Gigantoonz Slot Review: High Volatility Slot By Play’n GO

Some call them aliens, some monsters, but one thing is for sure: the protagonist of the Gigantoonz slot machine is the most colourful and fun that online slots have to offer! We’re up against a slot online game with an RTP of 96.25% and high volatility, among the most dynamic and fun out there.

Gigantoonz is part of a very popular series of slots, as it is the sequel to Reactoonz, another Play’n GO masterpiece. This slot features an 8×8 grid, with no paylines but with a Cluster Payout mode to unlock wins, with a maximum value of 4,000 times the amount staked.

Giant symbols, Quantum Wilds, and modifiers that destroy or alter the appearance of the reel icons are all elements of online slot machines that will amaze you with every spin. This Gigatoonz slot review will guide you to more wins!

How to play Gargantoonz slots

The Gargantoonz slot produced by Play’n GO has mechanics that are very easy to learn, although the gameplay is still varied. You can practice thanks to the play money mode, a demo version of our free slot, which can be used both on desktop and on major mobile devices, iOS and Android.

Below the box full of symbols is a panel with all the game controls. The first button, from right to left, is the button to set the auto-rotate. Next to it is a spin button, followed by buttons dedicated to various bet amounts. 

Finally, the “i” button allows you to access the information on the Gigantoonz slot machine. Next, here you will have access to the payout table, where you can first consult the basic symbol values:


  • Yellow, green, orange, purple and blue aliens
  • Blue, ocher, green, pink and red monsters

Gargantoonz Slot: Bonuses & Technical Features

Relax, because we have come to the most interesting part of the Gargantoonz slot feature. Let’s start with the Mega Symbols, which can appear in six different dimensions:

  1. 2×2
  2. 3×3
  3. 4×4
  4. 5×5
  5. 6×6

Each Mega Symbol takes a random value, which in combination can reach up to 13: this is a significant number because it will be the one that will weigh in the evaluation of the winning combination. Quantum Wilds, on the other hand, are wild symbols that also have a special function: they can actually appear, in 5 or 10 units, during a losing spin.

Quantum meters, on the other hand, are meters filled with “loading” with winning symbols. There are 4 charging levels and each activates a special Gargantoonz function: 

  1. Disintegration: choose 4 types of symbols and delete them all at random.
  2. Metamorphosis: choose one type of symbol and convert it to another symbol, including Mega Symbol.
  3. Radiation: adds 2 to 5 Quantum Wilds and 1 to 4 Mega Symbols to the reels.
  4. Gargantoonz: it is the final form of Quantumer, which first turns all Mega Symbols into this giant symbol, Mega Gargantoonz, which is then split into many smaller Gargantoonz.

We remind you that this game offers a maximum payout potential of 4,000 times the amount wagered on all the casino sites that feature these online slots.

Maximum Payout, RTP & Volatility

As we already mentioned, the return to player percentage (RTP) of the Gargantoonz slot is 96.25% – not too high, but not too low either. Volatility, on the other hand, is high: this means you should expect important wins, but also dry periods. On the other hand, there are no jackpots, neither regular nor progressive.

 Our Thoughts on Gargantoonz Slot

To conclude, the Gargantoonz slot online machine is a crunching game, with tons of functionality and features that make it awesome with every spin of the reels. Playing with it is simple, although it takes a while to understand all the features well. For this reason, we would like to recommend it to players who already have at least minimal experience on slot machine sites.

A simpler alternative to Gargantoonz slot, but always with Cluster Pays, is Aloha! NetEnt Cluster Paying. If you want to deviate from the alien theme, turning to cartoons, give Playtech’s Pink Panther a chance, which also has a progressive jackpot. Sticky wild fan? Then Riches of Ra from Play’n GO is your game!

All in all, thank you for reading this Gargatoonz slot review. Best of luck!
