Gargantoonz Review

Not everyone likes aliens, but the ones that made it to the playing field in the Reactoonz-games are loved by many. Gargantoonz is a brand new online pokie from game developer Play’n Go and a new adventure in the popular Garga range. In  the recently launched Gargantoonz, you also get a new way of unloading modifiers which form the basis for all the magic that is performed by the Gargantoonz aliens. This isn’t the first ‘toonz’-pokie as Gargantoonz comes after Reactoonz (2017), Reactoonz 2 (2020), Dr Toonz (2021), and Gigantoonz (2022). All of these instalments turned out to be highly popular amongst players and the question is whether Gargantoonz can leave a lasting impression as well. We tried out the game and are more than happy to share our findings.

Review Gargantoonz

Players familiar with Play’n Go now will also be familiar with Reactoonz which is why we expect that Kiwis reading this review will feel comfortable from the very beginning. If you’re new to online gambling, you’ll most likely agree that these aliens are quite cute and hilarious at the same time. Play’n Go are known for their popular games although they have a lot of games that are the result of following the path of least resistance. We agree that providers don’t need to reinvent the wheel each time to be successful, and Gargantoonz will probably be another example of a game that will be added to a lot of lobbies. We believe that the name of this series will draw the attention of players whilst the 7 bonus features add a few extra reasons to try out this game.

How to Play

Play’n Go is one of the most experienced providers out there which explains the popularity of this game developer. Online casinos around the world have added this provider to their lobby so it should be a piece of cake locating this game. Always check first whether the casino of choice works with Play’n Go and make sure to try out the demo. In order to fully prepare yourself, here is how to play Gargantoonz.

  • Choose one of recommended Play’n Go online casinos in New Zealand. These casinos work with Play’n Go and are available for players in New Zealand.
  • Join the casino, and claim the welcome offer or one of the many casino bonuses. Most casinos work with bonus packages.
  • Look up Gargantoonz and try the demo version first.
  • Set a bet and think of your bankroll when doing so.
  • Hit the spin button and make your first spin.
  • Play responsibly and enjoy the ride.

Symbol Wins

The visuals in Gargantoonz meet our expectations which isn’t a surprise as there have been so many other games in this series. The playing field is well taken care of and is filled with high quality graphics whilst the same is true for the audio effects. We specifically enjoyed the Experiment Charger feature, both from a visual point of view and the thrills that come with it. As for the reels, there are both low value and high value symbols. The first group is recognised by the one-eyed aliens. The high value symbols are the aliens with 2 eyes with the Blocktoon symbol being the most valuable one as it pays out 1,500x the bet for clusters of 5 to 18+ in a cluster. Gargantoonz doesn’t work with a scatter, but other than that there are 5 wild symbols that have the function to substitute for all symbols. Here is more about the different bonus features in the game:

Symbol Payout
Unitoon 5 to 18+ = 0.1 to 20x the bet
Quantoon 5 to 18+ = 0.1 to 20x the bet
Buntoon 5 to 18+ = 0.2 to 40x the bet
Gemtoon 5 to 18+ = 0.2 to 40x the bet
Pentoon 5 to 18+ = 0.2 to 40x the bet
Glowtoon 5 to 18+ = 0.5 to 250x the bet
Tritoon 5 to 18+ = 0.5 to 250x the bet
Spiketoon 5 to 18+ = 0.6 to 400x the bet
Wacktoon 5 to 18+ = 0.8 to 500x the bet
Blocktoon 5 to 18+ = 1 to 1,500x the bet
Quantum Wild Substitutes for all symbols
Gargantoon Wild Substitutes for all symbols
Black Hole Wild Substitutes for all symbols
Supernova Wild Substitutes for all symbols
Gamma Ray Wild Substitutes for all symbols

Bonus Features

With an impressive number of 7 bonus features in the Gargantoonz pokie game, there is a lot to look forward to in this casino game. We invite you to read on as we explain the features in detail so that you can fully understand where your focus should be.

Fluctuation Feature

The Fluctuation Feature takes place on every spin. During each round, a one-eyed symbol is randomly picked as the fluctuating symbol. If it wins, 1 or 2 Quantum Wilds will land on the position where a symbol was removed.

Discharge Feature

A total of 4 to 8 Quantum Wilds can be added randomly to the playing field. This can happen on any spin in case of no winning combinations.

