Despite covering less than 1% of the ocean floor, coral reefs are estimated to be home to about 25% of all marine species. Unfortunately, these vibrant underwater cities are dying. Climate change and its effect of rising sea temperatures is devastating the colorful algae that give coral reefs their brilliant hues, resulting in coral bleaching. Furthermore, other threats like pollution—in its various insidious forms—and overfishing are disrupting the delicate balance of reef ecosystems.

And so, scientists from various fields, along with the researchers studying the ecological complexity and significance of the reefs, are collaborating to address the myriad challenges facing these ecosystems. Your assignment is to take command of a scientific vessel 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 saviors of the oceans. You will sail the seas, hire crew, explore the coral reef, clean the ocean sectors of any pollution, and try to accomplish as many missions as possible.

On their turn players may choose to RECHARGE or TRAVEL. If they RECHARGE, they gain the rewards from the VP track. If they TRAVEL, they may deploy Reef Balls, move their Ship, play Mission cards, and perform various actions. The game is played for a variable number of rounds. When a player has crossed the 45 VP threshold, the end of the game is triggered. After an additional round the final scoring takes place and the player with the most victory points is the winner.
