Manage a bustling port's traffic in Port Authority, where your decisions guide ships and prevent collisions. A 2026 indie strategy game that blends simulation with casual play.
About this game
Take control of a busy harbor. Draw routes to guide each ship to its color-matched dock. Once docked, cargo is transferred and ships set off again, meaning you'll need to manage both incoming and outgoing vessels carefully.
As traffic intensifies, every decision matters. Weave small, nimble boats between massive freighters, coordinate multiple routes at once, and keep the harbor running smoothly even as it becomes increasingly crowded.
Key Features
Draw precise routes to guide ships through busy waters to their color-matched docks.
Upgrade your harbors and fleets, and score extra points by docking ships perfectly.
Navigate 22 unique harbors inspired by real ports around the world.
Control vessels of different sizes, each with distinct speed and handling characteristics.
Minimalist, abstract visuals.
Challenge yourself and compete globally on the leaderboards.
Keep playing in Endless Mode without pressure for as long as you want.

Istanbul & Color Customization
New Map: Istanbul, TurkeyAdded Ambarlı, the big container port on Istanbul's Marmara coast. It's a row of long piers running out into the harbor, each one packed with docks.There's plenty of docking space, but the lanes between the piers are narrow, so getting big ships in and out without a jam takes some planning.Color CustomizationContainer colors are now fully customizable in the settings menu. Every container color can be set to whatever color you want, and the harbor structures (walls and inner area) can be recolored too.Read full article on Community Announcements (NFold)Patch NotesOfficial
