Introducing Reactoonz

Reactoonz is a cute and quirky online slot from Play n Go, which features a fun match-5 format. It's one of the studio's top-performing titles, and continues to be a huge hit among players.

The developer has also launched a sequel, which features a whole range of new bonus features. You can also give the Reactoonz 2 free play slot right here at Slots Temple.

Reactoonz Slot Graphics

The symbols on the reels of the Reactoonz slot don't remain inert, as they usually do with these types of games. But this collection of quirky characters, some with one eye, and the others with two eyes, regularly peer at their companions around them.

Take too long to start spinning the reels, and one or another of them will even begin chatting, while the others blink and keep looking around. It's fascinating to watch, and creates an instant engagement with the game, even before you start spinning the reels.

Reactoonz is a dynamic and interactive slot. Even though it was released in 2017, it remains one of the best designed games out there, as it really engages players.

How to Play the Reactoonz Demo

The controls for Play'n GO's Reactoonz slot are very simple:

  • All of the controls are located in the menu marked by three horizontal lines - aside from the spin button (that's the big green button)
  • When you click on it, you'll be taken to the bet settings where you can wager between .20 coins and 100 coins per spin.
  • Here is where you can also set your autoplay options, with loss and win limits available.
  • Scroll across to Settings to adjust the volume, spin speed and more
  • The paytable is an animated explanation of how all of the features work and how much the symbols are worth
  • Scrolling to Game Rules is a more in-depth, text-based explanation of the gameplay

Setting Loss Limits

If you're going to be using the Autoplay, it's important to be mindful about your loss limits. Don't just set it to the maximum; make sure it's a value that you would be alright with losing.

Ensure that you keep a bit of your balance back so that you can walk away with some winnings.

RTP & Volatility of Reactoonz

The RTP (return to player) of Reactoonz is 96.51%. In terms of new slot releases, this is one of the more generous payout percentages.

Most newly released online slots range from 96% to 96.5%. So, Reactoonz slightly exceeds this.

Variance Level

It is also a high volatility slot. This means that you might not land prizes all that often but the wins you do land are likely to be more generous than average.

How To Win on Play'n GO's Reactoonz Slot

If Reactoonz operates using the Cluster mechanic. As such, groups of five or more  symbols need to be matched vertically and horizontally to score wins. Matching symbols must be adjacent, either on rows or on reels, and diagonals don't count.

The symbols involved in wins disappear from the reels, in a mechanic variously known as Cascading Reels, Avalanche Reels, Tumbling Reels or just plain Reactions.

Wild Symbols

Represented by a whirl of yellow light, the Wild doesn't just land on the reels, but has to be generated in some way.

With every spin of the reels, you'll see that one randomly-chosen one-eyed symbol is surrounded by a glow of light. If this low-value symbol goes on to make up part of a winning combination, it will generate two Wilds in the spin that follows.

There is also Gargantoon. He can generate Wilds at any time as well, simply by blasting between 4 and 8 of them onto the reels at random.

Once 25 symbols have been collected in the Meter, the energy stored within it is transferred across to the other side of the reels, where it's collected in the Quantum Meter.

There are four Quantum Leap Reel Modifiers:

  • Implosion: This will transform anything between three and six symbols on the reels into Wild symbols.

  • Alteration: When the Alternation modifier is triggered by the Quantum Meter, the game selects one of the low-value one-eyed alien symbols to change into a different symbol.

  • Demolition: Demolition clears away all of the one-eyed symbols from the reels, as well as all matching symbols.

  • Incision: Incision puts a Wild symbol right at the centre of the grid, and places matching symbols across the diagonal lines, potentially creating winning combinations as it does so.


The Quantum Bonus in the Reactoonz demo slot that all players want to land is the Gargantoon, but he only really comes to life once all the other four bonuses have been completed. And you'll still need to spin up another 25 symbols in the Reactoonz Meter.

