OCEAN: Great Barrier Reef is a family card game in which the players are marine biologists who must attempt to rebuild part of the famous coral reef Great Barrier Reef, which is located off Australia’s east coast. Over the course of the game players collect combinations of Fauna Cards which may be redeemed for Coral Reef Cards. These Coral Reef cards are then used to rebuild part of a coral reef. The player who rebuilds the best coral reef the fastest wins the game.
