Reactoonz by Play’n GO has a 7-reel, 7-row appearance with high volatility and an RTP of 96.52%. This electrifying game has the avalanche feature, a charge meter, and cluster pays mechanics, which allows for wins to form in clusters and can lead to bigger payouts the larger your cluster. With the game’s special bonus games and features, Reactoonz can lead players to a maximum win of up to 4570x the stake.
Paytable & Paylines
Meet these quirky little aliens in this thrilling space adventure that can lead to massive wins! Designed with a dynamic and interactive grid, the game explores this new universe as you navigate your way through space and earn big rewards with some help from these friendly animated life forms.
The symbols are the Reactoonz aliens themselves, each with a corresponding payout. The low-value symbols are the low yellow toon, low green toon, low red toon, and low purple toon, which can pay from 0.1x to 0.15x. The high-value symbols are the high blue toon, high yellow toon, high green toon, and high purple toon, which can pay from 0.5x to 1x, with the high purple toon being the most valuable.
Regarding paylines, the game is powered by the cluster pays mechanics, allowing wins to form when 5 or more symbols match horizontally or vertically, forming clusters and leading to bigger payouts with every win. Reactoonz has special symbols and bonus games called ‘quantum features‘ that can lead players to up to 4570x their bets.

Game Features
Play’n GO integrated a lot of exciting bonus features into this quirky slot. The animated aliens on the reels drop from space and land to occupy the reels, and with the avalanche feature, winning symbols disappear and make space for new symbols to drop and form more wins. This, along with its bonus games, is what makes the game engaging and electrifying.
One of the most distinctive elements of “Reactoonz” is the Quantum Leap Charge Meter. Players fill up this meter by forming winning combinations of the alien symbols. For each winning cluster, a portion of the meter fills up. Once the meter is fully charged, it triggers one of the Quantum features, adding a unique dynamic to the game.
The four Quantum features are:
- Implosion: Transforms a set number of symbols into wilds while also destroying adjacent symbols, creating space for new symbols to drop.
- Alteration: Chooses one random low-value symbol, and all matching symbols are transformed into another symbol, potentially creating new winning combinations.
- Demolition: Removes all low-value symbols from the grid, allowing new symbols to cascade down.
- Incision: Cuts a wild symbol into the center and creates two intersecting diagonal lines through the grid. All symbols along these lines are transformed into matching symbols.
The Gargantoon is a large, friendly alien leader of the pack that sits just beside the reels. When players charge up the Quantum Leap meter to the maximum level, the Gargantoon feature is triggered. The Gargantoon initially adds a 3×3 wild symbol to the grid, which can lead to significant wins. In subsequent cascades, the Gargantoon divides and moves, first turning into two 2×2 wild symbols and, finally, into nine 1×1 wild symbols.
Reactoonz also has two more features called Giantoonz and Fluctuation. When four matching symbols appear in a 2×2 square, they form a Giantoonz. Wins involving these larger symbols are doubled, increasing the potential payout.
Fluctuation, on the other hand, is when one low-paying symbol is randomly marked as a fluctuating symbol. If it forms part of a winning combination, it leaves two wild symbols behind on the grid, enhancing the chance of forming additional winning combinations.
These features are what make this game a solid favorite among players since its release in 2017. Reactoonz is packed with bonuses that can lead players to wins that are up to 4570x the stake while delivering a dynamic gaming experience.
