Reactoonz Slot Review – Mischievous Alien Monsters

Reactoonz is a sequel to Play’n GO’s Energoonz, but this time the cheeky creatures come loaded with Quantum energy and five unusual base game features! 

Reactoonz comes with a cluster pays mechanic, which means you can get payouts for more than five or six symbols, which is a little different from most slots. I’ll go into more detail about this, as well as how I checked this slot, including its overall design and what you need to do to trigger the bonuses, throughout this Reactoonz review.


What I Checked in Reactoonz

Reactoonz may play a little differently from most slots, but it still needs to be examined using the same factors. These are the things I checked:

  • Slot overview
  • Bonus rounds
  • Any unique features
  • The story behind the slot
  • The game’s developer

What Is In This Reactoonz Review?

Here’s a brief overview of what to expect from Reactoonz.

Slot typeCluster paysNumber of rows7
ProviderPlay’n GOReels7

Reactoonz is a 7×7 slot provided by Play’n GO filled with eight kinds of cute, colorful aliens. Its cluster pays mechanic means you can get high payouts from 15 or more matches, which is undoubtedly its main selling point. However, I also really like the choice of bonus features, as I’ll highlight below. 

What Game And Bonus Features Does Reactoonz Have?

Most of these are fueled by Quantum energy, Reactoonz’ unique bonus mechanic. There’s a ton to unpack, so I’ll go through everything below:

BASE GAME FEATURES4Instability, Gargantoon, Giantooz, Fluctuation
BONUS GAMES FEATURES4Implosion, Demolition, Incision, Alteration

Fun and Explosive Base Game Features

You don’t even need to land a winning combination to trigger some of these base game features, which is a refreshing thing to see in a slot. First, though, I’ll start with the basic symbols.

The Symbols

Reactoonz includes four two-eyed aliens with maximum payouts between 75x and 750x the stake, for 15 or more matches. The four lower-value one-eyed aliens come with maximum payouts between 3x and 10x for 15 or more.


Instability is the one base game feature that can appear after an initial non-winning spin. The Gargatoon drops between four and eight wild symbols to give us more winning combinations.


This happens when you match four aliens in a square. When you do, the square turns into a giant alien head and doubles your winnings.


Each spin decides on any one-eyed alien to be a fluctuating symbol. If the fluctuation forms a winning combination, it leaves two wilds.


Winning combinations fill up both the Quantum Leap meter (to trigger bonus) and a smaller Quantum queue. If the latter gets filled up, it wakes up the Gargantoon. This appears on the reels as a wild, then after new symbols cascade down, Gargantoon splits and moves positions. First, into two 2×2 wilds and then into nine on the following cascade.

No Bonus Buy Feature Here

Unfortunately, Reactoonz doesn’t feature a Bonus Buy option.

Can You Hold and Win?

Unfortunately, there also isn’t a Hold and Win mechanic in Reactoonz.

The Gigantic Bonus Game Feature

After filling up the Quantum Leap’s machine energy with winning combinations, you’re left with five possible bonus game features.


When three to six symbols become wild, they create an implosion. During implosion, the aliens nearest the wild symbols get destroyed.


In incision, the grid gets divided by two diagonal lines running from a central wild. Each symbol along a diagonal also becomes a wild.


The low-value aliens and any matching symbols are destroyed. This makes way for larger potential wins.


All instances of a random low-value alien transform into another alien. That alien can either be of higher or lower value.

Special Features You’ll Find in Reactoonz

Reactoonz also comes with a host of features to customize your gameplay.

Autoplay option👍
Change the speed👍
Mute the sound👍
Adjustable bet size👍

As you might expect, you can tweak a bunch of options. I was especially pleased to see Reactoonz lets you speed up gameplay with a ‘turbo’ (lightning bolt) icon, as well as set win/loss limits in the autoplay section.

Is There a Story Behind Reactoonz’s Theme?

Yes, in that Reactoonz follows on from Play’n GO’s own Energoonz slot, although it boasts plenty of unique features. The graphics and sound have also received an upgrade, as I’ll note below. 

Cute Graphics

These aliens are adorable with their own little animations that will play every so often;  yawning, blinking, looking around– you name it! In fact, everything is animated in a colorful 2D style, including the sleepy Gargantoon on the right of the reels. 

Winning combinations and bonus features also trigger with vibrant particle effects, like explosions and lightning. Meanwhile, the space background subtly shifts in color as dust motes drift past.

Alien Sounds

The background music starts as minimal ambient sounds before dramatically building into an upbeat electronic score the longer you play/the more wins you land. Otherwise, the aliens make little yelps and burps every so often. All of this adds up to a delightfully immersive experience.

Who Made Reactoonz?

The company behind this game is Play’n GO, a reputable developer well-known for its high-quality games and interesting mechanics. Reactoonz is one of its most popular titles, but I’ve highlighted a few more below.

A Few of My Favorite Slots by Play’n GO I Highly Recommend!

  • Reactoonz 2
  • Book of Dead
  • Rise of Olympus

Is Reactoonz Worth Playing?

Absolutely. There are plenty of reasons to give Reactoonz a spin, least of all its cluster pays mechanic and adorable, immersive game design. 

It vastly improves upon the original Energoonz slot with its multiple explosive bonus features and raises the bar for other cluster pays slots to follow, like Sugar Rush by Pragmatic Play.
