Maritime nations share one warming ocean. Get rich from it, fight over it, or save it. If the sea dies, everyone loses.
Goal: The first nation to hold 10 ports wins. After 20 minutes the target drops to 9. Found ports on empty coasts or capture rivals' ports. If the ocean collapses, everyone loses.
How to play
Race
Gold crates from shipwrecks are scattered across the sea. The first ship to reach one keeps the gold. Rich shoals pay double for a short time.
Seas
Play on real coastlines: the Caribbean, the Aegean, the North Sea, the Grand Banks and six more, or on invented islands.
Harbour
Tap water beside an island to found your first port. Your waters reach about 13 leagues from each port.
Fish
Trawlers earn gold by fishing wherever they're anchored. Each patch of sea shows its fish stock, which regrows over time. Overfish it and it collapses. Select a trawler to see the full fish map.
Warm
Every catch warms the sea. Warmer water slows regrowth, bleaches reefs and brings storms. Wardens restore stocks and can calm and tame krakens.
Command
Move the map with WASD or the arrow keys, zoom with the scroll wheel or +/−. Tap a ship to select it, then tap water to sail or an enemy to attack. Fog hides whatever your ships and ports can't see.
Mines
Press Mine, then tap water in your waters or near your ships. Only you can see your mines. Enemy ships at war with you take heavy damage if they touch one. Sweepers reveal enemy mines nearby and defuse any they sail over.
Capture
At war, select warships and tap an enemy port. A ring shows capture progress. When its hull reaches 0, the port and its waters become yours. Ports and ships near your ports repair when out of combat.
Treat
Make peace, sign trade deals or declare war. Fishing in another nation's waters sours relations.
