Dive into the vibrant and diverse underwater world of the Reef Color Challenge. You will explore the largest reef in the world's oceans, home to many fish and other creatures. The exploration will take the form of a block puzzle. Move the top block in a horizontal plane, placing it above exactly the same one so that it disappears, or better if there are two or more of them. The block will change and you will also find a match for it, again moving along the surface. Try to remove clock blocks to add time to the Reef Color Challenge.
