Gigantoonz™ by Play’n GO is a video slot that launches players straight into a space laboratory! Mutant extraterrestrial creatures merge and grow until they completely fill the grid, triggering explosive wins.
Released by Play’n GO on January 27, 2022, Gigantoonz™ is much more than just another online slot. It’s an interactive cosmic adventure. The action takes place in an intergalactic lab, where the laws of physics are replaced by wacky experiments with mutant aliens and explosive clusters.
The 8x8 grid, much larger than traditional formats, is packed with multicolored creatures that crash into each other, merge, and explode in cascading reactions! The starry purple background, quantum lightning bolts, and floating UFOs add a cinematic dimension to the game.
The soundscape amplifies this controlled chaos: electronic bloops, galactic zaps, and extraterrestrial giggles punctuate each session. You’ll recognize the Play’n GO sound signature that first appeared in Energoonz™ (2014), the game that laid the groundwork for this electric laboratory universe.
At the heart of the game is a legendary figure: the miniature Gargantoonz.
Sitting to the right of the grid, crowned and mischievous, he watches the game unfold with a knowing grin. His role is central: he collects winning symbols through a progress bar once you collect 25 symbols, his special power is unleashed.
In Reactoonz™ (2017), the Gargantoon appeared as a 3x3 surprise event. In Reactoonz 2™ (2020), he would show up at the end of a charge to shake up the grid.
In Gigantoonz™, the Gargantoon is present from the very first spin! He’s a constant companion, adding tension and excitement to every moment of the game.
This permanent presence creates a bond with the player: each win isn’t just an amount added to your balance it’s a step closer to the game’s cosmic climax.
Gigantoonz™ uses a Cluster Pays system: connect at least 6 identical symbols to trigger a win. The symbols then disappear in an interstellar cascade, making room for new Toonz to fall onto the grid.
Main features:
Colossal Symbol & Mega Symbol
Aliens can merge into giant blocks of 2x2, 3x3, or even 4x4 squares, increasing your chances of massive payouts.
Quantum Leap (Quantum Meter)
Each win charges the Quantum Meter on the left of the grid. Once full, it triggers random effects:
Symbol removal
Transformation of Toonz into Wilds
Random multipliers
Collect Symbol & Gargantoonz
Each collected symbol feeds the mini Gargantoonz, visible at all times. When you reach 25 symbols, his special power is unleashed.
Dynamic Payways
Even though the game technically has one line, the clusters let you win in all directions, horizontally and vertically.
Cascading Reels
Wins trigger chain reactions, continuing automatically without any extra cost until there are no more clusters.
I’m Adrien, a passionate writer and casino game expert. For Kynox Casino, I tested Gigantoonz™ in depth, and I can tell you this: this game is unlike anything else.
From the very first spins, I felt that familiar rush of excitement that comes with cluster slots but here, it’s taken to another level. When the giant symbols started appearing, forming 3x3, then 4x4 blocks, I knew I was facing something different.
There was a key moment: a cascade that lasted longer than expected, the mini Gargantoonz flashing wildly, the grid overflowing with Mega Symbols… That kind of moment gives you real chills, even if the final win isn’t massive. It’s the visual and sound spectacle that creates the thrill not just the reward.
If you love immersive slots with a chaotic and unpredictable twist, then Gigantoonz™ is made for you!
