NAME

       sudoku_generator - generate and solve Sudoku puzzles

SYNOPSIS

       sudoku_generator [-n|--non-sym] [-d|--dump] [givens_count]
       sudoku_generator -s|--solve|-p|--print sudoku_dump

DESCRIPTION

       sudoku_generator  generates, solves and prints Number Place puzzles, so called Sudokus.  A
       Sudoku puzzle consists of 9 x 9 cells subdivided into 9 regions with  3  x  3  cells.  The
       rules  are  simple.  There  have  to  be  the numbers from 1 to 9 in every row, column and
       region.

       givens_count
              Number of givens (<= 81). Default is 36.  Generation of Sudoku  puzzles  with  less
              than 26 givens takes very long.

       sudoku_dump
              String with 81 * 1-9 or _ (+ ignored).
