CLL: H and yellow top

Read more

Four H cases and two cases where the top is already yellow.

Goal

The white layer on the bottom is done. The top is the H shape. One algorithm solves the whole top layer.

How to recognize it

Only compare top-layer stickers with each other, never with the bottom layer. Words used here:

  • Front sticker (or left, right, back): the non-yellow top sticker on that side. On a side with two non-yellow stickers, call them front and rear (or left and right).
  • Matching pair: a side's two top stickers have the same color.
  • Opposite colors: red and orange, green and blue. Two different colors that are not opposite are neighboring colors.

H: put the yellow pairs on the front and back, then look at the left and right stickers. Yellow top: just count the sides with a matching pair.

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 two yellow top cases are the top-only cases of Permute both layers (PBL) in Ortega. Yellow top 1 uses the Jb perm from 3x3 PLL.
