The 2x2x2 cube pieces and notation
The pieces
To be able to solve the cube, we must know it a bit, and to start, we will get to know the pieces of the cube. The 2x2x2 cube has 8 pieces, and all are of the same type:
Corners
These 8 pieces that make up the cube are corners, which means that each piece has 3 different colors. All pieces have the same shape, and all have 3 colors.
2x2x2 cube notation
To be able to read and write series of moves, the notation that I will explain next is used.
The cube has 6 faces, and each face is assigned a different letter, which will mean turning the face 1/4 turn clockwise. The counterclockwise rotation is determined by placing a ' after the letter. If we need to turn a face 1/2 turn, we put a 2 after the letter.
- F: Front - Front
- U: Up - Up
- D: Down - Down
- R: Right - Right
- L: Left - Left
- B: Back - Back
The possible moves are as follows.
Clockwise:
Counterclockwise:
Double layer moves can be indicated by using the number 2 after the letter. The direction of the turn is not relevant, as whether you do it clockwise or counterclockwise, the result will be the same. Here are some examples:
