## What is Harbor Letters?

Small islands. A boat full of letters.

Harbor Letters is a route puzzle about collecting every island's letter and returning to the post office. Tap connected islands to sail, and choose the order of your deliveries. A longer route still counts as a delivery; finding the shortest route is an optional stamp challenge.

72 routes across six regions
Sail from Paper Harbor to Windward Bay, Tideclock Cove, Lantern Cape, Faraway Post and Blue Archipelago. Learn one-way channels, three tide states, waiting, tide-changing lighthouses and express channels through short, playable lessons. Complete routes to collect six illustrated story postcards.

Take your time
Hints suggest a valid next move from your current position, and undo is always free. There are no lives or timers. Turn on Free exploration in Settings to choose any route without changing your earned progress.

Today's route
A daily route remixes a bundled chart using your device's local date. A voyage already in progress stays with you after midnight. There are no online rankings or login streaks to maintain.

A journey you can return to
The core game works offline and saves an unfinished voyage automatically. Keep a progress backup code to restore or merge completion records. Choose Korean, English or Japanese, larger text, reduced motion, sound and haptic preferences.

Ads and purchases
After the first 12 tutorial routes, an occasional interstitial may appear when you leave the results screen after completing several new routes. Ads do not interrupt a voyage or appear on the daily route. An optional one-time purchase removes all ads. Every route, hint and undo is free without purchase. Ads, purchases and restoration may require an internet connection.

No account or personal-letter entry is required. The letters and postcards are original fictional content. Keep a progress backup before deleting the app or changing devices.
