A small reef with a big comeback.
Help a quiet bay become a colorful reef again. Team up with ocean creatures, restore underwater habitats, and take your little sub beyond the shallows.
How to play Coral Cove
The water is clear, but the reef is quiet. Send a ripple through the cove, gather pearls, and give a little cleaner shrimp its first home.
- Send a ripple by clicking or tapping the main play area. You can also press Space while playing.
- Spend pearls on helpers, starting with the Cleaner Shrimp. Helpers produce resources automatically.
- Use Craft, Explore, and Mastery research to choose your next improvement.
- Open Dive Log. Choose a dive plan and explore beyond the nursery. Bring back pearls and observations, then use field notes to improve your expedition program.
- Follow the story through ten chapters. Later, Fresh Tide lets you begin again with permanent ocean charms.
A world that fits your time
Helpers start with 50% offline efficiency and room for up to 12 hours of earnings. Research and permanent skills can improve those limits. Finished activities wait until you collect them.

A useful first step
Your reef earns pearls while you explore. Producers and dives work together.
