In empire four kingdoms game, you will produce resources such as food, wood, and stone as well as gathering free resources for your troops including rubies as money cash in this game
In the beginning of the game, you will be allowed to attack robber baron castles, even when you are in beginner protection in which you will earn resources once attacking more than one robber baron castle at one time.
In order to get more resources, you can train more troops and siege weapons, then split them up while sending a fraction of your army to each castle at the same time
By doing so they all come back at the same time while bringing you honor and resources.
So try to conquer other kingdoms and outside outposts, form alliances with other kingdoms to multiply your power, increase your honor for victory in the battles, then be the strongest players in the whole kingdom.
When attacking other players after beginner protection is over, you will see from the map is their level and honor whereby you can use espionage to determine how powerful their castle is, how many troops, resource and whatnot.
Just attack the abandoned castles that is the castles abandoned by other players but still produce resources.
Attack them when their troops and defenses have been totally destroyed by other players so that you can use them to farm resources.
The way you protect your castle and the amount of many decorations that is subtracted by the population level and the amount of unrest, which can be caused after an attack when your city is damaged will determine public order of your castle.
For such reasons, you have to fix up your city as quickly as possible, and load your city with decorations to increase the public order.
If you get the bigger green bar at the top of the screen and get the smaller the red bar you will get the higher order, which can lead to more than 100% productivity.
So that you can even get your resource collecting up to 200% with enough decorations and defenses.
You can open the gate to your attackers in the “Manage” menu in that it can be a lifesaver if your troops are out of town fighting battles or you get surrounded by stronger players who like to try to bully you.
Try to keep the gates open while your troops are out fighting, then use their loot to immediately train other troops.
Keep doing so until you have enough troops, defenses and siege weapons so that you can accumulate your power to defeat your repeat attackers in your own castle.
