Find the penultimate step of the Rubik s Cube formula with Li

The formula for the penultimate step is u' r u'u' r' u' r u' r'

Specific steps:

Step 1: The bottom edge is returned to the position (also known as the bottom cross, the process of correct restoration of the bottom four edges).

Step 2: Return to the bottom corner (restore the four corner blocks of the first layer of the Rubik's Cube).

Equation 2-1: (r u r'）。

Equation 2-2: (f.)'u'f）。

Step 3: Return to the middle edge (the step of restoring the four edges in the middle layer of the Rubik's cube).

Equation 3-1: (u' f' u f ）（u r u' r'）。

Equation 3-2 :(u r u' r'）（u' f' u f）。

Step 4: Top edge position (also known as the top layer cross, the top color of the top four edges is the same as the color of the top center block).

Equation 4: f (r u r' u'）f'。

Step 5: Top Corner Face Position (the step in which the top surface color of the four top corners of the Rubik's Cube is adjusted to the top surface).

Equation 5-1:r' u2 r u r' u r。

Equation 5-2: u' r u'u' r' u' r u' r'。

Step 6: Corner homing (the other two sides of the four vertex corners of the face are the same color as the center block of the corresponding face).

Equation 6: r b' r f2 r' b r f2 r2。

Step 7: Apical edge homing (the color of the other side of the four vertex edges that have been placed is the same color as the color of the center block of the other four faces).

Assemble the four corner blocks of the third layer to make them consistent with the four sides, using a formula:

t6： l f'l b2 l' fl b2l2

When using this formula, it is necessary to ensure that the color of the two corner blocks on the B side should be consistent, if you can't find it, it doesn't matter, you can find that side by doing T6 casually.

Note: Before doing this, make sure that the two corners of the "back" are the same color, and the "left side of the Rubik's Cube" is rotated in a clockwise direction. You can see a distinct cue color:

At this time, the top surface is adjusted again, and the four corners of the top surface are the same as the second floor, okay, almost the last step of the completion of the Rubik's Cube Building.

Your [Corner Block] hasn't [Homed] yet, and it's still too early for the [Countdown Step]! (At this time, it should be the penultimate step: corner block homing) (After this step, the color of the top block will be disrupted but will not affect the color of the top edge block, so that the top corner block will be homed. ）

The regular gameplay of the Rubik's Cube is usually six steps: 1) the bottom layer of the match, 2) the second layer of the match, 3) the top layer of the cross, 4) the corner block homing, 5) the top face of the color, and 6) the side block homing.

Step 1: The bottom edge is in place (also known as the bottom frame cross, the process of the correct restoration of the four edges at the bottom layer) The second step: the bottom corner is in place (the four corners of the first layer of the Rubik's Cube are restored):

Equation 2-1: (r u r'）

Equation 2-2: (f.)'u'f）

Step 3: Return to the middle edge (the step of restoring the four edges in the middle layer of the Rubik's cube).

Equation 3-1: (u' f' u f ）（u r u' r'Equation 3-2 :(u r u' r'）（u' f'u f) Step 4:

The top edge position (also known as the top shelf cross, the top surface color of the top four edges is the same as the color of the top center block):

Equation 4: f (r u r' u'）f'

Step 5: Top Corner Face Position (the step in which the top surface color of the four top corners of the Rubik's Cube is adjusted to the top surface).

Equation 5-1:r' u2 r u r'u r formula 5-2: u' r u'u' r' u' r u' r'

Step 6: Corner homing (the other two sides of the four vertex corners of the face are the same color as the center block of the corresponding face).

Equation 6: r b' r f2 r'B r F2 R2 Step 7: Apex Alignment (the color of the other side of the four vertex ridges that have been placed is the same color as the color of the center block of the other four faces): I believe you will succeed, come on.

The formula for the sequential reduction of the third-order Rubik's cube is r'uf'u'、r'd'rdx,3or5,rur',(rur'u'),rur'u')3,u'l'ulufu'f',uru'r'u'f'uf,f(rur'u')f'，(rur'u'2 and (rur'u')5,r2d2r'u'rd2r'ur'，ru',l'u'lu2ru'r',u'l'ul。

The third-order Rubik's Cube is a 6-sided cube made of elastic hard plastic, with an axis at its core, and consists of 26 small cubes. There are 6 of them, including the center square, which are fixed and only one side is colored. There are 8 corner squares (3 colored sides) that can be rotated.

12 edge squares (edges) (2 colored sides) can also be rotated.

The third-order Rubik's cube has six faces, and the face facing itself is called "front", left = l (left), right = r (right) expression: f (90 degrees clockwise before the pin of Wu Zao), r'(right rock type 90 degrees counterclockwise), u2 (upper 180 degrees clockwise).

Rubik's Cube, together with Huarong Dao and Independent Diamond Chess, is known as the three-chambered game in the intellectual game industry by foreign intelligence experts, which is incredible. The Rubik's Cube has a variety of ways to play, such as racing, blind twisting, and single twisting, and its popularity has not diminished to this day, and it is one of the most popular intellectual games in the world with large and small events held every year.
