Reactoonz Theme and Symbols

Set in a galaxy far, far away from where 49 little aliens are either zapped into oblivion or up-sized to the large version of themselves for your gambling pleasure Reactoonz has one mission for you should you choose to take it. On – have some fun!

Set against an easy to read blue galaxy scape Reactoonz is a colour overload. The screen is split into three main sections. The far left is the Reactoonz win chamber, where your winning payouts are tallied up. This is useful as it keeps a running counter of the number of symbols you’ve cleared (show as 5x or more) and their relevant payout value (from 0.10 per symbol). 

The centre is the main game screen, where the reels and paylines are offered up as a massive 7x7 grid, where the original Energoonz was a mere 5x5! This is where you will have to keep a close eye on those mumbling aliens, both the one-eyed and two-eyed variety, plus an absolute explosion of lights and bedazzlement as the cascading symbols fall and casino bonus features are triggered. 

The far-right side of the screen houses the Quantum Leap Charge Meter, the meter that builds up and up and up over a series of wins to unleash the mighty Gargantoon (don’t you love wordplay) upon the game grid!

If you’re not sure who Gargantoon is, he is the rather crazy looking three-eyed, a multi-horned alien trapped in a suspension beam just below the Quantum Leap Charge Meter. 

Unlike other online and mobile casino slots, there is no throwback or hat tip to the early days of the slot machine here, with fruit symbols or playing card characters like the Jack, Queen, King or Ace filling up the reels. Every one of the 49 symbols slots is filled with one of two alien variants: one-eyed dopes or their cooler two-eyed cousins.

The one-eyes are the underlings with no discernible features other than their specific colour palette. At the same time, the two eyes are decked out with horns, expressions and most notable of all, giant eyebrows.

Our honest review of Reactoonz

Special Features of Reactoonz

The Reactoonz slot might have a limited if not colourful set of characters for you to enjoy, but what it lacks in the ensemble certainly makes up for in features and scope!

Release the Beast

The big one to play for the chance to yell, “Release the Gargantoon!” In reality, it’s less than cool than that but still fun nonetheless. Charging up the Quantum Leap Charge Meter to full capacity (it has five levels) will teleport the trapped Gargantoon onto the reels, where he takes up massive 3x3 slots on the 7x7 grid acts as a Wild. 

After the wins are tallied, he splits into two 2x2 Wilds that appear randomly on the 7x7 grid. Again this gives you a nice boost to your potential wins as they fill a large portion of the total grid, and keep in mind that wins count in all directions! 

Gargantoon’s third and final form is to split into nine Wild mini symbols and fill the grid for your winning pleasure. With the total game area only 49 symbols, that is an insanely high Wild coverage and helps boost your win tally before the end of this feature! No cascading win on this free play slot?

No problem! Any non-winning spin, there is a chance for a Gargantoon to drop between 4-8 Wild symbols onto the 7x7 grid at random.

The Road is Long

En route to releasing the Gargantoon, you will have to make your way through charging up the first four levels of the Quantum Leap Charge Meter. Each time you fill one of the first four meters, you will activate one of the following features at random:

  1. Incision – When triggered, it centres on the middle symbol and flares diagonally in all directions, cutting a big X across the screen. After settling, the affected symbols have all turned into a new single character. 
  2. Alteration – When triggered, it targets a random one-eyed symbol and alters all of its kind into a new single symbol. If there aren’t any one-eyed symbols, it will target a two-eyed one, so you don’t miss out on the potential win! 
  3. Implosion – When triggered, it sets off a small localised explosion that transforms 3-6 symbols into Wilds but destroys the symbols surrounding them. 
  4. Demolition – This feature destroys all one-eyed symbols on the grid and all matching symbols. The aftermath of this, given this, is cascading slot machine, can be a fantastic set of winning paylines!

If you’re not 100% sure how each feature works during the game, the name will come up as you trigger the feature to read up on it in the rules menu, which has complete descriptors for all aspects of the game you can play at the best online casino sites!

But That is Not Everything

  • If you thought that was all this feisty 7x7, wins pay all ways the cascading slot had to offer; you’d be sorely mistaken! Play’n GO has padded the experience with some other nifty spin-by-spin features that don’t require you to do anything special to reap the reward – other than having the patience, that is… 
  • Almost a flux capacitor – a random alien type will be tagged each round with the fluctuating market. This will put a pulsating blue and purple glow around it. Should these fluctuating symbols make up a winning payline, they leave behind two Wild symbols! 
  • Buff aliens – match four adjacent symbols, and they morph into one mega symbol called a Giantoonz. If two or more Giantoonz is part of a winning payline, your wins are doubled!

Final Verdict

With the mumbling and chirping that you hear throughout the game, added to the yellow one-eyed alien on the reels, it’s a struggle not to let your mind stray to the Minions movie franchise from time to time – but resist the urge, or you could miss a rare big win with this top slot

These potential ways to win speak to the game 96.51% RTP. Sure small wins are a dime a dozen, but the big ones take forever. It is not hard to go 50 or more spins, with 10x your bet being your highest payout.

It can take a long time to collect the wins needed to unlock Gargantoon, and even then, cracking the 75x-100x payout range is not a guarantee. You’ll be entertained with a flood of small victories and visually stimulated. If you’re in it for the rush of releasing Gargantoon and seeing if you’ll be the ones to divest him of his intergalactic fortunes, then this is for you!
