Despite coral reefs covering less than 1% of the ocean floor, they are estimated to be home to approximately 25% of all marine species. Unfortunately, these colorful underwater cities are dying. Climate change and the resulting rising water temperatures are destroying the colorful algae that give coral reefs their brilliant hues, resulting in coral bleaching. In addition, other threats such as pollution in its many insidious forms and overfishing disrupt the delicate balance of reef ecosystems.

That's why scientists from various disciplines, along with researchers studying the ecological complexity and importance of the reefs, are working together to address the many challenges these ecosystems face. Your assignment is to command a scientific ship and embark on a journey of reef conservation. Hire the best crew, clean the ocean and restore the reefs to their former glory.

During the game, players take on the role of researchers and rescuers of the oceans. You will sail the seas, hire crew members, explore the coral reef, rid the ocean parts of pollution and try to complete as many missions as possible.

During their turn, players can choose to charge or travel. When they load up, they receive the rewards from the VP track. As they travel, they can deploy Reef Balls, move their ship, play mission cards and perform various actions. The game is played over a variable number of rounds. When a player exceeds the 45 VP threshold, the end of the game is initiated. After an additional round, the final scoring takes place and the player with the most victory points wins.
