Play Reactoonz slot at Mr Green Ireland

Reactoonz is an out-of-this-world slot from one of the top providers, Play'n Go, that has seven reels and seven columns on the screen. This grid is filled with a selection of weird and wonderful creatures from outer space. It pays out on clusters of matching symbols and has an enjoyable cascading feature that sees winning combinations zapped and replaced with new symbols.

How to Start Exploring the Reactoonz World

The top prize on this fast-moving slot is 91,406 coins. As Reactoonz is a high volatility game, the prizes are bigger than lower volatility slots, but the wins are potentially less frequent overall.

Getting started is simple, as there are no paylines for you to select before you play. Instead, you just need to choose the size of bet that you are comfortable with, from the selection under the reels, with quite a few other figures in the middle of these levels too. You then hit the Spin button to play the first game.

Any wins or features that you collect will be automatically credited to you once the spin has come to an end. All the wins are paid out according to the Reactoonz paytable, with a minimum of five matching images needed for a payout.

The biggest symbol wins are paid out when you get 15 or more of the same image in a huge cluster. This can go up to 1,200x your wager on the top symbol, which is a purple visitor from an unknown galaxy. If you want to play more games more quickly, the autoplay function lets you choose 10, 20, 50, 75 or 100 automatic spins with a series of options to stop the games when your wins reach a certain level or your overall balance changes by a certain amount.

The Key Symbols

You will find that the colourful aliens on the symbols are divided into two different types of creature, with four different kinds of each in the paytable. Those with two eyes are worth more to you than the others with just one eye. The developers at Play'n GO have gone for an amusing, cartoon feel to the graphics, which is also reflected in the entertaining sound effects that let you hear some of the aliens’ weird voices.

The wild can help complete a paying combo by standing in for any of the other aliens. The wilds are created when a winning cluster includes one of the fluctuating symbols, as this combination will leave behind a couple of wilds when it is removed. You could also see the wild symbol if you trigger the exciting Gargantoon feature, which we will look at in the following section.

Reactoonz slot features to be aware of

This extra-terrestrial adventure is made more interesting thanks to the galaxy of unusual features that you can trigger as you play it.

Cascading Wins and Winning Clusters

The first thing you will notice is that the reels don’t spin like they do in the majority of slots. On Reactoonz, the new symbols drop down from outer space directly onto the 7x7 grid. You will get a payout for five or more identical aliens landing in a cluster where they touch either horizontally or vertically. 

The action continues once you have a winning cluster, as it will be removed from the reels, with new icons cascading down from above to replace them. This process will continue until no more winning combinations can be made.

The Quantum Leap Meter

If you look to the side of the screen, you will see the impressively named Quantum Leap Charge Meter. This is a type of other-worldly machine that is charged up with every win that you get. Once it is fully topped up and ready to unleash its power, you will get one of the following features.

Alteration: This is where one of the single-eyed creatures is chosen at random. All occurrences of this alien will be removed, and another icon put in its place.
Demolition: This powerful feature blasts away all images of one-eyed creatures, giving you the chance of bigger wins.
Implosion: Between three and six aliens become wild, and the symbols next to them are zapped away.
Incision: You get a wild symbol slap bang in the middle of the grid. A couple of diagonal lines of matching icons are added to the screen as well.
Giantoonz: If you get four of the same aliens together in a square, they will merge to create a symbol known as a Giantoonz. Any wins that they are part of will contain a 2x multiplier on them.
Gargantoon: The mighty Gargantoon feature sends a giant 3x3 wild onto the reels. This outlandish creature then divides into smaller symbols and moves with each subsequent cascade.

You might also see the Gargantoon pop up randomly to give you wild symbols if you have a non-winning spin. You can get up to eight wilds in this way, and a second bite at getting a winning cluster.
