About Reactoonz Slot

Reactoonz slot is a Play’n GO developed slot in which identical alien symbols form a cluster and land winning combinations. This 7x7 grid has no paylines, instead of staking a bet on an individual line, players can wager anywhere between 20p, to a £100 on the entire set of reels, making room for outlandish 15 of a kind wins! The winning combinations are clustered together whenever a group of five or more mutant symbols land together. In the Reactoonz slot, the extra terrestrial symbols can infiltrate the reels and group horizontally, vertically or in any direction on the grid, offering Legs Eleven players a swarm of winning potential! As players land winning combinations during a game round, they will crank up the voltage and charge the Quantum Leap meter sitting at the side of the reels. Once this meter is fully charged, players can trigger one of four bonus features. Reactoonz may provide Legs Eleven players with a close encounter of winnings!

How To Play Reactoonz Slot


Select any of the set bet values located at the bottom of the reels in purple buttons. To either increase or decrease these amounts, toggle between the (-) and (+) arrows located at either side. The minimum bet value available in this online casino game is 20p and the maximum is set at £100.


Spin up a vortex in the Reactoonz slot by hitting the spin button. This will set the martians in motion and symbols will drop onto the reels for one consecutive round. If players land a winning combination, these symbols will disappear from the reels and more extra terrestrial ‘toonz will drop onto the reels to give players a shot at landing bigger winning combinations.

Auto Play

Located next to the spin button, in a smaller yellow version, is the autoplay button. Players can meet their match with the Reactoonz martians without lifting a single finger. Select the autoplay feature and players can determine how many spins to play out automatically, along with triggers that can stop the feature if players win/lose over a set amount.

Fast Play

Legs Eleven players are free to take a spin of the Reactoonz slot faster than the speed of light with the Fast Play feature. This can be switched on and off by opening up the menu table, which is in a three bar symbol form located in the bottom left corner. Here in this menu, Legs Eleven players are also free to alter other settings, such as sound, auto bet and more.

Reactoonz Slot Features

Quantum Leap

If players are lucky enough to land winning combinations, they will increase the Quantum Leap meter that is located at the right of the reels, with a fellow cosmic companion. When the meter is charged, one of the quantum features will be added to the queue randomly to help blast off players winning potential.

Implosion Feature

Anywhere between 3 to 6 of the mutant symbols are transformed into wilds to increase players’ winning opportunities! The adjacent symbols will also be removed from the reels, leaving space for new winning combinations.

Alteration Feature

Reactoonz slot’s parallel universe alters one of the lower paying symbols and transforms into a higher paying symbol if you trigger the alteration feature. If there’s no lower paying symbols on the grid, a high value alien will replace the symbols.

Demotion Feature

In the demotion feature, all lower value symbols are blasted off the reels to make space for new species of symbols.

Incision Feature

If players are awarded the Incision feature, they can watch on as a wild cuts through the grid and creates two lines that will form a randomly chosen symbol, .

Gargantoon Feature

Keep an eye out for the mega Gargantoon mutant! If players manage to fill the 5 charge meters, this feature will be added to the queue. The Gargantoon will begin by adding an oversized 3x3 wild to the grid, to help players land winnings. This symbol then transforms into two 2x2 symbols, then nine 1x1 symbols. Each time the Gargantoon shifts and transforms with every win, new symbols cascade down from the top of the reels. Better yet, if players are unsuccessful and land a non-winning spin, there’s a chance that they may meet the Gargantoon at random, where the mutant will drop 4 to 8 wild symbols on the grid to blast winning opportunities sky high!

Giantoonz Feature

If players manage to land 4 identical symbols adjacent to one and other in a square formation, these will shapeshift and create a Giantoonz mutant! Along with that, players wins will automatically be doubled.

Fluctuation Feature

Fluctuate your winning potential with the fluctuation feature. 1 random lower value symbol will fluctuate on each spin and if it’s part of a winning combination, it will leave behind two wild symbols on the reels as it disappears.
