Step 3 / 7
The second layer
Insert the 4 edges of the middle layer.
Goal of this step
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.
