At the moment i am thinking that visiting the times, telegraph and other sites to grab working grids and adding them to a list of possible grids to generate is cheating somewhat! What i would like is some pseudo code that i can adapt to generate grids for different difficulties of sudoku puzzles.

Unfortunately, what 'level' a board is is very subjective. I've seen puzzles described as difficult by newspapers which have required nothing more complex than what I call hidden singles. Obviously, games published in newspapers tend to be much less challenging than those found on numerous websites. The *really* difficult ones are best tackled with a computer 'solver' which will at least simplify 'pencil-mark' (candidate) manipulation. If I was designing a puzzle generator, it seems intuitive to base the level of difficulty on the complexity of the solving techniques. Ultimately, you get to decide, if you generate your own puzzles .
