Gargantoonz Online Slot Review

The Gargantoonz slot from Play’n GO is a sci-fi themed game filled with cartoon monsters across a 7x7 grid. It’s part of a popular series that features similar characters, and like the others it’s packed with exciting gameplay and features.

Unleash these critters across PCs or mobiles to trigger cascades on every win and special modifiers awarded as an Experiment Charger fills to the side of the reels. These include extra wilds that can substitute for others to create more wins, move around the grid, and stick in place. Wilds also summon a Gargantoonz monster to the game, and he gradually becomes a giant 3x3 symbol with valuable multipliers.

It's a high volatility slot with average returns of 96.20%. Explore outer space with the Gargantoonz at a recommended online slots uk site and you can win as much as 7,000x the stake.

How to Play the Gargantoonz Slot Online

Green, blue, red, and yellow floating head creatures with cheerful grins and a range of shapes feature here. These delightfully animated characters sit against a backdrop of stars, surrounded by meters to the left and right, and a sleeping Gargantoon alien in his pod. They make little cartoonish noises as the 7x7 grid spins, adding to the cheerful soundtrack.

Look to the controls below the reels on your PC, Android, iOS, or Windows mobile on your chosen Betting Apps and you find a scroll bar. Toggle to the left or right and you can pick a stake from a range of 0.10 to 100.00 per spin. 

Gargantoonz has a cluster pays system where you win prizes when at least 5 matched symbols land connected together horizontally, vertically, or in blocks. Click the ‘I’ button at the bottom of the game to reach a paytable that lists how much each symbol pays at your chosen bet level. Land the top-paying red monster on 5 places to win 1x your stake, increasing to 1,500x if it’s in clusters of 18+.

Players outside the UK have a couple of extra control options, including autoplay, triggered via the arrow in a circle button, and the lightning bolt right at the bottom of the game activates a quick spin mode.

Wild Symbols & Other Gargantoonz Slot Features

Any symbols in a winning cluster vanish to trigger cascades of those above. New symbols fall in from the top and you get an unlimited number of cascades until there are no new clusters in view. 

There are several different types of wild symbol here, and while they all have the power to substitute for others if needed, they each work in slightly different ways. 

A Fluctuation occurs on every spin, as a random low-paying symbol is chosen and if it’s part of a win 1 or 2 Quantum Wilds are added to the grid for the following cascade. Discharges happen randomly on non-winning spins, as 4 – 8 wilds appear on the reels. 

All symbols in a win and over any series of cascades will collect in an Experiment Charger. If it fills with at least 20 symbols, it awards an Experiment at the end, and you can benefit from 3 Experiments if enough symbols collect in the meter. Only wilds collect in the Charger during their features. Here’s what you get in the order they trigger –

Gamma Ray Burst – 7 – 9 wilds are placed on the grid. Any wilds in a win count the number of symbols in their cluster before removing them, then count and remove any others of the same type. 

Black Hole – 4 – 6 wilds appear, and any win a win remain in place until part of another win. Once any cascades end, they collect all adjacent vertical and diagonal symbols for another cascade. 

Supernova – 3 – 5 wilds are placed on the grid, and they move around if part of a win. Wilds can move as many as 8 steps, collecting symbols along the way.

Experiments charge the Gargantoon meter, improving a multiplier and waking the alien from his slumber. If all 3 Experiments fill the meter, 8 Gargantoon wilds appear on the grid. They help to complete wins, with their multipliers active and once any resulting cascades end, the wilds merge into 2 wilds, each 2x2 size. Once cascades from these wilds come to an end, the Gargantoon become a single 3x3 wild in a third and final stage.

Our Gargantoonz Online Slot Rating

At first glance, this can seem to be a complicated game, but once symbols collect in meters and unleash wild modifiers, you’ll see that it all comes together. Experiments will usually lead to wins, and if all 3 trigger, they wake the Gargantoon for some big wins.

Fans of others in the same series, such as Reactoonz 1 and 2, or Dr. Toonz, will flock to this version, but even if you are new to the cute monsters, you are sure to enjoy the action-packed gameplay of Gargantoonz. Meet them all at the best online Casino Sites featured here at
