Island Rail: Cozy Mail Routes

Carry a little kindness to the next island.

A letter is waiting to be delivered. An island is waiting to be connected. Pack your mailbag and join a cat conductor and a squirrel companion on a cozy route-puzzle journey through meadows, coastlines, snowy fields and seas of clouds.

DRAW A ROUTE AND SET OFF
Tap or drag through neighboring squares, visit stops in order and connect the finish. Tracks, bridge materials and travel range are limited. Work around tunnels, one-way passes, key gates and tidal mechanisms. Undo, redraw or ask for a next-step hint as you find your way.

120 PUZZLES BY LAND, SEA AND SKY
Travel through twelve story chapters with 30 levels each for trains, ships, planes and rafts. Transfer at ports, airports and docks, learning new route rules and mechanisms along the way.

TAKE THE SCENIC ROUTE WITH A FRIEND
Squirrels, beavers, foxes, otters and other animal companions have favorite sights. Bring them past the places they love to build friendship and unlock little stories, postcards, quotes and carriage flags. Arrival, stars and sightseeing goals can be completed over separate runs.

TURN A POSTCARD OVER TO READ A LETTER
Levels 3, 6 and 10 in each chapter unlock a page of a 36-page illustrated story. Turn a postcard over to read a letter home, then finish a chapter to open a companion's reply. Revisit unlocked story animations in your collection.

VISIT ANOTHER ISLAND TOMORROW
Today's Island offers a daily route puzzle. Gather chapter stars to open Star Challenges and collect golden postmarks. Your travel journal records routes and sights, while the achievement wall keeps track of your progress.

TRAVEL AT YOUR OWN PACE
Pause a journey or choose 0.5x, 1x or 2x speed. Zoom in, follow the vehicle with the camera, or enable reduced motion. Switch between Traditional Chinese, Simplified Chinese and English.

Core gameplay on Android works offline and requires no account. Progress is stored on your device, with no cross-device cloud sync. Clearing app data removes your save. Local reminders are off by default and can be enabled in Settings.
