About the game

A narrow strip of ocean on the edge of your desktop, with a dock, some water going down into the dark, and an old man who fishes whether you are watching or not. You share the harbour with up to fifty real players.

Your clock is the game's clockDawn at your desk is dawn on the bay. Night species only bite in your real night, the moon follows the real lunar calendar, and the Storm Belt can only be fished in the rain.
Forty legendaries, none of them luckEvery legendary is gated on being somewhere, at some time, with the right gear. You read the rumour, work out what it means, and go and be there.
Click if you want toGrab the bite and win the catch bar for double pay and a heavier fish. Miss it and the fish still lands at its honest price.
A harbour of real playersUp to fifty players share your harbour. Their boats cross your strip, the Night Market moves on what everyone landed today, and eight all-time leaderboards keep score.
Still there in month fourSixty levels, three perk lines, five mastery ranks on all 120 species, twelve relics, 480 field studies and sixteen seasonal almanac species.
Quiet by designUnder 1% CPU, no pop-ups and no daily-reward guilt. Close the window and the old man dozes in your system tray.
