Should You Play Reactoonz?

Absolutely. 100% yes! There are various reasons why Reactoonz has become a much-loved game for many players online. Its excellent graphics, its ideal soundscape, the special features you can trigger, and the inviting betting range. You’ll love spinning the reels and clustering alien symbols to form wins. It’s one of the best for spaced-themed slots at online casinos. Play’n Go has truly crafted a compelling and satisfactory slot with Reactoonz.

As well as the base game, you can benefit from wilds occurring via the Quantum Leap function, symbol replacement, symbol destruction, and even giant-sized symbols. Please read through this review of the game to find out all about it.

While most online slot games utilise reels and rows for their setups, Reactoonz is a different entity. Instead, you will see a grid that stands at 7x7 large. Upon this grid, the symbols appear, and the wins are formed. As a result of this layout, there aren’t any paylines involved in the Reactoonz online slot, either.

The wins are formed when you create clusters of five or more matching aliens on the grid. These can gather in clusters of horizontal or vertical areas, but not diagonally. Placing a bet is the first step when playing this Play’n Go release. This developer is known for making its slots simple to access and play.

As soon as you load the slot up, you can see that various bet amounts are running along the bottom of the screen. Thus, all you need to do to choose your wager is navigate through these. Arrows at either side allow you to see the different values, which start from the minimum of £/$/€0.20 per spin. They increase through multiple stages, reaching a maximum of £/$/€100 per spin.

As with many online casino slots, you can start playing the game properly once you select your preferred wager. Press the green button in the bottom-right corner, and this sets the reels off spinning. If you prefer, you can utilise the yellow button next to that one for the autoplay function. This allows you to set the reels off, spinning up to 100 consecutive times.

You receive a payout upon matching five or more identical alien symbols in a cluster on the grid. Each symbol has its payout for you to benefit from, and you can win up to 750x your stake from these in the base game round. The symbols can contribute to a winning cluster if they touch horizontally and vertically.


Imagine visiting an alien planet and coming face-to-face with some of the xenomorphic creatures residing there. You don’t have to imagine it anymore because Play’n Go brings those aliens to your screen in the Reactoonz online slot. You’ll get to see how intelligent the lifeforms on other planets really can be. These aliens are so smart that they can even reward you with monetary payouts!

The symbols grid is present against a backdrop of space. Thus, you’ll see dark colours, including deep blues and purples, against the expanse. Flickers of light from distant stars occur now and again, bringing more attention to the slot’s base theme.

To the right of the game’s reels, you will see a big alien in its own flying saucer-like vehicle. Rest assured; he is not ignorant of the goings-on of your gameplay. There’s more from him later!

Reactoonz was released in 2017 and features the usual exceptional graphics and animations from Play’n Go. That’s why it can be found in the game lobbies of many of the best international casino sites. All the symbols appearing on the grid have had some stunning visual work done by the developer.

The symbols each come with their personality. You’ll find yourself entertained by them from the minute you start playing. Included in the grid are symbols and payouts in the following formats:

  • Pink Alien: 15+ symbols pay out up to 750x your overall bet.
  • Green Alien: 15+ symbols pay out up to 300x your overall bet.
  • Orange Alien: 15+ symbols pay out up to 150x your overall bet.
  • Blue Alien: 15+ symbols pay out up to 75x your overall bet.
  • Purple Alien: 15+ symbols pay out up to 10x your overall bet.
  • Red Alien: 15+ symbols pay out up to 10x your overall bet.
  • Dark Green Alien: 15+ symbols pay out up to 3x your overall bet.
  • Yellow Alien: 15+ symbols pay out up to 3x your overall bet.

It is also key to point out that four matching standard symbols in a square shape automatically form Giantoonz. Wins are doubled if these are involved in a cluster.

Design and User Experience

The overall design of Reactoonz offers a wonderful interface. The developer’s graphics and animations shine through, which it is well-known for in the industry. It’s not all about the visual side of things, though.

The game has some enjoyable sounds playing out while you’re betting (and winning). Everything is provided in a sci-fi vein, so you will always get the feeling behind the theme. Now and again, a few alien critter sounds will also play out.

Things enter crazy mode when you start forming wins and triggering the slot’s special features. Not only do these make the theme much more effective, but they provide endless entertainment for you. Without a doubt, Play’n Go has crafted something exceptional where Reactoonz is concerned.

Reactoonz Bonuses and Free Spins

The Reactoonz game doesn’t include anything like scatters or base wilds. That doesn’t mean it is devoid of any special features, though. It has plenty of these for you to experience and enjoy.


On any initial non-winning spin of the game, there is a chance for the Gargantoon (the giant alien to the right of the grid) to drop between four and eight wild symbols onto the grid. These set about substituting for all other base alien symbols in the game, thereby potentially forming wins.

