Note: For our purposes, we will call the White side the top and the Yellow the bottom. I will refer to the horizontal planes from top to bottom as the Top, Horizontal Middle, and Bottom. The vertical layers will be called the Right-hand, Left-hand, and the Vertical Middle.
Pre-requisite: Solve the top of the Cube. (For help, see past posts on Solving the Cube.)
If you have solved the white side, you have already solved the first third of the cube. I am going to explain how to solve the middle horizontal layer in this post: the second third.
- Locate a middle edge piece that belongs in the middle horizontal layer. (Hint: The middle edge piece will not be Yellow.) If the middle is in the bottom layer continue with this step. If not, continue to step 2. Look at the color that is facing down on the middle edge piece. Rotate the bottom so that the middle is opposite the side that is the same color. For example, if you have a red and green middle piece with the red facing down, rotate the bottom so that the middle piece is opposite the red side. Find the middle piece’s address. Hold the cube with the side containing the address facing you and the color side and the side containing the middle on the left and right.
Turn the color side down 1 turn. Turn the Bottom toward the color side 1 turn. Turn the color side up 1 turn. Turn the Bottom toward the color side again 1 turn. Turn the color side down 1 turn again. Turn the Bottom 2 turns (180 degrees). Now Solve for Y’t to fix the top (in this case White.) To remember this move think: Down, Toward, Up, Toward, Down, Toward-Toward, Up, Solve for Y’t.
- To get a middle edge piece out of the middle horizontal layer use the move described in Step 1. Be sure that the piece you want to move is facing you. Note that this piece should be part of the color side when you do the move. Down, Toward, Up, Toward, Down, Toward-Toward, Up, Solve for Y’t.
