Stars are the in-game currency of Polytopia. They are 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 as rewards or through the use of abilities.