Gargantoonz Bonus

If you're lucky enough to spin up Gargantoon, he leaps onto the reels, taking up 3x3 spaces, and acting as a Wild, so he can generate some spectacular wins.

The Gargantoon then divides itself into two separate 2x2 icons, which again can generate some big wins.

Finally, the Gargantoon morphs into nine individual Gargantoon Wilds, giving one last chance to generate some big cash payouts for you.

Instability Bonus

Periodically, following any non-winning spin this bonus will be triggered. Here, Gargantoon will throw between 4 - 8 Wilds onto the reels, in the hope of spinning up some winning combinations for you.

Enjoy Reactoonz? Why Not Try...

Reactoonz is the kind of online slot that will make you want to play even more. So, if you're in the mood for more great slots after you Play Reactoonz, here are some of our top suggestions.

The Reactoonz Family

If what you're looking for is something much closer to the original Reactoonz, there are a few options. We understand, it's really difficult to replicate the quirky aesthetic - luckily, Play'n GO has created a couple of spin-offs.

Reactoonz 2

This is a direct sequel to Reactoonz. While the game aimed to be an enhanced version of the original, it was a bit of a flop.

Even before the slot was released, it was criticised by players for having a less generous top prize than Reactoonz. Fortunately, Play'n GO realised the error of its ways by upping the max win to just over 5000x. 

However, that didn't really save Reactoonz 2 from not being well-received by players. The game has a slightly lower RTP and less rewarding features.

For example, you need to collect 55 symbols before you can enter Level 1 of the bonus. So, it's much more difficult to begin landing modifiers than it is in the original game.

There's also the issue of the gameplay being too complicated. There are 'fluctuating' symbols that can add wilds of the reels - but, it's pretty hard to follow exactly what's happening.

So, this slot is really only one that we'd recommend for die-hard Reactoonz fans. It's the kind of game that you'd be tempted to try just to experience the Reactoonz brand from another angle.

Dr Toonz

In Play'n GO's Dr Toonz slot, you're looking at a more standard slots experience. It hasn't got cluster pays; instead, there is a 4096 ways to win format. So, this game may be a good option for more classic slot fans.

The Quantumeter is present in Dr Toonz, and it's much easier to charge than in Reactoonz 2. Here, it is charged by landing individual winning symbols than being based on the number of cascades, and there are three features available:

  • Quantum Wilds: up to 6 wilds are added to the screen
  • Metamorphosis: up to 8 symbols are transformed
  • Disintegration: all low-paying symbols are removed and replaced with two high-paying symbols. This increases the number of winning ways up to 26,144.

On top of all this, there's a free spins round. The top prize is also an impressive 22,000x.

Overall Review

This online slot is one of the most innovative and unique games released in recent years, so you get to enjoy the cascading reels and other features right from the very first spin. Plus, Reactoonz free play boasts the same great graphics, soundtrack and interstellar bonus rounds.

Always Entertaining

Reactoonz is that rare kind of slot where it feels like there's always something going on. There are cascading symbols, the bonus meter that charges as you land wins, the colossal symbols and the multipliers all going off at the same time during the base game. On top of this, you can even land the Instability Bonus to add wilds to the screen.

Instability Bonus

Despite everything that's happening, the game doesn't feel too crowded or overwhelming. It's a great balance that manages to keep you entertained without making the gameplay too complex.

Fun Bonuses

The bonuses really stand out, creating new winning potential in different ways. There's something very exciting about watching the bonus meter charge and collecting new features that will be unleashed.

Of course, some of the features are much better than others. For example, Alteration rarely helps to make winning combinations while Incision and Implosion are where the big wins lie.

Good Winning Potential

The near-constant triggering of features led to plenty of wins. During the base game, it was rare to trigger a prize worth more than 10x but the bonus round brought some impressive payouts - especially when Gargantoon made an appearance.

So, if you're looking for a great online gaming experience that truly offers non-stop action, then Reactoonz from Play n Go is the ideal game for you.
