Reactoonz by Play’n GO - Online Slot Review

If you're familiar with Play'n GO slots, this one may remind you of their previous popular cluster game – Gemix. The 7x7 structure, winning clusters, and charging the meter to release features proved highly successful. In Reactoonz, there's even more!

Aside from a wacky, lively theme, there is a load of entertaining events that perfectly align with the somewhat grotesque atmosphere. Everyone will want to meet the star of the show – Gargantoon because when he steps in, coins start raining!

How To Win On Reactoonz Slot – Features & Mechanics

Scoring base wins is straightforward. Out of the total 49 symbols visible on the screen, you need to match at least 5 adjacent horizontally or vertically. That first win becomes a starting point for a cascade, meaning that winning symbols will disappear and more will fall to fill blank spots.

Typically for cascading grid slots, individual wins might seem insignificant. However, a cumulative amount from several consecutive cascades will compensate for that feeling.

Winning on small clusters of low-paying symbols will usually pay out less than your stake, but landing those juicy wins consisting of top-value ones can be extremely rewarding. Achieving a cluster of 15+ of the top symbol pays 750 times the bet.

Titular monsters take part in nearly all the features. It's great that Play'n GO didn't put them in only for the visual aspect.

Giantoonz, Fluctuation, and Instability

Whenever four matching creatures land next to each other, forming a square, they will merge and acquire an x2 multiplier. All wins with the Giantoon will be doubled.

Fluctuation occurs when a random one-eyed (low-value) symbol is marked at the beginning of every spin. If any instance of that symbol becomes part of a win, it will leave behind 2 Wild symbols.

Instability may kick in on any non-winning spin. The great Gargantoon will wake up and drop from 4 to 8 Wild symbols in random positions.

Quantum Leap

A mysterious device sits next to the reels, holding powerful energy. Five segments will start filling up with every win, beginning from the leftmost one. Each filled piece becomes active and ready to unleash its potential. Once the cascading sequence is over, features will trigger one after another.

Alteration – chooses a random one-eyed symbol. All instances of that symbol turn into a different one.

Demolition – destroys all visible one-eyed symbols.

Implosion – chooses 3 to 6 symbols and transforms them into Wilds, destroying all adjacent symbols.

Incision – places a Wild symbol in the center. Two intersecting diagonal lines run through the screen, leaving a matching symbol behind.

Gargantoon

You may notice that the Quantum Leap meter has five segments despite only four features available. Filling up the fifth one will discharge the power of the Gargantoon.

He will teleport onto the reels as a colossal 3x3 Wild symbol. After the first cascade sequence concludes, he will split into two 2x2 Wild symbols and, after that, into eight single Wild symbols.

It's crystal clear that the first two respins will be guaranteed multiple wins since you only need 5 symbols in a cluster. The last one is also likely to continue delivering with so many Wilds simultaneously on the reels.

Reactoonz Graphics & Audio

I always appreciate a unique approach to delivering the game visually. Play'n GO created a living, breathing world enclosed within seven reels. The creatures brilliantly split into one-eyed (low value) and two-eyed (high value), with the most powerful Gargantoon having three eyes. The design is full of rich, glowing colors supported by numerous flashy animations and effects.

World of Reactoonz constantly feels alive, with random monsters looking around, winking at the player, or shaking with anticipation of the next spin. And that's only when the game is idle. Once you start winning, bursts of energy begin flowing from symbols to the Quantum Leap meter, and the entire screen lights up with lucid explosions when features kick in.

The audio track is composed of various spooky sounds intertwined with random gibberish of the monsters and Gargantoon's snoring when there is no action. Effects go together nicely with the outer space atmosphere. I always like the enjoyable sound of symbols landing on the screen, and I'm pleased with the impression of bursting bubbles used in this case in Reactoonz.

Reactoonz On Mobile

This slot looks absolutely phenomenal in both portrait and landscape orientation. The latter is, of course, nearly identical to the desktop view. When you hold your phone straight up, the reels nicely fill the entire screen, almost touching the side edges. The Quantum Leap meter and win history panel sit below, with the spin button conveniently in the middle. It's a good call to remove the Gargantoon in this view, as he plays a strictly visual role rather than a functional one most of the time. Of course, he will still jump onto the screen when the feature is triggered.

Final Thoughts

For me, it's not a mystery why Reactoonz has become an iconic grid slot. An original theme, advanced graphics, and a friendly feel are the elements I love to see in a game. Sprinkle that with various features and tremendous max win potential, and you have yourself a hit.

This casino game has gained so much popularity that Play'n GO decided to release a sequel, so be sure to check out Reactoonz 2, where Gargantoon's power grows beyond all reason!
