What This Algorithm Does
This technique pairs two edge pieces that are in different layers. When one piece is in the top layer and the other is in the middle layer, you need this method to bring them together.
Recognition Guide
How to recognize this case:
- One edge piece is in the top layer
- The matching piece is in the middle layer
- They need to be brought together to form a pair
- This is more common than same-layer pairing
Method: Use wide moves to bring the pieces into the same layer, then pair them.
For Kids 👶
Sometimes the two pieces you need to pair are in different layers - one on top and one in the middle. You need to bring them together first!
The trick is to use "wide moves" - these turn two layers at once. This helps you move both pieces at the same time so you can pair them up!
Once you get them in the same layer, you can pair them just like the "same layer" method!
For Adults ⚡
When edge pieces are in different layers, you need to use wide moves (turning multiple layers) to bring them together. This is the most common edge pairing scenario on the 4×4.
Technique: Use wide U moves (Uw) to align the pieces, then use a pairing sequence to join them. The exact sequence depends on the positions of both pieces.
Common Sequence: Uw' R U R' F R' F' R Uw (varies based on piece positions)
Key Concept: Wide moves are essential for 4×4 solving. They allow you to manipulate multiple layers simultaneously, which is necessary for edge pairing.
Technique
Uw' R U R' F R' F' R Uw
Note: The exact sequence varies based on piece positions. This is a common pattern.

Common Mistakes
- Wrong wide move: Make sure you're using Uw (wide U) correctly - it turns two layers.
- Breaking pairs: Be careful not to separate already-paired edges.
- Wrong pieces: Make sure you're pairing the correct two pieces together.
- Not recognizing the case: If pieces are in the same layer, use the same-layer method instead.
