       This manpage documents version 0.9.5 of xpuyopuyo.

       Xpuyopuyo  is  a  Tetris-like  puzzle game where you strive to match up
       four ‘‘blobs’’ of the same color.  Each match  gives  you  points,  and
       also  dumps  gray  rocks  on  your  opponent  which  are irritating and
       troublesome to get rid of.  Multiple matches at  one  time  score  more
       points,  and result in more rocks being dumped on the opponent (much to
       their dismay).  First person to fill  up  their  screen  with  puyopuyo
       blobs loses.

       The  game  features an AI, and is capable of single-player, human-human
       play, human-AI gameplay, or AI-AI gameplay (demo mode).  It  will  keep
       track  of  the  total  number  of matches each player recieves, and the
       number of single-matches, double-matches, triple-matches, etc. as well.

       We  ported  it  overnight  to  Linux, so we could play whenever we felt
       like. The AI’s evolved more slowly; the original implementation took  a
       week  to  develop.  The current implementation is evolved using genetic
       algorithms;  more  documentation  on   this   is   available   in   the
       distribution.  I always welcome new AI rules, or suggestions to improve
       the AI.

       This version is modelled on several other versions we have seen around;
       the  original (which I have not had the opportunity to play) is made by

       I release this so others may enjoy it. If this game causes someone  out
       their to flame/flunk out of college, then apologies but it’s the game’s
       fault, not mine :). Additional information, documentation is  available
       in the distribution.


       The  idea  is to match up colored blobs together.  A match is any chain
       of 4 or more blobs of the same color, that are adjacent to  each  other
       (up,  down,  right,  or left).  The game gives you a playing piece with
       two colored blobs, which you can move  around  the  playing  field  and
       rotate  as  it  falls  to  the  ground.   In gameplay, it is similar to

       You get points for completing a match, and all blobs  involved  in  the
       match  will  disappear.   Larger matches (matches of more than 4 blobs)
       and multiple matches at the same time score much more points.

       Also, if you are in a 2-player game, then several rocks will be  dumped
       on  your  opponent  when  you complete a match.  Rocks have no color; a
       chain of rocks does not complete a match.  However, any  rock  adjacent
       to  a  match  will  be  eliminated.  Again, larger matches and multiple
       matches at the same time will cause more rocks to be  dumped  onto  the

       (The  truly  unfortunate  may discover the indestructible rock or other
       forms of evil rocks.  You are truly fortunate if you  survive  such  an

       The  game ends when you fill up your playing field.  So try to keep the
       playing field as low as possible.  See the options below  for  some  of
       the features of the game you can enable.


       Many  of  xpuyopuyo’s options may be configured by the command line.  A
       summary and description of available options is below.  Note, that some
       options  might  not be available, depending on how you built xpuyopuyo.
       To see a list of supported options, run xpuyopuyo --help.  Options  are
       processed in the order they are read; later options can clobber earlier
       options, so it’s good to make the difficulty option the first one.

       General options:

       -h, --help
              Display a summary of the options available.

              This is insanity, Max!  Or what if it’s genius?

       -1, --oneplayer
              Select one player game.   No  rocks  in  this  version.   Either
              player’s controls will work in this mode.

       -2, --twoplayer
              Select two player game, human versus human.  Player 1’s controls
              are on the keyboard, and player 2’s are in  the  numeric  keypad
              (this may be configured, however).

       -a, --aiplayer
              Select  two player game, human versus computer.  Either player’s
              controls will work for the human player.

       -d, --demo
              Select two player game, computer versus computer.  Fun to  setup
              two  different  AI’s  against  each other and watch them go (the
              current longest running demo game I’ve seen was 57  hours  long,
              and  that was only ended by a bug in the timer code which caused
              one of the AI’s to pause.   By  the  time  I  noticed  what  had
              happened, the other AI had racked up an unbelievable 6,000 rocks
              against his frozen opponent ...).

       -e, --easy
              Easy gameplay. Enables options for easier gameplay.  This option
              is   currently  equivalent  to  --noaidrop  -number=4  --nullify

       -m, --medium
              Medium gameplay. Enables more difficult round.  Currently,  this
              is  equivalent  to  the  following: --aidrop -number=5 --nullify

       -H, --hard
              Hard  gameplay.  Enables  the  most   difficult   of   gameplay.
              Currently,   this  is  equivalent  to  the  following:  --aidrop
              -number=6  --nonullify  --indestructibles.   Later  options  can
              override the options set by -e, -m, or -H.

