DESCRIPTION

```       The original puzzle has 9 squares per face (size = 3).  The puzzle  was
designed  by  Erno  Rubik  and  called  the  Rubik’s  Cube.   This  has
8!*12!*3^8*2^12/12 or 4.3 * 10^19 different combinations.

The Pocket Cube has 4 squares per face (size = 2) also designed by Erno
Rubik.  This has 7!*3^6 or 3,674,160 different combinations.

Rubik’s  Revenge  has  16  squares per face (size = 4) also designed by
Erno Rubik.  This has 7!*3^6*24!*24!/(4!)^6 or 7.4  *  10^46  different
combinations.

5x5x5  Cube.   This has 8!*12!*3^7*2^10*(24!)^3/(4!)^12 or 2.83 * 10^74
different combinations.

There is also the  Magic  Domino  3x3x2  cube  which  has  (8!)^2/4  or
406,425,600 combinations.

A  physical  6x6x6 cube is possible but to my knowledge no one has been
too successful in building one.  7x7x7 is also possible, but  here  one
must  make the center most cubes smaller than the outside cubes, so the
corners do not fall off when turned.

```

FEATURES

```       Press "mouse-left" button to move a piece.  Release "mouse-left" button
on  a piece on the same face and in the same row.  The pieces will then
turn towards where the mouse button was released.

Click "mouse-center", or press "P" or "p" keys to toggle  the  practice
mode (in practice mode the record should say "practice").  This is good
for learning moves and experimenting.

Click "mouse-right", or press "Z" or "z" keys, to randomize the  puzzle
(this must be done first to set a new record).

Press "G" or "g" keys to get a saved puzzle.

Press "W" or "w" keys to save (write) a puzzle.

Press "U" or "u" keys to undo a move.

Press "R" or "r" keys to redo a move.

Press "C" or "c" keys to clear the puzzle.

Press  "S"  or  "s"  keys  to  start auto-solver.  Only works on 1x1x1,
2x2x2, and 3x3x3 cubes.

Press "O" or "o" keys to toggle the orient mode.  One has to orient the
faces  in  orient  mode,  besides  getting all the faces to be the same
color.  To do this one has to get the lines to be oriented in the  same
direction,  this only matters with center piece, if at all (i.e.  those
pieces not on a corner or edge).  This does add complexity so there are
2 sets of records.

Press "I" or "i" keys to increase the number of pieces.

Press "D" or "d" keys to decrease the number of pieces.

Press "x" key to increase the number of pieces along the x axis.

Press "X" key to decrease the number of pieces along the x axis.

Press "y" key to increase the number of pieces along the y axis.

Press "Y" key to decrease the number of pieces along the y axis.

Press "f" key to increase the number of pieces along the z axis.

Press "F" key to decrease the number of pieces along the z axis.

Press "V" or "v" keys to change the view of the cube.

Press ">" or "." keys to speed up the movement of pieces.

Press "<" or "," keys to slow down the movement of pieces.

Press "@" key to toggle the sound.

Press "Esc" key to hide program.

Press "Q", "q", or "CTRL-C" keys to kill program.

Use the key pad or arrow keys to move without the mouse.
Key pad is defined for the Rubik2d as:
/     Counterclockwise

8     Up
^
4<5>6   Left, Clockwise, Right
v
2     Down

Key  pad for Rubik3d, use must use your intuition (is this a cop out or
what?).  The key pad is defined differently depending on which side  of
the  cube  your mouse is pointing at.  One thing that stays the same is
"5" is Clockwise and "/" is Counterclockwise.

Use the control key and the left mouse button, keypad, or arrow keys to
move the whole cube.  This is not recorded as a turn.

The title is in the following format (non-motif version):
xrubik{2|3}d<dimension>:   {1|2|3|4|5|6<cubes  per  edge  on  x-
axis>x{1|2|3|4|5|6<cubes per edge on  y-axis>x{1|2|3|4|5|6<cubes
per  edge  on  z-axis>}  @ (<Number of moves>/{<Record number of
moves> <user name>|"NEVER noaccess"|"practice"}) - <Comment>
If there is no  record  of  the  current  puzzle,  it  displays  "NEVER
noaccess".

