I have to disagree with everything said so far (except the dubloon list, that’s correct). I find that going out and scoring myself is the best way to get lots of dubloons. I almost always go out right away, and half the time I score on the first hit. The only time I stay in my goal is when I accidentally get an anchor and can’t move fast. Call me impatient, but it works.
Check my score And yes, I do lose eventually, but what I do is I don’t send my score until I have 10 points or more – that way I get the 5 dubloon.
Also, a tip: if anyone’s computer is slow, they can just type in the url http://www.neopets.com/games/deckball/game.phtml and it will go to the game, then they can resize the window to make it smaller and they can do better in timed and points! 🙂 It works really well! It also helps in deckswabber to get the full 10 point time reward in the first 5 levels (just change the url to swabber instead of ball) – dolphinling
