Reactoonz Slot – Expert Review & Free Play Demo

Themed around space and aliens, the Reactoonz slot machine is a pretty interesting game.

Along with a quirky and creative theme, this slot machine also comes with a lot of action happening on the reels. There are as many as 8 features to expect in this slot machine and each is interesting and rewarding in itself.

There is no actual bonus round as Free Spins, for example, as everything happens in the base game. Reactoonz also features cascading reels just like in Gonzo’s Quest or Megaways slots, for example. The game is created by Play n’ Go and it is an antecedent of the Energoonz slot machine which comes with similar gameplay and is also themed around cartoon aliens.

Reactoonz Slot Machine – Theme and Design

Just like we’ve already mentioned, Reactoonz slot comes with an alien theme. But these are not the regular aliens we see in movies. No, these are, actually, cartoon one-eyed, two-eyed, or three-eyed smiley aliens. The whole design is quirky and fun. The graphics are sharp and of high-quality. And aesthetic pleasure is definitely not missing in this slot. Play n’ Go did a great job with this game. If we compare its predecessor Energoonz with Reactoonz, we can easily say that Play n’ Go did a much better job with smooth graphics and more detailed design.

The translucent reel board is set on the blue background what seems to be the space with waves of lights shimmering in the back. On the left side next to the reel board is a meter which is important for in-game features. On the right side, there is a sleeping three-eyed alien Gargantoon as well as another meter and both play a big role in activating in-game features. Also, while playing this slot, you will hear random alien voices which is pretty fun and adds to the whole alien space theme.

Reactoonz Slot RTP and Volatility

Reactoonz is a high-volatile slot machine. This means that you will have to arm yourself with patience if you want to catch those big wins in the game.

RTP of this slot stands at 96.51% which is around industry average and pretty standard for volatile slot machines. The winning potential of Reactoonz goes up to x4,750 total stake.

Reactoonz and Cascading Reels

Reactoonz slot machine doesn’t have a standard reel structure. Instead of a regular reel board, Reactoonz features a 7×7 grid and cascading reels. The wins are formed when you get a cluster of at least five symbols either horizontally or vertically. So as long as there are five symbols in a cluster touching each other, you have a win.

Cascading reels provide multiple chances for extra wins as one spin can be prolonged. Mainly, when you spin the reels and get a win, the winning symbols will explode and disappear while new ones will fall into the empty positions. The cascade continues as long as there are new wins formed. When no consecutive wins occur, the cascade ends, and you spin the reels again. The cascade also plays a big role in the features, as to activate some you will need to fill the meter with consecutive wins.


As for the symbols, Reactoonz slot comes with only alien symbols. There are no playing card icons we see in so many slot machines which is pretty refreshing. Anyhow, there are eight symbols altogether. Four of them are one-eyed aliens and these comprise the set of lower-paying icons. The other four are two-eyed aliens and they pay bigger wins. The purple two-eyed alien is the most rewarding icon of them all.

Quantum Leap Features

Reactoonz is all about filling up quantum meters and triggering some of the features. Now, when it comes to the Quantum Leap Meter on the right side of the screen, it can trigger five features. The meter is filled with consecutive wins and once it’s full it will award one of the features randomly and add it to the queue. All for features can be queued and if you manage to charge the meter the fifth time Gargantoon feature becomes active. Let’s see what are the first four features:

  • Implosion – this feature turns three to six symbols wild while at the same time destroying all adjacent symbols.
  • Incision – you get a wild symbol in the centre of the grid with two diagonal lines through the grid which will then transform into matching symbols.
  • Demolition – this feature will destroy all one-eyed symbols and all matching symbols.
  • Alteration – it will choose one random one-eyed symbol and all matching symbols and turn them into a matching icon.

When all of these four features are queued then the main Garantoon feature becomes active. Garantoon is the three-eyed monster alien you see on the right side of the screen. When his feature is active, the 3×3 monster symbol appears as wild on the reels replacing all the symbols. With each cascade, he moves on the grid becoming 2×2 symbol and then he divides into nine separate wilds which can bring quite big wins along the way!

Random Wilds, Fluctuating Symbol, and Giantoonz

Garantoon has one more role and that is randomly dropping four to eight wild symbols on the grid. This can happen after any non-winning spin and the feature is called Instability.

Giantoonz feature gets active when four matching symbols form a square cluster. This is when these symbols become Ginatoonz, that is, one 2×2 symbol which will double the wins.

Finally, there are Fluctuating symbols. Mainly, on each spin, a one-eyed alien is marked as a fluctuating symbol and if it becomes a part of a win it will leave two wilds behind creating more winning chances.

The Expert Verdict

All the features and reactions may seem a bit too much complicated. But once you start playing this slot, after a few sessions everything will come together and you will quickly get a grasp on it. Don’t let all the names and meters confuse you as this game flows pretty smoothly and everything will make sense once you get into the game.

All in all, Reactoonz is an excellent slot machine with plenty of action on the reels. The main goal is to get as many consecutive wins as possible as this is the key to activating all the quantum features. And when you are not doing that great, Gragantoon monster will randomly award you with some extra wilds to help you out with the wins. Play n’ Go managed to bring us an exciting slot with interesting and creative features exploding all around.
