Rubix Cube Solution PART 5 POSITION AND COLOUR ALIGN ALL REMAINING OUT OF PLACE MIDDLE-EDGE PIECES

THE RUBIX CUBE SOLUTION CONTINUED

PART 5 – POSITION AND COLOUR ALIGN ALL REMAINING OUT OF PLACE MIDDLE-EDGE PIECES, CONTINUED FROM (PART 4)

New Orientation

Turn the whole cube so that the 2 solved sides appear on the left and right sides. See figure 24 below.

Keep this new orientation fixed, and turn just the centre up and away until all 4 remaining centre squares fall into correct colour alignment as in figure 24. Note: Blue on the left side.



At this point, you will find one of five things will happen:

Case 1 –Four middle-edge pieces out of place and not colour aligned. Use process (A) on the following page twice.

Case 2 – Three middle-edge pieces out of place and not colour aligned. Use process (A).

Case 3 – Four middle-edge pieces in position but not colour aligned. Use process (B) below twice.

Case 4 – Three middle-edge pieces out of place and one piece in position but not colour aligned. Use process (A) then process (B).

Case 5 – Two middle-edge pieces in position but not colour aligned. Use process (B).

A. Process A

The goal of Process (A) is to place all remaining unsolved middle-edge pieces into their correct positions.

The four step procedure outlined below will move three middle-edge sub-cubes, causing them to exchange their positions with each other, without disturbing other sub-cubes. Figure 25 shows the three side sub-cubes that will exchange positions. The position exchange occurs as follows: the side sub-cube marked 1 will move to the position occupied by side sub-cube marked 2; the side sub-cube marked 2 will move to the position marked 3; and the side sub-cube marked 3 will move to the position marked 1.



Now check all the remaining out of place middle-edge pieces and pick 3 that will fall into correct place if exchanged.

Remember; first find the 3 out of place middle-edge cubes that will fall into correct position if they are exchanged in the manner below:

Be careful to maintain the starting orientation when using the procedure, hold both solved outside thirds firmly in steps 1 and 3.







Repeat Process (A) steps 1-4 above until either the puzzle is solved OR you find you have left one pair of middle-edge pieces that are in position but not colour aligned. To solve this last pair go on and do process (B) steps 1-12 below.

If you find you are in Case 4, you will have 2 pairs of middle-edge pieces in position but not colour aligned as in figure 26A. Process (B) will solve them one pair at a times.




B. Process B

This 12 step process is known as Rubik’s Manoeuvre after Erno Rubik, the inventor of the cube.

Before you run Process (B), the 2 middle-edge pieces whose colours are to be flipped must be opposite each other on top of the cube as shown in figure 26A.

Repeat Rubik’s 12 step process if you have another pair in position that needs to be colour aligned.

Now you have solved the cube – Congratulations, you’re a CUBIST! Mix it up and start again.
