Coral

About Coral, from BoardGameGeek:

In Coral, players develop a coral reef together, whilst vying to position their own species closest to the top, where they can soak up the life-giving sunlight. Together - as much as against one another - you'll build a unique, magnificent 3D structure out of gorgeous wooden pieces. This represents a coral reef growing and living in a complex, competitive harmony. Move around the table to find the best spots to grow your species, whilst blocking your opponents! At the end of the game, the player with the most pieces visible from above the reef is the winner. --- Coral includes a bespoke solo puzzle mode and several multiplayer game modes, for exciting games for 1 to 4 players. -description from the publisher