Experiment Charger

Winning clusters will charge the charger when there are no experiments with 20 symbols moved forward to fill the charger. When they succeed, an experiment is picked. If that experiment turns out to be successful, another experiment will unroll. If not, the experiment cycle comes to an end. At the beginning of the experiment, unique wilds are added to the playing field and all wilds will turn into the same wild. If an experiment is in progress, the wild symbols will return to the experiment charger with their symbol values. In this case, 40 symbols will fully charge the charger in this state. Then you will show how 40 extra symbols will overcharge the charger and add a +1 Gargantoonz multiplier.


There are different experiments that have their own characteristics. Here is more about the different types of experiments:

Gamma Ray Burst

During the Gamma Ray Burst, between 7 and 9 wilds are added to the playing field. In this case, winning wilds count the number of symbols in their clusters after all instances of the same symbols are removed and counted. Extra symbols that are removed are only counted once even if there are multiple winning clusters with the same symbol type. When all symbols are counted, the wilds will get removed from the playing field. In this case, the experiment charger will charge before any cascades take place.

Black Hole

During the Black Hole, between 4 and 6 wilds are added to the playing field. Winning wilds count the symbols in their clusters and remain on the playing field until wins take place. When cascades are completed, wilds collect adjacent symbols. This is done both vertically and diagonally whilst leaving the grid to charge the experiment charger. The removed symbols are then counted only once. If 3+ wilds are in the same cluster, they trigger the effect straight away, leaving the grid and charging the experiment charger.


During Supernova, between 3 and 5 wilds are added to the playing field. During this bonus feature, wilds count the symbols in their clusters, remain on the grid if there are wins, and step one position diagonally on each new cascade if that’s possible. When all winning cascades are complete, wilds will be removed 8 steps in any possible direction, collect symbols in their path and leave to charge the experiment charger. If 3+ wilds are in the same cluster, they trigger their effect straight away, leaving the grid and charging the experiment charger instead of remaining on the grid.

Gargantoon Charger

Every experiment that is successful will charge the Gargantoon charger and will make the Gargantoon evolve. The charger starts with a multiplier of 1x that is relevant only to the Gargantoonz feature, and each overcharged experiment adds 1x, 2x, 3x or 4x to that multiplier. If all 3 experiments are successfully completed, the Gargantoonz feature is activated.

Gargantoon Feature

This bonus feature takes place in 3 different steps. Here’s what we mean with that:

  1. Eight 1×1 Gargantoon Wilds land on the reels and remain to merge even if they take part in any wins.
  2. The 1×1 Gargantoon Wilds merge into 2 2×2 Gargantoon Wilds after wins are counted but before the next cascade. These also remain to merge on the reels after wins.
  3. The 2×2 Gargantoon Wilds is merged into a 3×3 Gargantoon Wild after wins are counted, before the next cascade. This 3×3 wild is removed when wins take place.

Each Gargantoon appears with the appropriate multiplier but only a single multiplier is applied to wins if there are more Gargantoon Wilds in a cluster.

Payout Metrics

The RTP of Gargantoonz is 96.2%, which is about standard for pokies by Play’n Go. Please note that there are different RTP’s as well that go down to 94.20%, 91.20%, 87.20%, and 84.20%. As for the variance, Gargantoonz falls into the high range and is rated 8 out of 10 by the provider. The max payout is 7,000x the stake, which isn’t bad at all, but we expected a bit more to be honest. In comparison to the last Gigantoonz pokie (4000x) it is actually quite an enhancement. The max win probability is 1 in 100,000,000.


With a lot happening in Gargantoonz pokie we hope our review provides you all the information you need to decide whether this game fits your needs. This game is readily available in New Zealand for your spins so it is always recommended to check out the free demo first before you make your real money spins. This is yet another online pokie that works with cluster pays and it’s once again a game that falls into the Toonz-series. This sounds rather promising, but the 7000x the bet max payout may be a bit disappointing. As for the visuals, sound effects, and bonus features, this game is everything but disappointing. Play’n Go is not known for reinventing the wheel, and Gargantoonz is a good example of how to launch a decent game with moderate efforts. Triggering the features is not easy, but once you do, you will have a chance to have fun and potentially take in some major prizes. Our guess is that most players familiar with other instalments in the Toonz-series will enjoy this game as much as we did during our review.
