The bonus features in Aquatic Treasures are not exactly revolutionary, to put it mildly. You can land a dolphin wild on the 3 middle reels, and it will expand to cover the full reel whenever it appears. If you land more than one wild adjacently on the reels, they will combine into a bigger wild. This makes no difference except for visually, and the only thing that’s a bit unusual is the fact that the wilds will also substitute for scatter symbols in this game.
