are you doing the puzzles on line or on paper? if it's on paper, sometimes you can try writing small numbers in the corner of the boxes for what you think the numbers are. some computer programs also work this way.

Hmm... maybe they see 'Ghost' numbers, trying to imagine what if they wrote that number in the box, where would the other be? This is usually my technique.
