Rubiks^3 Cube Workshop
About and History
3D mechanical puzzle Invented in 1974 Invented by Hungarian sculptor and
professor of architecture Erno Rubik It was then known as Magic Cube
Types of Rubik's Cube
Pyraminx 4 X 4 Rubik's cube
2 X 2 Rubik's cube 5 X 5 Rubik's
cube
3 X 3 Rubik's cube
Types of Methods
Layer Method Eoline Method Fridrich Method Petrus Method Tripod Method ZZ Method
Getting Started
Concepts and Fundas Notations Layer Method
First Layer Half Cross Full Cross Aligning Edges
Second Layer Top Face
Top Cross Top Fish Formation
Third Layer Snake-eyes We are DONE !!!
Conclusion
Concepts and Fundas
Types of pieces Corner Pieces Center Pieces Edge Pieces
8 Corner Pieces
6 Center Pieces12 Edge Pieces
Notations
R and R’ [Rotate right clockwise and anti-clockwise]
L and L’ [Rotate left clockwise and anti-clockwise]
F and F’ [Rotate front clockwise and anti-clockwise]
B and B’ [Rotate back clockwise and anti-clockwise]
U and U’ [Rotate up clockwise and anti-clockwise]
D and D’ [Rotate down clockwise and anticlockwise]
R2 or L2 or X2 [Rotate X twice]
Step 1a : Half Cross
Keep Center Yellow and make White Half Cross as shown below:
Step 1b : Full Cross
Align the color of each white edge piece with its center
Rotate face side 1800 to get full white cross
Step 1c : Aligning Edges
Select proper corner using the following algorithm: Away Down Back Up
Final Result:
Step 2 : Second Layer
Follow the same algo as in Step 1c and continue till you get complete second layer
Final Result:
Step 3a : Top Cross
After Step 2, you should get one of the following 4 cases :
Case 1 Case 4Case 3Case 2
Step 3a : Top Cross Contd.
Our aim is to achieve Case 4 from any of the other cases Algorithm to be used : F R U R’ U’ F’
Final Result :
Step 3b : Top Fish Formation
After After Step 3a, you should get one of the following 4 cases :
Hold the cube as shown ONLY and perform following to complete the top yellow layer: Algorithm : R U R’ U R U2 R’
Case 1 Case 4Case 3Case 2
Step 4a : Snake eyes
Move the completed yellow layer till you get a formation as follows:
Keep the snake-eye side behind and perform: Algorithm : R’ F R’ B2 R F’ R’ B2 R2
Step 4b : We are done
Keep the snake-eye side behind and perform the following: Algorithm :
The U or U’ will depend upon the orientation of snake-eyes.
F2 U R’ L F
2 R L’ U F2
