Reactoonz 2 Slot Review

Released October 2020

The Reactoonz 2 slot can be found at casinos offering Play ‘n Go software. Play ‘n Go are a growing providers in the industry and have a rapidly expanding portfolio of both slots games and clients. They do offer a full casino platform, but primarily seem to be used as a bolt on package for extra slots games. Play ‘n Go do publish the Return to Player (RTP)/House Edge information for their slots games within the game help files. As such, we know that the house edge for Reactoonz is 3.8%.

The Reactoonz 2 game does not use the standard slots game format. There are no traditional reels or paylines. Instead there is a 7x7 grid of symbols that generates a win when clusters of aliens from the same alien race are formed. Clusters are made up of 5 or more matching aliens that are horizontally or vertically adjacent. When you align a cluster, the aliens that form it will disappear from the screen, leaving space for more symbols to drop down and provide an additional chance to form a cluster. The bigger the cluster, the bigger the payout.

Special Symbols

There are a few Wild symbols. Instead of describing them in this section they make more sense when added to the features section.

Bonus Features:

Fluctometer – The Fluctometer sits on the top right-hand side of the screen and will display one of the Reactoonz symbols on each of your spins. If you manage to land a cluster of those symbols then an Electric Wild symbol will appear on one of the symbol spaces vacated by a disappearing symbol cluster. Once the Fluctometer is full, up to 3 symbols can land in the spaces left behind by symbols from the Fluctometer.

Quantumeter – The Quantumeter is found in the bottom right-hand side of the screen. Every time an Electric Wild substitutes for a standard symbol you will fill part of the meter. The Quantumeter has 4 charge levels and holds up to 135 charges. Level 1 requires 55 charges, level 2 requires 85, level 3 requires 110 and level 4 requires 135. Level 3 is the fully charged state of Quantumeter and level 4 is its overcharged state. Quantumeter continues to charge after releasing an Energoon, but releasing Gargatoon disables it.

If the Quantumeter fails to reach level 3, it unleashes Energoon Wilds to the grid. Level 2 unleashes a single 2x2 Energoon Wild, at a cost of 30 charges. Level 1 unleashes 4 symbols of 1x1 Energoon Wilds, at a cost of 55 charges.

If the Quantumeter is at level 3 or above, it unleashes Gargantoon Wilds to the grid. Level 4 adds a x2 multiplier for all wins including Gargantoon Wilds, but only a single x2 multiplier is used for each winning cluster. Level 3 unleashes a single 3x3 Gargantoon Wild. After 3x3 Gargantoon triggers a cascade, it is replaced by two 2x2 Gargantoon Wilds. After 2x2 Gargantoon triggers a cascade, it is replaced by nine 1x1 Gargantoon Wilds.

Wild Pair Explosion – This feature will activate if there are 2 or more Electric Wilds left on the grid, after all wins have been established. 2 Electric Wilds are randomly selected, always preferring those that are horizontally or vertically adjacent. A pair of adjacent Electric Wilds will remove all other symbols, except for other Wilds.

Uncharged Wilds – These can land on any spin. They do nothing unless they sit adjacent to winning symbols, at which point they will transform into Electric Wild symbols.


Reactoon 2 is every bit as mind-blowing as the original slot. Reactoonz was one of the slots helped put Play ‘n’ Go on the map and this reanimation of that slot is a timely reminder of just how utterly confusing and enthralling the original was. Despite being a different slot, Reactoonz 2 looks very much like the original. The features are however different, relying on a series of reactions that are slightly different. One thing that is worth noting is that you can trigger many, and I mean many different reactions without winning a huge amount of cash. In other words be careful to check what you are winning and don’t let all those bells and whistles suck you in. Despite that warning I would recommend this slot.
