Your main objective is to unlock all the Islands featured in Pirate Kings game. And you have to defend them too. Other players will attack these Islands for coins, if the shield is active(you get defensive shield by spinning the wheel), you don’t need to worry. If not, then they can destroy your ship or treasury or castle for coins. If destroyed, you need to fix those items using gold/stars. You will lose that item or item will disappear if the enemy targets it again; it means, you will have to build it again. So, fix it to save gold.
