About
Start with a single atom and grow an entire universe.
Space Agency Idle is a relaxing idle game about building the cosmos from scratch. Tap to create Energy, invest it in upgrades and watch your universe come to life: stars ignite, planets settle into their orbits and your production climbs to astronomical numbers.
TAP AND GROW
Every tap creates Energy. 30 upgrades, from plasma forges to singularity engines, keep producing it for you, even while you're away.
IGNITE STARS
Energy condenses into Stardust. Ignite 5 kinds of stars that multiply all your production and light up your sky.
DISCOVER PLANETS
Unlock 8 planets, each bigger, rarer and more beautiful than the last. Every new discovery gets its own reveal moment.
TRIGGER THE BIG BANG
Restart the universe with Cosmic Knowledge, invest it in 6 technologies and grow faster with every new cycle.
