Dots and Boxes game


dab[-aw] [-n ngames] [-pc|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 turn.

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.

Support options are:


Don't use the alternate character set.

-n ngames

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


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.


Wait for a character press between games.

xdim and ydim define the size of the board in the x and y dimensions.
