The bundle provides three packages:

• printsudoku, which provides a command \sudoku whose argument is the name of a file containing a puzzle specification;
• solvesudoku, which attempts to find a solution to the puzzle in the file named in the argument; and
• createsudoku, which uses the random package to generate a puzzle according to a bunch of parameters that the user sets via macros.

The bundle comes with a set of ready-prepared puzzle files.
