Reactoonz slot at Mr Green Casino

Reactoonz has been developed by one of the leading casino slot providers, Play’n GO. With impressive visuals and promising cascades, this game introduces you to the virtual realm of energized aliens, ready to take on your world. From wild symbols to generous bonus features, Reactoonz is designed for the enthusiastic player who wants to stretch the full scope of their gaming potential.

How to play Reactoonz

Reactoonz is a 7X7 (reel/rows) grid game with a progressive cluster system. At Mr Green online slots have varying paylines and maximum or minimum payouts. For Reactoonz, the maximum payout is 91.406 coins, which is very tempting. However, keep in mind that the game is highly volatile, so you may need to play for quite some time before achieving any high wins.
Since the game pays out clusters of winning symbols, there are no payline adjustments to make. You’ll only need to decide on the amount to wager per round, i.e., from € 0.20 to the highest, € 100.  Once you’re good to go, click on the green bottom at the bottom right of the screen to start your round. You can also select the AutoPlay option by clicking the yellow button to the right of the green button. The number of auto spins to select range from 10 to 100. The slot’s paytable gives you the value of the cluster payouts.

Reactoonz Symbols

Reactoonz features alien characters set in a futuristic virtual world that’s both fun and engaging to interact with. 4 higher-paying symbols (represented by two-eyed aliens) and 4 lower-paying aliens (represented by one-eyed aliens) transform this virtual and colourful environment into a winning opportunity for the players. The soothing background music blends well with the snoring Gargantoon and high-pitched sound effects from the alien creatures. All of this together creates an environment which is both unique and fascinating.

Reactoonz Wild Symbol

Quantum Leap, Giantoonz, and Gargantoon features all give wilds, which substitute for any of the other symbols. While most online slots have wilds that just appear on the reels, Reactoonz is different. Here, the Wilds don’t just appear; they are created! When you spin the reel, one symbol fluctuates. If a winning combination contains this symbol, 2 wild symbols are left behind once the cluster disappears.
Another way in which the wild symbols appear is when the Gargantoon feature is activated. We shall discuss this later on.

Reactoonz Bonus Features

Besides the wilds, Reactoonz comes with lots of bonus features and free spins which make the game even more exciting. These are:

Cascading and Cluster Pays

Instead of spinning reels with paylines, Reactoonz features cascading symbols. When 5 or more identical symbols appear horizontally or vertically (adjacent to or touching each other), you win. The group of symbols creating a winning are called clusters. The latter explodes, leaving spaces behind, which are then filled by more cascading symbols. This process continues for free as part of the game round, until there are no new winning clusters.

Quantum Leap Charge Meter

‘Quantum Leap Charge Meter’ is a feature located to the left of the reels. This meter is charged by 1 when the winning clusters appear within each game round of cascading symbols. Once this meter is fully charged, it will randomly add 1 of the 5 possible Quantum features to a queue, which will be triggered at the end of the round. Below is a summary of what the features offer:
Implosion: This feature transforms 3-6 symbols into wilds and destroys the adjacent symbols simultaneously.
Alteration: 1 Low-value symbol (one-eyed alien) is chosen to be replaced by another symbol. If there’s no low-value symbol, a high-value symbol will be chosen instead.
Demolition: With this feature, all instances of one-eyed aliens (low-value symbols) are destroyed.
Incision: A wild symbol is cut into the centre which then creates two intersecting diagonal lines of an identical symbol that runs the length of the grid.
Gargantoon: When all the five levels of the meter have been charged, the Gargantoon Feature is added to the queue. This feature randomly places a 3X3 sized wild symbol to the grid. Once the cascades are completed, the same symbol transforms into a 2X2 wild and ends as 9 (1X1) wild symbols.
If you don’t get a win, one of the Quantum features may still be trigged. The Gargantoon symbol can randomly appear on any losing round, depositing 4 to 8 wild symbols on the grid. This is called the instability feature. 


When a square-shaped pattern of 4 regular and identical symbols appear, it forms a ‘Giantoonz.’ This feature gives a 2X multiplier, which doubles the wins.
