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.

• To make things easier, the slot has added Quantum Wilds to the grid. They come in different designs and can substitute any symbol in a winning combination. At the start of each spin, the slot picks one of the low-paying symbols randomly – if you score a win that involves that particular symbol, 1-2 Quantum wilds are added to the grid.
• Losing spins can sometimes trigger the discharge feature. It adds 4-8 wilds to random positions, which can greatly improve your payouts.
• Look to the left – there’s a progress bar named Experiment Charger. All winning clusters contribute to it. Fill it up with 20 symbols, and one of the game’s experiments will be triggered. The experiments include Gamma Ray Burst, which adds 7-9 wilds; Black Holes, which add 4-6 wilds and collect other symbols; and Supernova, which adds 3-5 wilds to the grid, which collects even more symbols to fill the meter.

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.
