I disagree with the combo argument. Combos help out your score, but clearing the board faster does more to your score than a combo would. The general idea is to try and clear the board as quick as possible without using a lot of moves. A problem a lot of people have with the d-nav puzzle is that they think they're bad because they score low when they first try it. The higher the level you go, the easier it is for you to score higher, because you have more slots to fill. This is why in all of the tourneys for d-nav, people don't use alts, but instead, use their mains as you must have GM+ in order to receive the max amount of slots. Max amount of slots = max amount of score.
