How to Play

Factory Builder: Mastering the line

Use WASD or tap to navigate your factory floor and interact with machines. You need to identify which raw materials feed into your specific products. The Factory Builder controls feel stiff during that first setup, so take your time placing belts. If you misplace a conveyor, your output drops to zero.

How to play Factory Builder efficiently

Focus on upgrading your transport capacity before dumping cash into new tech. If you ignore the shipping side, your goods just pile up on the floor. Common mistake: building too many machines without enough vans to clear them. Once you master this, you can start optimizing for speed and cost-cutting.

Who Should Play Factory Builder?

You want a management game that respects your time but lets you obsess over spreadsheets? This is your jam. It is perfect if you like watching numbers climb while you tweak layouts, though the camera can feel a bit cramped when your factory grows too wide.
