The Rubik's Cube appeared in the 1980s and immediately gained immense popularity. The record time to complete a cube is 9.86 seconds. The minimum number of assembly moves is 26. There is more than one way to solve a puzzle in the world. By acquiring the necessary knowledge and skills in the process of assembling a cube according to a ready-made algorithm, you may come up with your own method.
Instructions
Step 1
Place the cube with either side facing you. The front side is called frontal (F). The right (R), left (L), lower (H) and back (W) sides are distinguished relative to it.
Turns are indicated by: () - clockwise quarter turn, (') - counterclockwise quarter turn, ( ) - half turn in any direction. For example, Ф' - counterclockwise quarter turn of the front side.
The center of each side is called the midpoint. A part that has two faces - a side. It is named after the names of the parties. For example, a sidewall of a VP - a sidewall of the face of which are located on the upper and right sides.
The part of a cube that has three faces is called an angle and is also named by the names of the sides. For example, the angle of the PDF is the angle of the face of which lies on the front, right and top sides.
Step 2
Choose a color for the bottom side.
Step 3
Assemble a "cross" of the same color on the bottom side of the cube so that the middle F and the edge of the side of the NP on P match in color. The middle of P and the side of the NF on F must also be of the same shade.
Step 4
Match the middle F, P, L and Z to match the color of the sides, respectively, NF, NP, NL and NZ. To do this, make the following turns: Ф "; В, В 'or В"; P "; V; F". If, after the last turn, one of the sides is raised, go to the previous step.
Step 5
Assemble the base of the cube. Here are the options:
1. The edge of the FPV angle of the same color as the middle of F is located on B, the edge of the FPV angle is on P in the color of the middle of P. In this case, perform F ', B', F.
2. The edge of the PDF angle of the same color as the middle of P is located on В, the colors of the middle Ф and the angle of PDFs on Ф coincide. Do P, V, P '.
3. The edge of the FPV angle of the same color as the middle of F is on P, the edge of the FPV angle of the middle of P is on F. Then do P, V ', P', V , P, V, P '.
If you need to "take out" a corner from the base of the cube, do F ', B', F, or P, V, P ', or P, V', P '.
Step 6
Collect the middle row of the cube. Possible options:
1. The edge of the side of the VP on R is the same color with the base of P. The color of the second edge of the side is the same as the color of the base F. In this case, do V 'F' V F V P V 'P'.
2. The colors of the base Ф and the edges of the WF sidewall on F coincide, the color of the other side of the WF sidewall is the same as at the base of P. Make B, P, B ', P', V ', F', V, F.
3. The color of the edge of the side of the FP on F is the same as that of the middle of P. Another edge of the same color as the middle of F. Perform P, V ', P', V ', F', V, F, V ', P, V ', P', V ', F', V, F.
Step 7
Place the side panels B on the corresponding sides. Here you need to place each side on its side. How it is rotated does not matter.
In order to move the side of the VF to the place of the side of the VP, perform V, L ', V , L, V, L', V, L.
Step 8
Expand the sides of the upper base and get a cross of the same color.
To do this, position the cube so that the side B, which you want to unfold, takes the position of the side FV. Do F, V, N ', L, V, N, Z, V, N, P, V, N'.
Step 9
Place the corners in the appropriate places. To move do P ', F', L ', F, P, F', L, F.
Step 10
Rotate all the corners so that all the edges of the puzzle are the same color.
To do this, position the cube so that the angle to be rotated turns out to be the angle of the FVP. Perform P, F ', P', F, P, F ', P', F.
The angle will rotate, but the cube itself will become entangled.
Leave the front the same side. Place the next corner to be rotated in place of the FVP corner. Repeat the steps.
When you match all the corners B, the edges of the cube are collected by color.
