Quite calmly, you can explore the underwater world in a virtual space and for this you do not need special equipment, which, by the way, is not cheap. In addition, to dive to the ocean floor, you need to swim some distance, which means you need at least some kind of vessel. All of this is not needed in Sea World. Just open the game on any device and in front of you is a multi-colored sea world of fish, seahorses, stars and other inhabitants of the sea. Make long chains, they must contain at least three identical fish, connect them and the scale on the left will be constantly filled in Sea World.
