Reactoonz Slot Machine - Introduction

Reactoonz is an online video slot created by Play'n GO, a well-known name in the online casino games industry. Reactoonz slot is based on a unique giant grid (7x7). The minimum bet is €0.20, and the max bet is €100. You strike wins when you form clusters of similar symbols.

The slot has exciting bonus features, including vortex wild, fluctuation feature, instability feature, cascading game engine, and symbol removals.

This slot has a charming and friendly design. The colors are dynamic, and the other elements are also very quirky. It's fun to play with the match-5 format. 

This is one of the best-performing video slots by Play'n GO. The studio has done a great job designing the game. Players from all over the world love it and play it for hours.

Reactoonz slot has become so popular that the developer has also launched a sequel - The Reactoonz 2. The sequel has a lot of extra bonuses and features similar to this first release.


Theme & Design of Reactoonz Slot Game

Design & Theme

Reactoonz has a cute and quirky alien theme. Space invaders or aliens in different colors and shapes and other sci-fi elements exist. The elements and the aliens are amusing looking and cute. 

You'll see spaceships and aliens and a Gargantoon feature, and the Gargantoon is sleeping. But it will wake you up and give you prizes when you hit jackpots. The visuals and audio of the game are perfectly synced. All players would love this fantastic theme, and new players will easily be comfortable with the Reactoonz slot. We like grid-based releases like this that are similar to the ever-popular Sweet Bonanza Slot.


The symbols of Reactoonz also have a unique feature. The Symbols are active elements. They peek at their symbol companions, making the whole array dynamic and energizing. Some of them only have single eyes, though. And if you take too long to spin the slot, they even start chatting with each other. This is a fantastic feature of Reactoonz.

RTP Percentage and Volatility of the Reactoonz

The Return To Player percentage of Reactoonz is 96.55%, which is more than generous. The average RTP in online slots is around 96.00% to 96.50%; thus, the RTP of Reactoonz from Play N Go is higher than the Industry Standard.

An RTP of 96.55% means that when a player wagers 100 Euros in the game, he gets back around 96.55 Euros on average. This is not a guarantee of the return; the amount you get back might be higher or lower, depending on your luck. Thus, the house gets the edge of 3.45%.

The volatility of Reactoonz is high. It means that the number of big wins hit is lower than the average, but they are very generous when they do. The player will surely strike several smaller winning combos and prizes, but as mentioned, the chance of getting big prizes is fairly low. Due to this, this game is more suitable for players with experience in online casino games.

This Reactoonz slot has superb Quantum Features, which keep paying out more payout as we progress in the game, so all we need is just patience.


Maximum Win in Reactoonz

As the Reactoonz slot has a rating of highly volatile, it is not difficult to gather excellent fortune in the base game itself. But you can also trigger several bonus features in the game. The cascading reels and win option is probably the best thing in the game. This cascading game engine eliminates the matching symbols in the game and allows the symbols above them to fill their vacant spaces. Which then can trigger another win based on those new symbols. This chain win will keep triggering until there are no more winning combinations left. 

But the most sought-after feature of the game is the Gargantoon feature, which activates when you fill all 5 Reactoonz Quantum Leap Meters at one go, and it's the best chance to win the max win, which is a humongous 4,750x of your bet.

Being a cascading win game, Reactoonz has no fixed paylines. You can win in any number of symbols that are unpredictable. A winning cluster is formed when you form winning combinations of five or more similar symbols together in one spin. The single-eyed symbols are comparatively less playing than the two-eyed ones, giving a significant amount. The most lucrative symbols would be the two-eyed pink aliens, which can pay a gigantic 1200x payout (When you form a cluster of 15 or more similar symbols).


How to strike a Big Win in the Reactoonz Slot Machine

How to Win & Winning Combinations

Reactoonz uses the cluster mechanism to determine the wins. It means that when five or more similar symbols appear on the grid, they chain together, creating winning clusters. And the position of the individual symbols is essential, as the symbols need to be adjacent to each other if they are to be chained for wins. The adjacent symbols can appear either in the reels or in the rows. The diagonal symbols are not considered adjacent in the Reactoonz slot. 

When you successfully land similar symbols together, they chain and are removed from the game. Then their empty places are filled with the symbols above. This is the cascading win feature of Reactoonz. This bonus feature is known by different names in the online casino world. It is also called Avalanche Reels, Tumbling Reels, or just plain Reactions.

Wild Symbols

A whirl of yellow light denotes the wild symbol in the game. This symbol does not land on the grid on its own but needs to be generated by the player. When you spin the slot, you will notice that a random symbol in the game starts showing a glow of light. If you successfully land a combination with this glowing symbols form, it will give you two wild symbols in the next spin.

The great Gargantoon feature will generate the wild symbols randomly by simply blasting between 4 and 8 of them onto the reels at random.

Bonus Features in Reactoonz

In the Reactoonz game, once you collect 25 symbols in the meter, the energy stored in those symbols is transferred to the Quantum Leap Meter. This is placed on the other side of the grid, holding the reels.

There are four different Quantum Features:

1. The Implosion feature - This will transform the symbols in the game into wild symbols. Anywhere between three and six symbols can be converted into wilds. 

2. The Alteration feature - When triggered, the game automatically selects one of the low-value symbols. It will transform it into a different symbol, making it easier for the player to land a better winning combination.

3. The Demolition feature - When It is triggered, it will clear all the one-eyed or low-value symbols from the game, including the matching symbols.

4. The Incision feature will put a Wild symbol in the center of the grid. And it also places matching symbols across the diagonal lines. Thus, it potentially creates a winning combo.

The Gargantoon Feature

The Gargantoon feature is the most attractive bonus feature of the Reactoonz slot. So naturally, all players would want this Quantum feature Bonus. But the twist is that it is only activated once all other four Quantum feature bonuses have been completed. You must collect 25 more symbols in the Reactoonz Quantum Leap Meter to trigger this.

It will be worth the wait if you manage to spin the Gargantoon. First, it will leap onto the reels and take a space of 3x3. Second, it will act as a wild symbol and thus can result in some heavy wins. But the fun doesn't end here - it will then further divide into two 2x2 wilds, again resulting in some great winnings. And then again, when a win is struck, the Gargantoon will finally transform into nine small Gargantoon Wilds. They will take single spaces and give the player another opportunity to strike unique winning combinations.

The Instability Bonus 

This is a special bonus to spice up your game when it is going plain. When the player spins a non-winning spin, the Gargantoon will randomly throw wild symbols onto the reels. Thus, four to eight wild symbols will be thrown on the grid, increasing the chances of wins.
