Sea World is a fun game that requires visual intelligence and planning skills. You need to anticipate what will happen after you remove some fish from the screen. Of course, your attention to detail is super significant in this brain game.
This game assesses your cognitive flexibility to think of innovative solutions and not fixate on old ones. You need to draw a line between fish of the same species, which are close to each other. Once you draw a line, these fish will disappear, and the fish above them will drop in their place.
