Description by Mehmet Efe Aytas Written by the developer, not by AppBrain. Click to read.
Every shipment has a story. Your stamp decides what happens next.

Take your place at a customs desk in GREYPORT, a fictional port in 1986. Compare manifests, permits and invoices. Scan cargo, weigh shipments and question visitors before approving, holding or confiscating goods.

People remember your decisions. The stories of three returning characters unfold across the first ten shifts, with later visits shaped by earlier rulings, evidence and bribes. Letters, radio reports and newspapers bring consequences back to your desk.

Your shift follows you home. Manage family needs, fatigue and a monthly household budget. Improve your customs post with six upgrades, choose from three difficulty levels and learn the tools through a hands-on tutorial. Original ambient music sets the mood.

The campaign spans 52 in-game weeks and six endings. Play the first five in-game weeks free. A one-time Full Campaign purchase unlocks weeks 6–52 and removes interstitial ads.

The optional monthly Harbor Supporter subscription adds 10% to earned weekly base salary and removes interstitial ads while active. It does not unlock the campaign. Optional cosmetic packs change colors or stamp decorations without changing gameplay. Rewarded ads are optional.

Core play works offline. Purchases and ads require internet access. Progress is saved on your device.
