Step 1: draw a cross on one surface to ensure that the central color blocks of the four surfaces corresponding to the cross are consistent with the cross;

Align the four corners and stand upside down to make it inverted T-shaped;

Step 2: spell the second layer and use two formulas;

T 1 is used to move the edge block of the front directly to the right of the front, and T2 is used to move the edge block of the right directly to the right.

T 1: face+face+face+face+face-face-face-

T 1: F+U+F+U+F+U-F-U-F-

T2: Right-Right-Right-Right+Right+Up+Right+

T2: R-U-R-U-

R-

U+R+

U+R+

Step 3: Use the formula to draw a cross at the project level:

T3: Right-Up-Front-Up+Front+Right+

T3: R-U-F-

U+F+R+

(Among them, look for three signs: center point, L shape and straight line)

If there is only one center point, press T3 to get an L-shape consisting of three blocks, turn it to the upper left corner to become an "anti-L-shape", then do T3 to get a font, put the words vertically, and then do T3 to get a top-level cross.

Step 4: Use two formulas to spell out the upper surface of the third layer:

T4:R-U-

R+U-

R-(U-)2

R+

T5: F+U+

F-U+

fluorion

F-

For formula T5

Use T4 formula.

When there are three variegated corner blocks on the top floor, T4 or T5 is used. The side corner blocks of the third layer (the same color as the top layer) are T4 when they are arranged counterclockwise and T5 when they are arranged clockwise. Before use, make sure that the corner block in the top left corner is the correct color block.

Supplement:

T4 and T5 are used when you spell the cross on the top of the three buildings, in order to get the correct situation of "a cross" and "a corner block".

Because the third cross has been put together, the top surface may have the following conditions:

There are no horns and crosses of the same color;

There is an angle the same color as the cross (as we expected);

There are two horns the same color as the cross.

There can't be three horns the same color as the cross.

When there is no corner block with the same color as the cross on the top surface, find a corner block with the same color as the cross on the third floor side and turn it to the upper left corner so that the color block with the same color as the top surface faces left.

When T4 is used once, there will be a color block on the top surface (what we expect).

When there are two corner blocks with the same color as the cross on the top surface, find a corner block with the same color as the cross on the third floor, or turn to the upper left corner so that the color block with the same color as the top surface faces backwards.

If T4 is used again, there will be a color block on the surface of the article (as we expect).

When there are three corner blocks with variegated colors on it (that is, there is a corner block with the same color as the cross), T4 and T5 can be used below.

Step five:

Spell the four corners of the third floor to make them consistent with the four sides, using a formula:

T6: Left+Right-

L+B2L -F+

L+B2

L2

When using this formula, make sure that the two corners on the back, that is, the color of the B side, are the same. If you can't find it, it doesn't matter. Just do T6 once, and you can find that surface.

Note: Before doing this step, make sure that the two corners of the "back" are the same color. L+ means "the left side of the Rubik's Cube" and F- means "the front side of the Rubik's Cube", that is, the side near you, turn to your left. You can see an obvious prompt color:

Let's complete this process completely:

L+, the word "one" on the left side of the top surface is downward (facing your side);

F-, "turn one word" (that is, the words standing vertically on the left side of your face become horizontal and go down);

L+, now look at the surface of the item, and there is a word "one" on the left;

B2, an inverted L shape appears on the top surface;

Now look at the face you are facing. After being L-, the word "one word" appears under the face facing you.

F+, "one word" turn, turn left from bottom;

L+, restore the "inverted L", that is, the "inverted L" on the top surface returns to the top surface.

B2, the inverted "L" on the top surface disappeared, and the word "vertical" appeared on the left side of the top surface.

L2, "the left side of the Rubik's Cube" turns to 180'c, and the top surface is restored.

At this time, adjust the top surface again, and the four corners of the top surface are consistent with the second floor. Well, it's almost the last step in the completion of the Rubik's cube building. ....

Some friends don't quite understand, so I spent so much time here. The text description is too messy for everyone to read clearly.

Step 6: The last step,

To adjust the position of the top side block to return it to its original position, we use the three-cycle method, that is, the left side, the front side and the right side. The top block on three sides moves clockwise or counterclockwise, while the back (side B) does not move. Formula:

T7: (Turn counterclockwise)

R+U-

R+U+

R+U+

R+U-

R -U-

R2

T8: (Turn clockwise)

U+R+
