Gargantoonz Bonus Features

Here are tons of bonus functions in this slot that make playing it highly lucrative. These are Cluster Pays and Avalanche mechanics duo, five Wilds, and several unique features, which are called here as Experiments.

Cluster pays

There are no pay lines here due to using the Cluster Pays mechanic, paying a reward for the current amount of paying symbols in sight on the playfield (the minimal number of symbols in a winning cluster is 5). But there is just one detail — those identical pictures have to be touching each other, no matter whether horizontally or vertically, since these make a corresponding payout only under this condition.

Avalanche mechanic

Also, here in use the popular Avalanche mechanic that makes winning symbols disappear after the cash prize is awarded. As a result, those made-free places are filled with new pics again, providing a chance to reassemble a winning cluster. The avalanche function has no limits, lasting as long as there are still wins on the screen. That grants you opportunities for a big prize even during the base game. 


There is no Scatter but 5 Wilds here. And each substitutes payable symbols to increase your chance to strike a winning combination. The regular Quantum Wild is a special symbol that appears randomly or by Fluctuation and Discharge functions. The others are connected to the corresponding Wild Experiment except for the Gargantoon Wild. Let’s dive into their detailed explanation.

Gargantoonz Slot - Wild Symbol


One paying symbol is randomly chosen for every single base game spin as a Fluctuation one. When a cluster compiled of those Fluctuation pics wins, 1 or 2 Quantum Wilds appear in their place after winning symbols are removed from the play grid thanks to the Avalanche mechanics.


This function occasionally triggers in case of non-winning base game spin, granting 2 — 4 Quantum Wilds landing on randomly chosen places.


Here are 3 types of experiments, each one with a corresponding Wild. Let’s observe all of them in more detail.

Experiment Charger

This charger has 2 states. The first state is when there are no active experiments. In such a case, you need to fill it out with 20 symbols from the winning clusters to trigger a randomly chosen experiment. If any experiment is enabled (the second state), complete it by collecting 40 symbols. In this case, the next one will be immediately activated. Every single experiment charges the charger using its own unique Wilds.


An experiment, each time, is chosen randomly, but only when finishing all winning cascades, after wins are credited to the balance. Upon the experiment's start, some corresponding Wilds are added to the playfield, and all the already presented on the play grid Quantum Wilds turn into these unique special symbols.


Successful completion of all 3 experiments activates the last stage of this feature, awakening the most profitable Wild, Gargantoon, which we will talk about a bit later.

Gamma Ray Burst

When such an experiment starts, 7 to 9 Wilds are at randomly chosen places added to the playfield. They count all the symbols from all the winning clusters that were compiled due to Wilds and remove them. After that, all identical to the winning symbols are counted and cleared from the rest of the play grid. After all of that, before any possible Avalanche cascade initiates, Wilds disappear to charge the experiment charger


This charging process can continue after the following cascade thanks to the occasional landing of Quantum Wilds that immediately turn into corresponding ones to the current experiment. And, due to that, all those previously descriptive actions will be repeated until there are no Wilds on the screen.

Black Hole

First up, 4 — 6 Wilds are added to the play grid. They count symbols of their clusters, remaining on the screen until there are wins. After finishing all the winning cascades, Wilds collect any adjacent symbols and disappear to charge the charger. In the case 3+ Wilds took part in the same winning cluster, special symbols immediately leave the play grid to charge the charger instead of remaining on the screen.

Gargantoonz Slot - Black Hole Feature


After the experiment starts, 3 — 5 unique Wilds are landed on the playfield on random tiles. Wilds count all the symbols from the winning clusters they are partaking in, staying on the playfield all the time while there are wins. If there are no more winning clusters, every Wild goes 8 steps, each in a random direction, collecting paying symbols on its path. After that, Wild symbols leave the screen to charge the experiment charger. In the case 3+ Wilds took part in the same winning cluster, special symbols immediately leave the play grid to charge the charger instead of remaining on the screen.

Gargantoonz Slot - Black Hole Feature


After the three Experiments are completed in one go, the last 4th stage with the Gargantoon Wild starts. First, you will get 8 Gargantoon Wilds of 1x1 size. Then they will unite into the 2 Wilds of 2x2 size. Eventually, there will be just one big Gargantoon Wild of 3x3 size. Also, a multiplier up to x4 can be applied to its wins. But, even if several Wilds with an appropriate multiplier partaking in a cluster, only one of those will be used for win multiplying.

Our Experience Playing Gargantoonz

To analyze this slot from the point of view of winning possibilities, we played a 300-spin session using a €1 stake, whereas the overall balance amount totaled €200.


The first round of 100 spins brought us 3 Discharge activations and seven Experiments. The first generated €6.2, whereas the last ones — €18.8. The number of base game wins was impressive since there were as many as 39. Sadly, most of them, 32, turned up lower than the stake. The minimum prize was €0.1, whereas the biggest one - €16.1. After the end of the 100th spin, our balance amounted to €192.9.


The second hundred spins brought the only Gagrantoon Wild activation through the game. Luckily, this feature earned us a lot - €107. Also, there were Discharge and Experiment triggers, which made us correspondingly  €5.4 and €14.9. Despite a solid number of base game wins (43), most were lower than €1, while the biggest prize amounted to just  €3.2. But a big Gargantoonz function win granted us an opportunity to be glad of a €216 balance after the 200th spin ended.

Due to the lack of profitable Gargantoonz feature triggering, the last hundred spins made us suffer losses. Other bonus features brought us just €1, while the biggest regular cash prize, this time, was €5. As a result, the final balance amount after the 300th spin totaled just €153.6. Hence, during these 300 spins, we lost precisely €46.4.

As you can see, there are frequent wins here. Yet, most of them are not that high. Therefore, the main profit in this slot is delivered by those bonus features with various Wilds in charge. Moreover, the only way to get the big prize here is to wait for the triggering of the well-generous Gargantoonz feature.

Gargantoonz Verdict

This video slot is full of bonus features and animations. Due to that, it may first seem a little complex to embrace in terms of its rules. Yet, just a few minutes of playing will give you a good enough understanding of what is going on in the playfield. That's a perfect choice for players who want to try something new without usual respins or free spins. Moreover, who would refuse to get a solid max win of x7,000 by the stake?


Yet, we weren't impressed by the regular wins, the biggest of which, through all our 300 spins, was just €16.1. On top of that, most of the base game prizes turned out lower than the currently chosen bet (€1). Hence, bonus features here — the only way to get a solid reward. Yet, not all of them are as generous as Gargantoonz. Also, make sure you're playing the slot with the best RTP since there are as many as five different possible values, just one of which (96.2%) is higher than average.


Therefore, if you like trying something new and prefer somewhat more complex gameplay than in the classic fruit slots or are just a fan of the ‘toons’ series, it's a brilliant choice that will not only pay but also be guaranteed to entertain you. Given there are so many bright-colored features pleasant to watch, don't miss your chance to get some euros as a win and a lot of excitement due to playing this slot.