       -n, --number=n
              Specify  the number of colors to use.  This value can range from
              4 to 6.  The default is set by the difficulty level.

       -t, --restart
              This is a toggle option.  Automatically restart after  a  ‘‘Game
              Over’’.   Useful  when combined with the -d flag.  The inversion
              of this flag is -/t, --norestart.

       -T, --tutorial
              This is a toggle option.  Enable  tutorial  mode.   In  tutorial
              mode,  an  AI  will  assist  you by choosing a move it thinks is
              appropriate.  You may still control the piece  with  the  player
              controls.  The inversion of this flag is -/T, --notutorial.

       --theme name
              Select a theme to use on startup.  The default is ‘‘default’’.

              This is a toggle option.  When set, tooltips are displayed.  The
              default is for this flag to be set.  To turn off  tooltips,  use

              This  is  a  toggle  option.   When set, no output is printed to
              stdout.  The default is for this flag to be  cleared.   To  turn
              off quiet use --noquiet.

       Sound Options:

       -S, --sound
              This  is  a  toggle option that enables music and sound effects.
              The inversion of this flag is -/S, --nosound.

              This is a toggle option that enables use  of  the  high  quality
              mixer provided by mikmod.  Depending on your soundcard, this may
              have no effect.  Defaults to  off,  to  turn  off  high  quality
              mixing use --nohqmixer.

              This is a toggle option that enables sound effects.  Defaults to
              on when sound is supported.   To  turn  off  sound  effects  use

       Advanced Options:

              Specify the width of the playing field.  The default is 6.

              Specify the height of the playing field.  The default is 14.

              Specify  the  number  of  blobs in a chain required for a match.
              The default is 4.  For more difficult  gameplay,  increase  this

       -U, --nullify
              This  is  a  toggle option.  When on, your rocks can nullify the
              opponents rocks.  During the game, when  you  complete  a  match
              rocks are sent to the opponent, but they do not fall until their
              playing piece lands.  In the meantime, if  they  accumulate  any
              rocks  against you, the rocks may instead be used to nullify the
              rocks accumulated against them.  If this option is off, then all
              rocks  that  are  sent  will fall on the opponent -- eventually.
              This option is on in easier gameplay; the inversion of this flag
              is -/U, --nonullify.

       -I, --indestructibles
              This  is  a toggle option.  When on, "indestructible" blocks are
              allowed in the game.  If a player accumulates a large number  of
              matches  at  once (a quintuple-match is usually enough), then in
              addition to several rows of rocks being dumped on the  opponent,
              an  indestructible  block  will also fall on the opponent.  This
              rock cannot be destroyed, and the best the opponent  can  do  is
              try  to  get  it down to the bottom of the screen where it is at
              least out of the way.  This mode of gameplay can make life  very
              interesting,  indeed.   This  is only enabled by default on hard
              difficulty;   the   inverwsion   of   this    flag    is    -/I,

       Player Options:

       -s, --speed=n
              Set the speed for falling blocks for the player, in milliseconds
              per drop.  The default is determined  by  difficulty  level.   A
              typical value is 350.

       -A, --accel=n
              Set  the  acceleration  of the speed over time, in percentage of
              time lost per minute.  This speeds the game up  over  time.   An
              acceleration  is  only  enabled on the harder difficulty levels.
              The acceleration is a floating-point value between 0 and 1.

       AI Options:

       -r, --airule2=n
              Select the AI rule for the right player.  This option is  better
              set  in  the  user  interface,  under the AI menu.  n must be an
              integer value.  If n is random then a random AI is chosen.

       -R, --airule1=n
              Select the AI rule for the left player.  This option  is  better
              set  in  the  user  interface,  under the AI menu.  n must be an
              integer value.  If n is random then a random AI is chosen.

