When you reach the last layer (typically Yellow), you will encounter standard 3x3 cases alongside shape-mod anomalies. Last Layer Orientation (OLL)
Repeat until all four corners are sitting in their correct structural slots. 4.2 Orienting Corners
If centers are wrong, the edge pairing will never work. fisher cube algorithms pdf
Insert the four white corner pieces into their correct slots. These are the sharp, three-sided wedge pieces. Position the corner above its target slot.
If your puzzle is entirely solved but one rectangular side center is upside down, use this algorithm to flip it: When you reach the last layer (typically Yellow),
Hold the line horizontally, then run: F R U R' U' F' 🛑 Parity Alert: The Single Flipped Edge
Hold the cube so the broken middle-layer edge is on the slot. Insert the four white corner pieces into their correct slots
Two faces (usually Top and Bottom) remain square. The other four side centers are rectangular and dual-colored.
