DIRECTIONS FOR SOLVING THE 5x5x5 (Professor) CUBE
These instructions can be used to solve a 5x5x5 cube, also known as the professor cube due to its difficulty. These
directions are a graphical version of those given by Jacob Davenport. I would appreciate any and all feedback or
questions about the instructions; please see the end of this page for the e-mail address.
Purchasing Puzzles:If you are having troubles finding stores that sell cubes and similar puzzles, I have a list of on-line sitesthat may have what you're looking for.

&My directions for Solving the Rubik's Cube (3x3x3)- these also apply to the 2x2x2
See Denny's solutionfor solving the 3x3x3 cube. This is a more detailed solution for the 3x3 than the one I
provide (mirrored from the now missing http://www.calormen.com/vpm/puzzlesolutions/rubikscube/)

KEY TO SYMBOLS FOR THE MOVES
The figures in this document represent a sample
cube. Although the colors on your personal cube may
be different than the figures, I feel that the coloredfigures will still be helpful in solving the cube. I would
suggest matching as many colors on your cube as
possible to the figures, then making mental notes
about which colors correspond between your cube
The diagrams show all six sides of the cube by
pretending that mirrorsare being held up so that you
may see the "hidden" sides.
The directions for what parts of the cube to turn and
when are given in a code that is relative to the current
positioningof the cube. Each side descriptor refers to
a side with respect to the figure the move is
referenced to. This means that the front side can be a
different color, depending on the diagram being used.

See Move 1of my 3x3x3 Rubik's Cube page for
instructive diagrams to illustrate the moves.
The Letters:The side descriptors are:
Ufor the top (Upper) side,
ufor the 2nd layer down from the top (just below the upper side),
Lfor the left hand sidelfor the 2nd layer in from the left hand side
Ffor the front side
ffor the 2nd layer in from the front side
Bfor the back side
Rfor the right hand siderfor the 2nd layer in from the right hand side
Dfor the down (bottom) sidedfor the 2nd layer up from the down (bottom) side, and
Hfor the horizontal center slice (between u and d).
The Numbers:Since the lower case L: l looks like the number 1, a letter by itself means to turn the side clockwise one quarter

turn. A letter with a 2 following it means to turn the side two turns (halfway around). A letter with an apostrophe
(') means to turn the side counterclockwise one quarter turn (a -1 can be used in place of an apostrophe, but
the apostrophe takes up less space).
For example, U F2f2 D' Llmeans to rotate the upper side clockwise one quarter turn, the front side and2nd layer in from the front side clockwise twice (half way around), the down (bottom) side
counterclockwise one quarter turn, and the left side and second layer in from the left side clockwise one
quarter turn. Look directly at the specified side indicated to determine which direction is clockwise or
counterclockwise.
For the central horizontal slice H, look at the cube through the top sideto determine the clockwisedirection.
The Pieces (see the Key cube above):
The piece in the center of each side is the center piece
Next to each center is a "cross" piece since the cross pieces form a cross or + with the center piece
Diagonally from each center piece are four "point" pieces
Each side of the cube has five pieces along it: Corner, Wing, Edge, Wing, Corner
In the figures, any gray pieces represent pieces that don't matter and can be any color. To increase clarity, I have
shown a lot of colored pieces. In most cases, the figures represent an example of the situation being described,
while the colors don't have to match perfectly.
Step 1: Solve the top points and crosses

Pick a center piece to represent the
first side of the cube solved (blue inthese figures) and solve the points
and crosses on that side. One crossmay be left empty since it will beused as the "keyhole" later on.
Step 2: Solve the bottom points
Get the four green points on the down (bottom) face in place, using Move 2a and Move 2b as necessary.
2a.To move two points into position:

Orient the cube as shown in Figure2a, where the two points to bemoved into place are on the right
side of the front face while any
green points already on the downface are on the right side of thedown face, then perform Move 2a.You will need to rotate the front side and
middle horizontal slice as necessary to
place pieces into position.
Move 2a:
R'r' D2 Rr
In words, rotate the Right side and 2nd layer in from the right side counterclockwise one turn, the
down (bottom)side two turns (180 degrees) and the right side and 2nd layer in from the right sideclockwise one quarter turn.
2b.To move 1 point into position:

Orient the cube as shown in Figure
2b, where the one point to be movedinto place is on the right side of thefront face while any green points
already on the down face are on theright side of the down face, then
perform Move 2b.You will need torotate the front side and middle horizontal
slice as necessary to place pieces into
position.
Move 2b:
R'r' D Rr
Step 3: Solve the remaining 16 points (on the sides)
Solve the remaining 16 points on the four sides. Accomplish this using Dd moves (bottom two layers) along
with F (front side) moves.

First, position the top 8 points along the 4 sides:
Rotate Dd freely to get Points next to their
centers, then F to put the points up to the
upper layers, yielding Figure 3. Now useMoves 3a and 3b as needed.
3a.If the upper layer already has correctly placed points:

Move 3b:

Step 4: Complete the top and bottom crosses
Complete the Blue and Green crosses. Pretend the cube is a 3x3x3, ignoring the outside edges. Insert pieces
into the bottom via the keyhole using Move 4a. During this process, it's all right if the horizontal center pieces
move around.
When the bottom is completed, finish the top using Move 4b to get the last piece into position.

4a.To insert a piece into the bottom:
Move the piece to the right handside by rotating H (the central,
horizontal slice), then rotate the righthand side, bottom, and top until itlooks like Figure 4a. Now perform
move 4a.
Move 4a:

First complete the upper cross piece of
each side using H and F moves, giving
the cube in Figure 5.
Now use Move 5a to rotate eight of the equator pieces (swapping between opposite faces) or Move 5b to
rotate between adjacent pieces.
At times you will have the situation of having to swap only two Crosses with each other, rather than doing two
swaps at the same time. Move 5c will succeed in swapping the two pieces.
5a.To exchange the location of eight of the equator pieces (Useful for symmetrically scrambled cubes):

Move 5b:
H L2l2 H' Ll H' Ll H' L2l2H Ll H Ll
Note: In this move, "Ll" indicates capital L
and lowercase "ell"; thus "Ll" means to
turn both the left hand side and the 2nd
layer in from the left hand side one quarter
turn.
5c.If only two pieces remain to be swapped:

Move 5c:U'u' R' then Move 5b thenR Uu
Step 6: Associate wings with their appropriate edge pieces
Use Move 6 to join wings with their appropriate edge piece. When doing this move, be sure that the wing
piece at the back of the second row of the left side does not already match it's neighboring edge. If it does,
place a different wing piece on the left side so as to not mess it up.
This process will take quite some time. After you have associated a few of the wings and edges, begin to pay
attention to the movement of the piece from the back-left of the cube to the back-top of the cube, trying to align
the piece with the top back edge

the piece with the top back edge.
About 50% of the time you will get a "Parity Problem", meaning that you'll have either two or four wings left to
position. Move 6a will not work in this situation, since it moves three pieces. Instead, use Move 6dto fix the
parity problem.
Moves 6b and 6c are other useful moves for orienting pieces during this process
6a.To associate two wings with their appropriate edges (on the left side):

Use your favorite 3x3x3 solutionto solve the cube, since the edges and wings act like the single edge pieces of the
3x3x3, the corners directly correspond to the corners, and the centers, crosses, and points correspond to the center
pieces of the 3x3x3, as shown in Figure 7.
I hope you have found these directions to be clear and complete, yet concise. If these directions help you to solve the
cube, I would enjoy hearing from you.

my 5x5 cubes in a long time, due to the effort required to unscramble them. Please also e-mail if you have problems
