Five thousand years of history, working for you. It starts with mud-brick huts in Sumer. Twenty-nine ages later you're running the Han Dynasty. And history isn't finished yet. Each age feeds the next. Grain from Sumer becomes gold in Akkad, becomes monuments in Egypt, becomes legions in Rome. SUMMON THE GREATS Gilgamesh. Cleopatra. Hammurabi. Ramses II. 115 heroes who double production, quicken cycles, or run an age for you. Legendaries hold sway over several at once. WALK AWAY. COME BACK RICHER. Give an age a manager and it keeps working with the app closed. Return to a fortune, reinvest in a minute, get on with your day. EVENTS Fresh empires with their own currencies and leaderboards. Climb, claim heroes, keep them for good.
INTEREST.EXE

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.
