Step4

Solve - Top Yellow Cross

Prerequisite:
  • A Rubik's cube with bottom and middle layers completed.
Outcome:
  • A Rubik's cube with bottom and middle layer completed.
  • Also a yellow cross on top layer of the Rubik's cube.

Before start solving this step, we need to check the state of the Rubik's cube.
  • Case1: Top yellow face has yellow colour piece only at the center of top face.
  • Case2: Top yellow face has yellow horizontal line on top face middle layer.
  • Case3: Top yellow face has yellow colour pieces with reverse "L".
  • Case4: Top yellow face has yellow cross.
Steps to be followed to solve "Top Yellow Cross"
We need to perform different moves based on the state of Rubik's cube as discussed below.
If Case1: Hold the Rubik's cube with yellow on top face.
Then perform the algorithm which should give you a yellow horizontal line on top face of the cube as shown in the diagram below.
F, T, R, Ti, Ri, Fi
Now hold the Rubik's cube with yellow horizontal line on top face middle layer of the cube.
Then perform the algorithm again which should give you a reverse "L" on yellow top face of the cube as shown in the diagram below.
F, T, R, Ti, Ri, Fi
Now Hold the Rubik's cube such that the top yellow face shows a reverse "L" shape.
Then perform the algorithm the last time which should give you a yellow cross on top face of the cube.
F, T, R, Ti, Ri, Fi
If Case2: As you already have a yellow horizontal line on top face middle layer of the cube.
Hold the Rubik's cube with yellow horizontal line on top face middle layer of the cube.
Then perform the algorithm again which should give you a reverse "L" on yellow top face of the cube as shown in the diagram below.
F, T, R, Ti, Ri, Fi
Now Hold the Rubik's cube such that the top yellow face shows a reverse "L" shape.
Then perform the algorithm the last time which should give you a yellow cross on top face of the cube.
F, T, R, Ti, Ri, Fi
If Case3: As you already have a reverse "L" on yellow top face of the cube.
Hold the Rubik's cube such that the top yellow face shows a reverse "L" shape. Then perform the algorithm only once which should give you a yellow cross on top face of the cube.
F, T, R, Ti, Ri, Fi
If Case4: As you already have a yellow cross on top yellow face, you can skip this step and go to Step5.
