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 10 beautifully illustrated ocean worlds. Every few correct answers reveals a new sea creature, narrated with a real conservation fact about why it matters.

10 OCEANS TO EXPLORE
Coral Reef, Tropical Lagoon, Kelp Forest, Arctic Ocean, Mangrove Nursery, Sunken Shipwreck, Open Ocean, the Deep Sea, the after-dark Midnight Trench, and the glowing Jelly Bloom. Each has 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, Lion's Mane Jelly, and more), who then joins that ocean's Sanctuary for good.

SEASONAL OCEANS AND EVENTS
Some oceans open for a month each year, free: Midnight Trench in October and Jelly Bloom in November. Step in once and it stays yours. The Daily Challenge and seasonal events like the Beach Cleanup and the Net Rescue hunt give a reason to come back every day.

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 to 4) to times tables (ages 8 and up).
- A "For Grown-Ups" progress screen shows exactly what your child is practicing and how they're doing.
- Practice one skill at a time: just adding, just subtracting, or a single times table.
- Lines up with Common Core math (Kindergarten to Grade 3) and England's EYFS to Year 4.
- Easy-read font option for children who find standard print hard going.

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.
