The Great Barrier Reef invites you to stroll along it and meet the many inhabitants it shelters. Enter the Reef Connect Challenge game and you will dive underwater without scuba gear without experiencing discomfort. Underwater blocks with numerical values will appear in front of you. By connecting blocks with the same numbers into chains, you will get a new block with a number one higher. Complete level tasks. And they consist precisely in the appearance of a new number block in the Reef Connect Challenge.