Quantum Leap

At the top-right side of the slot, you will see the Quantum Leap meter, which charges up with every winning cluster formed. After collecting 25 symbols in these clusters, a random Quantum feature is added to the line. Up to four Quantum features can be lined up, and the features activate when no more wins are present. They include the following:

  • Implosion – Transforming between 3 and 6 symbols into wilds and destroying all adjacent symbols.
  • Demolition – Destroys all the one-eyed alien symbols.
  • Incision – Cuts a wild symbol into the centre of the grid and creates two intersecting diagonal lines through it.
  • Alteration – Chooses a random one-eyed alien symbol, and all matching symbols turn into another.


If the Quantum line on the meter reaches the Gargantoon, the 3x3-sized symbol appears as wild and places itself anywhere on the grid. It then divides and moves with each cascade created, first becoming two 2x2 wild symbols and then nine individual wilds.

  1. Sign up for an account at your chosen Play’n Go casino.

What Is Reactoonz’s RTP?

The Reactoonz online slot incorporates an RTP rate of 94.51%, which sits somewhat below the industry average for video slots of 96%. You’ll need to bear this in mind when you are choosing your bets in the game.

Furthermore, it is a high variance slot, so you can expect larger payouts, yet these will come at less frequent intervals. That’s also something to remember when playing the game, so you should ensure a bankroll that caters to the lower RTP rate and the high volatility level.

How Can I Win at Reactoonz?

Winning the game is easy. You hit the play button and wait for a cluster of five or more matching alien symbols to come into view in a cluster. Of course, there is nothing to guarantee that a win will come at any specific time. That’s the same in any game release, even the top casino games online. Yet there are certain hints and tips that you can take on board when playing Reactoonz to heighten your chances.

Our Top Tips and Tricks to Winning

  • Multiple wins can occur from a single round, thanks to the avalanche wins. Try to make the most out of these with a decent bet.
  • Don’t go all out with a huge wager. Most players don’t have a massive bankroll, so ensuring you suit your bet to your budget is key.
  • The special Quantum Leap features can be helpful when they hit, but don’t go thinking these will come around frequently.
  • Take note of the RTP rate and variance level of Reactoonz to determine the wager you place in each round.

Our Personal Experience Playing Reactoonz

I first played this Play’n Go game shortly after it launched in 2017. The cluster wins feature was quite new to the slot scene at that point. I instantly loved it because it did something different to the standard five-reel, three-row setup. With the addition of various specialities, thanks to the Quantum Leap function, Reactoonz stood out to me in multiple areas. I’m sure that that will be the case for you too, and here are some pointers about the game for you to keep in mind:

  • The game includes several special features which are unique to it.
  • Reactoonz has a high variance, which may suit high-stakes gamers.
  • There is a nice range of betting amounts to select from in the game.
  • There is a maximum win possibility of 4,570x your stake in Reactoonz.

You could choose to play one of many other online slots if the space or alien theme is for you. Below, you can see some of our recommended slot releases.

Notre-Dame Tales

Why not try this online slot from the Yggdrasil brand, which tells the tale of The Hunchback of Notre Dame in its way. It has a standard six-reel, four-row layout, which can expand to six rows. Notre Dame Tales is a medium to high volatility game featuring a 96% RTP rate and 25 paylines to win on (which can increase to 40). From the free spins, bonus games, multipliers, random wilds, Gigablox, and more involved in the slot, you can win up to 3,730x your bet.

Gates of Olympus

It’s never a bad day when you get to play a game from Pragmatic Play. Fortunately, Gates of Olympus is one of the developer’s best releases, launching in 2021. It offers a pay-anywhere setup and the chance to win up to 5,000x your bet alongside high volatility. The game utilises the base theme of Greek mythology whilst offering many special features. This includes free spins, multipliers, avalanche wins, progressive jackpot payouts, and scatters.

Age of the Gods: God of Storms

The online world provides you with access to many Playtech slots, and this is one of the developer’s best. Part of the ‘Age of the Gods’ series of games, this is another one that offers you the opportunity to win a jackpot payout. A standard five-reel, three-row layout is present, as are 25 paylines. God of Storms also has an RTP rate of 96.14%. During gameplay, you may experience its bonus game, multipliers, respins wilds, and even receive one of the inbuilt progressive jackpots.

Our Final Thoughts

If we were to recommend an online slot from Play’n Go, the Reactoonz release from 2017 would be the one. It has a little bit of everything, offering excellent graphics and animations, a top-quality soundtrack, an appealing base theme, inviting inbuilt special features, and so on. You’ll get endless hours of entertainment out of the game, especially if you’re a high-stakes player. Try playing it for free here before proceeding with real money wagering.
