star is the in-game currency of Polytopia. It is used for training units, buying technologies, harvesting resources, and constructing buildings.
Stars are produced every turn by
cities and buildings like the Customs House. This income is measured in stars per turn (SPT). Stars can also be acquired from rewards or the use of abilities.
