Energoonz slot lets you explore the life of cute alien creatures. They don’t do much unless you land a win. That’s when things come alive, creating more winning opportunities. Cascades, Wilds, multiplier upgrades… there is plenty of stuff that happens, and sometimes these sequences can even trigger a bonus.

Energoonz slot review

Overview of Energoonz Slot by Play’n GO

This is a fun slot that started the famous Reactoonz series from Play’n GO. Released in 2013, it still feels fresh and relevant over a decade later. The developer calls the alien creatures “little bundles of energy”, hence the title Energoonz. And when they are active, the show they can put on is electrifying.

Bonus and base modes are quite different. Lines that are used in the base game are switched for scatter pays in free spins. But you can’t just buy the bonus to quickly explore it. Because back in 2013, feature buy wasn’t a thing. So, your free Energoonz slot play experience will last for a while.

The slot offers a low volatility gambling experience, which is great if you enjoy payouts that are spread rather evenly and there are no crazy winning or losing streaks. But typical to Play’n GO, the slot has multiple RTP settings, and the RTP figure isn’t specified in any of the game documents when you load the slot.

How to Play Energoonz Slot Game

Energoonz free slot

When you open the game Paytable, there isn’t much explained. But that isn’t a problem. Once in demo mode, you can just play the game for a while to figure almost everything out. There’s a 5×5 grid that pays winnings when matching aliens or other icons land horizontally or vertically three or more in a row.

Energoonz demo will show you that it’s not a cluster mechanic, because only straight lines are awarded. But the same symbol can be part of multiple lines, which gives the impression of the cluster mechanic. And it’s not a classic payline engine either, because winning combos can form anywhere on the grid.

Energoonz Slot Features: Wilds After Wins

This is probably the most exciting thing in this game. Whenever there’s a 3 of-a-kind winning combo, it disappears but leaves a Wild symbol right in the middle. This helps get more payouts, and when there are multiple winnings not far from each other, it can be a lot of help.

When you test Energoonz free slot, look for plasma balls. These are Wilds. They often come in handy. You can keep track of your winning combos in a special window on the left side of the screen. If there are multiple win records, you’ll often see plasma balls as part of the combos.

Energoonz Slot Cascades

The slot does feature a cascading mechanic, but it’s different from what you typically expect. The thing is that new symbols don’t drop in to fill the gaps. But this modification has a purpose. As you’ll learn later in this Energoonz slot review, clearing space creates an opportunity to trigger a bonus round.

Progressive Multiplier

Above the window where you keep track of your round wins, there’s the multiplier figure. It increases with every cascade. The game rules don’t specify the maximum multiplier value. But it won’t grow very high. New symbols aren’t introduced to fill in empty spaces after the cascading effect settles, and a round ends after a few cascades.

Energoonz slot features

x2 can be seen regularly. x3 is less frequent, but you don’t need to have a long Energoonz slot free play to see it. During my experience, the maximum multiplier I received was x7. That’s a solid figure, and it will probably land every now and then. Usually, there will often be bonus triggers following such multipliers, because it happens when more than half of the symbols are cleared, which often exposes BONUS symbols.

Energoonz Slot Bonus Game

Every round there will be at least one column that has BONUS written on it. When at least one such column is cleared revealing the word, players unlock a bonus game. The more of these columns are cleared, the better the bonus because the multiplier for the feature increases.

When I played free Energoonz slot, it felt like bonuses were rather frequent. My first two free spins were activated within around 150 rounds. So, you definitely aren’t waiting for several hundred rounds to get a bonus game.

The way this bonus is played is very simple. 5+ matching symbols anywhere on the grid get you a payout. This mechanic is called Scatter Pays, and it’s extremely popular today.

Energoonz Slot RTP, Volatility and Max Win

The volatility of this game is between low and medium, which means winnings should be spread rather evenly. Of course, the outcomes are still very much unpredictable, but there shouldn’t be crazy ups or downs in terms of payouts.

RTP in Play’n GO slots is the issue. Not so much because the range is quite wide. But because game rules don’t tell which RTP model is used. So, you don’t know if it’s the lowest figure, the highest or anything in between. For this release, there are five payback settings: 96.69%, 94.74%, 91.75%, 87.69% and 84.69%.

Top Prize

The max win is x1,000. And how to get it is something we haven’t mentioned earlier in this review. This special prize is awarded for clearing an entire grid. During my Energoonz slot demo experience, I had multiple times when there were only a few symbols left. But don’t be too excited as these last few icons are hard to get rid of.

Slots Similar to Energoonz

As mentioned earlier, this release was the first in the popular slot series. Reactoonz that came next is by far the most recognized game. It took gameplay to a whole new level with a bigger grid and a bunch of boosters ready to unleash their powers when the Quantum meter is filled.

There are massive symbols with multipliers. This time, when winning combos disappear, the gaps are filled with new icons, allowing a cascading sequence to theoretically continue without limits. The highlight is the deployment of Wild Gargantoon. It’s a 3×3 symbol that splits into smaller symbols with every cascade.

The series then continued as the studio started to add more features, more characters. But none of the releases that followed were able to reach the level of popularity Reactoonz had.

Pros & Cons
  • Energoonz is an interesting game that shows early variations of different mechanics.
  • It’s fun and can keep players entertained by using a combination of cascades, Wilds and multiplier upgrades.
  • The base game is exciting and will often be even more thrilling than free spins.
  • No feature buy option.

Final Thoughts on Energoonz Slot

There aren’t many slots that age so amazingly well. Players will enjoy the set of features it offers as it provides lots of thrilling moments. Energoonz slot machine comes with different variations of very popular mechanics. Clusters aren’t exactly the clusters we know, and modern cascades are different. But these little things just make the slot more appealing for some players.
