Seagrass

From BoardGameGeek:

In Seagrass, players take on the role of marine naturalists, exploring the many reefs and colonies of creatures that thrive among these expanding and diverse “rainforests of the sea.” Seagrass is an approachable strategy game with surprising depth and layered interaction. On your turn, simply expand a colony of aquatic creatures or expand a reef. Your colonies score you more points the bigger they get, and they help you compete for majorities around reefs. Expanding reefs will increase their point value and help you replenish your hand of tiles, but expanding a reef will also make it a more juicy target for your opponents! Playing out multiple tiles of the same type will grant powerful turns, but spreading out your plays will allow you to score the same colonies more times! Decisions are a tricky strategic balance in this underwater ecosystem. Seagrass is the next title in Bitewing Game's Crown Jewel Selection. The game is an evolution of Trevor Benjamin and Brett J. Gilbert's Maya, introducing many innovations by: Providing two game boards featuring tight interaction Introducing special creature tiles with powerful abilities Focusing the end-game trigger to be more exciting and impactful Hiding and balancing the scoring for a more tense competition Creating tough trade-offs with the new Discovery expansion Broadening the appeal and approachability with stunning aquatic illustrations by Alisha Giroux -description from the publisher
