Eliminate all objects that do not obey the clue rules first. There might still be more than one possibility. If so, move on to the next clue. Go through all the clues this way until you can start locking down objects. If you start a round with objects that have been locked down for you, look for clues that contain that object. This is a quick way to lock down other objects. Work on clues with high numbers, since there will be fewer objects that match the rule. Skip over any clue that does not immediately provide an opportunity to narrow down objects. Work on other clues first. Hover over a clue to quickly highlight all of the objects on the board.
