In Outpost Kaloki X, players try to address the needs of visiting space voyagers, while simultaneously attempting to meet any special victory conditions for the current scenario. Players do this by analyzing the small supply and demand bars next to each of the five types of service buildings available, such as social or research. When a demand is largely unmet, it represents an opportunity to build a new structure of the appropriate type in order to satisfy that demand and earn money to provide further services. As the game progresses, players can build larger, more expensive structures which satisfy more customers at once with a higher quality of service.
