Rubic cube solution
Nov 24, 08
Invented by Gene a few years ago after 2
months of twisting cube and observing changes.
This past summer, I worked on the cube again and remembered the basics,
but the cube colors were deteriorated plus my memory had serious gaps
Purchased new cube at WalMart few days ago
Rediscovered the solution Nov 23 after two hours of work over two days
A couple things to understand:
1. There are 8 corner pieces and they will always be corner pieces
2. There are 6 center pieces and they will never change their location
relative to the other center pieces
3. There are 12 edge pieces and they can move to any other edge piece
location
4. There are 6 sides: For ease of identification, I’ll call these T for
Top, Bot for Bottom, F for Front, Back for Back, RS for Right Side, and
LS for Left Side.
5. Notice that when a cube is solved, that each color is in a definite
position relative to the other colors: the orange is opposite the red;
the yellow is opposite the white; the blue is opposite the green. The
relationship between the colors is fixed.
6. Because of the fixed relationship between colors and location, there
is a pattern that repeats itself when the cube surfaces are moved. In
short there is order in the random appearance of the cube. My solution
came from observing this repeat pattern and then making a slight
adjustment to change the order. This allowed the correct square to
arrive at the right spot at the right time.
7. My solution lets you move the squares around the cube using the same
rotation sequence over and over. All you have to do is learn the
sequence. It’s simple to do but hard to describe in words. That’s why
there are so many words.
Here is the color layout I use to solve the puzzle:
T or Top = white
Bot or Bottom = yellow
F or Front [can be any of remaining colors]
RS and LS or Right and Left sides [can be any of remaining colors]
For example: If White is T and let’s say Blue is F, then Orange will
always be on RS, Green will always be on Back, and Red will always be
on LS.
Steps:
A. My solution assumes White is always on
top and therefore Yellow is on bottom – sides can be any of remaining
colors.
B. In my solution, there are two basic
movements: movement a. and movement b.; each movement is repeated over
and over until the pieces align.
C. First let’s look at the cube: Hold
cube upright with the center White on top. Next, you want to look at the Front of
cube. As you face the Front, you can see there are three vertical rows
(left vertical, middle vertical, and right vertical) and three
horizontal rows (top horizontal, middle horizontal and bottom
horizontal). The diagonals are ignored since the cube can not rotate
diagonally.
D. Before describing the steps: My
solution begins by assuming you can get all the White squares in place
so that the top of the cube is finished, and all pieces on top are White. It will take time to figure
out the several techniques needed to align the pieces. Only the top is
finished at this point. If the top is done, then it means that the top
horizontal row is correct around all four sides of cube. Once finished,
the top horizontal row does not need to be rotated again to achieve the
solution. Remember, this is just the top horizontal row while the rest
of the cube still appears in random order.
E. Moving forward: After the top is
finished, each step that follows requires eight rotations that are
repeated exactly the same each time. Each rotation is a quarter turn
except in two cases where the rotation is a full half turn. What is a
quarter turn? Let’s face the front of the cube. Remember the White is
on top. Look at the far right vertical row
F. us to move the far right vertical row.
Each step requires the far right vertical row to be moved. Therefore it
is necessary to place both hands correctly: We want to hold the cube
with the left hand and use the right hand to move the far right
vertical row.
G. Each time we , we will do the exact
same movement: Using your right hand
H. What is basic the movement? Hold
square in left hand,
1. There are two basic sets of movement:
2. all
3. Complete the top so all White squares
are in place including corners
4. The next objective is to align the
bottom corners using
