COLL: T

Goal

The first two layers are done and the top has a yellow cross. The corners form the T 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 corner stickers: the two stickers at the ends of each side's top row. Ignore the edge sticker in the middle.
• Front sticker (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).
• Matching pair: a side's two top corner 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 two yellow corners on the left. Look at the two left stickers and the two right stickers: a matching pair, opposite or neighboring colors.

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

T 3 is the T shape from 2-look OLL: corners 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.
