Reactoonz Slot Description

Reactoonz is a popular cascading slot game developed by Play’n GO, and is played on a grid with a packed 7x7 layout. One of the first things you’ll notice about this slot is the amazing presentation, particularly the adorable characters filling the screen.

These little monsters are bright, colourful, and designed brilliantly. Each looks unique, with its own colours and features to help players distinguish one from the other. This set of symbols also makes a refreshing change to the usual ones seasoned slots players have probably seen countless times (e.g. K, Q, J, etc.).

This slot online includes a terrific roster of bonus features and mechanics that help it stand out. These also can create additional winning opportunities and boost the value of prizes.

Reactoonz is a great example of how to make a slot game with its own personality and style, but still keep it accessible to newcomers

How to Play Reactoonz Slot Machine

Reactoonz is simple to play, as with most slots, and Play’n GO has done a fantastic job implementing various special features. The aim of the game is to create as many winning combinations as you can and claim prizes, with different symbols leading to different prizes.

Seven monsters appear vertically and horizontally, with up to 49 on screen at any one time. Five or more symbols are required to activate a win: they must be connected either vertically or horizontally to count as a cluster. When a winning line-up is created, those symbols will be removed so new ones can drop in to take their place.

If four matching symbols land adjacent to each other on the grid, forming a square, they will merge together to form Giantoonz. Wins will be doubled while at least one Giantoonz is part of winning combinations.

Each of the symbols pays out a specific amount. The high-paying symbols have two eyes, while the low-paying symbols have just one. This simple labelling system helps you to recognise when you’re likely to form a winning combination.

The control panel beneath the grid includes standard buttons to play Reactoonz: balance, bet, etc. You can spin the reels by clicking/tapping the green ‘spin’ button to the right of the panel. Alternatively, you can take advantage of the autoplay feature and watch the game play itself for a while instead.

Reactoonz Free Spins?

Play’n GO has chosen not to include a free spins feature in Reactoonz, but there are numerous other bonus features to try.

But don’t worry — at Spin Genie, we award newcomers 108 free spins when you sign up and make your first deposit. This is a terrific opportunity to try some of our slots with free play, helping your own money go further.

More Reactoonz Features

Wild symbol

In Reactoonz, the wild symbol is a swirling multicoloured vortex. This can replace any other symbol on the grid to help form winning combinations.

Special wild (Gargantoon)

This 3x3 monster symbol appears during the Gargantoon feature, and can replace all other symbols on the grid.

Quantum Leap Charge Meter

When wins are created across the grid, the Quantum Leap Charge Meter fills up more and more. This is made up of five parts, and 125 consecutive wins are required to fill all five parts of the meter. 25 wins in a row are required to fill one part and activate a feature at random. When all five parts become filled, the Gargantoon feature will begin.


During this feature, between three and six symbols are transformed into wilds. All the symbols surrounding these are taken away and new ones drop down to replace them.


One low-paying symbol is selected randomly and all matching symbols transform into a different one. If no low-paying symbols are available when this is triggered, any other symbol will be chosen instead.


This feature removes all of the low-paying symbols and those that match.


This places a wild into the screen’s centre as two intersecting lines will appear across the grid, and the same random symbol remains in position.


If no winnings are achieved in the base Reactoonz game, the Gargantoon feature may introduce between four and eight wilds across the reels.

Fluctuating symbols

On each cascade, one of the low-paying symbols (one-eyed monsters) is selected at random. If this forms part of a winning combination, two wilds will be left behind to create more winning opportunities.

If you don’t create a win, the wilds will vanish and the next cascade will unfold.

Our Reactoonz Slot Review

Reactoonz is a stunning online slot machine with plenty to recommend it. The presentation is outstanding in all respects, with the monsters helping to give the game a bit more personality than some other slots. The bonus features (such as those triggered by the Quantum Leap Charge Meter) add more depth and create a sense of progression.
