The game uses an energy system - the player can only perform a limited number of actions before they have to wait for their energy to refill. Some items can only be purchased with premium currencies purchased through micro-transactions. Premium currency can also be used to rush buildings so that they finish producing resources faster, purchase items needed to build businesses, and buy land expansions. Also, coins and energy can be purchased with micro-transactions. Players can visit friends' colonies to receive bonus resources.
