Reactoonz 2 Features

Buckle yourselves in, because there’s a lot to learn about all the fantastic features you’ll find here in Reactoonz 2. You have to trust us when we tell you, despite how scary they might seem, they’re great fun once you understand what’s actually going on.

First and foremost, there are two different types of symbols in this game… Low paying symbols that are displayed as one eye and high paying symbols that are displayed as aliens with two eyes. 

Fluctuating symbols and the Fluctometer

Each and every time you click the play button one of the low paying symbols is chosen to fluctuate, if that chosen symbol is part of a win then an electric wild will fall into place and replace one of the removed symbols. 

The Fluctometer (which is on the right-hand side of the game grid) can hold up to 11 charges in total and will randomly add up to 3 electric wilds at a time when it’s completely full. The Fluctometer is active throughout the entirety of gameplay until a Gargantoon disables it.


Whenever non-wild symbols are removed from the game by way of an electric wild another meter, known as the Quantumeter will begin to fill up. This meter resets after every round.

The Quantumeter has a total of 4 charge levels and can hold up to a maximum of 135 charges (removed symbols). The first level will require 55 charges, the second level will require 85 charges, the third level will require 110 charges and the fourth (overcharged state) will require 135 charges.

Wild Pair Explosion

If there are still more than two Electric wilds remaining on the grid after all of the bonus features have culminated then the Wild Pair Explosion feature will trigger. If 2 Electric wilds are sat adjacent to each other in any direction then all of the symbols are removed from the grid. If they’re not adjacent then all of the symbols that sit between them are destroyed. The Wild Pair Explosion feature does not award players with a payout, but instead the Quantumeter is charged.

Reactoonz 2 - Energoon Wilds

Energoon Wilds

Energoon wilds are wilds that remove a certain number of symbols around them. They vary in size depending on what level of the Quantumeter they’re unleashed on.

Reactoonz 2 - Gargantoon Wilds

Gargantoon Wilds

When a 3x3 Gargantoon wild is activated it will cause a cascade, after this it will break down into two 2x2 Gargantoon wilds. After triggering another cascade, it is then replaced by nine standard Gargantoon wilds

Reactoonz 2 Review

Developed by Play’n GO Reactoonz 2 is the much-anticipated sequel to one of the most popular space themed online slots of all time, Reactoonz.  

We’ve made no secret of our love for grid-based cluster pays slots, they’re a LOT of fun, and considering the original Reactoonz slot was one of the best, this title had big boots to fill. 

Speaking frankly, this slot is intense, especially when you start playing for the very first time. There’s a lot going on and all of the features and mechanics that have been squeezed into this slot take a bit of getting used to. 

We’d highly recommend giving this game a fair few spins on demo mode before you actually start playing with your own money, so by the time you’re ready to play properly you fully understand what’s going on around you (because there will be a lot going on around you!). 

Reactoonz 2 is a LOT of fun, this game is a favourite with online slots streamers and YouTubers because it’s exciting and often lucrative, so if you want to see what all the hype is about we’d highly recommend giving this slot a spin.


Reactoonz 2 isn’t at all dissimilar to the original Reactoonz game, in fact it’s almost identical. 49 aliens of differing colours (red, blue, green, yellow, purple and orange) all sit in the grid, some smiling, some looking glum! Behind the reels is a mesmerizing swirling purple vortex.

There are a few strange looking high-tech machines to the right-hand side of the reels that are related to the game’s bonus features, whilst on the left the winning clyster of symbols are displayed in what looks like a sciencey glass tube. 

A space-age techno beat plays in the background during the entirety of gameplay which picks up and becomes more cheerful and exciting when the bonus features are triggered.


Those of you have played the original Reactoonz online slot will know exactly what to expect from this slot. The game is played on a 7 x 7 grid with all wins registered when a cluster of five or more symbols and banded together. These winning symbols are removed from the grid following the win and new symbols will fall into the vacant spaces left behind.

The game itself is incredibly easy to navigate, players can change their stake by clicking one of the options displayed along the bottom of the screen. The play button and autospin button sit next to each other on the far right-hand side of the screen. 

If players wish to automate their gameplay then they can set a maximum of 100 autoplay spins as long as loss (and win) limits are set beforehand.

Win Potential

One thing we love about Reactoonz 2 is the win potential this slot has. This high volatility cluster pays slot has a bog-standard RTP of 96.02% and a healthy maximum win of 5,083x your initial stake. If you have the bankroll to sustain your gameplay and aren’t afraid of waiting a little bit longer to pick up wins then you should find Reactoonz 2 pretty lucrative over time.

Our Verdict

Reactoonz 2 is chaotic, but a LOT of fun. There aren’t many online slots quite as thrilling as this one when a chain reaction of wins eventually kicks in. If you’ve got the patience and bankroll to get stuck into this space themed high volatility title then we urge you to give this slot a shot! It’s absolutely perfect for you hardcore slot enthusiasts.
