A·1Modes

Three ways to fight

Every mode is played against real opponents; bots fill empty seats when the sea is quiet.

Classic

10×10 · 10 ships · no touching

The sea duel everybody knows, sharpened for online play: clean rules, quick turns and nowhere to hide.

Extended

12×12 · energy & abilities

Captain abilities change the rhythm of every turn: scout with sonar, launch torpedoes, cover your fleet with smoke.

Survival

4 players · storm

Simultaneous turns on one shrinking sea while the storm closes in. Last fleet afloat wins.

B·6Abilities

Cooldown 3

Maneuver

Survival

Slides an undamaged ship one cell up, down, left or right.

Energy 3
Cooldown 4
Carrier: Any ship

Energy starts at 0 and grows by 1 every turn and by 1 more for each hit, up to 5.
Cooldown is how many of your own turns an ability needs before you can use it again.
You bring 3 abilities into every Extended and Survival battle, ranked or casual, and only those can be used.
Smoke is a free action: add it to any shot or other move in the same turn and pay only its energy.
An ability works while a ship of its carrier class is afloat. Maneuver can move any undamaged ship.
You start with Salvo, Sonar, Repair. Unlocked in the Harbor: Smoke (Radar station 2), Torpedo (Arsenal 2), Maneuver (Arsenal 3).

E·7Harbor

Your harbor, your fleet

Between battles the war goes on at home.

Unlock hero ships, achievements, titles and rewards.
Finish daily and seasonal goals for pearls and other prizes.

F·3Harbor

Six buildings

Six buildings decide what your fleet can do. Upgrade them between battles.

Shipyard

The heart of the harbor: it caps ship levels and unlocks new classes and hulls.

10 levels. Sets the highest level your ships can reach. Level 3: submarine. Later levels: new hulls.

Radar station

Intelligence: new scouting abilities and an early look at the enemy.

4 levels. Level 2: Smoke. Level 3: enemy fleet visible before Expedition battles. Level 4: wider sonar area.

Arsenal

Attack abilities for your loadout and faster reloads.

4 levels. Level 2: Torpedo. Level 3: Maneuver. Level 4: Salvo and Torpedo reload one turn faster.

Dry dock

Makes repair tokens every day and repairs ships for free in battle.

5 levels. Repair tokens: 4 to 12 a day. From level 2: free repairs in battle, up to 3 per battle.

Naval academy

More ability slots and energy in Expedition, Gauntlet and Custom.

4 levels. Levels 1 and 2: 4 and 5 ability slots. Level 3: +1 starting energy. Level 4: +1 maximum energy.

Port

Merchant trade brings gold every hour. Collect it before the storage fills up.

8 levels. Gold every hour, from 10 at the start to 33 at the top, collected from the storage.

Builders and timers

Two builders work for free and a third can be hired for pearls. A builder handles one building or ship at a time, shared between harbor and fleet.
Upgrades take from a minute to a full day at the top levels. Wait, or spend pearls to finish early.
Upgrades cost gold and steel earned in battles and daily goals, and the Shipyard must be high enough first.

G·8Fleet

Five ship classes

Every class carries one ability. In Expedition, Gauntlet, Custom your ship levels count; in ranked and casual battles everyone sails with equal ships, so skill decides.
