SUDOKU GENERATOR

/prog/ can you make me a sudoku generator that will produce a random sudoku on it's first attempt. Closest I've gotten involved three attempts at max.

#!/bin/sh

SUDOKU_DIR=$HOME/sudoku

mkdir "$SUDOKU_DIR"
cd "$SUDOKU_DIR"
wget -r -np -l0 -N -nH --cut-dirs=2 -P "$SUDOKU_DIR" -A.png http://www.dailysudoku.co.uk/sudoku/png/

find "$SUDOKU_DIR" | grep -E '/[0-9-]+\.png$' | perl -e 'rand($.) < 1 && ($l = $_) while <>; print $l'
