Grow a small workshop into a factory empire across five eras
Idle Factory Tycoon is an offline idle tycoon game by Rui Codex for Android phones and tablets, with an iPhone and iPad version on the App Store. Players build and upgrade 50 factories across five eras, hire managers and prestige for permanent upgrades. It is free to download, with ads and optional in-app purchases.
Scroll sideways or use the arrow keys.
From the Small Workshop and Assembly Line to the Fusion Reactor, Dyson Sphere and The Omniforge, each with its own machine and product.
Factories keep working while you are away: up to 24 hours of earnings, or 72 hours with the Extended Shift blueprint.
Assign a manager to every factory and choose efficiency, thrift or night shift, then change it whenever you like.
Prestige for Blueprints and a permanent upgrade tree, then unlock eight patents in the Patent Office.
Rankings count only this week's earnings, so newcomers can win prizes too. The league needs an internet connection.
Daily rewards and missions, weekly challenges, golden crates, weekend Overtime events and 39 achievements.
No banners, at most three full-screen ads a day at natural breaks, and none for players with Remove Ads, VIP or the Tycoon Club.
You start with a Small Workshop and grow it into a production empire that runs from the Industrial Age through Advanced Tech, Quantum Realm and Cosmic Dominion to the Transcendent era. Every factory has its own machine, product and conveyor belt. Buy levels to raise output, tap a machine to rush it, and hit level milestones that multiply production by 1.5. The numbers climb quickly at first, then the game asks you to plan where each coin goes.
The factories keep producing while you are away. When you return, the game pays up to 24 hours of offline earnings, or up to 72 hours with the Extended Shift blueprint. Each factory can have a manager, and every manager is set to one of three specialties: efficiency, thrift or night shift. You can switch a specialty whenever your strategy changes, so the factory floor adapts to how often you play.
Progress has two prestige layers. Starting over pays Blueprints for a permanent upgrade tree, and the Patent Office adds a second layer with eight patents. A Product Collection keeps every milestone you have reached, so a reset never erases your record. Daily missions, weekly challenges, weekend Overtime events, 39 achievements and nine Tycoon titles give each session a target, and a weekly league ranks only what you earn that week, so new players can compete.
Ads follow published rules: no banner ads, at most three short full-screen ads a day, only at natural breaks and never in the first ten minutes. Reward videos are always the player's choice, and Remove Ads, VIP or the Tycoon Club turn full-screen ads off entirely. Everything can be earned by playing, purchases are optional, and a cloud backup with a transfer code moves progress to a new device. Feedback can be sent to the developers from inside the game.
Players who enjoy incremental and tycoon games that move forward in short sessions and keep earning while the phone is locked.
