Learn in 60 Seconds. Three simple steps happen on every turn: 1. Draw 2 Cards or Play a Card, 2. Play an Ocean, 3. Play Species and Build Combos. Draw or Play, Score Points, Win the Game. Quick Rules: What is an Ocean? Oceans are the foundation of your reef. What are Star Abilities? Some cards have Star Abilities that trigger when you play the card and help you build bigger turns and stronger combos. How does scoring work? Scoring comes from playing cards and combining cards, using Star Abilities, and following strong strategies. What ends the game? The game ends when someone draws the End Game card, which is shuffled somewhere in the bottom 15 cards of the deck. After the End Game card is drawn, every player gets one more turn. Tip: Plan ahead, stay flexible, and combine your cards to score big.
