  • The slot machine has a colorful interface and you can find all the controls arranged at the bottom panel.

  • You will be having a demo balance of 25000 to play with. Next, to your balance tab, you can find various bet sizes to choose from. There are plus and minus symbols on either side of the bet sizes. By clicking on these symbols you can increase or decrease your stakes.

  • The minimum bet value is 0.20 and the maximum is 100. Once you choose your bet value you can spin the reels by clicking on the big green button with arrows on it. 

  • Next, to the spin button, there is a smaller yellow button which is for activating the auto play option. You can fix the number of spins you need or make customizations like spinning the reels until you get any wins.

  • Below the Spin button, you have an option “play for real”. Whenever you wish to switch to the real-money mode you can select this option.

Game Features

The cascading video slot has lots of user-friendly features that allow the players to optimize their spins in various ways. The notable features of the slot machine are as follows:

  • The game has a charge meter on the right side of the grid that charges up whenever the grid offers a winning combination. Once it is fully charged, it triggers various Quantum features.

  • On the left side, there is a box that highlights the results of every spin. All the wins and the combination of characters that appear on the grid are displayed in this box.

  • Just below the charge meter, there is a 3-eyed sleeping alien character which is known as Gargantoon. It may drop random wilds as you spin the reels and help you win some amazing prizes.

  • On the bottom left corner, you can find the symbol “I” which is a link to all the information about the payout features.

  • On the bottom right corner, you can find a yellow button which is the AutoPlay option for the game. It is a very useful feature that allows you to make several adjustments.

  • On the extreme left corner of the screen, you can find the settings option denoted by three small horizontal lines. By clicking on it you can open the settings window. Here you can find the toggle bars to turn on options like sound, auto adjust bets, Fast Play, and ‘Spacebar to Spin’. You can also find direct controls for Fast Play and Sound options next to the settings symbol on the bottom panel.

  • For more details about the gaming features, you can click on the small “question mark” symbol at the bottom panel.


Besides the three-eyed Gargantoon, the game has 8 symbols of various colors. Among these 4 are double-eyed symbols and the rest are one-eyed symbols. The pink double-eyed symbol is the highest paying symbol. You need at least 5 of each symbol to get a winning combination. The other double-eyed symbols are green, red, and blue in color and they attach different values when the wins are calculated.

Game Rules

Knowing the game rules can always make you a better player. And in the case of slots like Reactoonz that involves lots of extra features, knowing the rules can definitely improve your winning chances.

  • The game doesn’t have any paylines that you often find in other video slots. Wins occur when 5 or more similar symbols land in a cluster and connect with each other either horizontally or vertically.

  • The winning combination is immediately removed and its space is filled up by symbols that fall down from the top rows. This can again trigger a new set of winning combination.

  •  Every time the grid offers a winning combination, the 5 Quantum Leap meter gets charged. Once it gets fully charged, a quantum feature is queued up. The 4 quantum features are Implosion, Alteration, Demolition, and Incision.

  • In an implosion, 3 to 6 symbols get converted to wilds and all the adjacent symbols are destroyed. The process is accompanied by added wins.

  • In demolition, all one-eyed and matching symbols are destroyed and new symbols take their place.

  • In alteration, the grid randomly picks a one-eyed symbol and thereby converts all matching symbols to trigger some extra wins.

  • In incision, 2 diagonal lines intersect each other with a wild in the center and all the symbols that fall in the way are destroyed.

  • Once the meters are charged, the Gargantoon feature is queued up. It randomly adds a set of wild symbols that get destroyed to trigger new wins. As the wilds burst into fire, they are replaced by cascading symbols.

  • Once the Gargantoon feature concludes the quantum features get triggered one after the other. As the round ends, the charge meters get fully reset. And once again you have to start spinning the reels to charge them up.

  • A Giantoonz is formed if you get 4 matching symbols in a square shape. If one or more Giantoonzs occur in a winning combination, the wins are instantly doubled.

  • In every spin, a one-eyed symbol is deemed as a fluctuating symbol. And if such a symbol occurs in a winning combination, it generates 2 wild symbols which in turn work as substitutes for other symbols.


The payouts are based on the winning combinations that appear on the grid. When 5 or more identical symbols appear in a cluster, the wins are rewarded. The symbols can occur in different patterns but they have to be connected either horizontally or vertically or both. As you start with the gaming session, the Instability feature of the game lets the Gargantoon bring 4 to 8 wilds on any non-winning spin. But the Gargantoon feature is triggered when you win different bonus features that charge the Quantum meters. 


Once you win on 25 symbols, a Quantum feature is randomly added to the meter. After you have 4 such features queued up when the meter gets charged for the 5th time the Gargantoon feature is activated. As up play another non-winning spin, the features get triggered one by one rewarding you with a big win. The game has been named as Reactoonz owing to the spontaneous nature in which the wins are triggered.


Among the double-eyed symbols, pink one can bring maximum payouts. If you get 15 or more of this symbol, you can win up to 1200 points. This followed by green, red and blue in the descending order of their values. 


RTP and Variance

When it comes to RTP percentage, Reactoonz can be entitled to some high ratings. Based on the gameplay, the average RTP of the game is estimated to be 96.51%. The exciting slot game is also known for its high level of variance. In other words, the size of the wins is generally small and mega wins tend to occur only on an occasional basis and are often triggered by the Quantum leap feature. Nevertheless, players can expect to enjoy marginal gains in return for placing bets consistently.

Game Review

Before you play any game for real money you should check the reviews and ratings enjoyed by the title. There are several candid slot review sites that offer unbiased data about the history of various casino games. In the case of Reactoonz, the manufacturers have incorporated cascading gameplay. The main advantage of the style is that it allows the gamers to grab multiple wins on a single bet. With a minimum stake of £0.20 players stand a chance to win up to 4570 times the bet money. In other words, if you play with higher bet values, you have a better chance to end up with a huge win.

The unique feature of the title is its Quantum leap meter that prepares itself with the small wins earned by the player. Once the meter is fully charged it would reward the player with some impressive wins. In short, players can recover the money they have lost on initial bets when the bonus features are triggered.


Unfinished Session

Before you choose any slot you should check how a session timeout can affect your proceedings. Reactoonz may get disrupted if you are inactive for several minutes. However, all the bets placed and winnings would be saved as it is and you can continue the unfinished round by reopening the game. However, you should also check the policies followed by your casino in the case of a session timeout. In the case of any malfunction or attempts to manipulate the results, all the payouts get automatically canceled.


  • The game has a vibrant alien theme that can excite the player with its electrifying hues and background design.

  • The gameplay is something unique and interesting when compared to other slot games that have a predictable and monotonous style of working.

  • The Jackpot wins are quite huge and the user can win a maximum of up to 457030 points.
