In general, the higher the number after the underscore the harder the puzzle. *_157.pdf should be easier than *_656.pdf. These puzzles are like online 'auto-candidate mode' puzzles - they're completely penciled and ready-to-go (except you have to update the relevant candidate lists as you go along).
