL);

4) Top Surface Reduction (PLL).

1. The first layer: the bottom edge is in place (also known as the bottom frame cross, the process of correct restoration of the bottom four edges) The bottom shelf of the Rubik's Cube can be self-taught, but the relative position order of the four edges to be restored in this step should be noted because we use the white center block as the bottom layer, according to our current mainstream Rubik's Cube sticker method (yellow on the bottom, white on the front, blue on the front and green on the back, orange on the left and red on the right), if we first restore the white and blue edges. 2. Then we keep the white center block at the bottom, the white and red squares should be placed on the right side of the white and blue squares, the white and orange squares are placed on the left side of the white and blue squares, and the white and green squares are placed on the opposite side of the white and blue squares.

3. Then rotate the top layer of another color (blue or red or green or orange) to make it the same color as the corresponding center block, so that we rotate it 180 degrees, and the corresponding edge will be correctly restored to the bottom. Nuclear tank.

Here's how:

1. Align the first side of the cross, and add four sides of the T-shaped shape to the first side.

2. Deal with the four ridge blocks of the second layer and align the first two layers.

3. Draw a cross on the new yellow top surface.

4. Adjust the orientation of the top layer character block and align the top layer with the yellow side.

5. Adjust the order of the top-level role blocks.

6. Adjust the order of the top layer of prism blocks to restore the Rubik's Cube.

Rubik's cube top-level reduction formula. Top cross (color) bottom left, top left, front right, top right, front left, top left.

Top Corner Block (Color) Left Hand: Top Left, Top Right, Bottom Left, Top Right, Top Left, Top 180, Bottom Left.

Rubik's Cube restores the formulaThe formula for the situation is: (Ascend, Right, Ascend, Right, Ascend, Ascend, Ascend, Ascend, Ascend, Ascend,

The formula for the situation is: (upward reversal, forward reversal, upward order, forward order, top order, right order, right direction, right direction).
