Idle Stars

Tap into a quiet cosmic economy. Build worlds, automate production, launch explorers, meet civilizations, and carry stardust into every new universe.

Begin with one quiet world and turn it into an empire among the stars.

Idle Stars is an incremental strategy game about connected systems. Build solar arrays, mines, laboratories, habitats, and spaceports. Balance five resources, research technologies that change how your economy works, and install AI Directors to automate each world while you are away.

When your first planet is no longer enough, launch explorers into a living galaxy. Colonize new worlds, connect them into sectors, and meet civilizations with their own histories and strengths. Open talks, send envoys, or bring the fleet—the choices you make shape the empire and what the galaxy remembers.

Eventually, growth reaches its limit. Trigger a supernova, carry stardust and permanent upgrades into a fresh universe, and push farther on every cycle.
