Coral reefs cover less than one per cent of the ocean floor, yet support around 25 per cent of all marine life. Modern Community is highlighting the importance of protecting this essential ecosystem with its latest limited-time challenge.

What we love: Familiar match-3 levels offer a new, meaningful theme of reef restoration. The reefs start as bleached – something that’s happening in the real world, due to global warming – and gradually transform from recovery to thriving. The players with the most reefs restored will earn in-game rewards.

Don’t miss: You get to take part for just 30 minutes a day, to ensure a truly focused experience. Make it count!
