How to play: The Sea Cave

Dive for treasure

Dig up every treasure before your air runs out.

Each dig uses 1 air.

Dig

Tap a sand square to dig it.

Tap the X twice to surface early. That counts as a loss.

The sonar number

A dug square shows the steps to the nearest piece still buried.

Steps go up, down, left or right, never diagonally.

The piece's own square is the last step: right next to it reads 1.

Number colours

Red 1, orange 2, yellow 3, blue 4 or more.

A number is fixed when you dig it and never changes.

So once a piece is up, older numbers may still point to it.

Gold squares

A gold square is a piece of treasure you found.

A treasure covers 2 or 3 squares in a line. Dig them all to bring it up.

The rest of it is right beside a gold square. Treasures never touch.

Two treasures

Two treasures under the sand now. Bring both up.

Sea urchins

Digging an urchin costs 3 air instead of 1.

It shows no number. Trust the sonar and dig with care.

Big treasure

A big square treasure: four pieces, 2 by 2.

Murky water

The sonar only counts 1 or 2 steps. Anything farther reads "far".

Three treasures

Deep in the cave, three treasures hide in the sand.

Air tanks

Each dive costs 1 air tank, win or lose.

Tanks refill 1 every 4 hours, up to 5. Orders and videos give more.

Win to dive deeper. Lose and you try the same dive again.

Dive prizes

A won dive pays 20 Coins, a lost one 4.

Every 5th dive adds a chest, every 10th a card pack.

The relic room

Every dive you win takes the cave deeper.

Deeper down, old relics wait: tap Bring up! to collect one.
