Stellar Dominion: Idle Galaxy

About Stellar Dominion: Idle Galaxy

You begin in a place you know: Earth, orbiting our Sun. You end up somewhere almost no one ever sees — face to face with a black hole.

Stellar Dominion is a free idle space game — an incremental empire builder about the wonder of the cosmos. Expand outward from the real solar system, one world at a time, until the rarest objects in the galaxy are within reach. True idle progress: your empire keeps earning while you're away, offline earnings wait for you when you return, and nothing is ever required to progress. No account needed — just tap play.

🌍 START AT HOME
Begin at Earth and colonise the real solar system — Mercury, Venus and Mars, then terraform the gas giants Jupiter and Saturn and the distant ice worlds Uranus and Neptune. Real planets, real positions.

🚀 EXPAND ACROSS THE GALAXY
Warp to other suns: hand-crafted real stars like Vega, Betelgeuse, Rigel, Deneb and Eta Carinae, then procedurally generated systems spanning every spectral class — from blazing blue O-giants to deep-red dwarfs, each with its own colour and feel.

🕳️ DISCOVER THE RARE & THE STRANGE
This is the payoff. Out in the dark wait the objects that make astronomers hold their breath:
• A NEUTRON STAR (PSR Vela) — city-sized, impossibly dense
• A WHITE DWARF (Van Maanen's Star) — the glowing ember of a dead sun
• A BLACK HOLE (Cygnus X-1) — rendered with a real rotating accretion disc, event horizon and photon ring
Reaching a black hole is a genuine moment. You earned it, one

🪐 LIVE PROCEDURAL WORLDS
Every planet is drawn in real time with a procedural shader, so no two worlds look alike — all set against animated starfields and drifting nebulae.

🛰️ BUILD A REAL EMPIRE
• Raise colonies — extractors, habitats, solar power and defenyou have to balance
• Grow population to boost your yield in this resource-management tycoon loop • Run trade fleets of drones, freighters, haulers and capital income
• Climb a research tree across Credits, Helium-3, Research Points and a rare premium currency — and because each world TYPE specialises, you're not colonising the next planet, you're colonising the RIGHT one
• Idle strategy, not idle clicking: every warp, tech and trade route is a real decision

🤖 MEET ATLAS, YOUR ONBOARD AI
ATLAS can auto-manage research, colonisation and trade and offt run hands-off like a true AFK idle game, or play hands-on for a +15% engaged bonus — active play is rewarded, never required. Offline earnings keep the empire growing between sessions, and an optional cloud save
keeps your progress safe across devices.

🌌 COLLAPSE A RUN INTO A SINGULARITY
Prestige your empire into a singularity to earn Galactic Cores, then spend them on a permanent upgrade tree. Each new run offers a choice of modifiers, so no two journeys feel the same — and the endgame capstone unlocall output.

✨ ALWAYS SOMETHING NEW
Levels and XP, achievements, an in-game codex, daily streaks and missions, weekly reports, random galactic events, tappable asteroid drops, an original
soundtrack and tactile haptics.

Free to play, with optional in-app purchases (premium-currencyes like Ad-Free and ATLAS Pro). Includes a small banner ad, arare interstitial after big milestones, and optional rewarded ads you choose to watch — the Ad-Free and ATLAS Pro upgrades remove all ads. Nothing is ever required to progress.

If you love idle games, incremental clickers, space tycoons ortellar Dominion turns a few minutes of attention — or none atall — into an empire that spans the stars.

The universe is vast, ancient and quietly waiting. Start at home. See how far you can go.
