Spaceport Tycoon is a free iPhone and iPad game that lets people who enjoy idle builders start with a small launch site and grow it into a spaceport that keeps expanding. You upgrade launch pads, fuel and control facilities, follow expansion goals and decide what to improve next.

Build a spaceport one upgrade at a time

Rockets launch on their own from every pad you build and pay Credits when they land. Each launch needs a pad, fuel from the Fuel Farm and a slot from the Control Tower, and the slowest of the three sets your income. The Dashboard shows which one is holding the port back, so the real decision is where to invest next. You follow expansion goals, open new facilities and manage the Credits, Supplies and Housing a growing port needs.

Explore trips bring back Moon Rocks, and more are earned free as the port grows. Moon Rocks can be traded for Credits, cover missing Supplies when building, finish a build early or add Housing. The port keeps earning a reduced share of Credits while you are away, for up to four hours per absence, ready to collect when you return.

Spaceport Tycoon is a single-player game. There is no account to create, gameplay works offline and your port is saved on your device. It is free to download and has no ads; optional Moon Rock packs in fixed quantities are sold through Apple’s in-app purchase and are not subscriptions.

Spaceport Tycoon is available today for iPhone and iPad on the Apple App Store.
