About

INTEREST.EXE

Features
Read full description

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.
