Reactoonz 2 (Play'n Go) Slot Review

Reactoonz 2: Slot Overview 

The googly-eyed alien gang is back—and they’re more electric than ever. Reactoonz 2, released by Play’n GO on October 1, 2020, is the sequel to one of the studio’s most iconic grid slots. Following in the orbit of the original Reactoonz, this sequel takes the same chaotic 7×7 Cluster Pays format and injects it with new features, updated visuals, and a multi-layered charge meter system that ups the ante significantly. 

While the core structure remains familiar—match five or more symbols in clusters to trigger cascading wins—there’s a deeper level of strategy and unpredictability this time. New mechanics like the Fluctometer, Electric Wilds, and a four-level Quantumeter bring added excitement and reward potential, culminating in the return of the colossal Gargantoon, Play’n GO’s most lovable monster. 

With a slightly adjusted RTP of 96.20%, high volatility (rated 8/10), and a boosted maximum win of 5,083x your stake, Reactoonz 2 doesn’t reinvent the wheel—but it definitely puts a turbo engine under the hood.

Design and Graphics 

Reactoonz 2 maintains the vibrant cartoon aesthetic of its predecessor but gives it a slick, modern refresh. The 7×7 grid floats in front of a galactic-blue background, creating a lighter, more sterile lab-like atmosphere than the original’s darker lab setting. On either side of the grid, animated meters and reactors glow, flicker, and pulse with activity as wins pile up and features charge. The alien symbols return in full force—adorably odd, color-coded, and expressive. The one-eyed and two-eyed characters wiggle and bounce with personality, especially when you start triggering features. Their simple animations help players easily track clusters and potential combos. 

The Gargantoon once again steals the show when unleashed, stomping onto the grid with satisfying force. The visual effects—electric sparks, neon glows, and sudden symbol wipes—are impressively fluid and tie the whole interstellar theme together with polish.

Gameplay Mechanics 

At its core, Reactoonz 2 sticks to the cluster pays + cascading wins mechanic. Players win by landing clusters of five or more matching symbols, which are then removed from the grid, causing new ones to cascade down and possibly trigger chain reactions. 

However, Reactoonz 2 builds on this core with several important enhancements: 

Fluctometer 

A randomly chosen one-eyed symbol is designated as the fluctuating symbol on each spin. 

If a win includes the fluctuating symbol, Electric Wilds are added to the Fluctometer. 

When the Fluctometer fills, 1–3 Electric Wilds are added to the grid. 

This meter can recharge multiple times, unless the Gargantoon is triggered. 

Electric Wilds 

Wilds appear via Fluctometer or cascades. 

They substitute for all pay symbols and zap nearby symbols to help fill the Quantumeter. 

They also power a key feature: Wild Pair Explosion (more below). 

Quantumeter 

The Quantumeter tracks symbols removed by Electric Wilds. 

It unlocks special wild-based rewards when charged to specific thresholds: 

Level 1 (55 charges) – Four 1×1 Energoon Wilds 

Level 2 (85 charges) – One 2×2 Energoon Wild 

Level 3 (110 charges) – One 3×3 Gargantoon Wild 

Level 4 (135 charges) – Adds a 2x multiplier to all wins from the Gargantoon 

The Quantumeter deactivates once a Gargantoon is released. 

Gargantoon Evolution 

Once released, the 3×3 Gargantoon triggers one of the most powerful sequences: 

Appears as a 3×3 Wild 

Breaks into two 2×2 Gargantoon Wilds 

Finally, breaks into nine 1×1 Gargantoon Wilds 

Each step occurs after a cascade, dramatically increasing win potential. 

Wild Pair Explosion 

If no other features are active and two or more Electric Wilds remain on the grid: 

If adjacent, all symbols except wilds are removed. 

If not adjacent, the game selects a midpoint between them and destroys surrounding symbols. 

Symbols destroyed here also help charge the Quantumeter. 

These features work together to produce thrilling gameplay loops that can swing from dry spells to explosive win chains in seconds.

Sound and Music 

Reactoonz 2 keeps the spirit of the original soundtrack but dials things up with extra zaps, ambient flourishes, and high-energy sound cues. The music is light and synth-driven, giving a bouncy, playful feel that pairs perfectly with the chaos on screen. 

Cascades, meter charges, and wild activations come with satisfying sound effects—sizzling sparks, bubbling bleeps, and mechanical hums that emphasize the alien lab vibe. When the Gargantoon drops, the soundtrack swells with drama, adding gravity to the moment. 

Each win feels reactive and celebratory without becoming overwhelming, even during wild chain reactions.

Bonus Features 

Rather than traditional free spins or bonus rounds, Reactoonz 2 builds all its depth directly into the base game via its multiple meters and wild mechanics. Key Features Recap: 

Fluctometer: Adds Electric Wilds to the grid after fluctuating symbol wins. 

Electric Wilds: Trigger Quantumeter charges and substitute for any symbol. 

Quantumeter: Four-tiered charge meter that releases wilds and eventually the Gargantoon. 

Gargantoon: 3×3 Wild that evolves through smaller wild forms with multipliers at the highest level. 

Wild Pair Explosion: Clears the board to rescue losing spins and boost the Quantumeter. 

The interlocking nature of these systems rewards patience and pattern recognition, keeping players constantly engaged with the next meter threshold.

Betting Options and Payouts 

Reactoonz 2 is designed for flexibility. Players can spin from €0.20 to €100 per spin, covering a wide range of bankrolls. Like its predecessor, the game doesn’t offer huge symbol payouts on their own—instead, it’s about stacking cascading wins and unlocking wild-driven bonuses. 

Symbol payouts: 

• Clusters of 15+ symbols are the most lucrative, offering between 3x to 500x the stake depending on the symbol. 

• The uncharged wilds don’t form wins themselves but act as conduits for Electric Wild generation. 

The game’s maximum win is 5,083x, a modest bump over the original. That said, it’s a long shot—the win probability is just 3.717e-15, underlining the game’s high volatility.

Conclusion 

Reactoonz 2 builds on a beloved formula and manages to add just enough to feel fresh without alienating fans of the original. Its multi-layered systems—from Fluctometer to Quantumeter to Gargantoon Evolution—create an energetic, evolving gameplay loop that rarely feels stale. 

While some players might feel overwhelmed by the complexity at first, the game quickly reveals its logic with a few spins. And once you understand how the meters interact and stack, it becomes a highly engaging, skill-driven slot with real depth. 

That said, it doesn’t quite reinvent the genre, and comparisons to Reactoonz 1 are inevitable. Some may find the changes too incremental or the presentation a little too familiar. But judged on its own merits, Reactoonz 2 is a high-quality, high-volatility grid slot that packs in action, polish, and plenty of personality.
