How to play Reactoonz 2 mobile slot

The aliens are back, and this time they are bigger than ever as you get huge wilds after a cascade of wins in this Reactoonz 2 slot.

Technically this is the third in a long list of grid games. The Energoonz slot started the whole trend, and then Play’n GO launched the Reactoonz slot to make it bigger and better.

This means that Reactoonz 2 mobile slot has a lot to live up to, and for the most part, it does. The theme is similar – you have 7 by 7 grid of colourful aliens, with single-eyed aliens worth less than double-eyed aliens.

Every win will see the symbols explode and more symbols tumble from above, giving you cascades of wins and mini-spins. Better yet, all the symbols pay when 5 or more clusters of horizontal or vertical symbols pay.

Fill the fluctometer and quantumeter

There are no free spins in this Reactoonz 2 slot. But don’t worry, you get plenty of little wins to see you through because you need the avalanche of wins to fill the meters.

And yes, symbol wins of clusters of 5 or 6 will rarely do more than cover your bet (at the very best), but what you are looking for is a win using specific aliens.

Before every spin, the slots will choose one alien in the Fluctometer – the more wins you get using the Fluctometer, the more wilds you’ll find on the screen. The more wilds you get as part of a win, the quicker you’ll fill up the Quantumeter.

This bonus feature has four levels and is how you get the game’s biggest wins, mainly because you’ll get either 1×1, 2×2, or 3×3 mega wilds added to the screen. If you get to level four of the Quantumeter, you’ll have quickly reached a minimum of 10 wins, lots of cascades, and multiple 3×3 wilds with 2x multipliers.

It makes your heart race as you watch it happen.

Doesn’t this sound like a lot of hard work?

It does, but on the bright side, this is a little less volatile than the original Reactoonz game and has a decent top win of 5083x your total bet. So yes, you get bigger possible wins and more wins in general.

Sometimes, you can feel frustrated as you don’t quite know how many charges are left, why you are getting wilds, and how the game decides to give you mega wilds or not.

But you don’t have to be able to follow how slot machines work to enjoy everything they have to offer, and we’d argue that it doesn’t matter how you get the wilds. Because when they pop onto your screen, they sizzle, remove symbols, and create an avalanche of wins.

Bonus Features

Cascading Wins: On every win, the symbols explode and more will come tumbling down from below, giving you a second chance at a win.

Cluster Pays: When 5 or more symbols touch either horizontally or vertically you get a win on this Reactoonz 2 slot game.

Fluctometer: Randomly one symbol will be chosen in each round. If you get a winning cluster with that symbol, you'll get a single electric wild symbol in the spot of the winning symbols. If you get 11 symbols win, you'll get 1, 2 or 3 electric wilds randomly over the screen.

Quantumeter: All non-wild, one-eyed and two-eyed symbols removed by an electric wild or wild paid explosion will add to the charges in the Quantumeter. This has 4 charge levels and requires 135 charges.

  • Level 1: 55 charges - 4 1x1 Energoon wild to the grid
  • Level 2: 85 charges - 1 2x2 Energoon wild
  • Level 3 (charged): 110 charges - 3x3 Gargantoon wilds added to the reels
  • Level 4 (over-charged): 135 charges - 3x3 Gargantoon wilds with 2x multiplier added to the reels

After a Gargantoon explodes in a cluster, it triggers a cascade and is replaced by two 2x2 Gargantoon wilds. after a 2x2 Gargantoon cascade, it is replaced by 1x1 Gargantoon wild.

Wild Pair Explosion: This feature is activated when there are 2 or more electric wilds remaining on the grid. When adjacent vertically or horizontally, it will remove all symbols between them except wilds. If they are not-adjacent, it will remove any one-eyed and two e-eyed symbols between the pair of wild.s

Uncharged Wild: These can cascade onto the grid anytime. These do not take part in any wins but can be charged by adjacent winning clusters or wild pair explosion. Once charged, they become electric wilds.


  • Lots of bonus features
  • Frequent wins
  • Above average RTP at 96.2%
  • 5083x stake max win


  • Game mechanics too complicated for some

Reactoonz 2 Review Conclusion

The Reactoonz 2 slot is a strange machine, that will either have you running back again and again, or wonder why you should ever open up another online grid slot again.

Mostly because whilst it has a lot of features, it's a little complicated, and you never quite know when or how the feature will hit, giving it a chaotic feel you can either love or hate.

But the good news is that you can win up to 5,083 times your total bet thanks to an avalanche of wins and a whole load of cluster pays. Is energetic, it's fun, and it's worth trying out if you love other Play'n GO mobile slots.
