When Play’n GO announced Reactoonz 2, the entire casino community waited to see if they could improve on the original, which was already iconic. And you know what? They succeeded. Reactoonz 2 is not just a cosmetic upgrade – it’s a completely redesigned game with new mechanics, features, and even greater winning potential. If you are looking for detailed information on how to play Reactoonz 2 specifically on the **Mostbet platform** in the Czech Republic and how it differs from the original, you are exactly where you need to be. In this article, we’ll dive into all aspects – from the new Fluctometer system to Electric Wilds and the strategies that will help you maximize your chances for those truly massive wins.
Reactoonz 2 retains the best of the original (Cluster Pays system, $7\text{x}7$ grid, adorable aliens), but adds layers of new features that take the game to a completely different level. Here you have **Energoon** – a new giant alien, the **Fluctometer**, which replaces the original Quantum Meter, and **Electric Wilds**, which create entirely new possibilities for big wins. Is it more complex than the original? A little. But it is that complexity that makes Reactoonz 2 a game that will keep you entertained for hundreds, maybe thousands of spins. On Mostbet, you also have access to a demo version, bonuses, and great mobile optimization. Get ready to return to the universe of alien reactions, this time with a turbo boost.
What’s New in Reactoonz 2 Compared to the Original
The first question everyone asks is: how much does Reactoonz 2 differ from the original? At first glance, they look similar – the same $7\text{x}7$ grid, the same Cluster Pays system, even the symbols look similar (although they have a new design). But when you start playing, you quickly find that the mechanics are significantly different.
The biggest change is the **Fluctometer**, which replaces the original Quantum Meter. Instead of filling one meter, you now have four different levels, each with its own type of wild symbols. And then there’s **Energoon** – a gigantic $2\text{x}2$ symbol that can randomly appear during the game and which, when you remove it, activates special features. It’s like Play’n GO took the original Reactoonz and said, “What if we made it even crazier?”
I personally really like the original Reactoonz, but I have to admit that Reactoonz 2 has something in it that draws me in even more. The unpredictability of how Energoon can change everything in a single moment creates a tension that is simply addictive. And Electric Wilds? We’ll talk about them later, but they are little pieces of magic.

Technical Parameters – The Numbers You Must Know
Reactoonz 2 has an RTP (Return to Player) of $96.20\%$, which is slightly lower than the original ($96.51\%$), but still a decent value. The **volatility is high**, perhaps even slightly higher than the original, meaning longer periods without wins, but potentially bigger hits when wins do come. The **maximum win is $5083\text{x}$** your bet, which is an improvement over the original ($4570\text{x}$).
The minimum bet starts at $0.20$ € (about $5$ CZK) and the maximum is $100$ € (about $2500$ CZK). The range is identical to the original. The hit frequency is similar, but thanks to the new features, you feel like more action is happening, even if the numbers are comparable.
| Parameter | Reactoonz | Reactoonz 2 |
|---|---|---|
| RTP | $96.51\%$ | $96.20\%$ |
| Volatilita | High | High |
| Max. win | $4570\text{x}$ | $5083\text{x}$ |
| Game grid | $7\text{x}7$ | $7\text{x}7$ |
| Min. bet | $0.20$ € | $0.20$ € |
| Max. bet | $100$ € | $100$ € |
| Year of release | $2017$ | $2020$ |
Fluctometer and the New Wild Symbol System
This is where Reactoonz 2 truly shines. The **Fluctometer** is a four-level meter on the right side of the screen that fills up by removing symbols, similar to the Quantum Meter in the original. But instead of activating random features, the Fluctometer gradually unlocks different types of **wild symbols** that then appear during the game.
You have four types of wilds: $1$-socket wilds (basic), $2$-socket wilds (better), $3$-socket wilds (even better), and $4$-socket wilds (the best). The more symbols you remove during a single spin (including cascades), the higher the Fluctometer level you reach and the stronger the wilds that appear. And when you fill all four levels, **Rantoonz** is activated – a special feature that adds extra wilds all over the grid.
