Play’n GO’s Reactoonz slot was a true hit when it came out. Its generous Cluster Pays system and the fun aliens across the grid made it a hit that’s still popular to this day. It spawned a sequel and a prequel, too, with the studio focusing on the cute aliens that occupy the grid. Gargantoon was the funniest and most rewarding of them all, and this alien species is the focus of the Gargantoonz slot.
It’s another Cluster Pays entry into the long-running franchise with high volatility and an RTP of 96.20%. While the gameplay is familiar, the slot has plenty of surprises on its own. The slot comes with plenty of galactic sci-fi features, including fluctuations, Quantum wilds, and other experiments. Charging and waking up Gargantoon is still the best way to hit the highest wins. While on the subject of wins, you can hit wins up to 7,000x the bet, which is more than the previous installments.
The Gargantoonz slot looks like a pretty great adventure on its own. Read our review below and see if it’s just as good as its predecessors.
Play’n GO has opted for a very familiar design with Gargantoonz. It has a 7x7 grid with a Cluster Pays system. It looks eerily similar to the Reactoonz slots, which isn’t a bad thing at all. Visually, the studio always delivers and doesn’t falter here either. The slot’s audio effects are suitable for an alien sci-fi theme.
The design is classic Play’n GO, meaning you shouldn’t have trouble playing the slot at all. All the controls are beneath the reels, so it’s easy to pick a bet and hit the Spin button to start playing.
Gargantoonz is fully mobile-optimized like the rest of Play’n GO’s lineup. You can give it a go for free and real money on Android and iOS devices. During our Gargantoonz slot review, we tried it on both systems, and it worked like a charm.
Before we started our alien world adventure, we needed to set a bet. The betting range goes from 10c to $100 per spin, so it’s suitable for all players. Once you set your bet, get ready – it’ll be a bumpy ride.
If you’ve played the previous Reactoonz real money slots, you already know the drill. A cluster of 5 symbols is required for a win, which triggers a cascade. Each pop removes the old winning symbols and fills the grid with new ones, eventually triggering a new cascade. The process will continue as long as you keep landing winning symbols.
There’s no free spins round in the Gargantoonz online slot, but it substitutes it with the familiar Gargantoon charge feature. Like in other Reactoonz slots, the Gargantoon sleeps while you fill up his charger. To wake him up and trigger the eponymous feature, you’ll have to finish all three experiments at once.
When that happens, eight 1x1 Gargantoon wilds will be added to the grid. They will then merge into two 2x2 wilds and then a single 3x3 Gargantoon wild. The whole process has 3 stages. On top of the massive wilds, you also get multipliers attached to them, which further boost your wins.
Like most Play’n GO slots, the RTP for this highly volatile slot is set at 96.2%. The maximum projected win in Gargantoonz is 7,000x the bet.
Gargantoonz is a fun slot to play that continues the familiar Play’n GO story. It has added some new experiments to the grid, which make things even more exciting. Wilds and Gargantoon wilds are in the focus, with most of the experiments revolving around them. If you’re a fan of the franchise and the largest character in them all, Gargantoonz is a must-try at our recommended casinos online.

Read Full BioThe Gargantoonz slot was developed and published by Play’n GO. It’s one of the biggest software developers on the market, known for hits such as Book of Dead and Legacy of Dead. Play’n GO is also behind the Reactoonz franchise that Gargantoonz fits in.
The RTP for the Gargantoonz slot is set to 96.20%. That will be a familiar figure to most Play’n GO fans. The majority of highly volatile slots in the developer’s portfolio have this RTP figure, and we have to say it suits the mechanics and math model well.
You can place bets as low as 10c in the Gargantoonz slot. That’s the average minimum bet in the industry nowadays. The bet selector tool beneath the reels goes up in small increments all the way up to $100 per spin, which is a figure high rollers will like.
No, it’s not. It’s a Cluster Pays slot machine that shares some features with Megaways titles. Most notably, it shares the cascades or avalanches triggered on every win. To start a cascade, you need 5 identical symbols in a cluster, with wilds helping complete wins.
The Quantum wilds come in many shapes and sizes. Most of the features revolve around adding Quantum wilds to the grid that can complete or improve wins. Besides the regular substitution feature, the Quantum wilds do nothing special and have no paytable.
The Gargantoonz feature is triggered by completing all three experiments at once. When that happens, the Gargantoon will wake up and possess the grid as eight 1x1 wilds. On the next spin, it’ll merge into two 2x2 Gargantoon wilds, then a single 3x3 Gargantoon wild that can create some truly great wins.
No, there’s no free spins bonus round in Gargantoonz. It’s been replaced with the Gargantoon feature, which is equally — if not more — rewarding than most free spins bonuses. It has three stages where the wilds shift and absorb everything around them for big wins.
The experiments are accessed by filling out the experiment changer meter. It needs 20 winning symbols to fill up, after which you get one of the three experiments. They all add Quantum wilds to the grid that can create major winning combinations and fill the Gargantoonz meter.
We don’t have a promo code for the Gargantoonz slot just yet. But there might be one to use in the future. Keep an eye on the promotions page. There’s bound to be a slot promo code later, and one might be available for this particular slot.
The Gargantoonz slot was released on November 30, 2023.
