ECO: Coral Reef how to play

About ECO: Coral Reef, from BoardGameGeek:

ECO: Coral Reef is an innovative and fast strategic game consisting of planning and placing variant tiles that create a colorful mosaic of marine life. In this game, the participants will collect and place pictures tiles to create a shared image of a vibrant coral reef. Each player's personal and hidden interest, depending on their goals, reshapes and changes the map. What creates challenges and difficulties for the players also creates new opportunities for them. While matching species and completing missions, each player advances his sea turtle towards the water line and to the victory. The abstract gameplay feels like a combination of Dominoes & Chess. -description from the publisher