How Electric Wilds Work
**Electric Wilds** are a new type of wild specific to Reactoonz 2. When a wild is created (in any way), it has a chance to become an Electric Wild. An Electric Wild has blue electrical effects around it, and when it’s part of a winning cluster, it **spreads to all adjacent positions** (horizontally, vertically, and diagonally) and turns them into wilds too.
I’ve seen situations where one Electric Wild led to a chain reaction that turned half the grid into wilds. That’s the moment when you can achieve those truly big wins – $200\text{x}$, $300\text{x}$, sometimes even more. Electric Wilds are my favorite part of Reactoonz 2 because they add an element of unpredictability that can completely change the course of the game.

Energoon – A New Giant Symbol That Changes the Game
If Gargantoon was the star of the original, **Energoon** is the superstar of Reactoonz 2. It’s a gigantic $2\text{x}2$ symbol that can randomly appear on the grid at any time during the game (not just after filling the meter like Gargantoon). When Energoon appears, it occupies four positions, and you can only remove it by creating a winning cluster that touches it.
When you remove Energoon, it splits into four $1\text{x}1$ symbols, and each of them can become a wild symbol. But that’s not all – Energoon also adds charges to the Fluctometer, meaning it moves you faster to higher wild levels. Essentially, Energoon is a **catalyst for big wins**. When I see Energoon on the grid, my pulse always rises because I know big things can happen.
Strategies for Utilizing Energoon
Energoon appears randomly, and you cannot influence its arrival. But you can adjust your betting approach based on what’s happening on the grid. When I see Energoon in the middle of a promising situation (for example, with several clusters on the grid), that’s the moment I wish I had a slightly higher bet. But of course, it doesn’t work like you should increase your bet every time Energoon appears – that would be a path to bankruptcy.
My approach is **consistent betting** with occasional increases when I’m in profit. I simply see Energoon as a bonus feature that can come at any time, and I try to stay on the grid long enough to have a chance to see it in action multiple times. With high volatility, this means solid bankroll management, which we will talk about in a moment.
“Reactoonz 2 is proof that a sequel can be better than the original. Play’n GO added exactly the right innovations – Energoon, Electric Wilds, improved Fluctometer – without losing the soul of the original.” – From casino expert reviews

Symbols and Paytable of Reactoonz 2
The symbols in Reactoonz 2 are similar to the original, but have a new visual design – they look more modern and detailed. You still have one-eyed and two-eyed aliens in four colors (pink, blue, green, orange). The two-eyed ones are more valuable than the one-eyed ones, and the highest symbol is the pink two-eyed alien.
The pay system is based on the **size of the cluster**. The minimum winning cluster is $5$ symbols, but the larger the cluster you create, the more you win. A cluster of $15$ or more symbols can pay out up to $750\text{x}$ per cluster (for the highest symbol). And since you can have multiple clusters at once, the total winnings can be truly impressive.
How to Maximize Cluster Value
The key to big wins in Reactoonz 2 is creating **large clusters**, not necessarily many small ones. One cluster of $20$ symbols pays out much more than four clusters of $5$ symbols. Wild symbols are your best friends here because they help connect clusters together.
Electric Wilds are especially valuable because they can transform an average cluster into a massive one. Imagine a situation: you have a cluster of $8$ symbols, an Electric Wild appears in the middle, spreads to adjacent positions, and suddenly you have a cluster of $15+$ symbols. That is the difference between a $20\text{x}$ win and a $150\text{x}$ win. That’s why Electric Wilds make Reactoonz 2 such an exciting game.
Reactoonz 2 on the Mostbet Platform – Access and Advantages
Mostbet offers Reactoonz 2 as part of its extensive Play’n GO portfolio. You can start in **demo mode** completely free of charge (without registration) or create an account and play for real money. Registration is standard – email, password, identity confirmation. The whole process takes a few minutes, and you can start.
