Reactoonz Slot RTP, Details & Wager Limits
The Reactoonz slot is played on a 7×7 grid with a Cluster Pays engine. A winning combination is formed by getting 5 or more matching symbols as long as they touching, either horizontally and/or vertically.
You can play Reactoonz from 20p to £100 per spin and your aim is to round up clusters of energetic extra-terrestrials.
It comes with an Auto Play function where you can choose between 10 and 100 spins. You can stop the Auto Play on any win, if a single win exceeds an amount or if your balance increases or decreases by your determined number. It’s quite easy to use this if required.
The Reactoonz RTP is 96.51% and it’s a high variance slot, 10/10 according to Play‘n GO. In terms of the max win, this can reach an impressive 4,570 x your stake on every spin or cascade.
Theme – round up energetic extraterrestrials
Visually, the Reactoonz slot takes you to a parallel universe and has a cute, alien theme. With cartoon style graphics, it has a plain, dark blue background. You will see highly animated aliens drop from the heavens to fill the 7×7 grid.
Winning alien symbols sees the winning clusters instantly teleported away to be replaced with new space invaders. The soundtrack has a synthetic feel.
Symbols on the reels include 4 lower-paying aliens, 4 higher-paying aliens and a vortex wild. The highest value symbol is the pink alien that gives you 750 x your stake for 5 across a payline.
The vortex wild simply replaces all symbols to help form winning combinations.

Reactoonz Mobile
You can play Reactoonz on desktop, mobile and tablet devices as Play ‘n GO has created it using HTML5 technology. The 7×7 grid works well, particularly for smartphone devices.
Reactoonz Bonus Features
In Reactoonz, the cascading reels engine is central to the action which allows you the win again and again from each spin. Each win charges the Quantum Leap meters which leads to 5 more bonus features. There’s also 2 other features which can occur in the base game. In total, there are 9 bonus features.
Cascading Reels feature
Reactoonz uses a Cascading Reels feature with symbols dropping down into the 7×7 grid. You can form winning combos when you get 5 or more of the same symbol connected in a cluster (either horizontally or vertically).
When you get a win, the contributing symbols are removed with new symbols dropping to fill up the empty spaces in the grid. The Cascades continue until you no longer get a win but you can win time and time again from every spin.
Quantum Leap features
When you do get a win, you will increase the 5 Quantum Leap charge meters 1 by 1. When a meter is charged, 1 of the quantum features is added to the queue randomly. Here’s a look at what the features offer:
- Implosion feature: 3 to 6 symbols are transformed into wilds with adjacent symbols also being destroyed.
- Alteration feature: 1 random low-value symbol is chosen with all instances of that symbol transforming into another symbol. If there’s no low value symbol on the grid, a high value alien will be chosen.
- Demotion feature: all instances of low value symbols are destroyed and removed from the grid.
- Incision feature: a wild is cut into the centre. This then creates 2 intersecting diagonal lines through the grid. This will then display the same randomly chosen symbol.
When all 5 charge meters are charged fully, the Gargantoon feature is added to the queue. Here, the Gargantoon adds a 3×3 wild randomly on the grid. With each cascade, the Gargantoon divides to become two 2×2 wilds. With the next cascade, it divides again into nine (9) 1×1 wilds.
If you don’t get a win here, 1 randomly triggered quantum feature is triggered. During the features, you can charge the charge meters which gives you the opportunity for more quantum features. The charge meters only reset if no more winning combos are formed.
Instability feature
The Gargantoon can randomly drop 4 to 8 wild symbols onto the grid if you have a non-winning spin. This is known as the Instability feature.
Giantoonz feature
Reactoonz also benefits from a Giantoonz feature. This is played when 4 matching symbols adjacent to each other in square shape (2×2) appear. This will form Giantoonz, which means wins are doubled (i.e. 2x multiplier) in any winning combination.
Fluctuation feature
Finally, there’s a Fluctuation feature. 1 random low-value symbol is marked as the fluctuating symbol on each spin. If it’s part of a winning combination, it will leave 2 wilds behind on the grid.
Reactoonz Review Summary – electrifying experience
The Reactoonz slot may sound complicated but it’s rather simple once you get playing. It is fast-paced, fun and also very high variance as you win up to 4,570 times your stake on every cascade/spin.
The best chance of winning big is to get the high-value pink alien prominently on the reels alongside wilds with the Giantoonz feature which applies a 2x multiplier to your outcome.
I really like Reactoonz. It’s not traditional in the slightest which is a good thing but offers lots of action and the potential for out of this world wins if your luck is in.

Reactoonz FAQs
The Reactoonz slot RTP is 96.51% which is pretty high for a slot game. The wins are distributed evenly in the game which the bigger wins coming from the various bonus features you can activate.
The most you can win from a Reactoonz spin/cascade is 4,570 x your total stake. Being a high variance slot, most wins will be of a smaller nature so you need to be patient and lucky.
Wins increase the charge meters with a full meter add a $1 to the queue. They transform symbols into wilds, transform a low-value symbol, destroy a low-value symbol and add a random symbol to the grid. Charging all 5 meters brings the Gargantoon feature into play where it divides into more wilds.
