Reactoonz Slot: Free Play Demo, Expert Review & Bonus Features Guide
Reactoonz is a video slot from Play’n GO and one of the most popular games the provider has made so far. It is also one of the best-looking ones, keeping a fresh look for modern standards despite being released in 2017. It has also spawned a sequel, Reactoonz 2, and spin-offs like Gargantoonz and Dr. Toonz.
The game has a large 7×7 grid and no paylines because it relies on the cluster pays mechanic for recording wins. More than that, the slot features the cascading wins mechanic as well.
There are no Reactoonz slot free spins, but the game has a bunch of special features, like the Gargantoon monster, a 3×3 symbol that acts as a massive wild. That’s just the tip of the iceberg, and we’ll explain it all in this Reactoonz slot review, so keep reading.

Reactoonz Slot Details
The slot features a large grid with seven reels, seven rows, and no paylines. It pays when at least five identical symbols connect horizontally, vertically, or both anywhere on the grid. The more you connect, the higher the payout which is great for beginners who want to learn how to play Reactoonz.
The Reactoonz max win is set at 4,570x stake, and with the max bet being $100, the highest return on a single spin is $457,000.
Moreover, the game features the popular cascade mechanic, where winning symbols disappear and new ones take their place, effectively giving you additional chances to land matching combos. This happens for as long as you keep winning, so the potential for high rewards is always there.
You’ll find four low-paying and four high-paying symbols, all of which come in the shape of alien heads. There’s also a wild and the Gargantoon symbol, which sits next to the grid but can also appear on the reels and function as a wild in various configurations, including a 3×3 block.
If you want to learn how to play Reactoonz slot online, you also need to know about the multipliers. Whenever four identical symbols connect into a square, they become one larger symbol that awards you with a 2x multiplier. If it forms part of a winning combination, the multiplier will apply to the final win.
And if that weren’t enough, Reactoonz also selects a random one-eyed symbol on every spin and marks all its instances as fluctuating symbols. This means that if they become part of a winning combination, they’ll leave behind two wilds.
Reactoonz Theme and Design
The Reactoonz slot has a cute cartoonish alien theme where everything revolves around alien heads. The design is extremely high-quality, and the game looks fresh, even though it was released almost a decade ago.
Aliens come in orange, yellow, blue, green, and many other colors. The massive three-eyed Gargantoon always overlooks the grid, and he can enter the game or add wilds into the mix at any time. Wilds have a distinct spinning orb shape, which fully distinguishes them from the remaining symbols.

Special mechanics and bonus features always come with flashy visuals, while alien heads that are part of winning combinations disappear in a flash of energy.
High-paying symbols have two eyes and a more complex look, while low-paying symbols are slightly smaller, come with a single eye, and have simpler designs. This makes it very easy to tell the difference between them.
Bonus Features On Reactoonz Slot
Both Reactoonz slot free play and real-money versions will show you that the game is filled with bonus features. Let’s review them so you know what to expect:
- Quantum leap — The Quantum queue to the right of the grid fills up with every win and resets when you lose. Land wins from 25 symbols in a row, and it will add a random Quantum feature to the queue (up to four). On the fifth, the Gargantoon feature will activate. As soon as the winning streak ends, the queued-up Quantum features will start activating one by one. The best part is that the Quantum queue keeps filling up once the features start working their magic, so you can refill it again, all on a single spin. And now, here are the Quantum features you can get:
- Implosion — Turns 3–6 symbols into wilds and destroys the surrounding ones.
- Incision — Adds a wild into the center and creates an X shape on the grid with wilds that then turn into the same symbol as the initial wild.
- Demolition — Eliminates all one-eyed symbols on the grid.
- Alteration — Selects one one-eyed symbol and turns all its instances into another symbol.
- Gargantoon — The Gargantoon monster will appear on the grid when the Quantum queue is filled. It’s a 3×3-sized monster and acts as a wild. With every cascade, the monster will divide, first into 2×2 symbols and then into nine separate wilds.
- Instability — Gargantoon can drop 4–8 wilds at any point in the game, as long as it’s a non-winning spin, which will give you a chance to turn your luck around.

Naturally, the game also has bonus features, but we’ll cover those in a later part of this Reactoonz slot review.
Claim Your Reactoonz No Deposit Bonus
If you’re wondering how to play the Reactoonz slot for free, a no deposit bonus with free spins for this game can always be a good deal. Alternatively, a no deposit promotion with bonus funds that can be used on Reactoonz is equally good.
As the game is popular, there are always some casinos that offer no deposit free spins for it, and you can claim them just by registering an account on those platforms. These bonuses come with specific conditions, like the maximum cashout amount or wagering requirements, and you’ll have to meet these to withdraw the money you win from the game.
The promos are typically small, so expect 10, 20, or maybe even 50 free spins, but rarely more. The more spins you get, the stricter the bonus terms will be.
Whenever we find a Reactoonz no deposit bonus, we’ll make sure to list it here to give you a chance to claim it.
What Is The RTP & Volatility On Reactoonz Slot
The Return-to-Player percentage, or RTP for short, in Reactioonz is 96.51%. This is well within industry standards, just above average, and it will lead to you winning $96.51 for every $100 invested.
Naturally, the RTP shows what you can expect in the long run, but you can still face major differences from one playing session to another.
The slot has high volatility, too, meaning that it offers rare but high wins as opposed to frequent small wins, which are more common in low-volatility games.
Get Free Spins at Online Casinos for Reactoonz
Reactoonz may not have a free spin feature of its own, but due to the game’s popularity, you can still get a wide range of FS promotions for the slot at numerous online casinos.
In most cases, you’ll find these spins as parts of welcome deposit bonuses, which often offer a sizable match deposit bonus and 10 to 200 free spins on select games.
Besides that, you can also find free spin bonuses for existing players, including weekly free spins and those that come as rewards in loyalty programs.
If you can’t find any FS offers that cover Reactoonz, you can at least expect promos for other games in the series, most notably for Reactoonz 2.
Play Reactoonz Slot On Mobile
Simple slot games are always better on the go or from the comfort of your couch. That’s why it’s so important for developers to optimize slots for mobile screens, and Play’n GO has definitely done its part for Reactoonz.

You get to play the game via a browser or even a casino app if the platform you’re using has one. The game functions on any modern iOS or Android device.
As you can see in the image below, even the location of buttons and other elements is identical to the computer version. Naturally, you’ll probably prefer to play it in horizontal mode, as the window is too small in the standard vertical one.
