Nexus Tycoon is a free idle business tycoon game right in your browser — no download, no signup. Start with a tiny data node, tap to earn, then reinvest in the shop to buy more businesses and unlock new ones. Hire managers so everything runs automatically — even while you're away, thanks to offline earnings. When growth slows, cash out to investors for a permanent multiplier and start a faster run. How big can your Nexus empire get?
