Introduction
In this step, you are going to lean how to make a Yellow Cross. You might find this step hard and difficult to understand but this step is short and you're halfway there!
What you are going to Learn
You are going to learn how to make a yellow cross. This is complicated and difficult to memorize at first. There are 3 cases of making a cross, a dot case, TEO(Two Edge Oriented) case, and a line case.
Dot case - you don't see any edges oriented.
TEO(Two Edges Oriented) case - only two edges are oriented and adjacent to each other.
Line case - two edges are oriented and opposite of each other.
Algorithm:
LINE: F (R U R' U) F'
TEO: F (R U R' U')2 F'
DOT: (F R U R' U F') U2 (F R U R' U F')
YOUR GOAL
Procedure
Begin by looking on the top layer.
Identify how much edges are oriented you neither have none oriented, 2 oriented, or 4 oriented.
If you have 2 oriented you either have the Line case or the TEO (Two Edge Oriented) case.
Line case: Position them by making a Horizontal line, not vertical, Then, perform the algorithm, F (R U R' U) F'
TEO case: Position them where one of the edge is pointing at the 12:00 and the other pointing at 9:00. Then, perform the algorithm, F (R U R' U')2 F'
If you have no edge oriented on the top layer, perform this algorithm
(F R U R' U F') U2 (F R U R' U F')
