       Xbl is  a  game  involving  dropping  blocks  like  Xtetris  but  in  3
       dimensions.   As  they  drop you can move them with numeric key pad (if
       you have), cursor key or rotate other 3 axis in 2 directions  (6  other
       keys).   Space key for dropping quickly and ’p’ key for pause.  All the
       possible keys are displayed in menu window.

       Points are scored for each block that comes to rest  on  the  gradually
       building  up  pile  of  blocks.   When  the pile reaches the top of the
       screen and no further blocks can be dropped the game ends. When a stage
       of  blocks  across  the  3D  matrix is completely filled, that stage is
       removed and all the blocks above are dropped down.  As more stages  are
       deleted the blocks fall faster.

       There is one high score table by size of matrix and pieces types.

       For your information, another 3D tetris exists, its name is spatial.  A
       sphere packing game also exists; its name is spheral.   For  these  two
       games,  contact  Andrew  Plotkin  (  )  or you can
       retrieve the file threedee.tar.Z somewhere in the world...

       An enhanced HTML version of this manual is in our computer (in the same
       directory  than  scores).   If  you  can’t  find  it, use the networked


       The next options can only be set when the game starts.

       -display hostname:0.0
              Gives the display name.

       -geometry geometry_string

       -scoregeometry geometry_string

       -zoogeometry geometry_string

       -menugeometry geometry_string
              Gives the geometry of the play, score, zoo and menu window.

       -help  Displays the options, possible values and current values.

              Displays various things for debugging.

              Creates its own colormap even if unnecessary.

              On screen with multiple visual, it search the best one  to  use.
              In this case it does not use the default visual.

       -bw    Displays in black and white even on color display.

       -buffer 0...5
              Chooses  the  buffering  method for animation.  Each method uses
              resources.  Speed of buffering  method  is  hardware  dependent.
              Perfect methods are 2,1 and 3, choose the fast one.

       -font font_name
              Chooses font for menus, score window...

       -bigfont font_name
              Chooses a big font for menu (the score and high score)

       -buttonheight -1...16
              The  height  of  3D  buttons.  If your display is slow use small
              button.  The -1 choice is half the height of the font.

       -color 0...6
              Background color for menu window.

       -sync  Uses X Synchronise. Only for debugging.

       -clearline 0...1
              If 0, clears line with rectangle filling; otherwise with a black
              line.   It’s useful with some X servers that don’t draw the same
              segment with the same  pixels.  Another  method  to  avoid  this
              problem  is  to  use a linewidth equal to 1, though in this case
              drawing is slower.

       -linewidth 0...16
              Thickness of the moving block lines.

       -fps 1...100
              Number of frames by second.  If it is set too high, the  display
              might be jumpy.  If set to 0, the game runs at maximum speed.

       -time_to_demo 1...999
              Number of seconds before the automatic demonstration.

              This option helps you to find the fastest buffering mode.

       -stat  Statistics  on launched blocks, they are displayed at the end of
              the game.

       -keytable keys_list
              A 19 characters list in the order (D=Down L=Left R=Right U=Up) :
              Rotations:   RX+,RX-,RY+,RY-,RZ+,RZ-
              Others:         LaunchBloc   CancelGame   SuspendGame   QuitGame
              Don’t forgot ’ if there are special characters.

       Next options can be changed while game is running.

       -keyboard 0...5
              This switch chooses keyboard type :
              0:Use key table, given by -keytable
              SPATIAL is the set of keys of the other 3D tetris : spatial

       -zoo   Displays the zoo (all possible pieces) when game starts.

       -score Displays the score table when game starts.

       -draw 0 or 2
              Draw mode. 0 for wire frame piece and 2 for transparent  pieces.
              On slow host, 0 is necessary.

       -x  3...8  -y  3...8  -z  6...18"
              World size : width, height, depth.

              Starts game with smooth drawing.

              In  this  mode,  pieces  don’t  fall.  By the way scores are not

              Next piece is shown.  By the way score are multiplied by 0.7

       -level 0...10
              Level 0 is slow, 10 is  unplayable.   This  option  chooses  the
              starting game level.  Level game increases during game.

       -bloctype 0...2
              0 : Only flat pieces.
              1 : Some 3D pieces.
              2 : All possible pieces with less or equal than 5 cubes.

       -land 0...2
              0 : Small land (3x3x15)
              1 : Big land (5x5x10)
              2 : User land (as defined by options)

       -eyedistance -1...1
              If not 0 the game is with real 3D. But you need to cross-eye (or
              the opposite). The value is positive if your right eye look  the
              left  image  et  the  left  eye  look the right one.  Indicate a
              negative value to swap the two images.


              Directory which contains the score tables and COPYING file  (FSF

              Defaults  for  Xbl,  this  file only contains a data: the option
              line for Xbl.
              xbl*args: -x 5 -y 5 -z 10 -level 0 \
                        -bloctype 2 -land 0 \
                        -draw 2 -smooth -buffer -1 \
                        -keyboard 4 \
                        -keytable14789632azqswx ^[p^C0


              Xbl will search his options in this variable, you can put :
              XBLOPTIONS=-smooth -draw 0export XBLOPTIONS
              in your .profile or .login file.


       If sometime a block fall multiple level at once it indicates that  your
       fps is set too high.

       SOUND isn’t correct on some X server, no possible correction.

       FLICKING  DISPLAY on some X server that doesn’t handle XSync correctly.
       You can turn around using : -buffer 2

       DIRTY POINT on screen because some X servers don’t draw the same pixels
       for  the  same  segment.  You  can  turn around using : -clearline 0 or
       -linewidth 1

       FOCUS WINDOW doesn’t work with OpenWin, so put the cursor in  the  game

       DEMO  mode  seems  to cheat (blocs going through other blocs) but it is
       because  the  visualization  show  a  direct  way  (it  sums  all   the
       transformations  up).  In fact, the real way could use very complex and
       tortuous indirect path.
