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. Built by a solo developer in SwiftUI and SpriteKit. Every pixel is procedural — no asset packs, no stock art. Dark theme, tuned haptics, Reduce Motion respected. Your first universe is waiting. It starts with one atom.

Your role: tap the desk, and money comes out. Perform the role until the money performs itself. Questions are discouraged. INTEREST.EXE is a deadpan idle game about compound interest, corporate life, and the people who post about both. Grind at your cubicle. Buy instruments. Watch the line. Become a concept. • NUMBER GOES UP: every digit of your balance counts live, from $0.05 past the GDP of Earth • A PORTFOLIO YOU CAN SEE: piggy banks stack into towers, a rocket lands on your windowsill, at some point you own a small sun • TRADE THE LINE: buy low, sell high on a live market running on a tiny 3D laptop • SHAKE FOR VOLATILITY: HR will not elaborate • SURVIVE THE MARKET: recessions, audits, meme rallies, AI winters, tax season • CLIMB THE LADDER: from folding shirts to selling a course about selling courses to becoming a concept • COLLAPSE THE ECONOMY: on purpose, for bonds • WIN THE GAME: by exceeding the gross domestic product of Earth. The number keeps going up afterwards. That was always the point. Free to play, and the ads respect you: they only ever play when YOU press a button asking for one, in exchange for a boost. Nothing interrupts play, ever. No accounts, no cloud: your empire lives on your phone.

Verdict
The clearest difference is in-app purchases: INTEREST.EXE at none against Supernova's 10. INTEREST.EXE also leads on iOS requirement (15.0 vs 17.0). Supernova's advantage is ads (none vs shown) and update cadence (every 2 days vs every 6 days). On price there is nothing between them.
