NAME    [Toc]    [Back]

     bs - battleships game

SYNOPSIS    [Toc]    [Back]

     bs [-b | -s] [-c]

DESCRIPTION    [Toc]    [Back]

     This program allows you to  play  the  familiar  Battleships
game against the
     computer  on  a  10x10  board.   The interface is visual and
largely self-explanatory;
 you place your ships and pick your shots by  moving the cursor
     around  the  `sea'  with  the rogue(6) / hack(6) motion keys
hjklyubn.

     Note that when selecting a ship to place, you must type  the
capital letter
  (these  are,  after  all,  capital ships).  During ship
placement, the
     `r' command may be used to ignore the current  position  and
randomly place
     your  currently  selected  ship.  The `R' command will place
all remaining
     ships randomly.  The ^L command (form feed, ASCII  12)  will
force a screen
     redraw.

     The command-line arguments control game modes:

     -b      Selects  a  `blitz'  variant.  This allows a side to
shoot for as
            long as it continues to score hits.

     -c     Permits ships to  be  placed  adjacently.   Normally,
ships must be
            separated by at least one square of open water.  This
disables
            that check and allows them to close-pack.

     -s     Selects a `salvo' variant.  This allows a player  one
shot per turn
            for  each of his/her ships still afloat.  This puts a
premium on
            scoring hits early and knocking out  some  ships  and
also makes it
            much  harder,  for  example, when you face a superior
force with only
            your PT-boat.

mode added by

NOTES    [Toc]    [Back]

     The  algorithm the computer uses once it has found a ship to
sink is provably
 optimal.  The dispersion criterion for the  random-fire
algorithm may
     not be.
