Launch from a single barren rock and grow it into a galaxy-spanning empire — one tap at a time. Cosmic Idle: Galaxy Tycoon is a relaxing yet deep space idle game where your colonies keep working even while you're away.
🌍 TERRAFORM EVERY WORLD
Tap a dead planet to spark its transformation — watch oceans form, continents bloom, and city lights flicker on across a living, hand-crafted surface. Every world is unique.
🏗️ BUILD A COSMIC CIVILIZATION
Unlock 50+ structures across six eras — from your first Landfall outpost to a Stellar megacivilization. Balance Energy, Minerals, Food and Research as your population grows and your economy compounds.
🚀 COLONIZE THE GALAXY
Chart a gorgeous star map, warp between three star systems, and claim new worlds. Each colony boosts your entire empire — the further you reach, the faster you grow.
⚔️ WAR ON THE SWARM
Build fleets, liberate Swarm-held planets, and defend your colonies from raids. Power up, strike, and reclaim the stars.
♾️ ASCEND & PRESTIGE
Maxed a planet? Ascend it to a new epoch for permanent bonuses, then prestige your whole empire for galaxy-wide multipliers. The idle loop never ends.
💤 PROGRESS WHILE YOU SLEEP
True offline earnings — come back to a pile of resources and a Welcome Back reward. Perfect for short bursts or long idle sessions.
