Reactoonz Online Slot Review

Have a close encounter with a bunch of aliens when you play the Reactoonz slots game. These cute critters appear over a huge 7x7 grid, and vanish when you land clusters of at least 5 of a kind. Cascades follow, potentially creating new winning clusters.

Other features of the Reactoonz online slot include wild symbols, win multipliers, and a huge Gargantoon wild symbol that helps to complete wins over the course of several spins. It’s the work of Play'n GO and like others in their range, it’s fully compatible with iOS, Android, and Windows mobiles, as well as PCs.

The Reactoonz slots game has a high volatility and average returns of 96.00%. With luck, the alien invaders will boost your bankroll by up to 457,000.00 at the highest stakes.

How to Play the Reactoonz Slots Game

There’s a cute cartoon style here, with a weird and wonderful selection of round, square, triangular, and glowing aliens on the grid. Lower paying symbol have a single eye, while the more valuable aliens have 2 each, and the giant Gargantoon is a 3-eyed beastie. He rests in a transporter beam to one side of the game, waiting to be zapped onto the grid, while a Quantum Leap meter is on the other side. Fill this with enough winning symbols to trigger bonus features.

You can play with a stake of 0.20 per spin, or by using a scrolling bar beneath the reels, raise your wager through multiple options to a maximum of 100.00 at the best Pennsylvania and the best New Jersey slots sites. It’s a generous range, and most players will find an ideal wager level here. Click the yellow arrow tab to set the reels spinning on their own, and the ‘I’ button on the other side opens the paytable, where you can review how much each cluster pays.

You need to land at least 5 examples of the same symbol, connected horizontally, vertically, or in blocks to win. The top alien returns 1200x your total wager if it lands in a cluster of 15 or more.

Reactoonz Slot Machine Bonus Features

There are no free spins rounds, or progressive jackpots in the Reactoonz slot, but that doesn’t mean its lacking in features. On the contrary, this game is packed with extras that can turn any spin into an exciting event.

For starters. It uses a cascading reels mechanism, where winning symbols vanish, and new ones drop down to fill the empty spaces. If this creates further clusters, the cascades repeat, and so on, until no new winning combinations are seen.

Winning symbols throughout a series of cascades will charge the Quantum Leap meter, and for each 25 symbols, a bonus feature gets placed in a queue. Any bonuses then play out at the end of the cascades. You could trigger any or all of the following –

The 3-eyed Gargantoon appears on the reels whenever the Quantum Leap meter fills right up during cascades. It’s a 3x3 wild which becomes two 2x2 wilds on the next spin, then 9 individual wilds on the following spin.

Any 2x2 cluster of matched symbols will transform into Giantoonz. These wild symbols double the value of any win they become part of. Other features include the Instability bonus, which places up to 8 wild symbols on the grid after a non-winning spin.

Our Reactoonz Slot Verdict

Although there’s no free spins feature from this game, you won’t have time to miss one, as the cascades, Quantum Leap bonuses, extra wilds, and giant alien creatures will be more than enough to hold your attention.

Reactoonz is a cheerful game with plenty of humouros creatures on the grid, and a fun soundtrack. Check it out in desktop or mobile versions at our recommended Pennsylvania slots sites and the top New Jersey slots sites, with the biggest bonus offers featured here.


The Reactoonz slot machine is a cluster pays game. You win a prize whenever groups of 5 or more matched symbols land on the 7x7 grid. The symbols can be connected in horizontal rows, vertically, in blocks, or a combination of these. Bigger clusters pay higher prizes, and there are numerous bonus features to help create wins.

Yes, it is. High volatility games such as the Reactoonz slot pay out prizes less often than lower variance games, but overall, wins tend to be higher in value. It’s always important to pick a wager level that can stand a few losing spins in a row, even if the eventual payouts will make up for it.

You can play the Reactoonz slot machine for between 0.20 and 100.00 per spin. It’s easy to select a suitable wager from a bar beneath the reels, and there are lots of options to suit almost any bankroll.

If you manage to fill a meter with enough winning symbols during a series of cascades, a Gargantoon symbol is unleashed. This 3x3-size, 3-eyed alien is a wild symbol which will create multiple winning clusters at once to trigger cascades. It reduces in size over the next 2 spins.

Unlike most slot machines, the Reactoonz slot doesn’t have a free spins bonus feature. But there are lots of other treats instead, such as random wilds on losing spins, wild symbols crisscrossing the grid, symbol destruction for bigger cascades, or symbol transformations for greater cluster sizes.

There’s no download needed to play the Reactoonz online slot. You can access it on a PC or mobile via a browser, along with the many other games found at the top casinos.

It’s part of a small series. The Reactoonz slot has spawned a sequel, imaginatively named Reactoonz 2. In this game, you charge a meter to unleash bigger and bigger wild symbols and greater multipliers onto the grid. Many other features are carried across from the original slot.

The cute alien symbols give the Reactoonz slot instant appeal, while the exciting features keep players coming back to the game again and again. It’s available at some of the top online casinos, so lots of players have access to the game at our favorite sites.

The Reactoonz online slots game comes from Play’n GO. It’s part of a successful range of desktop and mobile games that encompasses huge hits such as Book of Dead, House of Doom, Rise of Olympus, and Fire Toad.

Play’n GO launched the Reactoonz slot machine on 15th October 2018.
