• How to Solve a 4x4x4 Rubik's Cube - Part 3...
This is a tutorial on how to pair the edges of the 4x4 to eventually convert the 4x4 into what resembles a mixed up 3x3. We will have to know how to position edges opposite from one another and with switched orientations (colors on the same face). The algorithm we will use for this step is:
(Dd) R F' U R' F (Dd)'
NOTE As mentioned in my 3x3 tutorial, whenever you are turning a face a certain direction, you must turn it (them) as if you are looking at that face(s) directly. From the perspective beneath the cube, when you perform a (Dd) move, it will be spinning in a clockwise or "right" direction and vice versa.
NOTE In my video, I was a little ambiguous/unclear on how to position the last two pairs of edge pieces before performing the above algorithm. When I said we "need the same color on the same face".. I meant to say "both identical pairs of edges should have the same color on the same face as its complementary piece and be situated in the same layer as well".. I believe that the example in the cube cleared it up, but I just wanted to put it here too in case someone actually reads all this :-)
This algorithm will be used to fix the remaining 2 pairs of edges. You may not have to even use this algorithm depending on how you match the last pairs of edges.
IF YOU FIND THIS TUTORIAL HELPFUL PLEASE COMMENT. I WOULD LIKE TO KNOW IF PEOPLE FOUND THE VIDEO HELPFUL.
