How do I build a Dyson sphere?

Buy auto-producing facilities — Mining Bot, Auto Drill, Solar Array, Smelter, Moon Base, Asteroid Mine and Mars Colony — to grow your mineral output, then afford the Dyson Sphere and beyond while advancing tiers from Pioneer to Cosmic Civilization.

About the game, how to play & FAQ

How to play Idle Space Colony

Mine (tap): click the main button to extract minerals by hand — useful early and while saving for your first facilities, with occasional rich strikes.
Build facilities: buy auto-producers (Mining Bot, Auto Drill, Solar Array, Smelter, Orbital Factory, Moon Base, Asteroid Mine, Mars Colony, Dyson Sphere…) that yield minerals every second. Every tenth purchase hits a milestone multiplier.
Research upgrades: unlock boosts like Automation, Fusion Cell, Dyson Array and Star Charting to multiply one facility or your whole colony's output.
Advance tiers: reach each mineral floor to rise from Pioneer to Planet Governor, Galaxy Lord, Nebula Overlord and Cosmic Civilization — each grants a permanent global multiplier.
Idle / offline: close the tab and your facilities keep mining — collect offline minerals when you return.

Tips

Always push toward the next tier — advancing multiplies everything, so it usually beats hoarding for one expensive facility like the Dyson Sphere. Use the ×10 / ×100 / Max buy buttons to spend minerals efficiently, and grab every global-output upgrade (Orbital Sync, Dyson Array, Star Charting) as soon as it unlocks.
