About Idle Engineer Millionaire Gear

Idle Engineer Millionaire Gear throws you into a unique blend of idle tycoon gameplay and engineering simulation, where spinning gears and creating chain reactions isn’t just satisfying—it’s insanely profitable. In this highly creative idle factory management game, you don’t just tap to earn—you build, connect, and optimize.

Your goal is simple but exciting: construct a cash factory, design intricate mechanisms, and let automation and electricity power your journey to riches. 

Build a Working Gear System

Start small by spinning cogwheels manually to get your money-making machines started. As you earn cash, you’ll unlock wind-up engines to automate basic tasks, eventually connecting a powerful steam engine to run the entire factory in idle mode—even while you’re away from the game.

Tap, Stomp, and Upgrade Coins

Increase the value of your coins by tapping them quickly or placing powerful stompers along their route. Want an even bigger boost? Connect stompers together for a mega-upgrade to your coin production process.

Harness Natural and Mechanical Power

Use your engineering creativity to build a tower that captures lightning, producing electric energy that powers your cash factory. Later, teleport coins to different factory rooms using high-tech machines for processing, multiplying their value.

Chain Reactions and Advanced Engineering

Create complex gear chains, connect distant cogs, and explore how even the smallest mechanism impacts your income. The more advanced your designs, the faster and bigger your earnings.

Catch Gremlins and Build Portals

Watch out for mischievous gremlins—catching one can earn you valuable rewards! As you expand, build a portal in your basement to collect rare resources that boost your prestige during restarts, giving you massive production bonuses.

Expand and Stack Your Factory

The game lets you go vertical and horizontal—buy and stack new rooms, expanding your factory across multiple levels. Mix and match layouts to build the most efficient production empire.

Offline Progress & No Ads Required

Your machines keep working while you're offline, producing wealth without your input. Best of all—no ads required for upgrades! You can unlock everything by playing and building, with no forced interruptions.

Meet Quirky Steampunk Characters

Along your journey, get advice from colorful steampunk characters like the engineer, the sky explorer, and the eccentric millionaire. Each one helps you become a more efficient, creative, and wealthy industrial tycoon.
