How to restore the six sides of Rubik s Cube

 

01 

 it's not difficult to find any color and directly restore it to a complete face. 

 

 02 

 the restoration of the bottom layer and the center block on the four sides takes the complete surface restored in the first step as the bottom, and restores the trapezoid formed by the bottom layer and the center block on the four sides, as shown in the figure below. At the same time as the second step is completed, the side completed in the first step best rubik's cube  remains intact. (there is no formula for the above two steps, so if you want to complete the Rubik's cube restoration, the above two steps are the most basic, and you need to explore and practice by yourself.) 

 

 03 

 explain the pithy formula first. The "plus" and "minus" in the pithy formula refer to "clockwise" and "counterclockwise" respectively. The complete face of the first step is always the bottom face, and the face facing itself is the front face. The lower two layers of the four sides are complete, which means that the lower two layers of the four sides are complete, as shown in the figure below. The pithy formula is: (the moving block is the middle block on the upper side, according to the color of the side, judge whether it is moving to the left or right of the middle side.) 1. The middle left block is up minus, left minus, up plus, left plus, up plus, up minus, up minus; 2. The middle right block is up plus, right plus, up minus, right minus, up minus, up minus, up plus, up plus, up plus. 

 

 04 

 restore the top cross. After the third step, the top cross is restored, as shown in the figure below. The formula is: front plus, right plus, top plus, right minus, top minus, front minus. 

 

 05 

 four side top middle square (cross homing) four side top middle square, that is, the middle square and middle square of the top layer of the four sidesThe layer corresponds to the central block. As shown in the figure below. The pithy formula is: Condition: find the only face on the four sides, and take this face as the "front", others can't. (if there are two sides that can face each other, you can use the following formula once to achieve the condition of using the formula.) add right, add up, subtract right, add up, add right, add up 180 degrees, subtract right. 

 

 06 

 four sides top two sides square alignment (upper corner homing) four sides top two sides square alignment, refers to the four sides top two corners square homing, homing does not mean the color should be up, as long as the color of this piece corresponds to the color of the three sides, as shown in the figure below. The formula is: Condition: find a contraposition angle on the top right of the "front" surface. (if you can't find the contrapuntal angle, you can use a formula to see the contrapuntal angle.) add, right add, up subtract, left subtract, add, right subtract, up subtract, left add. 

 

 07 

 top level completion top level completion refers to the color matching of each side of the top four corners in the sixth step, as shown in the figure below. The pithy formula is: right minus, bottom minus, right plus, bottom plus, right minus, left minus, right plus, bottom plus (use this pithy formula repeatedly, every pair of upper corners is to use "top plus" once and then complete the next corner.)
