Factory Builder is a free browser building game where you become an industrial tycoon. You start by producing simple goods like lamp bulbs and work toward manufacturing more advanced items like flashlights.

How to play Factory Builder
Play by setting up and managing production lines, starting with basic goods and expanding into more complex products. Upgrade your technology to improve efficiency and reduce costs as you grow. The game uses idle gameplay, meaning production continues even while you are not actively playing, so you can plan changes and return to see your factory's progress.
Tips for playing Factory Builder
- Reinvest early profits into upgrades to lower production costs before expanding into new products.
- Balance adding new product lines with upgrading existing ones so your factory doesn't get spread too thin.
- Check back regularly to take advantage of the idle progress and adjust your strategy as your factory grows.
