BS(6)                          BSD Games Manual                          BS(6)

NAME
     bs -- battleships game

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

DESCRIPTION
     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 cur-
     sor around the 'sea' with the hack(6) motion keys hjklyubn.

     Note that when selecting a ship to place, you must type the capital let-
     ter (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.

AUTHORS
     Originally written by one Bruce Holloway in 1986.  Salvo mode added by
     Chuck A. DeGaul <cbosgd!cad>.  Visual user interface, 'closepack' option,
     code rewrite and manual page by Eric S. Raymond <esr@snark.thyrsus.com>,
     August 1989.

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