Payment methods are suitable for Czech players. Cards (Visa, Mastercard), bank transfers, e-wallets – all standard and reliable. Deposits are instant, withdrawals are usually processed within $24$ hours. I personally have never had a problem with the processing speed at Mostbet – it works smoothly.
Bonuses and How to Use Them Effectively
Mostbet regularly offers welcome packages that include first deposit bonuses and sometimes free spins. Free spins are often limited to specific games, but you can use **bonus money** on any game, including Reactoonz 2. This is good news, because with high volatility, every extra money in the bankroll helps.
Watch the **wagering requirements** – usually $30-40\text{x}$, which means you have to wager the bonus several times before you can withdraw the winnings. And check the maximum bet per spin while fulfilling the wagering. It is often limited to $25$ CZK or a similar amount, which is not a problem with Reactoonz 2 with a minimum bet of $5$ CZK.
In addition to welcome bonuses, follow the “Promotions” or “Tournaments” section. Mostbet occasionally organizes special events focused on Play’n GO games where you can compete for extra prizes. And cashback offers are also useful – if you have bad luck and lose, you get a portion back, which extends your playing time.
Advanced Strategies for Reactoonz 2
Reactoonz 2 is a game that rewards **patience and smart bankroll management**. With high volatility and complex mechanics, you can’t just press spin and hope for the best. You need a plan. Here is my personal approach, which I developed after hundreds of hours of playing.
Bankroll Management for Extreme Volatility
With Reactoonz 2, I recommend having a bankroll that covers a minimum of **$250-400$ spins**. Yes, that is a lot. But with how volatile this game is, you need that reserve. If you want to bet $5$ CZK per spin, you should have at least $1250-2000$ CZK available. This gives you room to withstand even really long dry periods.
I personally use the “**rule of $300$**” – I always have a bankroll for $300$ spins. When I start with $1500$ CZK, I bet $5$ CZK per spin. When I reach $3000$ CZK (doubling), I set aside a part (e.g., $1200$ CZK as pure profit) and I can be more aggressive with the rest – I increase the bet to $7-8$ CZK per spin. If it works out and I earn more, great. If not, I still have that original profit.
When to Play Aggressively and When Conservatively
My rule is simple: I play conservatively (minimum bets) until I see a series of action on the grid – Energoon, Electric Wilds, high Fluctometer levels. When I see the game “**giving**” (which you recognize after a series of decent wins), that’s the moment I can slightly increase the bet.
Conversely, when I go through $50-100$ spins with minimal or no wins, I lower the bet to the absolute minimum or take a break. There is no reason to push when things are not going well. And I definitely never do the classic “**doubling down**” after a big loss. That is a self-destructive strategy no matter what game you are playing.

Reactoonz vs Reactoonz 2 – Which Game is Better?
This is a question I get all the time. The answer? It depends on what you are looking for. Let’s look at the main differences and what each slot does better.
| Aspect | Reactoonz | Reactoonz 2 |
|---|---|---|
| RTP | $96.51\%$ | $96.20\%$ |
| Max. win | $4570\text{x}$ | $5083\text{x}$ |
| Main feature | Gargantoon, Quantum features | Energoon, Electric Wilds, Fluctometer |
| Volatility | High | High (slightly higher) |
| Complexity | High | Very high |
| Visual style | Classic | More modern |
The original Reactoonz has a higher RTP and perhaps slightly lower volatility. It’s a “**cleaner**” experience with fewer layers of features. Reactoonz 2 has a lower RTP, but a higher max. win and more complex gameplay thanks to Energoon and Electric Wilds. I personally like to play both – when I want to relax a bit, I go for the original. When I want maximum action and excitement, I choose Reactoonz 2.
