About the Coral Reef recall game
Coral reefs are underwater cities — busier than any high street and twice as colourful. Dive in among the clownfish, octopuses and sea turtles for the brightest matching on the site.
Did you know?
- Corals look like plants but are actually colonies of tiny animals.
- Coral reefs cover less than 1% of the ocean floor but support about a quarter of all marine life.

- An octopus has three hearts and blue blood.
Frequently asked questions
How does the Coral Reef recall game work?
All the coral reef tiles are shown face up for a few seconds — memorise the layout. They then hide, and the game asks for each one in turn ("Where was the Coral?"). Click the right spot to reveal it; wrong clicks count as misses.
What are the difficulty levels?
Quick is 6 tiles with 6 seconds of study time, Standard is 9 tiles with 8 seconds, and Full Deck lays out all 12 tiles with 10 seconds. Your best first-try score is saved for each level.
Is it free?
Completely free, no signup, nothing to install. Progress is saved privately on your device.
