The heart of the game

Every tide opens a different island.

The sea rises and falls on a living clock. At high tide your boat can reach the deep fishing grounds. At low tide, sandbars, tide pools and cave mouths rise out of the water, and for a few minutes you can walk where you sailed a moment ago.

Fish the high tide

Sail out to rippling fishing spots and deep channels. Big fish come close to the reefs when the water is full.

Walk the low tide

Step off onto wet sand. Flip rocks, dig for razor clams, sweep a net through tide pools, find bottles with letters inside.

Read the sea

Spring tides pull the water further out than usual. Check the forecast, plan your day, and be back on your boat before the flood.

What you'll do

A small sea, full of secrets.

01

Cast into a living sea

Sail to shimmering fishing spots, charge your cast, and play the line as the fish fights back. Every island's water holds different fish, and some only bite at dusk, in the rain, or when the tide is turning.

  • Real fish species, each with its own habits
  • A field guide that fills in as you catch
  • Upgrade your rod, cooler and bait

02

Beachcomb what the sea leaves behind

When the water draws back, the shore becomes a treasure map. Look for two small holes in the sand and dig. Turn over rocks for crabs. Net the tide pools. Sell your haul at the dock, or turn it into bait for tomorrow.

  • Sandbars that only exist at low tide
  • Crab traps, drifting crates and messages in bottles
  • A tide-pool aquarium to fill with your finds

03

Face the Tide Lords

Each island has a legend: a giant fish with a name, who only shows up when the conditions are just right. They run, leap and dive in multi-stage battles. Learn their signs, wait for their tide, and bring them in.

Bring the islands back to life

Rebuild the old dock with Xiaoman the boatwright. Relight the lighthouse that has been dark for years. Reopen the research station on the coral atoll. Every restoration changes the islands and opens up new waters.

  • Restore the dock, lighthouse, station and aquarium
  • Commissions from the people of the isle
  • Six islands to explore

The story

The last tide keeper left you her boat, and a trail of letters.

Grandma Lin watched over these islands for most of her life. Now her old boat is yours, and her letters keep washing up in bottles, half-buried in sandbars, tucked into crab traps. Each one points to a place the sea only reveals at the right tide.

Follow them across six islands, and down into a sea cave that opens only at the lowest spring tide.

"Don't rush. Wait until the water settles before you cross. Before the flood, the path will quietly sink back under the sea."

— from Grandma Lin's first letter

The people of the isle

Uncle A-Hai 阿海伯

Fish market owner

"When the tide goes out, don't just sit there fishing."

Xiaoman 小满

Boatwright

"New piles are in! Listen, even the waves sound different now."

Dr. Chen 陈博士

Researcher, coral atoll station

"Interesting. Please, write down where you found it."

Grandma Lin 林婆婆

The former tide keeper, in letters only

"Put back every stone and shell you step past."

Ou the gull 小鸥

Your companion at sea

Lands on your bow, points the way, and warns you when the tide turns.

Made for your evenings

Calm when you want it. Thrilling when the sea is.

No combat

No swords, no monsters. The excitement lives in the water: a running fish, a turning tide, a storm at night.

One tide, twenty minutes

A full tide cycle takes about twenty minutes. Play one before dinner, or keep sailing all night.

Something new every day

Weather, spring and neap tides, and the people of the isle change what you'll find each time you return.

Idle mode Planned

Shrink the game into a small window and let your boat fish quietly while you work.
