Gold can be aqcuired a few different ways:

  1. Taxing peasants
  2. Selling items at the market
  3. Sieging enemy players & Ai castles

Taxing peasants:

Taxing peasants is your most consistent way of generating Gold.  To tax a peasant, you must first build a Hovel and wait for a peseant to move in. Once a peasant has moved in, you can tap on the hovel to open the peasant interaction panel.

Once opened, the interface will show you the peasants "needs". Provided you have these items in your storage, you can interact with the large tile buttons to give the specified items to peasant, raising their happiness. 

Happiness is displayed in the bottom right of the panel, indicated by the heart icon. The more happiness a peasant has, the more gold you can tax them for. Press the "Tax" button to tax the pesant and receive the specified amount of Gold.

Selling Items At The Market:

Selling to the market can be a great way to earn gold in a pinch. Once you've built a market. Tap on it to view the market panel.

Once you open the market panel, you can see what items are able to be sold at the moment. To sell items, you must have enough of the specified items in your storage. If you do not have enough to sell, the text will display red.  Once you have enough of the specified item, you can tap the button to sell your items in exchange for gold.

Sieging other players & AI Castles 

Defeating enemy Castles will reward you Gold. You can attack enemy castles via the Map button in the bottom right of the screen. At the end of a siege, you will be able to see your rewards via the Siege Assessment Panel.
