Six cases with one yellow corner, the front right yellow facing right.
Goal
The first two layers are done and the top has a yellow cross. The corners form the shape. One algorithm makes the top yellow and puts the corners in place.
How to recognize it
Only compare top corner stickers with each other. Words used here:
- Only look at : the two stickers at the ends of each side's top row. Ignore the edge sticker in the middle.
- (or left, right, back): the non-yellow top corner sticker on that side. On a side with two of them, call them front and rear (or left and right).
- : a side's two top corner stickers have the same color.
- : red and orange, green and blue. Two different colors that are not opposite are .
Put the yellow corner at the front left. Compare the left sticker with the back sticker, the right sticker and the front side's right sticker. One always matches and one is always opposite.
How to hold the cube
White on the bottom. Every case in this lesson uses the same grip, shown under the controls. The player adds a U at the start or end when needed.
The main idea
The Reverse fish mirrors the Fish. Reverse fish 1 is the Reverse fish shape from with the corners already in place, so that algorithm also solves it.
Check before moving on
The top is all yellow and each side has two matching top corners. The edges may still be off; an edge PLL fixes them.
