Rubix Cube Solution PART 1(B,C) SOLVE TOP CORRECTLY

THE RUBIX CUBE SOLUTION CONTINUED

PART 1 SOLVE THE TOP CORRECTLY CONTINUED FROM (SECTION A)

Section B. Solving the four blue middle edge pieces.

The correct top middle-edge pieces will be found in one of three places: on top, either in position or out of position; on the middle row or on the bottom row.

a. To bring up a middle-edge piece from the middle row as shown in figure 9; read the note below.



Note: Before you do steps 1-4, keep the blue reference colour on top, and turn the whole cube until an out of place top middle-edge piece appears in position No.2 above. Then move the middle row horizontally until the piece you need falls into position No. 1. This is the correct starting position for the process. Now proceed to do steps 1-4.





Note: Proceed to step 4 only if the missing top middle-edge piece falls into correct colour alignment as shown in step 3 diagram above. If piece is out of colour alignment, proceed to do steps 4a-4d below.



Steps 4a-4d






b. To bring up an out of place top middle-edge piece from the bottom row, first move the piece you need directly below where it belongs as in figure 10, then follow steps 1-4 below:



steps 1-4






c. You may find an out of place top middle-edge piece with the blue reference colour hidden on the bottom of the cube. Turn just the bottom row until this piece is lined up directly below where it belongs. See figure 11, then follow steps 1-3 below.



steps 1-3





d. You will sometimes find the top middle edge pieces that are already on top but must be exchanged in order to fall into correct colour alignment. See figure 12.



To exchange the two top middle edge pieces shown in figure 12 follow steps 1-6 below. Note: x’ed pieces on step 1 are the ones that will be exchanged. Keep blue on top.









e. To exchange 2 top middle-edge pieces that face each other on top of the cube as shown in figure 13, keep blue on top and follow steps 1-3 below.



steps 1-3





If you practice solving one side correctly, you should eventually be able to put all 9 pieces of any colour into correct colour alignment in less than one minute. The more you practice the less you have to depend on the diagrams.

Section C. The starting position defined.

To begin solving the whole puzzle, first solve the blue side correctly, but leave one of its middle-edge pieces unsolved. This is known as the STARTING POSITION. (see figure 14) The missing piece will act as a guide in part 4.



Note: Except for the blue reference colour, we won’t refer to specific colours, since they don’t matter, and each cube may be labelled differently.

Now that you have solved one side of the cube correctly, you have solved one third of it. At this point you are in the STARTING POSITION and you are ready to proceed to Part 2 since you have 4 of the corner sub-cubes in correct position and colour aligned on the solved side.
