Supply lines

A supply line sends spare coffee, or any other resource, from one city to your other cities every few hours, using your own transports. It runs from a Shipping Office.

• It sends only what is above the amount you keep at home.
• It fills each city towards a target and gives most to the city furthest below it.
• It counts what is already at sea, so it never sends the same shortfall twice.
• It never sends more than a city's Storehouse can hold, so nothing it sends is lost.
• A city that would get less than 100 is skipped that run.

• Your empire runs one coffee line free, from any Shipping Office.
• Every other line costs 250 platinum for 30 days, and can carry wood, stone, glass, coffee or mana.
• Press Renew on a paid line to add 30 days. Nothing renews by itself.
• A paid line that runs out stops and keeps its settings. Renew it and it starts again.
• A Shipping Office runs 1 paid line at level 1, 2 at level 2 and 3 at level 3. Raise it to buy another. Your free coffee line never counts against that.
• You can run up to 10 paid lines at once across your empire. All of an office's lines share its daily limit.

A line reads as one sentence, and each setting in it is a dropdown.

How often

Every 1, 2, 4, 8, 12 or 24 hours.

Destinations

All your cities, including ones you found later, or one city.

Keep at home

For coffee, hours of this city's own pouring, 12 to start. For anything else, a number of units.

Target

For coffee, hours of each city's pouring, 12 to start. For anything else, a share of each city's Storehouse.

Most ships per run

So a line never takes your whole fleet.

On the Shipping Office page you can also leave a number of ships idle for everything else. Lines never use those.

• The office's level: 2,000 a day at level 1, and 1,000 more for each level after. A shipment you recall still counts.
• Idle ships. When none are free, the line waits and runs as soon as one lands.
• A run that finds nothing to send, or nobody short, waits a full interval.
• If the server was down when a run was due, it runs once when it is back, not once for every run it missed.

A supply shipment is an ordinary shipment. It shows on the Port's At sea list and in the office's Recent shipments, and you can recall it like any other.

• When a Coffee Shop's first level finishes and you have never set its rate, it starts at half of what it can pour.
• A Coffee Shop set to nothing, in a city with less than an hour of coffee at its full rate, counts as wanting its full rate. A coffee line fills it to that, and sets the shop to its full rate when it sends.
• Change the rate whenever you like. A shop set to nothing over more coffee than that is left alone.
