About Supernova: Idle Star Forge
Fuse hydrogen into a living star. Grow it. Then blow it up — on purpose.
SUPERNOVA is an offline idle space game: an incremental clicker where you run a cosmic forge in deep space. Tap to spark fusion, build 12 generators from Hydrogen Wisp to Singularity Seed, and watch your star physically evolve — protostar, main sequence, blue giant, red supergiant — until it is ready to collapse. Detonating it is the point: every supernova grants Neutron Cores, permanent power that makes each new universe faster than the last. Go far enough and the Dark Sector opens, with its own engines and Dark Matter.
WHY YOU'LL STAY
• Real progress while you're away — production continues offline, and research extends the cap to 24 hours
• A star that actually changes — five stages, rendered live, no canned art
• Prestige that feels like a finale, then a stronger start
• Numbers that get gloriously big — Million, Septillion, and far beyond
• Research upgrades that shape every run
• Classic incremental pacing — tap, buy, double, prestige, repeat
• Galaxies, Contracts and Expeditions once the forge is running
• Constellations to chart, Skies to collect, Forge Works to build
• Daily and weekly missions and streaks that respect your time
FAIR BY DESIGN
• No ads. None.
• No energy bars, no forced waits, no progress walls
• Plays offline — no account needed
• No wifi needed — the whole game runs on your device
• No analytics and no tracking
• Optional purchases exist (time warps, photons, one-time packs and an optional monthly Stellar Pass), and the game is balanced to be finished without spending anything
THE LOOP
1. Tap your star and let generators forge Stardust
2. Hit ownership milestones — each one doubles a generator's output
3. Buy research, stack a Photon Surge, fill your Piggy Bank
4. Detonate. Bank Neutron Cores. Begin again, faster.
IN YOUR LANGUAGE
33 languages, each with its own names for large numbers and its own decimal mark. Pick one in Settings without changing your device.
If you like idle clickers, incremental games and space games that respect your time, this one is for you.

What’s new
Version 1.3.25 · Updated October 20, 2026
The leaderboard works again. Neutron Cores, Supernovae and Expedition were unreachable for every player: the game asked Google Play Games for more rows than it allows, and the call failed instead of returning fewer. Fixed. Open the trophy and sign in to Google Play Games to join the ranking - the screen now says so, instead of asking you to detonate a supernova first.
User reviews
really fun game it's really cool and easy to progress
Great game! It would be really cool if the star colors matched the colors on the Herzprung-Russell Diagram of stellar evolution🙂
