You should first understand the basic functions of your army base

• Armies that you create will originate in your army base.
  
• In the event one of your armies is defeated, it will be forced to return to your base (effectively leaving you without an army until it arrives in your base).
  It costs resources to move your armies around the map - the further you move your armies, the more resources are consumed.
• Missiles will be launched from the location of your base.
  Missiles have a minimum and maximum range - you will only be able to attack cities with missiles that are within range of your base.
  

Your actions are limited by the resources that you acquire.

• In order to accumulate resources, you have to build farms for food; mines for steel, rare earths, and uranium; and wells for oil.
• Gold is also a needed resource which is primarily acquired from the cities that you occupy.
  
• Gold can also be acquired by selling excess resources.
  
• You can also trade resources with other players through the market.
  

In order to build farms, mines, and wells:

• Open the resources tab.
• Click on Discover.
• Check the taxes.
  Green Circle = 0 tax
  Black Circle = 100 tax
  
• Once you zoom into one of the circles, you should see this.
  
• Click on the green pop-up and press build mine.
  The farms, mines, and wells will expire within a couple days and you'll have to rebuild them.

There are special actions available to you, such as creating a 9th and 10th army, which cost gems.
There are many ways to get gems.

1. Gem hunts

• Click on the gem button, then click gem hunt.
  
• Zoom in all the way towards the center of the circle, where that place is.
• You will see gems when you find that place. Click on the gem and you will receive around 3-5 gems.
• Gem hunts happens every 8 hours
  

2. Alliance Tournaments

• There are alliance tournaments which last 5 days.
  
• After the tournament ends, each of the top 10 players in the top 3 alliances receive gems
  
  The rest of the alliance who has timevalue gets half the rewards.
  (timevalue is the time of occupying the city multiplied by the city value)

3. Everyday, you will receive 5 gems for having a country.

4. Win the lottery.

Armies

• Everytime you create an army, you can name it.
• The maximum number of armies you can have without spending gems is 8.
• You can purchase a 9th army for 50 gems and a 10th army for 100 gems.
• To move an army, click move and drag it to the city you want and click move.

Troops

• When you start, you have 8 armies.
• To train troops, click on edit army.
• Each troop cost 30 gold to recruit.
• Troops are recruited from the city's population. If in the base, they are recruited from the city closest to your base.

Weapons

• To add weapons to your army, you must first build weapons.
• Weapons cost resources to build. Make sure you have enough resources to build weapons.
• Click on the weapon tab.
• Select the weapon you want to build and click produce.
• Select the amount you want to produce.
• Go back to your army and add it into your army.

Army Stats

• To check how many attack points your army has, click on the star beside (ATK). There will be a pop-up which shows how many attack points your army has.
• To check how many HP your army has, click on the star beside (DEF). There will be a pop-up which shows how many HP your army has.
• You cannot attack a city in an alliance territory if the owner of that city is in that alliance.
• Countries give you extra Defence bonus.

Attacking and Defending

• Every successful attack, you will receive 1% attack bonus in your army. For example, if your army has 1000 attack points and you successfully attack someone, you will get a 1% attack bonus, which gives you 1010 attack points. Maximum attack bonus is 100%.
• Everytime you successfully defend your city from someone attacking, you will receive a 1% defence bonus in your army. For example, if your army has 1000 HP and you successfully defend your city, you will get a 1% defence bonus, which gives you 1010 HP. Maximum defence bonus is 100%.
• You can get loot when you win a battle. The loot is a certain percentage of the opponent's resources and gold.
• You can't get loot and attack bonus when you attacking a player which level < 5.
• You can't get loot when you attacking an alliance capital.

Battle Medals

• You can get Battle Medals when attacking or defending in a battle.
• 1 Battle Medal for every 10,000 combat power consumed. If you fail in defense, you can only get 70% of the battle rewards.
• Battle Medals can be used to purchase Items.

Once you have taken over three of more cities, you can create your own country! Choose any of your three cities to form a country in the shape of a triangle.

• The value of the country is determined by the sum of all your cities inside of the triangle.
• All of your cities inside the triangle will receive a defense boost - The amount of the boost is proportional to the country's value or inversely proportional to the country's border length (larger counties will generally have lower defenses).
• Your country will automatically generate 5 gems per day.
• All countries will need expenditure, and the amount is proportional to the country's size and value. If you lose one of the cities or do not have enough gold to sustain your city, your country will disappear and you will not receive any gems.
  

You can choose to play as a lone wolf, team up with an alliance, or create your own alliance. There are perks to being in an alliance: Firstly, all members of the alliance can receive rewards everyday. The amount of reward you received is proportional to the total area of your occupied cities and your alliance territories area (the larger the area, the more rewards you will receive); Secondly, you can participate in the alliance tournament, and the top 10 players in the top 3 alliances are rewarded with gems every 5 days.
