Reactoonz

Reactoonz is a uniquely-designed casino game from Play’n GO that sees cute alien creatures on a 7x7 grid that invade the reels with a series of bonuses such as cascading symbols, wild substitutions and special Quantum features like transforming symbols or extra wilds. Available to play across desktop and mobile platforms at the many online casino sites that feature the Play’n GO range, like everything from this developer, the Reactoonz video casino game has fair gaming and high returns.

It’s also got the fun design touches that so many of their games feature, with lots of little details that players may miss the first time they launch the game, but they add to the overall effect. A blue background is filled with these critters, each of which is slightly animated, bobbing up and down a little, blinking, or looking around at the aliens next to them.

A couple of bits of extra-terrestrial machinery sit on either side of the reels, including what looks like a transporter device, while to the right side, a giant three-eyed, multi-horned beast sleeps peacefully, waiting to be awoken when bonus features are triggered.

Playing Reactoonz

To get these fun characters spinning down the reels, gamblers will need to stake a low limit of 0.20, and those on bigger budgets can raise this in increments to a maximum of 100.00, while free Reactoonz casino game are available for anyone who wants to get some practice spins in before playing for real.

Little one-eyed aliens return the smaller prizes, while higher value aliens each have 2 eyes and horns to make them stand out. Unlike normal casino games where players are hoping to get matching symbols across a payline, wins in Reactoonz come from any 5 or more matching symbols landing adjacent to each other in any pattern.

When this happens, the poor creatures that made up the win will explode, leaving an empty space into which symbols from above will drop into, This Cascading Reels system can lead to several wins in a row and with each, the transporter to the left of the reels starts to fill up. Once wins from 25 symbols have been had, whether from a single series of Cascades or separate spins, a green charge bar on the Quantum meter to the right is lit up.

Quantum Bonuses

A lit bar adds a random special feature to the reels, which could be the Alteration, where a lower value symbol is turned into a higher one, or the Implosion, which sees between 3 and 6 symbols turned into wilds, while any around them are blown up.

In the Demotion feature, all lower value symbols explode, leaving just the 4 high-paying ones, which should make it easier to get some bigger winnings, while the Incision feature sounds painful, but is merely wild symbols fanning outwards in diagonal lines from a central wild. This can create multiple winning groups of symbols, and of course, any that make up a win will disappear for a Cascading Reel award.

Energy Wilds and Gargantoon Wilds

A swirling blue and pink ball of energy is a wild symbol that will act as any other and can therefore connect more symbols together for higher payouts. If the Quantum meter is filled with 5 lit bars, the Gargantoon moves onto the reels as a giant 3x3 wild symbol. If a Cascade occurs, it will divide into a couple of 2x2 wilds and should a third Cascade be triggered, the Gargantoon then becomes 9 individual wilds on the grid. While players would be pretty unlucky not to get a win in this third Cascade, a random Quantum feature will be applied if they don’t, virtually guaranteeing a prize.

There’s also the chance for an Instability feature in any non-winning spin, where the friendly Gargantoon will drop any number from 4 to 8 extra wilds into the grid. Other wilds can appear in the Fluctuation feature, which sees a low-value alien singled out with each spin, and if it’s part of a winning group, 2 extra wilds appear.

Yet another potential bonus is the Giantoonz feature and this doubles the value of any coins won in a spin where matching symbols appear in a 2x2 block.

The Verdict

The Reactoonz casino game initially seems to be quite a complicated game, but each time a bonus is triggered, the name of the feature is announced on screen and once each has happened a few times, it becomes fairly easy to follow the action.

Frequent wins, although often at smaller values, occur in this fast-paced game that has a fun theme, high quality design and plenty of alien-based action to keep gamblers happy, and being mobile-optimised, they can play it across multiple devices.
