Aeterna Slot Review

Blast off into space in the Aeterna slot, an unusual game from 1x2 Gaming and Black Pudding Games that is the first to use the Orbital Reactor game mechanic. The game features 7 symbols that appear in a series of Orbital Paypaths. To create a winner, land 3 symbols on a paypath. This also causes a cascade that also brings an expanding win multiplier into play. Land 2 winning combinations on the same spin for the Twin Win Booster which clones symbols to create a 6-of-a-kind winner. There’s also a Free Spins Bonus feature that can award unlimited free spins with all the standard multiplier values double. Find out more about this innovative slot in our detailed Aeterna review.

Aeterna Slot RTP, Details & Wager Limits

The game mechanic in the Aeterna slot is a novel one. There are 3 lines of 3 symbols that create 7 symbols in total. To create a winner, land 3 or more matching adjacent symbols.

Developed in partnership with Black Pudding Games, Aeterna is the first slot release to be played using the Orbital Reactor game engine. On each spin, you’ll see 7 symbols appear on 3 concentric paypaths. To create a winning combination, land 3 or more matching symbols in adjacent positions on the paypaths.

Stakes here start at 10p per spin, rising to a maximum of £50 per spin. To adjust, click on the setting tab then click on the + – button and adjust to suit. It’s here that you can set autoplay too. You can run up to 100 autospins with win and loss stop limits available.

The Aeterna RTP is 96.19% which is solid enough. Theoretically, there’s no limit to the potential wins available given the chain reactions and cascades.

Theme – Audio & Design Features – blast off into outer space

Aeterna slot base game

The design in the Aeterna slot is simple but nicely done. Set against a space backdrop featuring Saturn, stars and assorted floating asteroids, there’s a futuristic, Kraftwerk-style soundtrack playing while you spin which is a good fit for the space theme. The game engine is certainly unusual but the sound and visuals impress.

The reels are made up of 6 brightly coloured symbols. They’re shapes rather than specific objects but serve their purpose nicely against the black expanse of space in the background. The most rewarding symbol is the radioactive looking green cube. Land 3, 4, 5 or 6 of these in combination and you’ll receive an award equal to 12, 500, 100 or 1,000 x your total stake.

There aren’t any wilds here but there is a bonus, the A symbol, which triggers the feature. We’ll look at these free spins shortly.

You can blast off to Aeterna on all devices including desktop, tablet and mobile. If using a smartphone, portrait mode is the best option. The sharp visuals stan out nicely, even on the smaller screen and the visuals are neat and crisp. The Aeterna mobile slot is nicely crafted.

Bonus Features in Aeterna

This sci-fi-themed slot is unusual in a number of ways, starting with the game engine. Other extras include Twin Boosters where 3 of a kind wins can morph into a 6 of a kind winner complete with multipliers. More traditionally, there’s a free spins round complete with enhanced multipliers.

Cascade Reaction feature

If you create a winning combination made up of anything apart from a bonus symbol, the Cascade Reaction feature follows. All the original winning symbols are removed and new ones drop in and replace them. These continue as long as a new winning combination hits the paypaths.

Each successive cascade win also increases a multiplier. These values are shown in the ring that edges the reels. The multipliers resets to 1x following a winless cascade.

Twin Win Booster Bonus feature

The Twin Win Booster Bonus feature is triggered if you land 2 separate 3-of-a-kind combinations on the same spin. One symbol is picked on this special spin, filling all the outer positions on the Paypath and in the processing creating a 6-of-a-kind winner.

Free Spins Bonus feature

Aeterna slot Free Spins Bonus feature

Land 4 or more of the A bonus symbol on the same spin and you’ll receive an award of 6, 12 or 60 x your total stake. You will also trigger the Free Spins Bonus feature. You’ll then get to spin a bonus wheel which determines how many free spins you’ll play. Depending on where the virtual pointer lands, you’ll get 5, 10, 15 or 30 free spins.

Boosting your winning chances here are enhanced multipliers which are double the value of what’s on offer in the base game. These increase with successive cascade wins.

Retriggers are possible too. Landing 4 or more A bonus symbols adds the same number of free spins as the original trigger. For example, if you originally received 15 free spins, a retrigger adds another 15 free spins to your tally. There’s no limit to the number of potential retriggers available.

Aeterna Review Summary – unusual but innovative

If you’re looking for a slot that offers something a little different then you’ve come to right place. The game mechanic takes a little getting used to in the Aeterna slot game.

There’s plenty to like when you’ve got your eye in though. The gameplay is relatively simple but the cascades with expanding multipliers will deliver the best action. That’s definitely the case in the retriggerable Free Spins Bonus feature where the value of the multipliers from each cascade are doubled.

If you like slots with a sci-fi theme or you just fancy trying something unusual, Aeterna is a game to consider. Alternatively, you have the Milky Ways slot from Nolimit City which is very good.
