Zinc Ledge

Zinc Ledge puts you in charge of a hot-dip galvanizing workshop. Steel parts arrive as orders: pipes, bolts and plates, each with a target zinc coating thickness.

Hold CHARGE to drive current through the bath. Coating only builds above the minimum amps, but push past the burn line and the coat blisters. Keep the needle inside the green band on the ammeter while the thickness gauge climbs toward the target range.

Parts heat unevenly as they soak. Watch the heat bar and FLIP the workpiece before plating slows and burn risk rises. Every job heats the bath and drags in impurities, so skim and cool it with MAINTAIN or your plating rate suffers.

Hoist the part when the gauge sits in the target band. Accuracy plus low burn damage decides your rating and your pay. Spend coins in the shop on six permanent upgrades: Precision Ammeter, Coolant Loop, Zinc Filter, Alloy Anodes, Auto Flipper and Flux Coat. Each one changes how the line really behaves.

Simple to learn, tense to master. How long can you keep the line running clean?
