The most basic Rubik s Cube term 50, the most basic Rubik s Cube term

f front

b back

R Right (right).

l Left (left).

u up (above).

d down (below).

90 degrees clockwise represents the letter "e.g. r is 90 degrees clockwise on the right".

90 degrees counterclockwise represents the letter r'It is 90 degrees counterclockwise rotation on the right

180 degrees clockwise represents the letter 2 F2L->OLL->Pllcross: It means cross (of course, the first layer of the cross is constructed).

F2L: It means first two layer

oll: It means orient last layer, which means to turn all the colors of the last layer upside down.

pll: It means position last layer, that is, all the edge and corner positions of the last layer are swapped.

How many seconds to complete is called sub.

An unfinished match is called a DNF

1. Cross the bottom cross.

2, u above.

3, d below.

4. l Left.

5. R right.

6, f front.

7, b back.

9. sub refers to the fastest recovery speed.

10. x The whole Rubik's Cube rotates in the direction of r.

11. y The whole Rubik's cube rotates in the direction of u.

12. z The whole Rubik's cube rotates in the direction of f.

13. ( 2 means that the formula in parentheses is done twice in a row.

14. U' indicates that the top is turned counterclockwise.

15. U means that the above turns clockwise.

2nd floor replication party. Complete. The first floor gave **. I won't say anything about it. Go in and see it.

1. Order: The number of blocks arranged on each side of the Rubik's cube. The 3*3*3 Rubik's cube that we usually see is called the third-order Rubik's cube.

2. Restoration: The process of restoring the Rubik's Cube from a chaotic state to a six-sided color.

3. Formula: For a certain state of the Rubik's Cube, the steps used to rotate the Rubik's Cube to achieve another target state. It is important to emphasize that memorizing formulas does not use the brain, but muscle memory.

4. POP (Pop Up Flying Edge): When turning the Rubik's Cube, there are moving blocks falling out, and the Rubik's Cube is scattered. In the current competition, players need to install the Rubik's Cube back before they can continue the game.

5. DNF (Did Not Finish Forfeit): The Rubik's Cube Restorer feels that he cannot restore the Rubik's Cube within a satisfactory time and gives up the game.

6. Sub XX (subtraction less than XX seconds): The average restoration speed of the Rubik's Cube is less than XX seconds. For example, sub30 means that the average restore time is less than 30 seconds.

The first letters of up (up), down (down), front (front), back (back), left (left) and right (right) in English represent the six sides of the Rubik's cube respectively, namely you (up), d (down), f (front), b (back), l (left), and r (right). When rotating the right layer of the Rubik's cube, if you rotate 90° clockwise from the right side, you will use r to indicate the rotation, and if you turn 90° counterclockwise, you will use r'This rotation is described, and if it is rotated 180° clockwise, it is represented by R2. In addition, the movement of the interlayer rl'It is simply written as rs (indicating that the left and right layers are rotated 90° clockwise with the right layer as the reference at the same time), and the movement of the interlayer rl is simply written as ra (i.e., the right layer rotates 90° clockwise, and the left layer rotates 90° in the opposite direction to it), and (rsfs)3 means that the RSFS action is repeated 3 times.

Order: The order refers to the number of blocks on each side of the Rubik's cube, for example, there are 3 small blocks on each side of the third-order Rubik's cube.

Restoration: refers to the process of going from a non-original state to an original state of the Rubik's Cube.

POP (Flying Edge): Refers to the situation in which some part of the Rubik's Cube is detached from the Rubik's Cube during the restoration, and if it appears in a match, it is considered an invalid recovery process.

DNF (Waiver): Did Not Finish means that the Rubik's Cube restorer feels that he cannot complete the Rubik's Cube within his or her satisfactory time and abstains, and can have a DNF in the match.
