Reactoonz Slot Game 

Reactoonz is a unique 7-reel slot from Play’n GO, featuring adorable aliens, multiple bonus features, and big prizes! You could win more than 4,500x your bet, and the Quantum features can transform symbols to make winning combinations easier to form. And as if all that weren’t enough, the cascading feature lets you string wins together, leading the way to increasingly higher payouts. 

Theme & Symbols

The Reactoonz slot game has an innovative design and structure. The 7x7 grid is filled with cute aliens of different colours, from red and purple to yellow, giving you 49 symbols to play with. 

Each alien character has its own design and animations, whether they yawn, look excitedly at the others around them, or blink. The music and sound effects during the game suit the theme perfectly — you’ll hear the aliens make sweet sounds from time to time, which makes Reactoonz more immersive.

The highest-paying symbol in the game is the Pink Alien, which awards 750x your stake if you match at least 15 on the grid. The Green Alien is next: land 15+ for 300x your bet. Other symbols include Orange, Blue, Purple, Red, Green, and Yellow aliens. The Yellow is the lowest-paying symbol, offering 3x your wager for 15+. 

The Basics: How to Play Reactoonz Online Slot


In Reactoonz, you need to match at least five symbols that connect vertically or horizontally to win. Use the SPIN button next to the grid to spin the reels, and pick one of the wagering options at the bottom of the screen to select your bet. Your current balance, bet, and winnings are displayed during gameplay. 

The Reactoonz slot online features cascading reels: all winning symbols in a combination pop and drop out of the 7x7 grid, and new symbols fall in to replace them. And if you get another winning combo on your next spin (and beyond), the cascading will continue until you can’t create another combination. 

Any wins you accumulate during the base game add to your Quantum Leap charge meters, and help them increase one at a time. Filling a charge meter triggers one of multiple random Quantum features. While there are no Reactoonz slot free spins available, Play’n GO has added other fantastic bonuses instead.

Reactoonz Slot RTP & Wager Limits

Reactoonz’s average RTP is 94.51%, and it’s classed as a high-volatility game. You can start wagering on spins from as little as £0.20 up to £100. The biggest prize on offer in Reactoonz is 4,570x your bet. 

Reactoonz Bonus Features



One of the Wild symbols in the Reactoonz online slot takes the form of a swirling ball of blue and purple light. This substitutes for all other symbols. 

The Gargantoon is another Wild in the Reactoonz slot UK, and is unleashed on the grid when you fill the Quantum Queue. This 3x3 creature substitutes for every other symbol. 

The Gargantoon also splits and moves position with every cascade that occurs while it’s on the grid. It creates two 2x2 Wilds after its first cascade, then splits into nine individual Wilds on the next. 

Quantum Queue 

The Quantum Queue appears to the left of the reels. It fills with each combination you create, displaying the winning symbols and the prize. 

Instability Feature

There’s a chance that the Instability feature may occur on any initial non-winning spin. When it does, the Gargantoon drops between four and eight Wilds onto the grid to increase your likelihood of making winning combinations.


Match four normal symbols next to one another in a square pattern to automatically create Giantoonz — these are bigger versions of the aliens that double all winnings they’re involved with. 


For each spin, a one-eyed alien is randomly selected to be a fluctuating symbol. Any fluctuating symbols that form part of a winning combination leave two Wilds in their place. 

Quantum Leap

The Quantum Leap charge meters charge with each win. After you win 25 symbols, a random Quantum feature is added to the queue. You can queue as many as four Quantum features, but the Gargantoon feature is added on your fifth charge. 

Quantum Features

There are four Quantum features in the Reactoonz mobile slot:

  • Implosion: Turns 3 - 6 symbols Wild and destroys adjacent symbols.
  • Incision: Slips a Wild into the centre of the grid and forms two intersecting diagonal lines across the grid. Both lines show a matching randomly selected symbol. 
  • Demolition: Destroys all one-eyed symbols and their matches. 

Alteration: A one-eyed symbol is chosen at random and every matching symbol is transformed into a different one.
