The exchange office can be accessed via the global buildings section in the player profile. In this building, gemstones can be traded in for one another. In addition a random gemstone can be received as a free gift every view hours.
Claiming the gemstone gift triggers a random gemstone drop. The stone will be added to the respective gemstone storage. After activation you will have to wait a certain amount of time to trigger the next gemstone drop. This cool-down can be reduced by upgrading the exchange office.
The „exchange gems“ function allows you to trade in gems for one another. Every kind gem has a certain value that dictates how many gems of a different kind have to be paid to receive one gem of the respective kind. Only a certain kind of gem can be traded for a certain other kind of gem:
- Rubies for Emeralds
- Emeralds for Sapphires
- Sapphires for Rubies
Exchange rates can be reduced by upgrading the exchange office.
Attention: It's not possible ot exchange gemstones if either you have not enough gemstones to start the exchange or the storages can not store more gemstones.
