The Gem Mine is a place where Gems are dug up from deep depths of the rich earth. You can venture into the mine and invite your Facebook friends on expeditions to uncover forgotten secrets that are buried within the ancient mine.

The mine itself contains a gemstone that you can tap to collect Gems. The Gems are generated consistently over time. You can claim your Gems whenever you want. It is also possible to increase the Gem Mine’s storage and rate of production by either upgrading the building or buying a subscription in the store, which increases its capacity and output by 100%. Moreover, you can also, if you’re lucky, receive a multiplier that amplifies the number of Gems you receive. Multipliers can vary in effect, ranging from 2x to 100x.

Expeditions

Expeditions
There are three types of expeditions:
  • Rare (24 hours)
  • Epic (72 hours)
  • Legendary (168 hours)

The higher the rarity of the expedition the better loot players will receive. With these expeditions players can invite up to 5 friends to venture deeper into the mine. Inviting friends reduces the duration of expeditions by 50% and every expedition gives worthwhile rewards.
