In Benthic Grove, you'll build your own reef ecosystem, adding animals from different groups, from corals and crustaceans to fish and mammals. On each turn, you choose an action: draw cards into your hand, play animal cards into the reef, remove pollution, or secure end-game bonus points. The action you choose determines which animals you can activate that turn and which resources all players will collect simultaneously. But be careful! Producing too much algae or plankton can pollute your reef. Points are earned by the animals played, conditions met by corals, end-game bonuses, and activating animals' abilities. The game ends when a player fills all spaces in their reef or attracts one of the available Megafauna. The player with the most points wins!
