Boom Beach: How To Get Wood, Stone And Iron
When it comes to general resources in Boom Beach, there are three you'll want to keep in mind.
The first is Wood. You'll need wood if you want to complete any sort of building on the island. You mainly get wood by removing trees with the help of a lumberjack (who's available to hire for a few coins), or by setting up a Sawmill to produce it for you. Although you can only set up one Sawmill at a time, it provides a steady amount for you to keep producing. You can also earn extra wood through conquering islands (from enemy resources).
Next up is Stone. This is a wonderful resource, as you can use it to upgrade your buildings to make them stronger against enemy attacks. You can obtain Stones by either opening up a Quarry or cleaning house on an enemy's island or resource base. It's not a bad idea to make your own through the Quarry, though. Set one up whenever you can.
Finally, Iron is another viable material for strengthening your buildings, particularly your headquarters. To get this, you'll need to open up an Iron Mine. Its production is probably the slowest compared to the Sawmill and Quarry, but it's still quite serviceable. Like the others, you can also get it by defeating an enemy on their island.
