The street outside your door is open water.

Sea Legs is a trading game played outdoors, on foot. It charts the real streets around your home as an uncharted sea, and your ship moves only when you walk.

Free to play. Location required. Best used at walking pace, outside, with the sky overhead.

The chart, a few hundred meters from somebody's front door. The pale water has been walked. Everything darker is fog, and it stays fog until a person goes there.

A table of equivalents

Your first GPS fix founds a Home Port. Everything after that is a translation.

The world is generated from the real walkable path network around that one origin. None of the pairs below are decoration. Each one is a rule the game actually runs on.

The street outside your door: Open water
A junction on a footpath: An island, with a dock you can stand on
Ground you have never walked: Fog, until you walk it
Four hundred steps to the shops: A trading run with a loaded hold
Standing still: A ship at anchor
A letter of passage to a friend: A shipmate in your archipelago, walking your streets

Location, plainly

Sea Legs needs to know where you are. That is the game, not a caveat.

A walking game with no location is a menu. Here is the whole of what the app does with it, in the order it happens.

While you play: Your position moves your ship. It is the only control the game has, in the same way a maps app uses GPS.
Screen locked: Background sailing is optional and off until you switch it on. It shows a notification the entire time it runs, and that notification stops it.
When you are not playing: Nothing. With background sailing switched off, closing the app ends the voyage until you open it again.
Shipmates: Friends in your world see your sail only if you turn on sharing yourself.
Accounts: Optional. Apple, Google, or email, and only so a captain survives a new phone.
Ads: Optional rewarded video, on port screens only. Never required to make progress, never dropped into the middle of a voyage.

The full detail is in the Privacy Policy and the plain-language Data Policy.

Ashore

Ports have opinions, and they notice you.

Every island's dock sits on a path a person can walk to. Come ashore and there is a market, a shipyard, a bank, a tavern, and a warehouse.

Each port keeps a permanent character: one glutted with fish, the next desperate for silk. Prices drift by the hour and they respond to trade. Flood a small harbor with pearls and watch the price sink under your own boots. The fortune is in the spread, and the spread is a walk away.

The career

From a dinghy to a Man of War, at three miles an hour.

You begin shipwrecked, with an empty hold and a dinghy. Thirteen hulls stand between that and a Man of War, with refits along the way. Hire a navigator who sees further, a cartographer who keeps your charts from fogging over again, a gunner who halves the price of cannon. Take a loan you probably should not.

The sea does not care about you. Pirates give chase, and you outrun them, out-gun them, or strike your colors and pay. Storms open your hull. Debt compounds. A career can end, and one that ends is memorialized in the Hall of Fame with the score it earned.

Send a letter of passage and a friend sails your archipelago: the same islands, the same ports, the same prices, walking the same real streets, with their sail on your chart.

The rest of the chart is fog. It clears at walking pace.
