Aquanauts slot is a team effort between Alchemy Gaming and Microgaming. The theme of the slot unfolds as a bunch of aquanauts explore the ocean depths for new marine species.

Some scientists say that we know more about space than our oceans. After all, we haven’t even explored two-thirds of our oceans yet. That’s a shame really, who knows we might just stumble across a megalodon shark.

If you’re up for an adventure that takes you to the depths of the ocean floor, book a ticket now. There are plenty of Free Spins, Rolling Reels and Echo Spins to explore.

The action of the Aquanauts slot plays out on a 5×5 grid with up to 3,125 ways to win. More importantly, the jackpot you’ll be playing for is a whopper of 50,000x your stake. But, a big jackpot also screams “I’m volatile”.

So much so, the Whizz team rates it a 10’er. Bets per spin come in at $0.30 up to a maximum of $21. You’re looking at a maximum cash prize of $1 million.

Game information













Aquanauts slot


For such a volatile slot the RTP of 96.26% is quite good. However, there are RTP ranges of 92.15% and 86.90% that drop all the way to the Mariana Trench.

If you want the best shake only play the slot at SlotV Casino. Incidentally, it’s the best EU online casino for players from the UK and Europe.



The symbols on the reels are 10 in total. They’re a mix between low-value card suits and marine life. The top symbols are treasure chests, submarines, wild, and humans.

The top card symbol pays 0.93x the stake whilst the premium pays 6.67x for 5. The wild does the usual substitution duty when it replaces symbols adjacent to it.

Aquanauts Slot Bonus Rounds

Rolling Reels

The Cascading or the Rolling Reels feature triggers on any random spin. That’s to say when you land a bunch of matching symbols. The winning symbols disappear from the grid and new ones replace them.

As long as matching symbols keep on appearing the process keeps on repeating itself. Better still, the Rolling Reels feature increases the win multiplier by 1x with each tumble.

Echo Spins

EU players that play the slots online for real money can initiate the Echo Spins feature on a random spin. You can benefit from wilds, high or low-value symbols for a win.

Free Spins

When 3 scatters land they trigger 8 free spins plus extra free spins are on offer for every scatter. You must spin the Bonus Wheel before the free spins feature commences.

On top of that you can gain up to 4 more free spins with multiplier wins of up to 3x. Moreover, the wilds only pitch on Echo Rolls.

Upsizer Feature

The Upsizer gives you the opportunity to purchase Modifiers. In other words, if the Bonus Wheel did not offer you any.

Suppose the game factors in the cost based on your average bet per spin. You also gain an extra free spin for every scatter that appears on the reels.

Verdict: Aquanauts Slot

Had it not been for the massive jackpot of 50,000x and its features, Aquanauts would have been a slog. As a rule of thumb, Alchemy Gaming seldom ventures beyond its comfort zone.

Apart from the Rolling Reels or Tumble feature, there’s nothing out of the ordinary. Aside from the fact of course that the multipliers grow by 1x with each Cascade.

On a personal note, the slot clammed up for the most part. The Rolling Reels and Echo Rolls features were disappointing at best not to mention the free spins feature.

It doesn’t mean that the slot can’t explode. However, it would have been nice if Alchemy Gaming included the average jackpot hit rate. It’s pointless offering a jackpot of 50,000x, yet it takes billions of spins before one lucky player hits it.

The Upsizer feature allows you to snatch those Modifiers the Bonus Wheel didn’t offer you. In theory, Aquanauts looks like a promising slot and we can see that Alchemy Gaming really tried.

Fortune most certainly favors the brave with Aquanauts slot. The volatility stings like a jellyfish and it’s difficult to trigger the free spins feature.

If you can muster the courage and you have the bankroll to carry you to depths yet unexplored to man. Who knows, this slot might just hold riches beyond your wildest imagination.

Yggdrasil Gaming delivers a gem with the Calavera Rush slot. This Mexican-themed slot celebrates the Day of the Dead in style.

Once you start spinning, it showers you with free spins and multiplier wins of up to 10x. The jackpot is $500,000 and it runs on an Avalanche mechanic for repeat wins.
