How to play Energoonz mobile slot

Is the Energoonz slot a machine or video game? Honestly, we still haven’t decided, but you can gamble on it, and it’s cute. So close enough?

Play’n GO have really surprised us with this Energoonz mobile slot release. We were not sure what we were expecting when we opened up Energoonz slot, but certainly not the 5×5 grid of tiny little alien heads blinking at us and bursting into a blaze of energy upon any vertical or horizontal win of 3 touching symbols or more.

The sounds may not be anything to shout about, but you’ll be pretty cold-hearted not to at least smile at the cute little symbols on your screen.

Especially when, on every win, the aliens disappear, and you get a wild symbol in its place, allowing you to create more wins. Plus, you get an increasing multiplier on every win, meaning that the wins get progressively bigger on each concurring win.

Is it as exciting as it sounds? Well, yes… and no… winning big on Energoonz mobile slot is going to take a while or a very lucky free spin. The return to player rate is a decent 96.73%, yet this mobile slot pays out small.

This is because those multipliers on every win increase with each win, which means the symbols are generally of quite low value, expecting you to hit those multipliers for the bigger wins.

We got to 8x at one point, but mostly you get to about 2x to 4x multipliers. This is certainly on the lower-risk end of the mobile slot scale, paying you little but often.

That said, we’ve had a few wins of 40x to 60x our bet that made this little mobile slot interesting. Usually combined by clearing most of the board and hitting the strange, but richer in value and reels, free spins rounds.

We say ‘strange’ because you go from happy, lively aliens to what appears like dead grey aliens that you have to get back to life with a jolt of electricity. Morbid? Or just us?

Could we make up our minds about this mobile slot? No, it still sits a little too oddly in that in-between space of ‘social games’ and ‘slot machines’. But if you like low-risk slots with the odd chance of coming out on top, this is certainly one of the more unique choices.

And if you like it, you should check out some other grid slots to play online.

In-game bonus features

Semi-Cascading Reels: Unlike Gonzo's quest or Pixies of the Forest mobile slot, these cascading reels do not get replenished from above. But they do drop down to create more wins, and a multiplier of +1 appears with each win. We've received up to 8x on the board, but we suspect  this could go as high as 10 or maybe even 12 times.

Wild Symbol: This symbol only shows up once you've created a successful winning combination. When the aliens disappear, they leave behind a wild energy ball that can replace all the symbols. You may think it odd that the wild symbol doesn't show up on its own, but the wins are frequent enough that you'll be glad for this symbol to help increase that all-important multiplier on each win.

Free Spin Bonus Rounds: When the aliens 'land' on the reels, you'll see the word 'bonus' etched on the background of this mobile slot. If you manage to clear all the aliens covering these letters (not as hard as you might think, although sometimes feels impossible), you'll get 10 free spins.

On these free spins, you'll be taken to a secondary reel with little grey sleeping (dead?) aliens that are richer in value than their base game counterparts. In combination with a good streak in the base game, the free spins round can bring about a tidy sum - even if, on their own, they don't hit as big as we would have liked.


  • Free spins with up to 5x multipliers
  • High 96.73% RTP
  • Low 0.20 minimum bet


  • Small base game wins

Energoonz Review Conclusion

What a strange little mobile slot. Energoonz is stuck somewhere in the middle with a new generation of slot trying to compete with all the other social games that are calmly sitting on your mobile phone.

Thing is, this video slot doesn't feel like it belongs to an Android Casino or a iPhone Casino. It feels like it should belong in the Play store or App store. It will turn many purist slot players away, we suspect.

But if you are after something a little different, low risk and with some fun graphics, then we think you should give Energoonz slot on mobile a chance. After all, NetEnt have made a reputation for themselves by bringing new and exciting features to online and mobile slots. So why not reward Play'n GO for doing exactly the same?

You can also play the follow up slots to this game with the Reactoonz and Reactoonz 2 slots.
