Base game with Gargantoon on the right of the reels.
Base Game

Reactoonz is a video slot with a 7×7 grid and cluster pays. Wins hit when you land 5 or more symbols connected horizontally or vertically. Bet sizes range from a min of 0.20 to a max of 100. The standard RTP is 96.51%, but watch out – operators can tweak it down to 94.51%, 91.49%, 87.50%, or even 84.51%. Expect high volatility here, with a max win capped at 4570x your bet.

Reactoonz Slot Info

The Reactoonz screen is packed with techy stuff around the grid, floating against a dark blue space background. You’ve got a whole army of 49 creatures on the grid. Don’t picture scary monsters though – these guys are pretty friendly and helpful.

On the right, Gargantoon chills in his capsule, and above him, the Quantum Leap meter is waiting for energy to fire up. On the other side, there’s a counter showing your wins as they land during a spin.

The vibe is super lively thanks to tons of unique symbol animations, even when you’re not spinning. The audio-visuals really kick in when clusters form and features trigger. You need at least 5 matching symbols connected to score a win. Game runs smooth on most mobiles and desktops.

Low-paying symbols are the one-eyed aliens. You’ve got a yellow circle, green triangle, red square, and purple diamond. They pay from 3x to 10x your stake for 15+ in a cluster. High-paying symbols are four two-eyed aliens: blue, orange, green, and pink. These pay from 75x to 750x your stake for clusters of 15 or more. Wild symbols are swirling energy balls, but they only drop through the Fluctuation and Quantum Features.

Reactoonz Slot Features

What’s the max win on Reactoonz?

Top prize is 4570x your bet.

What features are in Reactoonz slot?

Features include: Cascades, Wilds, Instability, Quantum Leap, Implosion, Incision, Demolition, Alteration, Giantoonz, Fluctuation, and Gargantoon.

Quantum Leap Demolition feature activation.

Demolition — Quantum Leap

Cascades

Winning clusters vanish, triggering a cascade. Remaining symbols drop down, and new ones fill the gaps, creating chances for more wins. Cascades keep going until no new clusters form.

Instability

On a non-winning spin, this feature can randomly pop, adding 4 to 8 Wild symbols onto the grid.

Quantum Leap

Each winning cluster charges the Quantum meter with points equal to the number of symbols in the cluster. Every 25 units fills a charge, activating a feature and adding it to the queue. Features trigger one by one after the cascade sequence ends. Four different modifiers can fire:

Implosion

Transforms 3 to 6 symbols into Wilds and nukes all adjacent symbols.

Incision

Slaps a Wild in the center and carves out two intersecting diagonal lines, filling them with matching symbols.

Demolition

Wipes out all low-paying one-eyed alien symbols, triggering a cascade for potential wins.

Alteration

Morphs all instances of a randomly picked one-eyed symbol into another symbol.

Giantoonz

When 4 identical aliens form a 2×2 square, they merge into a Giantoonz. Any win with this symbol gets a 2x multiplier.

Instability feature activation adding six wild symbols to the reels.

Instability

Fluctuation

At the start of each spin, one low-pay symbol is highlighted as fluctuating. Highlighted symbols in a winning cluster leave behind 2 Wild symbols.

Gargantoon

When the Quantum meter hits its fifth charge, Gargantoon comes alive and crashes onto the grid. He’s a 3×3 Wild symbol that lands in a random spot. After the first set of wins, he splits into two 2×2 Wild symbols. On the next cascade, his final form kicks in, breaking down into 9 individual Wild symbols.

F.A.Q.

What is Reactoonz slot about?

Reactoonz is a vibrant and engaging online slot game set in a whimsical space world filled with quirky, friendly alien creatures. The central character is Gargantoon, a large and powerful alien who oversees the gameplay and triggers exciting bonus features. The game is played on a 7x7 grid and utilizes a cluster pays system, where wins are achieved by forming groups of five or more matching alien symbols. Reactoonz is known for its dynamic gameplay, featuring cascading reels, a variety of bonus features triggered by the Quantum Leap meter, and the potential for substantial payouts up to 4570 times your initial bet. It's a high-volatility slot designed for players who enjoy fast-paced action and the thrill of chasing big wins amidst a visually appealing and entertaining alien adventure. Prepare for a cosmic journey packed with unique features and energetic animations that keep the gameplay fresh and captivating.

