Rubies

The ruby is the virtual and non-transferable currency of Empire-Strike with which you can get certain improvements to enhance your empire.

Rubies are charged to your personal account and can be used in any of the 3 simultaneous games that normally run on the Empire-Strike server.

You can buy rubies by PAYPAL, Credit cards or by mobile via SMS.

Once the purchase has been made on-line, the rubies are transferred directly to your account and you can dispose of them immediately.

To achieve a balance between players who invest in rubies and those who use the game for free, a weekly usage limit of 300 rubies has been set and is indicated by a counter that is reset every Monday.

Once the rubies have been credited to your account, you will be able to view them in the resource box (desktop version) or in the top bar of the App.

The rubies in your empire can basically be used for 2 things: upgrades and services.
