DAB(6)                           Games Manual                           DAB(6)

     dab - Dots and Boxes game

     dab [-aw] [-n ngames] [-p <c|h><c|h>] [xdim [ydim]]

     dab is a game where each player tries to complete the most boxes.  A turn
     consists of putting one border of a box; the player setting the fourth
     and final border of a box gets the point for the box and has another

     The keys used are the vi keys: k for up, j for down, h for left, and l
     for right.  To switch between even and odd rows, use one of the following
     keys: u (diagonal right up), y (diagonal left up), b (diagonal left
     down), n (diagonal right down); <space> sets a new border, CTRL-L and
     CTRL-R redraw the screen, and q quits the game.

     Supported options are:

     -a               Don't use the alternate character set.

     -n ngames        ngames games will be played.  (Especially useful in -p
                      cc mode.)

     -p <c|h><c|h>    Select which of the two players is a human or a
                      computer.  The first argument is the first player; c
                      stands for computer and h for human.

     -w               Wait for a character press between games.

     xdim and ydim define the size of the board in the x and y dimensions.  If
     the dimensions specified are 0 then the maximum dimensions for the size
     of the screen are used.
