Your ⭐ HQ places orders for goods, and new 🏢 customer DCs will start ordering too as you play. Each factory turns two ingredients into its product — the bakery 🍞 needs wheat and water, the smelter 🔩 turns ore and coal into steel for the car factory 🚗. Some chains run deeper and share ingredients: the robot factory 🤖 needs a circuit board 🔌 (itself made from wire 🧵 and electronics 💾) plus the same steel your cars use. Every raw material feeds more than one recipe — that coal pit is wanted by the smelter, the tyre plant 🛞 and the battery plant 🔋 at once — so running several chains means planting more of the suppliers you already have, not just new ones. Your trucks do the hauling — but only where roads exist.
