Coral Fragger

Merge corals, unlock 93 species, and let the Foxface rabbitfish tidy your reef. A relaxing underwater idle game for minutes or hours.

Coral Fragger is a relaxing idle-merge game set on a living coral reef. Drag corals together to merge them into rarer species, watch your reef grow on its own, and restore the ocean one fragment at a time.

MERGE & GROW Drop matching corals onto each other to discover higher, more valuable species. With 93 corals to collect, every merge brings you closer to completing your catalogue. Leave the game and your reef keeps producing — return to a bigger, brighter ocean.

RESTORE & PRESTIGE When your reef is thriving, restore it to start fresh with powerful permanent bonuses. Each restoration deepens the ecosystem and pushes you further than before.

BUILD YOUR ECOSYSTEM Unlock and upgrade 8 reef buildings — from Solar Water Heaters and Plankton Incubators to the Quantum Reef Scanner. Each one speeds up spawning, boosts production, extends combo windows, and more across three tiers of depth.

KEEP IT TIDY Low-level corals can clutter the board and block your merges. Send the Foxface rabbitfish to sweep through and graze them down — clearing space while earning biomass and a little extra.

RELAXING BY DESIGN A calm, underwater soundscape, gentle animations, and no pressure. Play actively with satisfying combos, or let it idle in the background.
