If you have an "L" shape or a "Line" that won't resolve into a cross, one of your is flipped in place. Algorithm: (R U R' U') F' U F
You may encounter a "parity" where only one edge is flipped, which is impossible on a standard 3x3 . CENTER ADJUSTMENTS • Rotate U Center 180°: (R

If a single-color edge is technically inserted backward, you will not notice visually. However, this hidden mistake will cause a parity error on the final layer (an impossible configuration on a normal 3x3). If your top layer acts strangely in the next steps, you will need to return here and flip one of these edges. Step 3: Solving the Top Layer (OLL & PLL) and reinserts it properly).
Now, match the yellow edge triangles with their corresponding side center colors. Rotate the top layer ( ) to see how many edges line up with the side centers. If two adjacent edges are correct, hold them in the Back ( ) and Left ( ) positions. Execute the to permute the remaining edges: R U R′ U R U2 R′R U R prime U R U2 R prime

(R U R' U') F' U F + U' + (U R U' R' U' F' U F) (This kicks out the middle edge, rotates it, and reinserts it properly).
