Make the yellow face on top with one algorithm, keeping white on the bottom.
Goal
Make the whole top yellow while the white face stays on the bottom. The corners do not need to be in place yet.
How to recognize it
The seven shapes are the same as in of the layer-by-layer method. Count the corners with yellow up, then see where the other yellows face.
How to hold the cube
White on the bottom. Each shape's grip is shown under the controls. The player adds a U at the start or end when needed.
The main idea
In Ortega the bottom is not a full layer yet. So the algorithm only has to keep white on the bottom, not the side colors.