```

OPTIONS

```       -geometry {+|-}X{+|-}Y
This  option  sets  the  initial  position  of the rubik window
(resource name "geometry").

-display host:dpy
This option specifies the X server to contact.

-[no]mono
This option allows you to display the rubik window on  a  color
screen as if it were monochrome (resource name "mono").

-[no]{reverse|rv}
This option allows you to see the rubik window in reverse video
(resource name "reverseVideo").

-{foreground|fg} color
This option  specifies  the  foreground  of  the  rubik  window
(resource name "foreground").

-{background|bg} color
This  option  specifies  the  background  of  the  rubik window
(resource name "background").

-face{0|1|2|3|4|5} <color>
This option allows you to change the color of a face  (resource
name  "faceColorN").  In mono-mode, color is represented as the
first letter of the color name. On the 2-D version,  the  faces
are  ordered  top  to  bottom  and  left  to  right  on the "t"
configuration.  The  sideways  "t"  or  "+-"  configuration  is
physically  consistent with the former, so it is ordered "0, 1,
2, 3, 5, 4".  If you has two colors that begin  with  the  same
letter you should have one in uppercase and one in lowercase to
distinguish them in mono-mode. You can change the colors of the
faces  to  make  a stupid cube (i.e.  all White or in mono-mode
all "W"). Unfortunately, it will not normally  say  its  solved
when its randomized. This would be cheating.

-{border|bd} color
This  option  specifies  the  border color of the pieces in the
rubik window (resource name "borderColor").

-delay msecs
This option specifies the number of milliseconds  it  takes  to
move pieces (1-50) (resource name "delay").

-[no]sound
This  option specifies if sliding pieces should make a sound or
not (resource name "sound").

-moveSound filename
This option specifies the file for the move sound the  twisting
of the puzzle (resource name "moveSound").

-{font|fn} ontname
This option specifies the font that will be used (resource name
"font").

-view <int>
This option allows you to change  the  view  of  the  cube  for
OpenGL with choice of 4 views (resource name "int").

-sizex <int>
This option allows you to change the number of pieces on a edge
along x-axis (resource name "sizex").

-sizey <int>
This option allows you to change the number of pieces on a edge
along y-axis (resource name "sizey").

-sizez <int>
This option allows you to change the number of pieces on a edge
along z-axis (resource name "sizez").

-[no]orient
This option allows you to access the orient mode (resource name
"orient").

-[no]practice
This  option  allows  you to access the practice mode (resource
name "practice").

This option specifies the user name for  any  records  made  or
else it will get your login name (resource name "userName").

-scoreFile filename
Specify  an alternative score file (resource name "scoreFile").

-scores This option lists all the recorded scores and then exits.

-version
This option tells you what version of xrubik you have.

```

RECORDS

```       You must randomize the puzzle before a  record  is  set,  otherwise  an
assumption  of cheating is made if it is solved after a get or an auto-
solve.

```

SAVEFORMAT

```       Here is the format for the xrubik configuration, starting position, and
the movement of its pieces.  The format is not standard.  The reason is
that this is simple to produce and the standard notation is no good for
variable number of pieces.

Rubik2d with default colors, not randomized (front is face 2) :
0       R     Red
1 2 3   Y W G   Yellow, White, Green
4       O     Orange
5       B     Blue

sizex: 1-6 <the number of cubes per row along x-axis>
sizey: 1-6 <the number of cubes per row along y-axis>
sizez: 1-6 <the number of cubes per row along z-axis>
orient:  0-1  <0  false, 1 true; if 1 then lines on pieces to be
oriented>
practice: 0-1 <0 false, 1 true>
moves: 0-MAXINT <total number of moves>

startingPosition:  <2  dimensional  array  of  face  and   piece
position,  each  face  has  size1 * size2 pieces, if orient mode
then orientation number follows face number: 0 up,  1  right,  2
down, and 3 left>

This is then followed by the moves, starting from 1.
move #: <face> <position> <direction> <control>
Each turn is with respect to a face and position.
Position is 0 to size * size - 1.  Position 0 is in the upper left.
Direction is represented as 0 up, 1 right, 2 down, 3 left, 5 clockwise,
and 7 counterclockwise.
Control is represented as 0 or 1, 1 if the whole cube is moved at  once
(here  position  does  not matter), 0 if not.  The xrubik record keeper
does not count a control move as a move, but here we do.

If you have a Rubik’s Cube you can not solve (2x2x2 or 3x3x3) enter  it
in  rubik.log  file.   Have  size  =  2 or 3, orient = 0, practice = 0,
randomized = 1, and moves = 0 and the  number  representation  for  the
color  of  the  piece (usually 0=R, 1=Y, 2=W, 3=G, 4=O, 5=B).  Bring up
xrubik, hit ’g’ so it will get your configuration and then ’s’ to solve
your  cube  and  then  ’w’  to  write out the steps.  Then examine your
rubik.log file.
