Supernova: Idle Star Forge

New: global leaderboards — race the galaxy for Neutron Cores and Supernovae. Still no ads, still fully offline. Your next universe is one tap away.

Fuse hydrogen into a living star. Grow it. Then blow it up — on purpose.

SUPERNOVA is a premium-feel idle game about running a cosmic forge. Tap to spark fusion, build 12 generators from Hydrogen Wisp to Singularity Seed, and watch your star physically evolve — protostar, 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.

WHY YOU'LL STAY • Real progress while you're away — production continues offline (extend the cap up to 24 hours with research), and a welcome-back doubler greets your return • A star that actually changes — five visual stages, rendered live, no canned art • Prestige that feels like a finale — a hand-built supernova cinematic, then a stronger start • Numbers that get gloriously big — Million, Septillion, and far beyond • Milestones every few minutes early on, deep multiplier stacking later • Daily missions and streaks that respect your time • 20 research upgrades that shape every run

FAIR BY DESIGN • No ads. None. • No energy bars, no forced waits, no progress walls • Fully offline — no account, no sign-in, no internet required • Nothing collected, nothing tracked • Optional purchases exist (time warps, photons, a one-time Supporter Pack), and the entire game is balanced to be completed 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 boost, fill your Piggy Bank
4. Reach collapse readiness... and go SUPERNOVA
5. Keep your Neutron Cores forever. Start again, faster.

Your first universe is waiting. It starts with one atom.
