The Aquanauts slot game has a high volatility level, making wins hard to come by. But when you do, they are generally more rewarding in a game like the Aquanauts slot online than they would be in a game with a lower variance. The RTP can be adjusted between 86.90% to 96.26%, but it’s strongly recommended to set it to the highest level possible, unless you’re really in it for some big challenges. The Aquanauts online slot showcases stunning worldbuilding as gameplay is set on a frameless grid against the backdrop of a shipwreck on the ocean floor. Here you’ll come across beautiful, painterly symbols that truly immerse you in the theme. Instead of the usual card symbols like 9 to Ace, the grid is full of underwater creatures like octopi, sharks, stingrays, and jellyfish, as well as the group of divers and their special equipment. The male diver with a yellow colour scheme pays out the highest of the regular symbols at 2x for five-of-a-kind. The massive golden W is the wild symbol, which takes the place of regular symbols to help you form a winning line in the Aquanauts slot machine. It also comes with the highest payout of the entire game. Another way to rake in potential prizes is through the cascading reels mechanism that is triggered after every winning spin. While the winning symbols disappear from the grid, they are replaced by a new batch of symbols that could possibly bring you another winning combination. Every time you score another win, the multiplier increases by 1x. Scatter symbols, on the other hand, activate the free spins. Before this bonus, you’ll be taken to a prize wheel screen, which determines the number of spins you’ll get, as well as the multiplier values and modifiers.
