Gargantoonz Slot


Play’n GO are back with another release brimming with colour, this time with the Gargantoonz slot. This game was unveiled to the iGaming space in November 2023 and is one of the many popular entrants that lends itself to the Reactoonz slot collection. With this specific entry into the series, however, the developers have taken a more inventive approach to the gameplay and accompanying bonus mechanics, both of which combine with the fan favourite animated visuals.


Gargantoonz Game Background


Compared to most regular online slots in the UK, the playgrid design in the Gargantoonz slot is much more innovative, with there being 7 reels and 7 rows that comprise the playtable here. Instead of using a payline system, Play’n GO has chosen to use a cluster pay mechanic, something that has become more and more popular in recent years. On both sides of the reels, there are various metres and floating tubes showcasing monster characters; however, these tie into some of the game's bonus mechanics.


When it comes to the backdrop behind the unconventional playtable, this is also creative in its own unique way. This is because the Gargantoonz slot makes use of some space inspired imagery, with the playscreen being painted by a cosmic vacuum populated with distant stars. A blue glow emanates from behind the playgrid here, with this complimenting the darker colour palette used across the backdrop.


Gargantoonz Slot Symbols


No imagery from live casino games has been used whatsoever in the paytable of this Gargantoonz slot. As opposed to the usual card symbols, this release provides a refreshing change by making all the symbols different monster symbols, each in their own distinct vibrant colour and shape.


Lower Value Symbols:

  • Single-Eyed Yellow Monster

  • Single-Eyed Green Monster

  • Single-Eyed Red Monster

  • Single-Eyed Purple Monster

  • Single-Eyed Blue Monster


Medium Value Symbols:

  • Two-Eyed Blue Monster

  • Two-Eyed Yellow Monster

  • Two-Eyed Green Monster


Higher Value Symbols:

  • Two-Eyed Pink Monster

  • Two-Eyed Red Monster


As well as the collection of monster themed base game symbols, the Gargantoonz slot also features a collection of bonus symbols, a number of these being electrical balls. However, instead of landing naturally on a spin-by-spin basis, these could instead be introduced to play should clusters potentially be formed, however, more on this aspect shortly.


Gargantoonz Bonus Features


On any random spin in the Gargantoonz slot, the ‘Discharge’ feature could be triggered in which between 4 and 8 symbols are selected at random to become quantum wilds. These are dark blue electrical balls, with these possessing substituting capabilities like most other wild symbols.


With every base game spin, a random one-eyed symbol is selected to become the ‘fluctuating’ symbol. Should this be involved in a cluster, between 1 and 2 of these aforementioned quantum wilds could be added to the playgrid. This is done following a cascade which removes the involved combinations, with this type of mechanic being popular in Megaways slots and other games with cluster pay systems.


To the right of play in the Gargantoonz slot, an ‘Experiment Charger’ metre is displayed. Should 20 symbols be involved in cascades in the same spin, this could trigger one of 3 random experiments. The experiments in question are as follows:


  • Gamma Ray Burst: Between 7 and 9 wilds randomly added to the reels.

  • Black Hole: Between 4 and 6 wilds added to the playgrid that remain sticky throughout cascades.

  • Supernova: Between 3 and 5 wilds added to the playtable that become sticky and move diagonally with every potential cascade.


With each experiment that potentially forms a cluster, this charges the Gargantooz charger also to the right hand side of the reels. If this is triggered, this could see a giant white monster, that being the titular Gargantoon, added to the reels at random. These are wilds 2x2 in size, with these having the potential to come with 2x, 3x or 4x multipliers attached. This feature also makes an appearance in the Reactoonz 2 slot as well!


Gargantoonz Mobile Play


With all of the various modifiers, progressive metres and bonus rounds included in the Gargantoonz slot, it is even more impressive the fact that Play’n GO has managed to keep this game fully compatible with mobile play. This is something that is applicable to all of these developers' titles at BoyleSports Games, with the impressive detail in this release remaining consistent no matter the screen size.
