Chests / Collectibles

## Chests

You can unlock Chests as soon as you have got mineshaft number 8 in the Coal Mine. There are seven ways to get Chests in the game:

1. From the Daily Rewards.
2. By watching videos.
3. By buying them for Super Cash in the in-game shop.
4. By completing Expeditions.
5. From Recurring Events, Event Mines and Event Seasons.
6. Get them occasionally by Enter(or Reenter) a Mine.
7. By purchasing Limited Offers.

Chests come in five rarities: Common, Rare, Epic, Legendary and Premium. The Common ones are very easy to get, and the Premium ones don't appear very often!
Inside the Chests you will find different amounts of collectible cards (the better the rarity, the more cards you will get).  Premium Chests reward 10 random, legendary Cards.

The Green Chests can only be purchased (with Super Cash) once per day from the shop, they come in four rarities for each area, and will include only collectibles of a certain area (Elevator, Mineshaft, or Warehouse). This will make it easier to target the collectibles that you are looking to improve the most.

You can view/open your chests either by clicking on the chest symbol at the top left of the mine you are in, or by visiting the "Collectibles" island in the middle of the world map.

## Collectibles

You can only get these from Chests. They give you different bonuses for your Elevator , Warehouse and Mineshafts . They also change how your workers are dressed! You can view your cards on the "Collectibles" island in the middle of the world map.
When you receive the same card several times, it will then level up that card to give you a bigger bonus.

To activate one of the bonuses for all of your mines, simply click on it and then click the green "Activate" button underneath it. You can change your chosen bonus at any time by clicking on a different one and activating it instead.
