How to Solve the Rubiks Cube - Step Four
This post will guide you through the Step Four in How to Solve the Rubiks Cube.
If you are here after reading the Step Three then please read along. Else CLICK HERE to goto Step One.
Assuming you mastered Step Three, you should now be able to make the Yellow top. Now your cube should look something like this:
Now let's move on to the next and final step on How to Solve the Rubiks Cube.
STEP 4: Permutation of Last Layer
Your goal in this step is to solve the Third Layer. So after this step, your cube should look something like this.
I've broken down this step into 2 phases.
Phase 1: The Yellow Corners
If you already have the yellow corners solved on your cube then you can skip this phase and move to phase 2. Now while holding your cube with Yellow on top and White at the bottom, rotate the top (U) layer and see if any 2 front facing corners on the top layer in the Front face are same. If you find such case, then match it with the respective color by rotating the top (U) layer. We'll call that Solved Side. Now by keeping the solved side at the Back face, Yellow on top and White at the bottom, apply the algorithm below.
Ri F Ri B B R Fi Ri B B R R Ui
If you can't find 2 matching front facing corner in the top layer, then don't worry, just apply the above algorithm once by keeping Yellow as top and White as bottom, and you should be able to find 2 matching front facing corner in the top layer after that.
Phase 2: The Yellow Edges
Case 1: If 1 edge piece is correct and 3 edges are incorrect orient the cube so that the face with the correct edge is the back (B) face. Then, determine if the edge pieces need to move clockwise or counter-clockwise and do the correct sequence below.
Case 2: If all 4 edges are incorrect, then do either sequence below once, and then determine what direction the three edge pieces need to move and do the correct sequence below. To cycle E F G Clockwise or E F G H Clockwise
F F U L Ri F F Li R U F F
To cycle E F G Counter-Clockwise or E F G H Counter-Clockwise
s F F Ui L Ri F F Li R Ui F F
If you have carefully followed the above steps, you should be able to solve the Yellow Layer. If you have done so, then you have learnt to solve the cube.
However, if you are facing any difficulty, you can refer to my video tutorial which covers the same thing.
Congratulations! :D you have learnt to solve the Rubiks Cube.
