Step 3 / 7
The second layer
Insert the 4 edges of the middle layer.
Goal of this step
Custom colors are on: pieces are not greyed out. Change
The 3D cube could not be loaded.
Together, the first two layers are called “F2L” (First Two Layers). All that’s left is placing the 4 middle edges.
How to: find an edge on the top layer with no yellow. Turn U until its front color lines up with the front center (it forms an upside-down “T”). Then look at its top color: if it matches the right center, the edge goes right; if it matches the left center, it goes left. If needed, turn the whole cube (yellow on top) to bring that edge to the front: the algorithms below are always done with the edge in front of you.

Tips
- The edges to insert have no yellow. An edge with yellow belongs to the last layer: ignore it for now.
- If an edge is already in the middle layer but in the wrong spot, insert any edge in its place to pop it out.
