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 first 2/3 of the Cube. (For help, see past posts on Solving the Cube.)
The Ferris Wheel Move is used to move the corner pieces on the bottom to the correct address. However, it does not orient the corners.
In essence, this move swaps two adjacent corners. Thus, you should never have to do it more than 3 times to get all four corners on the bottom to the correct address.
- Identify 2 corners in the Bottom which need to switch places. Turn the cube so that the side containing both corners is facing you. We will call this front face the Ferris Wheel. Board the Ferris Wheel by turning the Right-hand side 1 turn down and then the Bottom 1 turn to the left. Return the Right-hand side to starting position by turning it up 1 turn.
- Ride the Ferris Wheel by turning the front side 1 turn clockwise.
- Unload the Ferris Wheel by turning the Bottom 1 turn to the left.
- Rewind the Ferris Wheel by turning the side 1 turn counter-clockwise.
- Solve for Y’t (Turn the Right-hand side down 1 turn. Load the White in by turning the Bottom 1 turn to the right. Bring the Right-hand side up 1 turn, thus fixing the top.)
- Finish off the move by turning the bottom 2 turns (180 degrees.)
- Look to see if all the corners are in the correct place. If not, repeat the move on other corners.
- To remember this move think: Down, Board, Ferris, Unload, Ferris back, Solve for Y’t.
Challenge: Do the Ferris Wheel move with your eyes closed.