How do you achieve wins in Reactoonz?

In Reactoonz, winning combinations are formed by landing clusters of five or more identical symbols that are connected either horizontally or vertically on the 7x7 grid. This means there are no traditional paylines; instead, you aim to create groups of matching alien symbols. When a winning cluster is formed, the symbols involved vanish from the grid, and a cascade mechanism is activated. This allows the remaining symbols to drop down into the empty spaces, and new symbols fall from above to fill the grid. This cascading effect can lead to consecutive wins from a single spin if new clusters are formed after the initial win. The game continues to cascade until no new winning clusters are created, maximizing your potential for multiple payouts within one game round. The larger the cluster, the greater the win, and the more energy is charged into the Quantum Leap meter, leading to bonus features.

What are the key bonus features in Reactoonz slot?

Reactoonz boasts a rich array of bonus features that significantly enhance the gameplay experience. The core feature is the Quantum Leap, which is charged by winning clusters. Each cluster contributes energy to the meter, and filling it triggers one of four Quantum features: Implosion, Incision, Demolition, and Alteration, each offering unique ways to boost your wins. Additionally, the Instability feature can randomly activate on non-winning spins, adding Wild symbols to the grid. Giantoonz are formed when 2x2 squares of identical aliens appear, doubling wins they contribute to. The Fluctuation feature highlights low-paying symbols, which can leave behind Wilds when part of a winning cluster. Finally, when the Quantum Leap meter is charged five times, the Gargantoon feature is activated, introducing a massive 3x3 Wild symbol that evolves through cascades, splitting into smaller Wilds to maximize winning potential. These features combine to create a highly dynamic and engaging slot experience.

What is the RTP and Volatility of Reactoonz slot?

Reactoonz has a standard Return to Player (RTP) rate of 96.51%, which indicates the theoretical percentage of wagered money that players can expect to win back over an extended period of gameplay. However, it's crucial to note that operators have the flexibility to adjust the RTP, and you might encounter versions with lower RTPs of 94.51%, 91.49%, 87.50%, or even 84.51%. Therefore, it is always advisable to check the RTP at your chosen casino before playing. In terms of volatility, Reactoonz is classified as a high volatility slot. This means that wins may not occur as frequently compared to low or medium volatility slots, but when they do hit, they have the potential to be significantly larger. High volatility slots are suited for players who are comfortable with periods of less frequent wins in pursuit of bigger payouts and more thrilling, high-risk gameplay. The maximum win in Reactoonz is capped at 4570 times your bet, reflecting its high volatility nature.

Who is Gargantoon and how does the Gargantoon feature work?

Gargantoon is the prominent, larger alien character featured in Reactoonz, often seen floating in a capsule to the right of the game grid. He is central to one of the most exciting bonus features in the slot, the Gargantoon feature. This feature is triggered when the Quantum Leap meter is fully charged for the fifth time. Once activated, Gargantoon dramatically descends onto the grid as a massive 3x3 Wild symbol, substituting for other symbols to create winning clusters. After the initial cascade sequence with the 3x3 Gargantoon, he doesn't disappear immediately. Instead, he splits into two 2x2 Wild symbols for the next cascade, increasing the chances of further wins. Finally, on the subsequent cascade, these 2x2 Gargantoon Wilds further break down into nine individual 1x1 Wild symbols. This three-stage transformation of Gargantoon Wilds across consecutive cascades provides multiple opportunities for significant wins and adds a dynamic and engaging element to the gameplay.

Besides the Quantum Leap and Gargantoon, are there other features in Reactoonz?

Yes, beyond the Quantum Leap and Gargantoon features, Reactoonz includes several other exciting mechanics to enhance gameplay. The Instability feature can randomly trigger on any non-winning spin, adding between 4 to 8 Wild symbols to the grid in random positions, potentially turning a losing spin into a winning one. The Giantoonz feature comes into play when four identical alien symbols form a 2x2 square on the grid. These Giantoonz act as larger symbols and, crucially, apply a 2x multiplier to any win they are part of, boosting payouts. Another feature is Fluctuation, where a low-paying symbol is highlighted at the start of each spin. If these highlighted symbols are part of a winning cluster, they leave behind two Wild symbols in their place, further increasing your chances of forming new winning combinations during the cascade sequence. These additional features, alongside the core Quantum Leap mechanics, ensure a constantly engaging and feature-rich slot experience.
