Dive deep, dodge the sharks, and find the buried treasure!
Filling the ocean…
Press M (or tap the map) to close. Caves are dark, bring a light!
Goal: The pirate treasure is buried in one of the four dark caves. Find the right cave, then dig at the X!
Clues: Messages in bottles tell you which caves do not have the treasure. Digging in a wrong cave also crosses it off.
It's dark in the caves! Find a diver's lantern 🔦 (the sunken ship has one) or flares 🧨 (red crates by the cave doors). Throw a flare with F, it lights up the cave for everybody and scares sharks.
Sharks 🦈 chase you if they spot you. A bite costs a ❤️. Lose them all and you pop back at Reef Home, the glowing circle in the middle, where sharks can't go.
