Play at Casiku Casino
Reactoonz 100, developed by Play’n GO, is the latest instalment in the popular Reactoonz series, due for release on 23 October 2025. This new entry in the long-running series builds on the chaos and quirky alien energy that’s kept the franchise spinning since 2017. The grid pulses with colour and features the familiar character Gargantoon and his cartoon crew of lovable aliens, with a 100x twist baked into every cascade.
Played on a 7×7 grid and utilising the signature cluster pays system, Reactoonz 100 boasts excellent animations, slick chain reactions, and stacking features that transform straightforward cascades into a full-blown alien storm. With an RTP of 96.20%, high volatility, and a max win of 20,000x the bet, it’s set to become the most charged Reactoonz release yet.
Technical Features
Reactoonz 100 has a 7×7 grid and utilises the Cluster Pays mechanic. It’s highly volatile with an RTP of 96.20% and a max win capped at 20,000x the bet. It’s available on desktop and mobile devices, ranging from 20p to £100 per spin, making it suitable for all budgets. Each cascade charges the Quantumeter, unlocking the chaos that defines this series.
Design & Symbols
Reactoonz 100 takes place in a distant corner of space, surrounded by drifting planets, shattered asteroids, and a backdrop that glows with movement. The grid sits in the middle of the screen, framed by a satellite tracking your current multiplier to the left and Gargantoon inside his glass chamber on the right, waiting for the next surge of power. The slot is colourful and bright, with the familiar Toons muttering across an ambient soundtrack.
The low-paying symbols are the green, red, yellow, and purple one-eyed Reactoonz, awarding 1.5x to 2x the bet for clusters of 15 or more. The high-value symbols are green, blue, orange, and purple two-eyed Toons, awarding 10x to 100x the bet for the 16+ matching symbols. The Wild symbol, represented by a black hole, substitutes for standard symbols to help form winning clusters.
Features Overview
Reactoonz 100 revives the signature chain reactions that drive the series, powered through the Quantumeter beside the grid. Each cluster win charges the meter, unlocking one of four Quantum Features: Implosion, Incision, Demolition, or Alteration.
Random Instability events drop additional Wilds after non-winning spins, while Fluctuation highlights one symbol type per round and transforms it into Wilds when part of a winning combo. When the Quantumeter is fully charged, Gargantoon awakens and lands on the grid as a giant Wild that divides and multiplies through successive cascades.
Cascades
Every time a winning cluster lands, the symbols involved disappear, allowing new symbols to fill the empty spaces. The new symbols can form new winning clusters, resulting in multiple wins on a single spin. Each successful cascade charges the Quantumeter. The process continues until no new clusters appear.
Energized Toons & Multipliers
Each winning cluster charges the grid and feeds into the global multiplier. Wins featuring one-eyed Reactoonz increase the multiplier by 1x, while clusters of two-eyed Reactoonz boost it by 3x. The multiplier can reach 100x, influencing every payout along the way.
During each cascade, a random symbol is chosen as an Energized Toon, carrying the current multiplier. Any cluster that includes this symbol has the current multiplier applied to the win.
Quantum Charger
Every winning cluster contributes energy to the Quantum Charger, unlocking a chain of modifiers. Collect 25 or more symbols within a set of cascades to trigger one of five Quantum Features. Four of them appear in random order, while Gargantoon is the last to trigger.
⭐ Implosion – Transforms between three and six symbols into Wilds, destroying all adjacent symbols.
⚡ Incision – Splits a Wild through the centre of the grid, forming two diagonal lines filled with matching symbols.
Demolition – Removes all one-eyed Reactoonz along with one random symbol type.
Alteration – Selects a random one-eyed symbol and transforms all matching symbols into another type.
Gargantoon – Drops eight Wilds onto the grid. The Wilds expand to 2×2 and then 3×3.
Instability
After every non-winning spin, there’s a chance the Instability feature will trigger. When it does, between four and eight Wild symbols drop into random positions on the grid, instantly opening new opportunities for clusters to form.
Fluctuation
At the beginning of each spin, a one-eyed Reactoonz symbol is randomly highlighted. If a winning cluster includes the highlighted symbol, it creates two Wild symbols once the cluster is removed.
Verdict
Reactoonz 100 proves that a great series can evolve without losing its identity. Play’n GO have resisted the temptation to redesign the concept; instead, they have refined it with progression and more deliberate pacing. Every element, from cascading clusters to Quantum Features, builds momentum and progression rather than relying on luck.
Free spins are unnecessary here. The rotation of modifiers, Wild surges, and increasing multipliers holds the momentum, leading towards that defining 100x multiplier. With a 96.20% RTP, high volatility, and a maximum win of 20,000x, it’s designed for those who value rhythm, control, and steady pacing. Reactoonz 100 is a confident continuation; it’s precise, purposeful, and every bit as engaging as the original.
