Miners (⛏️) go on the orange/gray ore patches and dig ore out of the ground.
Belts (➡️) carry items. Scroll to rotate the ghost before placing, or click-drag to lay a whole line of belts that face the way you drag. Right-click rotates anything already placed.
Furnaces (🔥) smelt ore into plates. Assemblers (⚙️) craft wire, gears, and circuits — click one with the assembler tool to switch recipes.
Feed finished goods into the green delivery hub (📦) to fill the shipment orders on the right. Fill all 6 to win.
Tip: a miner facing a belt facing a furnace facing a belt facing a hub is your first production line. Chain from there.
