Archaeological expeditions last 9 days and are available from level 15.

These are the rules:

There are 6 maps in total in expeditions. They repeat endlessly, but with each transition, they are updated - you can re-collect resources from them. This will help you  collect the necessary items sooner!

There are a number of tasks on every map. When you complete the tasks, you receive tiny shards that you can use to restore the museum exhibits in the Archaeological Museum.

The Archaeological Museum is located in your city and remains where you decide to place it. It will remain there after the completion of the expeditions and will bring you profit.

Now let's go over the basic rules again:

In each location, you need to complete a series of tasks and remove many obstacles. These obstacles will help you complete tasks. You can find the task you need to complete on the left side of the expedition screen.

These tasks will help you achieve the main goal of the expedition. This goal is to get as many tiny shards as possible and restore the exhibits in the museum. Exposition profit depends on how many exhibits you have; the total profit of the museum depends on how many exhibits you exhibited and how many exhibits there are in each of them.

Also, for club activity in club excavations, you can get an artifact fragment.This item allows you to spend less tiny shards to restore exhibits. Don't forget to click on it to activate it!

Once you have completed all the tasks in the current location, you will return to the place where you started the location from, and the following message will appear:

If you want to go to the next location, the following message will appear:

If you press the green button, you will be taken to the next location of the expedition.

PLEASE NOTE: after you have completed all the tasks in the location and left it, you will not be able to return there. You will only be able to access this location again after you have completed all the other locations first!

Each location has the following buildings:

You can use the nuts and berries collected at the location to produce expedition energy in the field kitchen.

You can use the items you collect in the location to buy more expedition energy.

If your Archaeological Museum has not yet been maxed out, you will also be able to purchase the following items from the Mobile Stand:

You will be able to apply these items in the 'Upgrades' tab of your museum to unlock more halls.

The amount of energy you can buy in the stand is not limited, and you can buy only one upgrade item of each type per location. After you move to the next location, they will appear in the mobile stand again.

PLEASE NOTE: after you have completed all the tasks in the location and left it, you will not be able to return there. You will only be able to access this location again after you have completed all the other locations first! So don't forget to buy everything you need in the Mobile Stand before you leave the location!

This van will immediately take you to your Archaeological Museum. Now you don't have to go back to your city to check your expositions! Just click on the van and the Archaeological Museum window will appear.

Excavation Intensity: You need to be a member of the club and spend expedition energy. The more expedition energy the participants spend, the more bonus energy they will be able to receive from the expedition.

Note:
-- The amount of energy that goes towards club goals is limited for each player. If you spend more energy, it will not count.
-- The timer resets daily at 12:00 UTC (Coordinated Universal Time, 3 hours behind Moscow time)
