Factories

Factories is an idle clicker game built around the slow satisfaction of watching a small operation grow into a sprawling industrial network. You start with almost nothing — a handful of clicks, a trickle of resources — and gradually build outward from there.

The core loop is straightforward: generate resources manually at first, then reinvest them into production buildings that work on their own. Over time, automation takes over and the numbers start climbing without constant input. New factory types unlock as your wealth grows, each producing different goods and feeding into a broader economy you piece together yourself.

What makes it worth returning to is the upgrade system. Small improvements compound quickly, and deciding where to spend resources next gives the game a light strategic layer beneath the clicking. Nothing demands urgent attention, making it a decent option for idle sessions between other things.
