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.

The Earth is Flat!

Features
Read full description

The globe is a lie. The truth is flat. And someone has to spread it — one tap at a time. The Earth Is Flat is a tongue-in-cheek idle clicker about building the world's most dedicated (and most misinformed) movement. Tap to spread the truth, recruit true believers to keep the operation running while you're away, and grow from a shed with a whiteboard into a globe-denying media empire. Then, when you've earned enough, trigger The Great Awakening — start over with permanent Devotees who make every future run mightier. Because real conviction never stops. It just resets and comes back stronger. WHAT YOU'LL DO • TAP THE TRUTH — every tap spreads the word and mints Truth Points • RECRUIT BELIEVERS — convert your operations so they run themselves, day and night • BUILD THE NETWORK — 15 escalating operations, from Public Speakers to Rogue Satellite Jammers to the FLAT TRUTH ENGINE • STOCKPILE FOR BONUSES — every milestone of an operation doubles its output • GO OFFLINE — the movement keeps earning while your phone's in your pocket • THE GREAT AWAKENING — prestige for permanent Devotees and chase a run that lasts days, not minutes • CLASSIFIED INTEL — unlock absurd dossiers for the true faithful A DEEP, HONEST(LY SILLY) IDLE GAME A long, satisfying curve inspired by the incremental greats — early wins come fast, the endgame takes real dedication, and prestige keeps the movement going indefinitely. No account required. Play at your own pace. This is a comedy. The Earth Is Flat is a work of satire. The planet is round, gravity is real, and the moon landing happened. Any resemblance to actual convictions is entirely the joke. Please don't email us your "research." Now stop reading. The truth won't spread itself.

The Earth is Flat!'s advantage is update cadence (daily vs every 2 days). On price and in-app purchases there is nothing between them.
