The principle of this game is "three in a row", which means you have to switch two elements next to each other in order to get 3 or more similar gems in a row. At each level, you have a specific list of goals that need to be completed.
If you have any difficulties passing a level you can use coins to buy a helpful bonus. The coins are also used to restore lives and buy rum for the sailors in order to open new episodes.
Collect treasures, compete with your friends and become a real pirate!
