About this game

Dive into Reef Rescue — a friendly ocean-math adventure where every correct answer cleans up a little more of the sea and brings a rescued creature home.

LEARN BY RESCUING
Kids solve age-appropriate math (counting by tapping, "how many?", addition/subtraction, or multiplication/division — you pick the level) to clear trash from 8 beautifully illustrated ocean worlds. Every few correct answers reveals a new sea creature, narrated with a real conservation fact about why it matters.

8 OCEANS TO EXPLORE
Coral Reef, Tropical Lagoon, Kelp Forest, Arctic Ocean, Mangrove Nursery, Sunken Shipwreck, Open Ocean, and the Deep Sea — each with its own creatures, math level, and fully voiced host.

BUILD A LIVING SANCTUARY
Coins earned from correct answers fund a wild-habitat Sanctuary for each ocean — plant real habitat pieces (coral, kelp, glacial rock, driftwood...) and watch rescued wildlife swim home as the reef heals. Every single piece comes with a real fact about how it helps ocean life.

MEET THE LEGENDARIES
Clear an entire ocean's worth of trash to trigger "Big Rescue" — a tougher math challenge that frees a rare legendary creature (Whale Shark, Blue Whale, Greenland Shark, and more), who then joins that ocean's Sanctuary for good.

BUILT FOR FAMILIES
- No ads. Ever.
- No accounts, no sign-in, no chat, no way for a child to contact anyone.
- Every purchase is locked behind a parent-only math check.
- Fully voiced and captioned — great for early readers.
- Five math levels that grow with your child — from first counting (ages 2-4) to times tables (ages 10+).
- A "For Grown-Ups" progress screen shows exactly what your child is practicing and how they're doing.

Coral Reef and Tropical Lagoon are free to play in full. Additional oceans are available individually or as a one-time Explorer Pass.

Reef Rescue is a conservation game at heart: nothing is ever "caught" or "owned" — every rescued animal returns to its restored wild home, and every fact is real marine biology, kid-tested and kid-approved.
