How to Play the Aquanauts Slot Machine

Delve into the deep blue, where detailed images of aquatic life mingle with 4 divers, their yellow mini-sub, and valuable bonus symbols. The graphics look good across the desktop, Android, iOS, and Windows versions, and there’s a eerie underwater soundtrack to bring the deep to your favourite device.

You can explore this environment for between 0.30 and 21.00, including at any of our recommended Betting Sites. A tap on the coins motif reveals all of the options, while the 3 little dots at the top of the game take you to a paytable, where you see how much you can actually win from the various symbols. The Aquanauts slot machine has 3,125 different ways to match symbols across connected reels from the left, with the highest value diver worth up to 6.67x the total bet.

In common with most online slots, the game has an automatic spins option, which you trigger with a click on the circular arrows, as well as a fast-play mode that starts when you tap the lightning bolt button. An Upsizer bonus buy option triggers the free games on the next spin.

Free Spins & Other Features of the Aquanauts Online Slot

A golden ‘W’ wild symbol pays 10x your bet when it crosses all 5 reels, and also does what wilds tend to do and acts as other symbols if it can then complete or improve a win.

A Rolling Reels mechanism removes winning symbols from the reels of the Aquanauts slot game, and those above then drop down to fill the gaps. New symbols appear from above the reels and if this creates a further win, you get another Roll. A win multiplier increases by 1x on every Roll in a sequence, with no upper limits and it only resets once a non-winning mix of symbols appears.

Randomly, the sonar to the side of the game lights up in an Echo Roll feature. It displays a random symbol that will drop onto the reels for a guaranteed win.

A red and white ‘S’ is the scatter symbol and any 3 will award 8 free spins, plus 2 more spins for each additional scatter on the triggering spin. Each scatter during the free spins adds 1 extra game to the total. You get to a spin a bonus wheel before the feature start, and this awards 2 or 4 extra spins, or Rolling Reel multipliers that increase by 2x or 3x. The wheel can also award only wild symbols, or only high value symbols on the Echo Roll feature.

Aquanauts Slot Maximum Wins, Average Returns, & Volatility

The 50,000x maximum win is only really possible over an exceptionally long string of Rolling Reels with a 3x multiplier increase in the free spins. Play the Aquanauts online slot at the maximum stake of 21.00 and it’s theoretically possible to claim a prize of 1,050,000.00.

This is a highly volatile game, so be prepared for comparatively few winning spins, but relatively high Jackpot Slots prizes can be won at any time. The return to players percentage is slightly higher than many other games, at 96.26%.

Our Thoughts on the Aquanauts Slot

Some animations from winning symbols would be welcome, but the Aquanauts slot machine has a pleasing design, and we like the underwater adventure theme. There are certainly no issues with the gameplay and features, with wild substitutions, Rolling Reels, Echo Rolls, and free games with potential multipliers all coming together in an exciting game.

Cracking the 50,000x maximum win won’t be easy, as you will need a very long run of Rolling Reels to reach this target. But anything is possible.
