Reactoonz is one of those slots you will always find yourself returning to. Released 01.10.2017, Play’n GO takes you on a journey to a parallel universe full of colourful little aliens. Played on a 7x7 reel set, Reactoonz is just as thrilling to play as it is colourful. 

The minimum bet allowed is € / $0.2 up to the maximum bet per spin of € / $100. While the little aliens look cute and friendly, the one you really want to get on the good side of is Gargantoon, who is not so cute looking, let’s say. 

Making the use of a cluster pay mechanics, the online slot comes with a 96.51% RTP and provides players with a chance to win up to 4,750x their stake placed. Reactoonz is considered a highly volatile slot game. 

Reactoonz, Bonus and Features

Reactoonz not only has beautiful graphics but it also offers plenty of enticing features which will keep your hair standing on end… or maybe that is from no gravity up in space, who knows!?


Watch out for the Gargantoon if the Quantum queue manages to reach him. He will grow into a 3x3 sized monster and appears as a wild and substitutes for all symbols. 

On the Initial non-winning spins, do not be disappointed. There is a chance that the Gargantoon is feeling slimy and can drop up to 4-8 wild symbols onto the reels. 

Quantum Leap

To the left-hand side of the reels, you will see empty meter under the Reactoonz writing. With each win made this will add to the meter on the left. 

One thing you will notice with this slot game is that the symbols cascade. This means that every time you get a winning combination, these symbols will disappear allowing new symbols to drop down, giving you more chances to win. 

Quantum Features: 

The Quantum comes with four main features. These four features do not have any effect on the wild symbol. See below to find out more about each one. 

  • Implosion: Implosion is an orange fireball symbol, which transforms 3-6 symbols into wilds, as well as obliterating all adjacent symbols too. 
  • Incision: Incision is a blue fireball symbol and cuts a wild symbol into the centre of the grid, creating two unusual diagonal lines. The diagonal lines will then turn into the same random symbol. 
  • Demolition: Demolition is a red fireball symbol which destroys all one-eyed monsters, and any matching symbols present on the grid. 
  • Alteration: Alteration is a green fireball symbol which allows you to pick one, one-eye monster randomly. Once you have chosen your monster all matching symbols on the grid will turn into the chosen symbol. 


To form a Glantoonz, you need to have 4 matching symbols next to each other to form a square shape. Once you have formed into a Glantoonz in any winning combination that the Glantoonz are joined to will double the winnings.  


 In each spin, one type of random one-eyed monster symbol is marked as a Fluctuating symbol. This means that if any of the Fluctuating symbols become part of a winning set, then they will drop 2 wilds, which substitute for any symbol.