Mobile Version and Cross-Platform Optimization
Reactoonz 2 is **fully optimized for mobile devices** and works perfectly on all platforms. Play’n GO did a great job with optimization – the game runs smoothly even on older phones. Whether you use an iPhone, Android, or tablet, the experience is practically identical to the desktop.
On Mostbet, you can play via the mobile app or the responsive web. I prefer the app – it’s faster and has better UX. The $7\text{x}7$ grid fits perfectly on the mobile screen without the need to zoom in. All animations – Energoon, Electric Wilds, cascades – are just as smooth as on the desktop.
One thing I appreciate: the touch control is intuitive. You tap to spin, you can turn on autoplay with one click, everything responds instantly. And the graphics? It looks amazing even on a smaller screen. Those colorful aliens and electrical effects are simply made for modern smartphones with OLED displays.
Frequently Asked Questions about Reactoonz 2 on Mostbet
Is Reactoonz 2 better than the original Reactoonz?
It depends on your preferences. Reactoonz 2 has more complex gameplay, a higher max. win ($5083\text{x}$ vs $4570\text{x}$) and new features like Energoon and Electric Wilds. But it also has a lower RTP ($96.20\%$ vs $96.51\%$). If you prefer more action and don’t mind the higher volatility, Reactoonz 2 is the better choice. If you want a simpler experience with a higher RTP, stick to the original.
How often does Energoon appear?
Energoon appears randomly, approximately **once every $30-60$ spins** in my experience. It’s not as rare as Gargantoon in the original. That’s why Reactoonz 2 is so dynamic – you have a constant chance for Energoon, which can fundamentally change the situation on the grid.
What is the optimal bet for Reactoonz 2?
That depends on your bankroll and risk tolerance. With very high volatility, I recommend betting a maximum of $0.25-0.4\%$ of your total bankroll per spin. If you have $2000$ CZK, bet $5-8$ CZK per spin. This gives you room to withstand long dry periods without the risk of losing everything.
Can I play Reactoonz 2 for free?
Yes, a **demo version** of Reactoonz 2 is available on Mostbet completely free of charge. You do not need to register or deposit money. The demo uses virtual credits and is perfect for getting acquainted with the game mechanics, testing strategies, or simply for risk-free fun.
How does the Fluctometer work and when does Rantoonz activate?
The Fluctometer is a four-level meter that fills up by removing symbols during a spin and its cascades. Each level unlocks better types of wilds. When you fill all four levels during a single spin, **Rantoonz** is activated – a special feature that adds extra wilds across the grid. Rantoonz is relatively rare (roughly once every $200-300$ spins), but when it appears, it often leads to big wins.
Final Summary and Recommendations
Reactoonz 2 is proof that Play’n GO can create a sequel that is not just a redesign of the original, but a genuine improvement. New features like Energoon, Electric Wilds, and the improved Fluctometer system add layers of strategic depth and excitement that the original simply didn’t have. The $96.20\%$ RTP is solid, the maximum win of $5083\text{x}$ is attractive, and the high volatility means the potential for those truly big hits that make online slots so exciting.
On the Mostbet platform, you have all the advantages – a demo version for risk-free testing, bonuses to extend your playing time, fast and reliable payment methods, and perfect mobile optimization. Reactoonz 2 is not a game for the faint of heart – the complexity and high volatility can be daunting for some players. You need a solid bankroll, patience, and a willingness to learn all the mechanics. But if you’re looking for one of the most unique and entertaining games in the entire casino world, you’ll be hard-pressed to find a better choice.
If Reactoonz 2 has caught your attention, **start in demo mode**. Play a minimum of $300-500$ spins to understand how the Fluctometer works, see Energoon in action, and experience Electric Wilds. Only then switch to real money and start with conservative bets. Watch the bonus offers at Mostbet – every extra crown in the bankroll helps with high volatility. And remember – online slots are primarily entertainment. Play responsibly, enjoy this crazy universe of alien reactions version $2.0$, and may Energoon bring you the best wins!
