This guide explores every aspect of the Reactoonz universe, from fundamental gameplay elements to advanced features like the Quantum Leap meter and the powerful Gargantoon bonuses. Whether you're taking your first steps into grid-based slots or seeking to refine your existing strategy, you'll discover the secrets behind this game's most rewarding features.
Getting Started with Reactoonz
Play'n GO's Reactoonz welcomes players to a stellar-powered parallel universe. Since its 2017 debut, this grid slot's innovative gameplay approach has mesmerized slot enthusiasts worldwide.

Basic Game Setup
The game's betting structure caters to every player's comfort level. Wagers range from a modest $0.20 to an impressive $100 per spin. Players benefit from quality-of-life features, including an autoplay option supporting up to 100 consecutive spins and a lightning-quick turbo mode.
Understanding the 7x7 Grid
Reactoonz replaces conventional slot reels with a spacious 7x7 grid, where colorful alien characters descend from above to fill positions. The game's high volatility design delivers less frequent but more substantial payouts. Traditional paylines make way for an entirely fresh gaming approach.
How Winning Clusters Work
Winning combinations in Reactoonz emerge through cluster pays mechanics. Players need five or more matching symbols, connected horizontally or vertically, to secure wins. Successful combinations trigger a cascading effect, where winning symbols vanish. Fresh symbols then tumble down, potentially sparking new winning clusters within the same spin.
The game introduces an exciting Giantoonz feature - four matching symbols arranged in a square merge to create a powerful symbol that doubles connected wins. Each winning cluster feeds energy to the mighty Gargantoon, patiently waiting to unleash his power.
Reactoonz boasts a player-friendly 96.51% RTP, ensuring fair returns during extended gaming sessions. The dynamic combination of cascading symbols and cluster mechanics creates endless possibilities for multiple wins, delivering an electrifying slot experience.
Understanding Reactoonz Symbols
The vibrant universe of Reactoonz features an enchanting collection of alien creatures, each bringing distinct payouts and special abilities to enhance gameplay excitement.

One-eyed Aliens Explained
Low-paying symbols take the form of one-eyed aliens, appearing in four unique variations. Round yellow and triangular green specimens deliver payouts ranging from 0.1x to 3x your bet. Square red and rhombus purple variants offer enhanced rewards, stretching from 0.15x to 10x your stake when forming clusters of 5 to 15+ matching symbols.
Two-eyed Aliens and Their Values
Premium symbols showcase majestic two-eyed aliens, distinguished by their prominent horns and dual visual organs. The blue creature rewards players with 0.5x to 75x their bet, while its orange counterpart delivers 0.6x to 150x payouts. Green aliens raise stakes further with 0.8x to 300x returns, yet pink aliens stand supreme, offering spectacular rewards up to 750x your stake for clusters of 15 or more.
Wild Symbols and Their Effects
Reactoonz takes a unique approach to wild symbols - rather than appearing naturally, these energetic vortexes manifest through specific game events. These powerful symbols substitute for any alien character, creating enhanced winning possibilities.
Wild symbols materialize through two primary methods:
- The Fluctuation feature generates two wilds when highlighted low-value symbols participate in winning combinations
- Gargantoon's influence randomly scatters 4 to 8 wilds across non-winning spins
Symbol interactions reach peak excitement when four matching aliens align in a square pattern, forming a Giantoonz. This powerful formation doubles all wins it contributes to, adding thrilling multiplier potential to every spin.
Core Game Features
The pulsating heart of Reactoonz beats through its Quantum Leap meter system. This innovative mechanism powers the game's most spectacular features, building excitement as winning combinations charge the meter with each spin.
Gargantoon Mechanics

The Gargantoon stands as Reactoonz's crowning achievement. This towering creature awakens after four quantum features fill the queue. His appearance triggers a spectacular three-act performance:
The show begins with a colossal 3x3 wild symbol commanding the grid. Each cascade splits this mighty wild into two 2x2 versions. The finale sees these splits multiply into nine separate wild symbols, creating a grid rich with winning potential.
Every spin starts with the random selection of a one-eyed alien as the fluctuating symbol. Winning combinations featuring this glowing creature spawn two wild symbols. The Instability feature might surprise players during non-winning spins, scattering four to eight wilds across the play area.
The Experiment Charger introduces additional excitement, activating special experiments after collecting 20 winning symbols. These scientific marvels include:
- Gamma Ray Burst: Unleashes 7-9 wilds that track cluster symbols
- Black Hole: Deploys 4-6 wilds with symbol-collecting powers
- Supernova: Releases 3-5 wilds that traverse the grid diagonally
Special Features and Bonuses

Quantum features represent the magical essence of Reactoonz, presenting players with four extraordinary power-ups that amplify winning possibilities. These features spring to life randomly as players fill the Quantum Leap meter through consecutive wins.
Implosion Feature
Marked by mesmerizing orange flames, the Implosion feature commands attention as it transforms three to six symbols into powerful Wilds. These newly formed Wilds unleash a chain reaction, obliterating adjacent symbols and welcoming fresh ones from above. Players witness spectacular winning sequences unfold across the grid during this cosmic event.
Demolition Feature
Blue flames herald the arrival of the Demolition feature, a force that seeks and destroys all one-eyed aliens and their matching symbols. Fresh aliens descend to occupy the vacant positions. Though subtle compared to its quantum counterparts, skilled players harness this feature to clear paths for premium symbol combinations.
Alteration Feature
Green flames signal the Alteration feature's mysterious power to select and transform one-eyed aliens into entirely new symbols. The feature displays remarkable adaptability - when one-eyed aliens are absent, it targets any available symbol. Premium symbol transformations often lead to unexpected winning clusters.
Incision Feature
Red flames announce the Incision feature's precise geometric assault on the grid. The sequence begins with a Wild symbol materializing in the grid's heart. Two diagonal lines then emerge, bearing identical randomly selected symbols. This calculated pattern creates winning possibilities as matching symbols align along the intersecting diagonals.
The quantum features require 25 winning symbols to charge. Once activated, they execute their powers in sequence, orchestrating potentially massive chain reactions. Strategic Wild placements and calculated symbol transformations combine with cascading mechanics to deliver substantial rewards.
