Reactoonz review

Watch these little aliens form clusters and pop out of existence as you land on winning combinations and activate the cascading game mechanic.

If this has already piqued your curiosity, read our full review below to learn about the slot’s unique features or try it out with an online casino where you can already play it for free or real money.

Reactoonz slot features

Reactoons slot is played on a 7×7 grid with a cascading mechanism, where winning combinations are destroyed and replaced by the other symbols on top of them.

8 quirky alien symbols populate the grid, with the highest paying one being the pink alien, which pays 750x your stake for a cluster of 15.

In order to win, you need at least 5 symbols to form a connected cluster, which means that these symbols have to occur vertically or horizontally next to each other.

When 4 matching symbols land next to each other to form a square, these will transform into one big Giantoonz symbol, which is a multiplier that will double the win of a winning combination.

The slot also contains a fluctuating symbol, which is selected from one of the one-eyed alien symbols during each spin; this leaves two wild symbols behind it if it becomes part of a winning combo.

After every win, you’ll see that the meters to the side of the grid charge up, with the possibility of triggering one of Reactoonz slot’s 5 Quantum features.

Reactoonz slot Quantum features

The aim of this slot is to activate one of the quantum features, which results in symbols being transformed or destroyed in your favour. These features include:

The Implosion feature – in this case, 3 to 6 symbols become wilds, and those symbols adjacent to them are destroyed.

The Alteration feature – 1 low-paying symbol is picked out at random, and all instances of that symbol transform into another symbol.

The Demolition feature – Activating this feature will result in all low-paying symbols being destroyed.

The Incision feature – a wild in the centre of the grid produces 2 intersecting diagonal lines across the grid.

Reactoonz slot Gargantoon feature and free spins

If you do manage to charge all 5 meters, this will unleash the slot’s Gargantoon feature; at this point, the monstrous Gargantoon that has been locked up on the side is released onto the grid and randomly adds a 3×3 wild. With every cascade, it splits to become two 2x-2 wilds, and into nine 1×1 wilds following the next cascade. What’s more, this Gargantoon can add 4 to 8 wild symbols to the reels following a non-winning spin! 

Reactoonz slot has no free spins feature, but instead players are rewarded by means of a combination of quantum features, wilds and multipliers.

Reactoonz slot bonus

Apart from the bonus features within the game itself, playing Reactoonz at certain UK casino sites will also come with a generous casino bonus which may include bonus money as well as free spins which will give players the opportunity of trying the game for free!

Play Reactoonz with one of the trusted online casinos we recommend to make the best of their welcome or special offers!

Reactoonz slot minimum and maximum bets, volatility and jackpot

You may play Reactoonz slot with a bet size that ranges between 20p to £100.

The game has a decent RTP of 96.51%, but we do caution against getting too carried away by the adorable aliens’ smiles!

It’s worth keeping in mind that the slot is of high volatility and has a rather low hit frequency, which means that you might find yourself having to bet significant amounts before landing a big win.

Payouts however are quite high, with maximum wins of up to 4,570x your original bet amount!

Reactoonz slot graphics and sound

Reactoonz is no exception to the rule when it comes to its design; like all Play’n Go slots, its graphics are of very high quality and the combination of colours is very visually appealing.

The sounds help create an interstellar atmosphere, where things are rather quiet at the beginning, as sharp music beats are interrupted by loud bursts during the explosions and a reverberating noise in the background.

The music then picks up once you start triggering the quantum features, and becomes jollier to parallel the excitement that’s about to come!

Reactoonz slot – our Conclusion

Play’n Go’s recent release is an original slot with an impeccable design and an interesting futuristic theme.

We liked the mix of bonus features, and the intensifying excitement once the quantum features are triggered, which is reflected really well by the background music.

A slightly better hit frequency would have been welcome, but ultimately we believe that Reactoonz is just what high volatility slots are all about; there are some big wins to be had, but it’s recommended to play set your limits!
