Gargantoonz Slot Review & Free Demo (Play’n GO)
Play’n GO bring back those wonderfully weird little aliens from the Toonz universe for another wild romp through space. This 7×7 grid slots with cluster pays is a real doozy with an RTP of 96.20%, high volatility that’ll push your nerves to the limit and wins that can rocket up to 7,000x your bet – not too shabby for a day of Dr Toonz’s bizarre experiments in his lab.
Gargantoonz Theme & Design
You’re straight away dropped into the high-tech laboratory of Dr Toonz, where alien experiments are just getting a bit… well, out of hand. The whole thing’s got that zany Toonz vibe that fans of Reactoonz, Reactoonz 2 and Gigantoonz are so used to – cartoonish aliens, bright colours, and the odd energetic blast will make you think you’ve just knocked over a can of Red Bull all over your keyboard.
On the visuals front, the colours really pop, and the characters have a whole lot of personality. The soundtrack’s a cheesy 80s sci-fi synth that’s sure to get stuck in your head after a few spins – like the soundtrack to your brain after a few too many spins.
RTP, Volatility & Max Win
Don’t mess about – with an RTP of 96.20% and high volatility, Gargantoonz is a slot that’s best suited to players who enjoy the odd dry spell in the hopes of hitting something big. And big it is too – the top payout is a whopping 7,000x your bet.

How It Works
No paylines here, just cluster wins. Get five or more matching symbols that are connected horizontally or vertically, and then, bang, you’ve won. The winning clusters then blow, new symbols drop in, and by the luck of the draw, you might just get a cascading chain of wins going.

Symbols & Payouts
Low-paying symbols are the one-eyed aliens in a range of colours, and the high-paying symbols are the two-eyed ones, with the red one paying out the most. The wild symbol is a glowing orb that drops in to help with winning clusters.
Gargantoonz Special Features
Fluctuation
Each spin randomly selects one of the one-eyed aliens to “fluctuate” – if you win with it, you get a pair of Wilds that drop in where it used to be – like a mini-win explosion.
Discharge
If a spin doesn’t produce a win, Discharge kicks in and randomly slaps the grid with 4 to 8 Wilds – like the slot gods nudging you along.
Experiment Charger
Winning clusters fill up the Experiment Meter – fill it and you get to choose from some wacky lab experiments – Gamma Ray Burst, Black Hole, or Supernova. Each one will turn the grid into a wild, wonky place with new Wilds and all sorts of extra chances to win.

Gamma Ray Burst
Adds 7-9 Wilds to the grid, then counts all the clusters – all before blasting off.
Black Hole
Creates a mess of 4-6 Wilds that stick around until no more wins. They then suck in any nearby symbols and charge the Experiment Meter again.
Supernova
Unleashes a blast of 3-5 Wilds that move diagonally after each cascade, snatching up any symbols in their path – complete chaos, but the good kind.
The Gargantoonz Feature
Exactly when the lab loses its mind – complete all the experiments, fill up the meter and out comes the Gargantoonz.
These massive Wilds come in three giant sizes: 1×1, 2×2, and 3×3.
Each size gets a bigger multiplier – by the time you get to the 3×3 version, it’s like watching an alien baby go supernova, unpredictable, loud and might turn your wallet into a pile of space dust.

Final Thoughts
Gargantoonz is no ordinary slot – it’s like a wild, rudderless ship careening through space – clusters blow up, Wilds multiply, and aliens with too much caffeine create a chaotic mess. If you enjoy riding the high-volatility rollercoaster and don’t mind a few dead spins for the sake of a massive win, then this may be the game for you.
