- Reactoonz is a 3D slot from Play’n Go which lets players defend the earth from invaders and win real money along the way. We’ll be putting this video slot to the test and assessing everything.
Reactoonz is a slot game set in a parallel universe filled with aliens, strange powers, and exquisite prizes for players. It’s a sequel to Energoonz, so it’s not surprising that the game follows the same story and same format.
The goal of the game is to connect the same aliens with every spin and please the evil Gargantoon alien sitting on the right. The more aliens you manage to connect, the more his energy level rises. When it reaches a critical level, he’ll leap into the game and start a chain reaction that will benefit you greatly, as this is the main feature of the game.
Visuals and Sound Effects in Reactoonz
The game is superbly animated, with gorgeous and colourful graphics. The entire main screen is neatly organized and made to bring you further into this strange universe with aliens and quantum powers.
All symbols come in the shape of small aliens who keep moving and making noises, while peculiar yet exciting background music is heard. There’s also the massive Gargantoon alien, following the show attentively, as long as you keep playing. But as soon as you stop spinning the reels, he’ll quickly fall asleep and grace you with constant snoring. The entire setting is entertaining and quirky, so everyone who loves such joyful slot games is bound to adore Reactoonz.
Reactoonz Slot Gameplay
The gameplay of Reactoonz is straightforward. You only need to choose the bet amount and start spinning. There are buttons to help you pick the exact bet amount, and it can be anywhere between 0.2 and 100 coins.
Playing the game is incredibly exciting, though. The 7×7 grid with no paylines resembles games like Candy Crush, and the main objective is the same as it is in those games. You spin the reels as you would in any slot, but to win, four or more of the same aliens need to connect. Each alien pays differently, so in that respect, the game is similar to regular slots.
Also, there are smaller, one-eyed aliens, and with every spin, one is marked as the fluctuating symbol. This means that if two of these become part of a winning combination, they’ll turn into Wilds and stay on the grid to substitute for any other symbols.
As for other gaming options, there is a detailed Autoplay feature you can use at any time. It is activated by pressing the button right next to the Spin button. Outside of that, the game also allows you to turn the Fast Play option for faster gameplay.
Wilds and Bonuses in Reactoonz
The main feature of the game is the Gargantoon feature that works in the background with every spin. In essence, the more connections you make within a single spin, the more the power bar of the Gargantoon alien fills up. If it reaches critical mass, the massive alien will appear on the 7×7 grid.
If you win on 25 symbols, a random Quantum feature will be added to the power bar. Once four of these are added, the fifth one you get will turn into the Gargantoon, i.e. the massive alien who appears on the grid.

The alien starts as a 3×3 massive monster, then divides into 2×2 Wild symbols, and then they turn into nine smaller Wild symbols. All of these symbols cascade from top to bottom, bringing you massive prizes in the process.
Even though this is the main feature, the four Quantum features you get before Gargantoon are also rewarding. Each does something unique:
- The yellow, Implosion quantum feature transforms a couple of symbols into Wilds and destroys adjacent symbols, bringing you more rewards in the process.
- The red, Demolition quantum feature destroys every one-eyed alien on the screen and all matching symbols.
- The blue, Incision quantum feature cuts two diagonal lines on the grid and allows the same symbols to appear on both, giving you higher winnings.
- The green, Alteration quantum feature picks out the one-eyed aliens and turns all of them into other symbols.

In the end, there is also the random Instability feature. In every non-winning spin, you have the chance of getting four to eight Wilds anywhere on the grid. This can significantly increase your winnings, depending on where and how many Wilds land.
Reactoonz RTP %
Reactoonz has an above-average RTP of 96% and high volatility. This means that the game tends to reward you more than enough, but it’s also very unstable. You’ll get sporadic wins, but they’ll be quite large.
The RTP is what matters here, as it clearly shows that the game will give you a lot of your money back, while the volatility indicates that you’ll also have a good chance of receiving some incredibly high wins if you play long enough.
Final Thoughts
In summation, Reactoonz is a great slot game, one of the best and most popular Play’n GO has to offer. It’s different from most video slots with its 7×7 grid and no paylines, but that’s precisely what makes it so appealing.
It has stunning graphics and lovely sound effects and melodies, but it’s also abundant in the special features area, especially with the highly rewarding Gargantoon feature. Couple that with the great RTP percentage, and you have yourself an enjoyable slot game worth playing.

Welcome an extra-terrestrial invasion from the Reactoonz slot!
Reactoonz Slot is a highly energetic and playful slot from Play’n GO with a lot of charm. We don’t quite know why these curious aliens have arrived, or what they want, but we’re glad they’re here.
Reactoonz söpt is the sequel to Energoonz, another game made by Play’n GO that couldn’t be more different.
Play’nGO is one of the leading suppliers in the industry, who boast more releases than anyone else, more tools to support ambitions and consistently high quality in everything that bears their name.
Reactoonz was the start of something special from the Casino Software Provider, and really set the standard for Cluster Pays games going forward.
To this day Reactoonz slot is still highly coveted and widely played everywhere, and for good reason.
This game may seem a little confusing at first, especially to those not too familiar with the format, so allow us to explain…because you’re not going to want to miss out on this one.
Extra-terrestrial Action in the Reactoonz Slot
When you load up Reactoonz you’ll be greeted by a colourful assortment of different characters all sat comfortably occupying a space upon a 7×7 grid.
The theme, of course, is a celestial space theme and is simplistic in the way that the background is simply the void of space. The various aliens are animated and emit the odd blink, or movement or sound, bringing a little life into the game.
The sounds and music are quite cheerful and fun, and it really puts you in the mood for a good time with these friendly little aliens.
Reactoonz Slot Symbols and Betting Options
Reactoonz is a cluster pays slot, which is one of the more fun mechanics out there at the moment. You’ll need 5 or more aliens of the same race joined horizontally or vertically to form a win.
The top symbol is the Pink Alien, then the Green, Orange and Blue. The easiest way to differentiate between higher and lower-paying symbols is that the higher paying ones have two eyes.
Lower paying symbols are represented by all the aliens with only one eye, represented from highest to lowest paying, these are purple, red, green and yellow. Wilds are also present in the game and substitute for all symbols.

