Harbor Line Control

Harbor Line Control is a harbor-traffic puzzle. You draw safe passages so every ship reaches its matching numbered berth. Read the water, keep hulls from colliding, and leave room for each vessel as traffic builds.

Play 100 levels across five harbors: Sunny Marina, Industrial Bay, Island Channel, Storm Harbor, and Midnight Port. Completing a level opens the next. Replay any finished level to improve its Harbor Medals and score. Pause or restart a run at any time, then continue from the same journey.

Open the Ship Library to study vessel types, speeds, hull sizes, and priority ships that earn extra docking points. Harbor Records collect your safe docks, perfect runs, and best scores. Achievements track completed levels, collections, perfect runs, and finished harbors. Statistics show routes assigned, collisions, restarts, best streak, and time played.

How to Play walks you through the field guide and a first guided level. Music, sound, and visual effects can be switched in Settings. Score rewards safe docks, route efficiency, and finishing under par, then awards one to three Harbor Medals.
