About Reef Bloom
A coral reef, yours to grow.
What is Reef Bloom?
Reef Bloom is a free browser-based ecosystem game where you build and nurture your own coral reef. Place coral, hatch fish, and watch life flourish as your underwater world grows more vibrant over time. There is no failure state — you are a steward, not a controller.
How It Works
- Place coral on a 10×10 grid to generate Bubble Energy, the in-game currency.
- Hatch fish that swim freely through your reef using boids-style AI movement.
- Grow your Harmony — biodiversity increases your reef's overall health and visual vibrancy.
- Explore biomes — travel between Coral Reef, Seagrass Basin, and Deep Twilight.
- Level up to unlock new species across Common, Rare, and Epic tiers.
Features
- 20+ coral and fish species with procedurally generated visuals
- Multiple biomes with unique species and mechanics
- Idle streak bonuses that reward stepping away
- Seasonal events, daily quests, and collectible clams
- Three save slots — your progress stays in your browser
- No accounts required, no data sent to servers
