Reactoonz 2 Slot Demo
Reactoonz 2 from Play’n GO is a high-volatility slot set across a 7×7 grid that builds on the massive success of its predecessor. With a quirky alien theme, an RTP of 96.20%, and some cluster-based mechanics, there’s plenty to explore here.
Join us as we drill down past the quirky visuals and electrifying gameplay in this Reactoonz 2 slot demo and review.
Our Verdict on Reactoonz 2 – Feature Score: 9.1/10
After playing Reactoonz 2 extensively, I can confidently say it’s one of the most entertaining and dynamic slots I’ve encountered in a while. The cascading reels, quirky alien characters, and charged bonus features kept me glued to the screen. What stood out most for me was the Electric Wilds feature, which helps to keep the gameplay unpredictable and rewarding.
If you’re looking for a high-volatility game with layered mechanics and a sense of progression, Reacactoonz 2 is a great pick. If you enjoyed the original Reactoonz or games like Jammin’ Jars, you’ll certainly feel right at home here.
However, the steep learning curve might be daunting for newbies. I’d suggest playing our Ractoonz 2 demo first to familiarise yourself with the game’s sometimes confusing mechanics first.
The variety of quirky features, entertaining visuals, and huge max win potential of 5,083x make Reactoonz 2 a standout slot. The only minor drawback is its complexity, which might put off some casual casino players.

Gameplay Overview
Getting started with Reactoonz 2 is a breeze, even if you are new to this alien-laden title. Here’s a quick guide to get you spinning in no time:
Set Your Bet
Adjust your wager using the plus and minus controls below the grid, or tap on one of the bet amounts. Bets range from as little as £0.20 to a maximum of £100 per spin.
Hit Spin
Tap the spin button to the right of the reels and set the quirky alien-filled reels into motion. Alternatively, use the Autoplay feature to let the game handle multiple spins for you. You can stop this anytime you like or set it to stop anytime you land a win.
Build Those Clusters
Land clusters of five or more matching symbols horizontally or vertically. Each win triggers a cascade, offering a chance to chain multiple wins together.
Trigger Special Features
Keep an eye on the meters to the right of the reels. Filing these with trigger special features like Electric Wilds and the Fluctometer to supercharge your gameplay.
Core Mechanics and Symbols
- Fluctuating Symbols: At the start of each spin, one low-paying one-eyed symbol is randomly chosen to fluctuate. Winning clusters of five or more fluctuating symbols evaporate and leave behind Electric Wilds and charge the Fluctometer.
- Electric Wilds: These substitute for any regular symbol and zap other symbols, which charges up the Quantumeter.
- Special Symbols: Look out for the quirky Reactoonz and Gargantoon characters, which trigger features when the Quantumeter is fully charged.
The Quantumeter and Fluctometer
Fluctometer: Filling this meter (by landing wins with fluctuating symbols) randomly adds 1-3 Electric Wilds to the grid. It resets after use but stops functioning if the Gargantoon feature is active.
Quantumeter: Charged by non-wild symbols zapped by Electric Wilds. Reaching specific thresholds (55, 85, 110, or 135 charges) unlocks four levels of wild features:
- Level 1: Four 1×1 Energoon wilds.
- Level 2: One 2×2 Energoon wild.
- Level 3: A 3×3 Gargantoon wild.
- Level 4: A 2x multiplier on all wins.
Wild Pair Explosion
If two or more Electric Wilds remain on the grid after cascades and other features are complete, the Wild Pair Explosion activates:
- Adjacent Wilds: Clear all non-wild symbols from the grid, creating potential for new clusters.
- Separated Wilds: Destroy symbols between and around them, charging the Quantumeter in the process.

Reactoonz 2 Visuals and Theme
You’ll be hard-pushed not to smile when those jolly little critters start tumbling down the reels in Reactoonz 2. It’s crazy how the little Minion-like aliens all have distinct personalities, despite not being much more than eyes and mouths. The team at Play’n GO have really cracked the quirky visuals on this one!
The animations really kick this slot into life, especially when combined with the pumping soundtrack and electric sounds. I particularly like how the audio jumps up a notch when the symbol combinations begin to stack up, and the features trigger.
RTP and Volatility
Reactoonz 2’s RTP is 96.2%, just a smidge above the industry standard of 96%. This slot has high volatility, meaning that payouts may be less frequent but more substantial when they do land.
This matches up with my testing, as I experienced quite a few runs of spins where I only landed the occasional one-eyed critter. Therefore, this slot is one for casino players who enjoy taking risks for big rewards, but you’ll need some solid budget management to see you through any winless streaks.
Reactoonz 2 Mobile Compatibility
I tested Reactoonz 2 on my iPhone 13 Mini and a Pixel 7a to get a true feel for the slot’s performance on both iOS and Android devices. I’m happy to report that there was no lag or glitching, and the game’s performance was flawless on both.
The touch controls are just as responsive, and the colourful little aliens lose none of their charm on smaller screens. Whether you’re commuting or relaxing at home, this game adapts perfectly to some mobile gameplay, all you need is a solid data connection.