       -c, --aiscore
              This is a toggle option.  This is a debug option, and is  better
              left turned off.  If set, the "AI score" is displayed instead of
              the next piece in the main game.  The AI score  is  the  ranking
              for  the  current  move;  higher  scores  mean  the  AI judged a
              particular move to be "better".  Note that since each AI has its
              own  ideas  on  what  makes  a  good  move, this score is highly
              dependent on the mindset of the selected AI.  There’s  not  even
              any  attempt  to  normalise  the  AI  score with scores from its
              peers.  So this number  cannot  be  meaningfully  compared  with
              scores  for  other  AI’s.   The inversion of this option is -/c,

       -i, --aidrop
              This is a toggle option.  If set, the  AI  is  allowed  to  drop
              pieces  when  the human opponent drops a piece.  This allows the
              AI to  keep  up  with  human  players,  and  makes  for  a  more
              challenging  game.   This  option  is  on  by  default on higher
              difficulty levels; the inversion of this is -/i, --noaidrop.

       Network Options:

              This starts a new server.  The server has the advantage of being
              able  to  set  the  game options.  It will wait for a connection
              from a client, then the game may begin.  The server will  listen
              on the default port unless --port is also given.

              This  connects  to the server specified.  The connection will be
              made to the default port on the server given, unless the  --port
              option is also given.

              This  specifies  an alternate port than the default, for network

              Enables AI in a network game.  This is  intended  for  debugging
              only.  This is a toggle option; its inverse is --nonetworkai.

       Tournament Options:

       The  tournament options are for AI breeding mode only, and are not well
       documented.  They are: -z, --tournament, -Z, --hypertournament, and -Y

       In the GTK version, there will be exactly one indestructible  block  in
       the About box.  Curious, don’t you think?


       The  player  controls are configurable in the game.  They may be viewed
       and/or redefined in the Options menu.  You can define up to three  keys
       per  action per player.  The actions are left, right, rotate, and drop.

       Note, that when you assign keys, key combinations are not allowed,  and
       you  should  probably  avoid  attempting to assign a modifier key.  The
       keys Enter, P, and Escape will restart the current game, pause a  game,
       and end the current game (respectively) unless you assign these keys to
       a player control.  If you assign these keys as player controls, you can
       still use Ctrl-R, Ctrl-Z, and Ctrl-P to perform the same actions.

       When  in  single-player  or  human-AI mode, you may use either player’s
       controls to control your game field.


       Network gameplay is much like normal 2-player gameplay, except you must
       first setup a network connection between two games.  One xpuyopuyo game
       will act as a server, and the other will act as a  client.   First,  on
       the  server side, select the Network menu, Server and click Ok (you may
       change the port to listen to, if you like).  Then on the  client  side,
       select  the  Network, Client Connection.  Enter the machine name of the
       server and the port number to use (if you changed it in the server) and
       click Ok.

       To  begin a network game, both players must select New Game in the Game
       menu.  The game will wait until both players are ready before  starting
       the game.


       AI’s are created using Genetic Algorithms.  The flexible formulas allow
       the AI to take advantage of certain scenarios,  and  allow  the  AI  to
       weight  them  accordingly.  The rules are changing constantly as the AI
       evolves, and suggestions on new rules are welcome. A  general  list  of
       strategies follows (not sorted in any particular order).  The AI checks
       every possible move with the  current  piece  and  uses  the  rules  it
       evolved to determine which is the best move.

       Distance from top of playing field
              We  don’t  want  the AI to stack up all its pieces at the top of
              the screen.

       Hard limit to the height of structures
              As much as we don’t like height, we really  don’t  want  the  AI
              building  things  within  the  top four or so rows of the field.
              This rule carries a lot of weight in all AI personalities.

       Opportunity to complete a match

       Bonus to complete several matches at once
              The AI decides this by simulating what would happen  if  it  put
              the game piece in various locations.

       Penalty for blocking a potential match
              For  example, covering a hole with three blobs of the same color
              already present).  Some AI’s choose to break this rule more than
              others;  in general these AI’s tend to get more multiple-matches
              (often triples or quadruples).

       Eliminating rocks
              Some AI’s consider it a small benefit to  try  to  eliminate  as
              many  rocks as possible.  If the AI has a choice of two matches,
              the deciding factor could be in which one eliminates more rocks.

              be  set from the interface, there should be no need to edit this