Betting options are quite extensive for this one, meaning there’s plenty enough option for every type of player to either take it a little bit easy or go all-in for them bigger hits. Lowest Bet is 0.20, and the highest bet is a huge 100.
Base Game and Features
As previously mentioned, 5 or more of the same symbols need to connect either horizontally or vertically to form a win. Winning symbols will ‘teleport’ or disappear out of view, and a cascade will occur.
The cascade will cause symbols in the position above the winning ones to fall down to fill their space, and new symbols will appear from the top of the grid to fill their spaces until all positions are filled.
There’s a lot of unique features at play that makes the game more interesting while also giving it more potential.

Gigantoonz
4 matching symbols adjacent to each other in square shape will automatically form a Gigantoon. These 4 matching symbols will merge into a giant version of their former selves and fill up 4 spaces on the grid.
Wins are then doubled in any winning combination that the Gigantoon is a part of.
Fluctuation
One random one-eyed (low paying) symbol will glow, if any of the glowing symbols are part of a winning combination, they will leave 2 Wild symbols behind. Wilds substitute for all symbols.
Quantum Leap and Quantum Features
In the top right of the screen, you’ll see an empty meter. This meter will charge up when winning, and when one bar is full, a random Quantum feature will be added to the queue.

A win on 25 symbols is required in order to charge one Quantum feature. Up to 4 Quantum features can be queued. When the bar is charged for the fifth time, the Gargantoon feature will activate instead.
If no more wins are present, the queued-up Quantum Feature will be used, and wins that result from these will contribute towards the next Quantum Feature or the Gargantoon Feature.
The round ends when all queued Quantum features have been triggered and there are no more winning combinations.
The following Quantum Features can be obtained.
Reactoonz Slot Demo
- Implosion – Transforms 3 to 6 symbols into wilds, and destroys adjacent symbols.
- Incision – A Wild symbol will spawn into the centre, which will then create two intersecting diagonal lines through the grid. Both lines will show the same symbol, and can even turn into Wild Symbols.
- Demolition – Destroys all one-eyed (low paying) symbols
- Alteration – Chooses 1 random one-eyed symbol, all symbols of this type will be transformed into another symbol.
The Quantum features are where Reactoonz really shines. Queueing up multiple features at once can make for some of the most exciting gameplay you’ve ever seen.
Early game, and overall, Implosion and Incision are the best ones, as they’re more likely to help you further your progress on the Quantum leap.
As a general rule of thumb, you’ll want as many Implosions and Wild Incisions as you can until you get to Gargantoon, Demolition and Alteration can help too.
But less so, and shine better when they’re clearing the board of low paying symbols, or turning them into higher paying ones in anticipation for Gargas arrival.

Gargantoon
Here comes the big guy! Gargantoon is achieved by filling the fifth bar of the Quantum leap meter. When this happens, Garga will teleport from the right side of the screen where he was waiting onto the grid covering a 33×3 space.
Garga acts as a wild and substitutes for all symbols. After appearing as a 3×3, he will divide and move with each cascade. First of all, he’ll become two 2×2 Wilds symbols before finally dividing into 9 individual Wild symbols.
Reactoonz Slot
New symbols will cascade from above between each Gargantoon move, which allows for more and diverse wins.
Obviously, you’re going to want Garga to connect as many high paying symbols as possible, as this is where you’ll see the best return.
Our Verdict
Even though Reactoonz is highly loveable, fun and interesting…It is also a next level tilt game like no other. As you can imagine, these Quantum features don’t always come easy, as you’ll need 25 wins to trigger each one.
Seeing that bar a slither away from a Quantum feature, or even Gargantoon is enough to make you want to drop kick your laptop, computer, mobile casino or tablet.
Getting Alterations and Demolitions early on can also have this effect, as it’s pretty unlikely that subsequent Quantum features will happen unless you’re lucky, as these serve as more of a set up for Garga’s arrival.
These same features that ‘set up’ for his arrival, can also do the opposite. Quite often any of these features can trigger wins that quite suspiciously seem to cause high paying symbols to disappear, leaving the little potential for Garga.
Still, I suppose it’s to be expected, Reactoonz is a high volatility game after all. It has a High RTP of 96.51%, so it at least means that a decent proportion of your bets should, in theory, be returned as winnings.
Tilt aside, Reactoonz is an absolute banger of a game. It may leave you disappointed sometimes with some woeful Quantum features. If you enjoy it, you might want to check out the second part of the game: Reactoonz 2!
