Reactoonz slot with offers for 100 free spins


Reactoonz is an online video slot from Play’nGo that builds on the Energoonz slot , one of the most popular titles from this Swedish software provider. 

Play’n GO makes increasingly innovative slots, as we saw with the brilliant Moon Princess and the Viking Runecraft popular with high rollers . These are slots with falling symbols, which can cause chain reactions and thus give large payouts. A very successful format, which is embraced by many players.

Reactoonz also fits in this list. The game is hectic, fast and even confusing at first. A lot is happening and especially when several combinations fall one after the other, it can all get dizzy. But that’s just a matter of playing around and letting it work on you.

At a certain point you get the mechanism and you soon realize how great fun Reactoonz is.

How does the Reactoonz slot work?

The game is played on a matrix of 7 x 7 symbols, filled with all kinds of colorful space creatures. There are no fixed paylines, but payouts are created by clusters of the same symbols. Winning combinations are created with 5 or more of the same symbols in a cluster. The more symbols in a cluster, the higher the payout. If there is a 2 x 2 symbol in a winning combination, the payout is doubled.

Winning combinations disappear and make way for new symbols, causing a chain reaction.

You pay a fixed amount per spin, from 0.20 euros to a maximum of 100 euros.

Special symbols give extra wilds in Reactoonz

Each spin 1 symbol is designated that acts as a special symbol. If a winning combination is made with this symbol, it leaves 2 wilds, for more chance of new winning combinations.

The Gargantoon: extra boosters

On the right side of the screen you see a white monster with 3 eyes. This is your friend the Gargantoon. When you make winning combinations, the meter fills up. For every full meter 1 of the 4 boosters is activated. These boosters can help you enormously to make even more winning combinations, even if one is a lot more powerful than the other.


 This is the best booster: 3 to 6 symbols are turned into wilds and all surrounding symbols are destroyed.


1 random symbol changes into another symbol – this is often of little use to you.


 all low symbols are removed.


 a wild symbol is placed in the middle, and two crossed diagonal rows are filled with the same symbols. Very powerful, especially when the rows are filled with wilds.

When 5 meters are filled, it is completely party time. Now the super powerful Gargantoon Feature is added to the queue. This Gargantoon Feature provides a lot of extra wilds on the screen. First there is a 3 x 3 wild symbol on the screen, then a 2 x 2 wild and then nine loose wilds. It seems as if the complete hysteria has erupted, often resulting in large payouts.

The Gargantoon can also conjure up extra wilds on the screen after a non-winning spin: between 4 and 8 wilds.

Reactoonz payout, RTP and volatility

Reactoonz has a is 96.51% is fine.

Reactoonz has a very high volatility and Play’nGo rates it 10 out of 10 in its volatility scale. Especially if you manage to get a nice chain reaction and the Gargantoon feature, you can easily take winnings of more than 1,000 x your bet. We have managed to do this several times, which has earned Reactoonz a number of entries on our biggest online slots wins page.

But be warned: Reactoonz can be very erratic and sometimes barely give anything for a long time.

Slot Review Conclusion on Reactoonz

At first we had absolutely nothing with this new slot from Play’n GO. Too busy, too complicated and our money used up way too quickly. Fortunately we persisted for a while.

This slot can pay out very nicely and if you get the Gargantoon Feature, then it is just a big party on your screen. And as soon as you get more than 1,500 x your bet in a spin within a few seconds, Reactoonz is suddenly a really, really fun slot. And if you succeed again 10 spins later with a payout of 365x the bet, then you are a fan for life.
