Reactoonz: Casumo’s Most Popular Slots Series

In Casumo’s Most Popular Slots Series we’re highlighting one amazingly popular slot at a time. It could be a golden oldie or a brand new-ie; as long as the game has rightfully deserved its moment to shine, we’ll be there to put the spotlight on it. In the fifth game highlight of our Most Popular Slots Series we’d like to talk about a parallel universe charged with stellar power (and lots of cute-looking aliens): Reactoonz! 

Beep…Beep….Bop, we come in peace!

In Reactoonz, the hit 2017 slot game by Play’N GO, aliens drop from space on a 7×7 game grid. It’s a playful parallel universe charged with stellar power and potential prizes, of course. Reactoonz features random Wilds, a multiplier bonus feature and Quantum Leap Bonus features. What’s the success story behind this energetic extraterrestrial slot, you ask? We’ll tell you all about it further below.

What Reactoonz is all about

Reactoonz is a cascading-style slot with a 7×7 grid. To win, you must land a cluster of 5 or more similar symbols in any pattern. You could win up to 4,570x your bet on every cascade. With each win, you charge up a special meter to randomly trigger the Quantum Leap Bonus features. These give you symbol transformations, destructions and a Gargantoon which adds Wilds on the reels. 

Now let’s have a closer look at some of the game features, shall we! 


Highly animated aliens drop from outer space and land to occupy the 7×7 game grid. Each cluster of 5 or more aliens of the same race will land you a win: The larger your cluster, the higher your win potential!

Quantum Leap Bonus

Each winning cluster transfers energy to the power-hungry Gargantoon who waits on his base, planning his invasion. When fully charged, Gargantoon grows and makes a Quantum Leap onto the middle of the game grid, where he goes completely wild and releases a chain reaction of up to five special features that might lead to more winning combinations.


Try to make contact with the oversized aliens! They could multiply your wins when they become part of a winning cluster.

Wild Symbols

The flux capacitors essentially serve as random Wilds and could help increase your win potential.

Multiple Wins

Aliens in winning clusters are instantly teleported away to be replaced by new space invaders from above, which potentially gives you multiple chances to win in the same round.
