F2L (First 2 Layers)

In the beginner method, we solved the white corners, then the middle edges. In F2L, we solve both at the same time by creating a “Pair” and inserting it into the slot.

The Logic: Split & Pair

The core skill of F2L is not memorizing algorithms. It is intuitive manipulation. You have two pieces (Corner + Edge). You want them to be stuck together correctly, then dropped into their home.

The “Splitting” Technique

Often, your pieces are stuck together incorrectly (e.g., checking board pattern). To fix this, you must “Hide the Corner”.

1. Move the corner to the bottom layer (temporarily).
2. While it’s hidden, the top layer is free to spin!
3. Move the edge piece to a better spot.
4. Bring the corner back up.

Golden Rule

Never hide a piece if it breaks a “Solved Pair” or your “Cross”. Only hide using “Empty Slots” (slots that aren’t solved yet).

The 3 Fundamental Cases

Most F2L cases reduce to one of these three scenarios.

Case 1: Easy Pair (Different Colors on Top)

The corner and edge are touching or near each other, and the top colors are different.

• Goal: Pull them together to form a block.

Case 2: Split Pair (Same Colors on Top)

The corner and edge have the same color facing up.

• Goal: You want them to be far apart on the top layer.
• Action: Hide corner -> Move edge away -> Restore corner.

Case 3: White Sticker Facing Up

The corner has white facing up. This is annoying.

• Goal: Knock the white sticker to the side.
• Action: Align edge with center -> Turn side to hide edge -> Move corner on top of edge -> Restore side.

Pro Tip: Lookahead

The secret to F2L speed isn’t turning fast. It’s never stopping. While your hands are solving Pair #1, your eyes should NOT be watching Pair #1. They should be hunting for Pair #2.

• Don’t watch what you are doing. Trust your muscle memory.
• Scan the top layer for the next Red/Blue edge while solving Orange/Green.
