EG2: Bowtie

Goal

The white face on the bottom is done and the bottom layer has two diagonal corners swapped (EG2). The top is the Bowtie shape. One algorithm solves the whole cube.

How to recognize it

First look at the bottom row of the four sides. EG2 has no side with a matching pair. Exactly one side means EG1; all four mean CLL.

Then look at the top row of the four sides, as in CLL: Bowtie. Each case has the same top layer as the CLL case with the same number. 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.

Put the yellow corners at the front right and back left, with the front left yellow facing front. Look at the back and left, then compare the front sticker with the two left stickers.

How to hold the cube

White on the bottom. Hold the top like the CLL lesson with the same shape, shown under the controls. The bottom layer can sit any way.

The player adds a U at the start or end when needed. After the algorithm, one U or D turn may be left.

The main idea

After this lesson EG is done. With CLL and PBL, you can finish from any first face, whatever the bottom layer.

Next lesson

EG is done. Practice recognition: scramble, build a white face, check the bottom layer, then name the case.
