You have to sell spices silk and other stuff
Simple. There are trading posts at each island all you have to do is sell and buy things from the post.
Collect the five map pieces (one on each of the trading islands) and join them to see the sixth island, Skullduggery. Once it appears on the map, you can actually go there, but nothing happens there until the end of the game. (see the related question)
Well first of all when you go to skullduggery island there is a map but it was broken up at each island. All you have to do is complete a small task on Fort Ridley (where you began you quest) and then you will have a small/weak boat. You sail North-West from Fort Ridley.
Well on each island, usually in a building there is someone you can hire. each of them have different uses and expenses. All them cost doubloons to hire.
The 6th outlying island is hidden until you collect all 5 map pieces (one from each of the trading islands). It only comes into play after you have driven off Captain Crawfish and have the Treasure Location card from the Governor. Travel to Skullduggery and use the bone shovel to dig at the marked location.
Collect the 5 map pieces, one from each of the trading islands, and the hidden island will appear on the map. You cannot do anything there until you have defeated Captain Crawfish.
Well, You Have To Buy (With Dabloons) A Character (On Each Island).... But They'll Cost Alot of Dabloons!!
you go around to each place and sell your cargo
use your map to travel to islands and solve puzzles and you should get a little map piece in each island and you could even beat captain crawfish and complete the island
The trading posts, are on each port such as dragon port , the parrot port etc.
easy. get a ship. go to five places you get to sail to. each place has a peace.
You arrive at Fort Ridley, the Main Street island. Above are Dragon Cove and Bouffant Bay. To the right is Parrot Port. At the bottom left and right are Pirate Outpost and Golden Harbor. Once you have collected a map piece from each of the 5 islands, the 6th outlying island (Skullduggery) will appear near the Pirate Outpost.
