Step 4: Yellow cross

Youtube video starting on 13:49

Now we will solve the yellow side which was neglected until now, and need to create a yellow cross on the yellow side. The front side must be yellow. And then there are two types of patterns that might be possible.

• A horizontal yellow line. Goto step 4a.
• A two-two pattern, whereas two yellow pieces are on the right side, and two yellow pieces on the middle side. Goto step 4b.

Step 4a: The pattern is a horizontal line.

Then the pattern is a horizontal yellow line like this:

Make sure that the yellow side is on UP, and that the yellow horizontal line is really horizontal (not vertical). Then, Rotate as follows: F R U R' U' F'

Step 4b: The pattern is a two-two pattern

Then the pattern is a two-two-pattern like this.

Make sure that the yellow side is arranged so that the bottom-left piece is yellow. Then, rotate: F U R U' R' F'

Result of step 4

• The white side complete
• On all sides the top two rows are complete with the correct color
• A yellow cross on the yellow side
