Play’n GO launches 7×7 cascading grid slot Gargantoonz, the newest addition to the Reactoonz series


Swedish casino entertainment provider Play’n GO has unveiled the latest addition to its Reactoonz series with the introduction of a new grid slot called Gargantoonz.

The release marks the return to the sci-fi theme for the first time this year and the next chapter in the Reactoonz story. Following Gigantoonz (2022), the storyline unfolds with Dr. Toonz successfully creating a small one-eyed Gargantoon. The objective is to conduct experiments on the Gargantoon, aiming to integrate it into Reactoonz society and generate wealth.

Gargantoonz is a 7×7 cascading grid slot that features a deep blue backdrop, mimicking the dark space – counterbalanced with colorful Reactoonz character symbols. The player’s goal is to clear five or more alien-themed clusters to create a win.


In this game, Dr. Toonz has plenty of tests and trials up his sleeve, evolving the series further by introducing new ‘experiments’ including Gamma Rays, the Black Hole, and Supernova. Charging the meter to unlock each experiment, they add new ways to help the player win on the grid from additional wilds and increasing multipliers. The aim of the game is to evolve the small Gargantoon to his apex form seen in the prequels. 

The experiment-driven features in Gargantoonz intertwine with the slot’s overall story. As per the company, the latest addition to the popular IP continues to show the growth and innovation in grid slots that Play’n GO pioneered with their releases Energoonz and GEMiX.

Magnus Wallentin, Games Ambassador at Play’n GO, said: “We’re so happy that the Reactoonz series is back with more out-of-this-world features. It’s been a year since their last adventure, we pondered ways in which we could innovate the series – while still including all of the galactic features that make the series unique.

“That’s why we chose to include the Experiment Charger and bind Dr Toonz’s experimentation narrative to the grid slot features in Gargantoonz. When players use the Black Hole, Supernova and Gamma Ray features, it really puts them at the heart of the experiment.”
