About Idle City
Idle City places you in the role of mayor, beginning with a small town on a single island. The central activity is city building: develop your settlement, shape its growth, and work toward creating a thriving urban space.
Expansion is part of the wider journey, with new islands to unlock and cities to establish across different themes and terrains. The idle and simulation elements make the game about gradually growing skylines and managing a broader building project through a casual strategy experience.
