Reactoonz Review

Released back in 2017, Reactoonz instantly became a worldwide hit, and it still remains one of the most-played Play’n Go games ever. With a fun alien theme and gameplay packed to the brim with bonus features, it keeps capturing the hearts and minds of thousands of gamblers up to date, and even though there’s already an official part two, players can’t get enough of the original Reactoonz slot.

About Play’n Go

Play’n Go is a provider with one of the largest portfolios out there, which consists of over 350 slots and still counting. It’s not just a quantity approach, as the studio has released tons of high-quality games, with a number of them having gained legendary status among players, including Book of Dead, Rise of Olympus, Fire Joker, of course, Reactoonz, and many more, which remain at the top of casino lobbies for years.

Theme, Video & Sound

We often think of aliens as scary, hostile, and willing to conquer our planet creatures, but that’s not the case with the Reactoonz slot game. The developers have taken a completely different approach, so the aliens here are jolly and friendly, and Reactoonz is what those extraterrestrial organisms are called.

Another thing that makes the Reactoonz game stick out from the niche of space-inspired slots is the cartoonish design, a very cute one, with colorful imagery and animations and an energetic upbeat soundtrack. The actions of the Reactoonz online slot take place somewhere deep in outer space, with the background image showcasing the dark endless cosmos, while the center is sitting a large 7x7 grid made up of bizarre adorable aliens, which we’ll walk you through in the next section of our Reactoonz slot review.

Game Symbols & Paytable

On the reels, we see alien creatures of different shapes and colors. Some are smaller and one-eyed, acting as lower-pays, and some are bigger and have two, which are higher-paying symbols. Plus, to the right of the reels, you can spot even a larger, three-eyed Gargantoon, floating in some kind of a UFO contraption, keeping track of your progress towards activating in-game modifiers and which itself appears on the grid only through the features.

Winning combinations are achieved in clusters of 5 or more matching symbols touching horizontally and/or vertically. After a payout, winning symbols get removed from the reels while the remaining ones fall down to available positions. Then, new ones are added from above to fill the gaps, and the process goes on until no new wins are scored.

Symbol xBet for 5 xBet for 7 xBet for 7 xBet for 8 xBet for 9 xBet for 10+ xBet for 12+ xBet for 15+
Low Yellow Toon 0.1x 0.15x 0.2x 0.3x 0.6x 0.8x 1x 3x
Low Green Toon 0.1x 0.15x 0.2x 0.3x 0.6x 0.8x 1x 3x
Low Red Toon 0.15x 0.2x 0.4x 0.6x 0.8x 1x 3x 10x
Low Purple Toon 0.15x 0.2x 0.4x 0.6x 0.8x 1x 3x 10x
High Blue Toon 0.5x 0.7x 1x 1.5x 2x 3x 5x 75x
High Yellow Toon 0.6x 0.8x 1x 2x 3x 5x 15x 150x
High Green Toon 0.8x 1x 2x 3x 4x 10x 25x 300x
High Purple Toon 1x 2x 3x 5x 8x 20x 50x 750x

In addition to these, there are also Wild symbols available, which substitute for any alien symbols in winning combinations. However, Wilds can only appear through the features.

Reactoonz Slot Bonuses & Special Features

When it comes to the features of the Reactoonz slot, there’s actually a lot to cover. There are random Wilds on non-winning rounds, extra Wilds added from wins, mega Gargantoon Wilds, multipliers, and four different random modifiers that trigger after collecting enough winning symbols in a spin.


When 4 instances of the same symbol appear adjacent to each other in a square shape, then they merge into one 2x2 Giantoonz symbol. Plus, such symbols acquire a 2x multiplier value, so combinations containing Giantoonz are doubled.

At the beginning of each spin, a random low one-eyed symbol is marked as a fluctuating symbol. If marked symbols participate in a win, they will leave 2 Wild symbols behind, added to the reels before a cascade.


Randomly, if a spin results in no win, there is a possibility that a random number between 4 and 8 of Wild symbols will be added to the reels for a chance to create a win.

Quantum Leap & Quantum Features

All winning symbols contribute to a special meter. Each symbol charges the Quantum Leap progress bar by one point, and it takes 25 symbols to fill up one segment of the bar. After a segment is filled, a random Quantum feature is added to the queue.

Up to 4 Quantum features can be stored and queued up, and charging the meter for the 5th time adds a guaranteed Gargantoon feature. The features trigger in succession after there are no longer new wins to be made. They are the following:

  • Implosion - transforms from 3 to 6 random symbols in view into Wilds and destroys all adjacent symbols.
  • Demolition - destroys all lower-paying one-eyed aliens in view.
  • Incision - places a Wild symbol into the center position and creates two intersecting diagonal lines through the grid, which then reveal the same randomly chosen symbol.
  • Alteration - selects a random lower-paying one-eyed alien and turns all of its instances in view into another random symbol.
  • Gargantoon - adds a 3x3 Wild symbol to a random position, which moves and splits with each cascade, first into two 2x2 Wilds and eventually into nine 1x1 Wilds.

Reactoonz RTP & Max Win

In order to play Reactoonz online slot, players need to set bets from as little as €0.2 up to a maximum of €100. It’s a standard Play’n Go betting range, and it should appeal to most, including both lower-stake punters and high-rollers.

There is a range of different Reactoonz RTP configurations available, meaning that you can come across significantly varying payback settings depending on where you play. By default, the return rate clocks in at 96.51%, which is above average. However, other available values are way below, namely at 94.51%, 91.49%, 87.50%, and 84.51%. Therefore, look through the rules and check out the Reactoonz demo slot before making a deposit at a casino.

The volatility is high, rated 10 out of 10 by the developers, so there’s great risk involved. The potential, however, is lower than you might have expected. The maximum you can get from a single spin is 4,570x the stake, which makes Reactoonz max win slightly beneath the standard level.

The 200 Spins Reactoonz Experience

We couldn’t skip past this iconic release and decided to give Reactoonz a test run of 200 spins. We set the bet to €1, enabled the autoplay, and crossed our fingers awaiting big wins to come. All we had experienced in those 200 spins though is the brutal level of the game’s volatility. Small payouts were in abundance, and so were the random Quantum features, yet not a single significant win was achieved. There were enough returns for us not to lose a substantial portion of our starting balance, and we had a fun session overall, but not really a fruitful one. We hope the game will treat you better!

Compatibility With Mobile Devices

The Reactoonz game operates under HTML5 technology, which means it’s fully compatible with handy platforms, including Android and iOS. You can play it on the go using a smartphone or a tablet and run the slot through any dedicated casino app or directly from a browser.

Reactoonz Slot Verdict

All said and done, there’s a reason why Reactoonz is one of the finest grid slots ever released. Play’n Go has really gone beyond the boundaries with this one. First of all, it’s the out-of-ordinary space theme that introduces a new take on extraterrestrial life. The second, and most important, is the gameplay, which doesn't let you have a dull moment throughout the session. Overall, the cute aliens, colorful imagery, and dynamic soundtrack really strike the right note and together with the action-packed gameplay make for a delightful gaming experience.
