Line
Line: two yellow edges on the top face sit opposite each other, forming a horizontal line.
U align
Edge-flip formula
Build: line (two edges opposite in a line)
U align · line horizontal
U align
Rotate the top face so the line is horizontal (parallel to your line of sight) to set up the edge-flip formula.
Edge-flip formula · line → cross
With the line horizontal, do one edge-flip (F R U R' U' F') to complete the yellow cross.
Two yellow edges on the top face sit opposite each other, forming a horizontal line.
The two edges are opposite each other in a straight line.
Make sure the line is horizontal (parallel to your line of sight), then do the edge-flip.
This step flips the line into a cross.
Line → cross
With the line horizontal, run F R U R' U' F' once to complete the yellow cross. Progress: line → done.

Line · aligned
Line (horizontal): two yellow edges on the top face sit opposite each other in a horizontal line, already horizontal.
U align
Edge-flip formula
Build: line (already horizontal)
U align · already horizontal
Edge-flip formula · line → cross
The line is already horizontal; no U needed. Do one edge-flip (F R U R' U' F') to complete the yellow cross.
Two yellow edges on the top face sit opposite each other, forming a horizontal line.
The line is already horizontal (parallel to your line of sight).
The line is already horizontal; no U needed.
This step flips the line into a cross.
Line → cross
With the line already horizontal, run F R U R' U' F' once to complete the yellow cross. Progress: line → done.

Line · needs U
Line (needs U): two yellow edges on the top face sit opposite each other as a vertical line; do a U first to turn it into a horizontal line.
U align
Edge-flip formula
Build: vertical line (needs U to turn into a horizontal line)
U align · vertical to horizontal
U align
U-turn the vertical line into a horizontal line (parallel to your line of sight) to set up the edge-flip formula.
Edge-flip formula · line → cross
First U-turn the vertical line into a horizontal line, then do one edge-flip (F R U R' U' F') to complete the yellow cross.
Two yellow edges on the top face sit opposite each other as a vertical line.
The vertical line is perpendicular to your line of sight; do a U first to turn it horizontal.
First U-turn the vertical line into a horizontal line, then do the edge-flip.
This step flips the horizontal line into a cross (a vertical line must be U-turned horizontal first).
Line → cross
First U-turn the vertical line into a horizontal line, then run F R U R' U' F' to complete the yellow cross. Progress: vertical line → (U to horizontal) → line → done.

L-shape
L-shape: two yellow edges on the top face are adjacent, forming a right-angle L.
U align
Edge-flip formula
Build: L-shape (two edges adjacent at a right angle)
U align · L-shape to 9 o'clock
U align
U-turn the L-shape to the 9 o'clock position (one edge up, one edge left) to set up the edge-flip formula.
Edge-flip formula · L → line
With the L-shape at 9 o'clock, do one edge-flip (F R U R' U' F') to turn the L into a horizontal line.
Two yellow edges on the top face are adjacent, forming a right-angle L.
The two legs of the L are adjacent, forming a right angle.
U-turn the L-shape to 9 o'clock (one edge up, one edge left), then do the edge-flip.
This step flips the L into a horizontal line (the L must be set to 9 o'clock first).
L → line
With the L-shape at 9 o'clock, run F R U R' U' F' to turn the L into a horizontal line. Progress: L-shape → line → done.
-
L-shape · aligned
L-shape (aligned): two yellow edges on the top face form a right-angle L, already at the 9 o'clock position.
U align
Edge-flip formula
Build: L-shape (already at 9 o'clock)
U align · already aligned
Edge-flip formula · L → line
The L is already at 9 o'clock; no U needed. Do one edge-flip (F R U R' U' F') to turn the L into a horizontal line.
Two yellow edges on the top face are adjacent, forming a right-angle L.
The L is already at 9 o'clock (one edge up, one edge left).
The L is already aligned at 9 o'clock; no U needed.
This step flips the L into a horizontal line.
L → line
With the L-shape already at 9 o'clock, run F R U R' U' F' to turn the L into a horizontal line. Progress: L-shape → line → done.

L-shape · needs U
L-shape (needs U): two yellow edges on the top face form a right-angle L; do a U first to bring it to the 9 o'clock position.
U align
Edge-flip formula
Build: L-shape (needs U to 9 o'clock)
U align · L-shape to 9 o'clock
U align
U-turn the L-shape to the 9 o'clock position (one edge up, one edge left) to set up the edge-flip formula.
Edge-flip formula · L → line
First U-turn the L-shape to 9 o'clock, then do one edge-flip (F R U R' U' F') to turn the L into a horizontal line.
Two yellow edges on the top face are adjacent, forming a right-angle L.
The L isn't at 9 o'clock; U-align it first.
First U-turn the L to 9 o'clock, then do the edge-flip.
This step flips the L into a horizontal line (U-align first).
L → line
After U-turning the L-shape to 9 o'clock, run F R U R' U' F' to turn the L into a horizontal line. Progress: L-shape → (U to 9 o'clock) → line → done.

Dot
Dot: none of the four edges on the top face shows yellow up; only the center is yellow.
U align
Edge-flip formula
Build: no yellow edge on top (only the center is yellow)
U align · any orientation
U align
The dot has no orientation requirement; you can run the edge-flip formula at any angle.
Edge-flip formula · dot → L
Do one edge-flip (F R U R' U' F'); the dot becomes an L-shape (two more flips complete the cross).
None of the four edges on the top face shows yellow up; only the center is yellow.
Only a single yellow dot remains at the center; no edge around it shows yellow up.
The dot has no orientation requirement; run the formula at any angle.
This step flips the dot into an L-shape.
Dot → L
Run F R U R' U' F' to flip the edge orientations, turning the dot into an L-shape. Progress: dot → L-shape → line → done.

Done
The yellow cross is done.
U align
Edge-flip formula
Build: yellow cross done
U align · done
The yellow cross is done; move on to the top corners.
The yellow cross is done; move on to the top corners.
The yellow cross is done; move on to the top corners.
