How to Play

Reactoonz should not present a hurdle for season slots players. It is a pretty standard, 7-reel, 7-line slot, that even newbies can master in a short while. Like most online slots, it has a set minimum and maximum. The set minimum is €0.20, whereas the set maximum is €100. The way to win a prize is to cluster 5 or more aliens of the same race. The more you cluster, the higher the prize is.

If you are new to the world of online slots, in this section we will provide you with a step-by-step tutorial on how to play Reactoonz.

  1. Register an account with one of our scanned casinos
  2. Go through the Play’n GO slots library and find Reactoonz
  3. Select the Reactoonz slots and make a bet - from €0.20 to €100
  4. Start spinning

Now that you know the rules, we are going to talk about the thing that interests most bettors. The RTP and volatility of the game.

RTP and Volatility


An RTP of 96% is paired with high volatility.

Reactoonz’s RTP is 96%, which is the industry average. The problem comes when that RTP is paired with the high variance rate of the slot - so players will certainly get a number of dry spins, that may even exceed the number of winning spins. Sure, a high volatility rate means that a win might yield a greater prize.




The theme is the one place where Reactoonz shines above the competition. While “alien invasion” may not be super original, Reactoonz does it really well. Much better than most other slots handle their theme.

The gameplay is set in space, on the alien spaceship, where 8 little aliens, led by Gargantoon are on their way to invade the planet Earth, and it is up to you to help them do so. The game takes heavy inspiration from the “cute little monsters” genre of slots, as well as, from the classic alien invasion genre of science fiction films.

True to that, the music is atmospheric, spooky, and peppered with the alien’s language, laser-beam sounds and the clanking of levers that might be found on a spaceship. It is by far, one of the best-handled slots themes that we have come across.

And that is true for the design of the game symbols as well. Reactoonz features 8 unique alien symbols. Each of the symbols offer 8 different payouts, depending on how many you cluster together.

Mobile Compatibility

Reactoonz uses the HTML5 platform, which means it is compatible with mobile phones and tablets. Tablet users can access the game directly from the website, whereas smartphone users can even use older models of both iOS and Android phones to access the game through apps.

About Play’n GO

Play’n GO is the developer behind Reactoonz, as well as dozens of other slots. Their different branches are all licensed, two of them by the Gambling Commission in Great Britain and one of them by the Malta Gaming Authority.

They have an online presence over several different social media platforms, including Twitter, Instagram and YouTube. You can find their accounts by going to the Play’n GO website. On the same website, you can also browse all of the slots that Play’n GO have developed.

Bonus Round & Free Spins


Reactoonz, like most online slots, has quite a few features that can’t be found on land-based slots. We are going to take a look at a few of them in this section.

The Quantum Leap Feature

As we said, Reactoonz takes heavy inspiration from classic science fiction. One of the staples of science fiction is “technobabble” and Reactoonz incorporates said “technobabble” into its features. Thence comes the Quantum Leap feature.

The Quantum Leap charges up the more you win, and one random quantum leap is added to a queue after you win on 25 symbols. The queue has a capacity of up to 4 quantum features. When you charge it up for the 5th time, this triggers the Gargantoon feature, which we will talk about a bit later. There are four different aspects of the quantum feature.


The Gargantoon feature is triggered when the quantum queue is filled up. Gargantoon is a 3x3-sized monster, and it replaces all of the symbols in its wake. Once a cascade is triggered, Gargantoon separates into two, 2x2 Wild symbols and further, it can separate into 9 individual Wilds.


Like a lot of online slots, Reactoonz has a Cascade feature. Once you remove a symbol from the screen, new symbols will replace it. If they also get removed in the same spin, this triggers a Cascade, multiplying your wins.

Reactoonz Demo Play

Reactoonz can be played for free in demo mode. The Play’n GO team realizes that there are many people out there who wish to play slot games without risking their cash. For them, the game features a demo play, where they can spin to their hearts content without betting a single penny. The demo play is also a great way to get a feel for the game, and find out whether it is for you or not.

Max Win


The top prize in Reactoonz is 4,570x.

The maximum win available in Reactoonz is 4,570x and can be won by betting the highest maximum wager. And then triggering as many cascades as possible while getting the maximum multipliers. The task is not easy, however, it is possible. Though, with the high volatility rate, it may be more difficult than in other slots.
