Requirements: Level 15+

 

The event lasts 6 days.

 

When you access the event, you see a field with cells. You need to dig up these cells using shovels and tractors from the right side of the event screen. Click on a shovel or tractor to select it and use it on the field.

 

Each cell that you dig up brings you rewards. The cells that you have already opened are marked accordingly. You can receive a reward from each cell only once.
 

1. Choose the tool you'd like to dig with on the right side of the event window.

2. Click on a cell on the field to dig. 
There are 2 types of cells: simple and complex ones.
Simple cells open after one dig with shovel/tractor. If you dig a cell and receive a reward immediately - it is a simple cell.
Complex cells open after two digs with shovel/tractor. If you dig a cell and see a chest - it is a complex cell. You need to dig it once again to receive a reward.

3. Receive the reward! The rewards include superbucks, seasonal currency, Explorer's coins and more!

4. Continue digging to find a magic key that can be exchanged for one of the two main rewards.

Crystals

During the event, crystals with a reward inside may appear on the field. Each crystal contains a reward that is visible.

To get a reward from a crystal, you need to use a shovel or a tractor as usual. After that, the crystal will disappear, and you will receive the reward from it.

Each crystal has a 1-minute timer. If you do not use a shovel or a tractor on it during this time, the crystal will disappear from the field along with the reward.

You start with 10 shovels.

 

You can also claim:

 

 

Please note: You can have 35 shovels maximum at any given time. If you reach this limit, you won't be able to claim/receive any new shovels until you spend at least one.

Note: On the field you might find a discount coupon: use it to get a discount on the shovel offers! The discount coupon lasts for 12 hours once you find it, but you can only use it 1 time.

Shovel: digs only in 1 square

 

 

Tractor: digs in 4 squares at once. If the tractor's digging zone intersected with an already uncovered square(s), these squares will be refunded to you in the form of shovels.

 

 

Metal detector: helps identify cells with hidden treasure chests.

Once selected, it can check the area of 9 squares. 

 

Choose the area you wish to check and click on it. If there are cells with hidden treasure chests (complex cells), they will be marked with a cross once you apply the tool.

 

The identified complex cells (cells marked with a cross) require two digs with any tool. The remaining cells are simple ones - they will reveal a reward after one dig.

You need to find a magic key on the event field to receive the main reward. There is only one key per field and it is not easy to find. Once you find it, you can exchange it for any of the two main rewards.
You can obtain a magic key only from a simple cell.

Once you obtain a key, you can refresh the game field. If you continue playing on the same field and open all the cells, the field will refresh automatically.

The main rewards in this event are:

Soldiers' and Sailors' Monument
size 9x9, can be placed anywhere.

Please note:  If you fail to exchange your magic key(s) for the building(s) before the event ends, each key will be converted into 750 lucky cards. You will not be able to claim/receive a building in this case.

Please note: The 3rd magic key can be used to open a chest with 750 lucky cards that you can then exchange for the blueprints of chest buildings in the blueprint shop.
