All Reactoonz Slots Explained

All Reactoonz Slots Explained

Although Energoonz was released back in December 2013, it wasn’t until Reactoonz arrived nearly four years later that the iconic Reactoonz slot series truly began. Since then, Play’n GO has expanded the universe with several innovative releases, making this interstellar collection one of the most popular Cluster Pays slot series ever created.

Below is a detailed overview of all Reactoonz slots, including gameplay mechanics, features, RTP, volatility, and maximum win potential.

1. Energoonz

Released in December 2013, Energoonz was Play’n GO’s first-ever grid-based Cluster Pays slot. The game is played on a 5x5 grid, with wins forming from clusters of three or more matching symbols.

Winning clusters trigger cascading reactions and increase the win multiplier, which can rise up to 10x. Clearing the entire grid rewards a payout of 1,000x your bet.

The Bonus feature activates when the word BONUS appears in one or more columns, offering up to 20 free spins and a 5x multiplier on a non-cascading grid.

With medium volatility, a 96.69% RTP, and a maximum win of 18,566x, Energoonz still holds the highest RTP in the series.

2. Reactoonz

Released in October 2017, Reactoonz is the most recognisable and widely played game in the series. It uses a 7x7 grid with Cluster Pays and features a dynamic Quantum Leap system.

Winning clusters trigger cascades and charge multiple Quantum Leap meters, unlocking powerful features such as:

Symbol destruction

Diagonal cluster wins

Wild transformations

Vortex Wilds

Filling all Quantum Leap meters activates the Gargantoon feature, introducing a large 3x3 wild, which splits into multiple wilds during cascades. Wins involving Giantoonz can also be doubled.

Reactoonz offers a 96.51% RTP, very high volatility, and a maximum win of 4,570x your bet.

3. Reactoonz 2

Reactoonz 2, released in October 2020, builds on the original formula while introducing new meters and interactions. The game is played on a 7x7 grid with Cluster Pays and cascading wins.

Key mechanics include:

Electric Wilds created by adjacent winning clusters

The Fluctometer, which adds up to three Electric Wilds

The Quantumeter, unlocking four charge levels

At higher charge levels, Energoon Wilds appear, including a 3x3 Gargantoon, and a 2x win multiplier for clusters involving Gargantoon Wilds. The Wild Pair Explosion feature can also remove symbols across rows or grids.

Reactoonz 2 has a 96.2% RTP and a maximum win of 5,083x, with high volatility.

4. Dr Toonz

Released in September 2021, Dr Toonz shifts away from Cluster Pays and instead uses Dynamic Payways, offering up to 262,144 ways to win across six reels.

Cascading wins charge the Quantumeter, triggering one of three features:

Adding up to six wilds

Transforming symbols

Removing symbols and replacing them with wilds

The Free Spins mode awards up to 25 spins, with pre-charged Quantumeters for frequent feature activation. Reel-based multipliers can stack up to 64x, significantly boosting payouts.

With high volatility, a 96.25% RTP, and a massive 22,000x max win, Dr Toonz is the highest-paying game in the Reactoonz series.

5. Gigantoonz

Launched in January 2022, Gigantoonz expands the grid to 8x8, introducing Mega Symbols that can grow up to 7x7 in size. Each winning Mega Symbol leaves behind a wild on the grid.

The Quantumeter charges through wins and activates features every 25 charges, including:

Symbol removal and transformation

Additional Mega Symbols

Quantum Wilds

Mega Gargantoonz upgrades

Gigantoonz features a 96.25% RTP, very high volatility, and a maximum win of 4,000x.

6. Gargantoonz

Released in November 2023, Gargantoonz returns to a 7x7 Cluster Pays grid and introduces fluctuating symbols and experimental mechanics.

Winning clusters charge the Experiment Charge, unlocking three experiments:

Gamma Ray Burst – removes symbols and adds wilds

Black Hole – wilds collect adjacent symbols

Supernova – roaming wilds collect symbols across the grid

Completing all experiments triggers the Gargantoonz feature, adding large 3x3 Gargantoon Wilds. Overcharged experiments increase a global win multiplier.

The game offers a 96.2% RTP, high volatility, and up to 7,000x max win potential.

7. Reactoonz 100

Released in October 2025, Reactoonz 100 is the most extreme entry in the series. Played on a 7x7 grid, it introduces an Energized Toon Multiplier that can reach an impressive 100x.

The Quantum Charger fills after landing 25 symbols, triggering four random features:

Implosion

Incision

Demolition

Alteration

The final Gargantoon upgrade creates merging wilds that culminate in a massive 3x3 wild. Additional mechanics include Instability Wilds and Fluctuation transformations.

Reactoonz 100 has very high volatility, a 96.2% RTP, and a maximum win of 10,000x.
