The object of boggle
is to find as many words as
possible on the Boggle board within the three minute time limit. A Boggle
board is a four by four arrangement of Boggle cubes, each side of each cube
displaying a letter of the alphabet or ‘qu’. Words are formed by
finding a sequence of cubes (letters) that are in the game's dictionary. The
(N+1)th cube in the word must be horizontally, vertically, or diagonally
adjacent to the Nth cube. Cubes cannot be reused. Words consist solely of
lower case letters and must be at least 3 letters long.
Command line flags can be given to change the rules of the game:
- Use an alternate five by five arrangement of Boggle cubes.
In this mode the default minimum word length is 4 letters. This
arrangement has been marketed over the years under the names
Big Boggle, Super
Boggle and Boggle Deluxe.
- Run boggle in batch mode. A
boardspec must also be given. The
dictionary is read from stdin and a list of words appearing in
boardspec is printed to stdout.
- Add a so-called challenge cube
to the board, which contains less commonly used letters. The challenge
cube will be displayed in boldface on the board. Depending on the terminal
capabilities, it may be displayed in underline or a different color (such

bottom, in lower case.
