Reactoonz Explained

Reactoonz is a cluster pays slot that takes place on a 7x7 grid. This means that payouts are won by landing groups (or clusters) of matching symbols horizontally or vertically on the grid. The slot also uses cascading reels. When winning formation lands, the symbols in it will disintegrate and be replaced by more falling from above. This can lead to multiple wins from a single spin. Players will also benefit from unique bonus features, including the quantum leap, Giantoonz and fluctuation.

Reactoonz is an entertaining slot set in the Gargantoon’s space laboratory. The graphics are well designed with colourful fun characters. The cartoon and futuristic setting have great sound effects and a bouncy background theme tune.

There are eight alien cartoon character symbols. Of these characters, four are high value and are represented by two eyed aliens of different colours. The four lower value alien characters have only one eye and are also different colours. The Gargantoon is a 3x3 sized monster alien symbol with three eyes. Wild symbols are circular multi-coloured symbols that swirl and sparkle.

Bonus Features

Reactoonz is packed with bonus features that can contribute to big wins. Bonus features include Giantoonz, fluctuation and instability. The quantum leap feature can host up to four different reactions plus the ultimate involvement of the Gargantoon.

The Giantoonz feature will double your win multiple when any four matching symbols land in the cascade and form a 2x2 ‘Giantoonz’. The Giantoonz must then form a combination with a minimum one extra matching symbol to collect a win.

Before each spin, a set of one randomly selected one-eyed alien symbols are glowing on the grid. This means that alien is marked as a fluctuating symbol. When the fluctuating alien forms part of a winning combination on the next spin, it will leave two wild symbols behind.

Instability is a bonus feature delivered randomly by the Gargantoon. The feature provides anything from four up to a maximum of eight wilds that will be dropped on the grid to improve the chances of a win.

The Quantum Leap is the slot’s main bonus feature. Quantum Leap offers five different quantum features. They are Implosion, Demolition, Incision, Alteration and finally the Gargantoon. To utilise these features, you need to start charging the quantum leap. Upon winning one or more combinations that remove 25 symbols, the Reactoonz quantum leap machine will have charged sufficiently to generate a bonus feature. If you continue with the run of combinations then the other Reactoonz quantum features can be charged.

The bonus features have different effects. Alteration randomly selects one of the one eye alien symbols and all its matching symbols will be turned into a different symbol. Demolition will destroy all matching symbols and one eye aliens from the grid allowing the cascade to replenish the grid. Implosion will create anything from three to six wilds that will then destroy each adjacent symbol, allowing for the cascade to replenish the grid. Incision creates a wild in the centre of the grid, where two diagonal lines are formed from each corner of the grid. The diagonal lines will be represented by a randomly selected alien of the same type. Finally, if the winning streak is maintained and the Quantum Leap is fully charged, the Gargantoon will form a 3x3 monster wild symbol on the grid. In the following cascade the Gargantoon will divide into two 2x2 Gargantoon wild symbols. In the final bonus cascade of the Gargantoon feature, it divides into nine individual wild symbols.


Reactoonz slot is a high volatility slot and it has an RTP of 96.00%, which is average for online slots. Low volatility slots pay out small amounts regularly, whereas high volatility slots pay out large amounts less frequently. As such, when playing this game, players can expect to hit fairly large wins.

There is a large number of standard payouts available due to the number of combination factors. In brief, the largest payouts occur for combination of 10+ to 15+ aliens. The multiplier range for the highest value aliens is between 20x and 750x, for combinations of 10 to 15. For the lowest value alien the range is 0,80x to 3x for the same combination size.

How to Play

Reactoonz is an easy to play slot. Before starting the cascade, all the player needs to do is set their total bet per spin using the control button beneath the reels. All the player then needs to do is click on the spin button to start the cascade.

There is also an auto play function enabling you to select up to 100 automatic spins. The automatic feature can be set to stop if certain conditions are met, for example, if a certain amount is won or lost.
