Reactoonz Theme, Design & Sound

Theme and Design

Reactoonz takes players on a journey through an alien-infested world, with cute and colorful extraterrestrial creatures dominating the game’s 7×7 grid. The vibrant graphics and smooth animations create an immersive gaming experience that’s sure to captivate players.

Sound Experience

Reactoonz features an upbeat, electronic soundtrack that perfectly complements the game’s alien theme. The sound effects, such as the satisfying jingles when a winning combination lands, add to the overall gaming experience without being too overwhelming.

Slot Mechanics & Gameplay

Basic Gameplay

Cluster Pays

Reactoonz uses a cluster pays mechanic, which means that winning combinations are formed by landing five or more matching symbols in a connected cluster, either horizontally or vertically. This unique system adds an exciting twist to the traditional payline structure.

Cascading Reels

When a winning combination is formed, the winning symbols are removed from the grid, and new symbols cascade down to fill the empty spaces. This can potentially lead to multiple consecutive wins from a single spin, keeping the excitement levels high.

Betting Options

Players can wager between $0.20 and $100 per spin, catering to a wide range of budgets. Whether you’re a casual player or a high roller, Reactoonz has a betting option that suits your preferences.

Autoplay Function

For those who prefer a more hands-off approach, Reactoonz offers an autoplay function. You can set the game to automatically spin for a predetermined number of rounds, allowing you to sit back and watch the action unfold.

Paytable & Symbols

Regular Symbols

One-Eyed Aliens (Low-Paying)

The lower-paying symbols in Reactoonz are represented by cute, one-eyed aliens in various colors. While these symbols may not offer the biggest payouts, they still contribute to the game’s overall charm and theme.

Two-Eyed Aliens with Horns (High-Paying)

The higher-paying symbols in the game are depicted by two-eyed aliens with horns, also in different colors. Landing a cluster of these symbols can lead to some impressive payouts, especially when combined with the game’s bonus features.

Special Symbols

Wild (Vortex)

The wild symbol in Reactoonz is represented by a swirling vortex. This symbol can substitute for any other symbol, helping players form winning clusters more easily.

Fluctuating Symbol

In each spin, one random one-eyed alien symbol is chosen as the fluctuating symbol. If this symbol is part of a winning combination, it will leave two wild symbols behind, increasing the chances of creating additional winning clusters.

Reactoonz Special Features

Quantum Leap

The Quantum Leap feature is at the heart of the action in Reactoonz. Each time you land a winning combination, the Quantum Leap charge meter fills up. Once the meter is fully charged, one of four unique Quantum features is triggered, adding an extra layer of excitement to the gameplay.


The Implosion feature transforms 3 to 6 symbols into wilds while also destroying adjacent symbols, potentially leading to even more winning clusters.


When the Alteration feature is triggered, one randomly chosen one-eyed symbol transforms into another symbol, increasing the chances of forming winning combinations.


The Demolition feature destroys all one-eyed symbols on the grid, making way for new symbols to cascade down and potentially create new winning clusters.


During the Incision feature, a wild symbol is placed in the center of the grid, and two diagonal lines of the same symbol intersect through the wild, potentially leading to multiple winning combinations.


The Gargantoon feature is the ultimate goal in Reactoonz. When you fully charge the Quantum Leap meter five times, the Gargantoon feature is triggered. A colossal 3×3 wild symbol appears on the grid, which can lead to massive wins. With each subsequent cascade, the Gargantoon wild splits into smaller 2×2 and 1×1 wilds, increasing the chances of forming even more winning clusters.

Quantum Features

Instability Feature

On any non-winning spin, there’s a chance that the Instability feature will be triggered. During this feature, 4 to 8 wild symbols are randomly added to the grid, potentially leading to unexpected wins.

Giantoonz Feature

When four matching symbols land in a square formation, they merge to create a Giantoonz symbol. Any winning combination that includes a Giantoonz symbol will have its payout doubled, significantly boosting your winnings.

RTP, Volatility & Max Win Potential

RTP Variations

Reactoonz offers a competitive Return to Player (RTP) percentage of 96.51%.

The maximum win potential in Reactoonz is an impressive 4,750x your bet. This significant top prize is made possible by the game’s various bonus features, particularly the Gargantoon wild and the Quantum Leap features.
