Every monster fights back
Each chapter ends in a giant hunt. Every boss fights the line its own way, each move is shown before it comes, and every blow lands on your ship.

Volcano Turtle
FireHawaii
Dives deep out of reach, then surfaces to breathe: reel in fast while it does, every blow hits harder.

Kraken
WaterBermuda Triangle
Slams a great arm down on the deck, blasts a torrent at your crew and grabs a sailor: shoot the arm to free them.

Coral Queen
NatureRio de Janeiro
Flings its vines across the deck and binds your crew; Nature heroes slip free.

Sea Sphinx
EarthEgypt
Pounces on the bow and turns heroes to stone with its stare.

Thunder Shark
LightningNorwegian Fjords
Sends lightning down the line, so let go or your crew is shocked, then lunges to bite.

Magma Lionfish
FireDubai
Rams the ship with flaming spines: drag to steer aside.

Starlight Manta
WaterMaldives
Leaps out of the sea and crashes a wave over the bow; the line jerks as it lands.

Karst Hydra
NatureHa Long Bay
Three heads that tow the ship away and smash the deck with a stone fist: steer after it.

Fortress Crab
EarthGreat Wall
Carries a watchtower on its back and crushes the deck with its claw.

Abyssal Leviathan
Every elementMariana Trench
The five-phase final hunt in the deep: it takes on the power of every sea, one rune after another, and lashes the deck with its tail.
The element circle
Every hero and every monster belongs to one of five elements. Hit the element you beat for more damage, and collect the Soul of each element from its monsters to raise the heroes you want.

How you hunt
Throw the harpoon
Hold to aim as a ring closes on the monster, let go to throw. Until the harpoon strikes, the monster keeps its distance and shrugs off your crew's blows.
Fight on the line
Hold to wind the winch and drag the monster into range of your crew; ease off before the worn line snaps. You have three harpoons per hunt.
Steer the ship
Drag across to follow a monster that tows you away, turn aside from a charge and keep clear of the rocks. Small monsters climb over the rail: hold the deck too.
Raise your crew
Every hero has a range of their own on deck. Level them up, raise their stars, and from 4★ awaken a second element for one of 10 elemental reactions, such as Steam, Magma or Overload.
Build your ship
In the shipyard, build up the hull, the winch and its line, and the harpoon: iron, steel, bronze, gold, then a rune harpoon whose line runs with elemental light. Equip each hero with a weapon, armour and a charm.
Come back every day
Daily and weekly missions, achievements, a daily shop with chests whose odds are shown up front, and Mine that keeps piling up while you are away.
