Here are some easy ways to get a good score on Dubloon Disaster!
1. Set a goal for yourself. Dont send in your score unless you get over your goal. My goal is 170 points, because above that and you get 1000nps.
2. After you get at least of the way to your goal, go to an area where there are no mines (the small black and red things) and type in SCALLYWAGS. It creates a whirlpool. If you move right after you create the whirlpool, it will close, so wait for a split second, then move. Be careful or you might get sucked into the whirl pool!
