Gargantoonz is a slot machine by Play'n GO. According to the number of players searching for it, Gargantoonz is not a very popular slot. Still, that doesn't necessarily mean that it's bad, so give it a try and see for yourself, or browse popular casino games.
To play for free in demo mode, just load the game and press the 'Spin' button. You can learn more about slot machines and how they work in our online slots guide.
Gargantoonz is themed around a gang of adorable aliens.
Players will travel through a twinkling galaxy where they will meet some extraterrestrial friends. Each colorful creature will help players discover the secrets of the universe.
Fans of previous Garga franchise slots will particularly appreciate this incarnation.
The soundtrack of Gargantoonz has an 80s vibe, bringing to mind retro sci-fi films. The Gargantoonz themselves occasionally make cooing noises that add to their cuteness.
Behind the reels, players will see a cartoon spacescape with many sparkling stars. This creates an enchanting atmosphere and establishes the Gargantoonz alien status.
The stars of this slot are the Gargantoonz themselves who come in a range of colors. Each little creature has a welcoming smile that makes them immediately endearing. Some have one eye while others sport spikes and horns.
Beside the reels, a sleeping Gargantoon can be found in a glass chamber. Players will feel curious to find out how their alien technology works.
Overall, the soundtrack and animation create a playful, extraterrestrial world.
Gargantoonz is a seven-reel, seven-row slot.
Wins are awarded for landing clusters of at least 5 matching symbols. Matching symbols must be connected horizontally or vertically.
The maximum win for this slot is 7,000x the player’s total bet.
Gargantoonz has five Wild symbols which substitute for all symbols.
During each round, a one-eyed symbol is selected at random to fluctuate. When fluctuating symbols form winning combinations, 1-2 Quantum Wilds will appear where the symbol disappears.
During non-winning rounds, 4-8 Quantum Wilds can be added to the reels at random.
Winning combinations have the ability to charge a special charger when no Experiments are active. It takes 20 symbols in total to charge the charger in this state.
After the charger has been filled, an Experiment is chosen at random to become active. If this Experiment is successful, another Experiment begins. This continues until all 3 Experiments are finished. However, the sequence ends if an Experiment is not successful.
Experiments consist of special selections of Wilds appearing on the reels and enhancing winning combinations.
Every successful Experiment also charges the Gargantoon charger, prompting the Gargantoon to evolve. The Gargantoon charger begins with a multiplier of 1x that increases by 1 with experiment charges.
When players achieve 3 successful Experiments, the Gargantoonz feature begins. During this feature, Gargantoon Wilds have the ability to merge and become extra large. These Gargantoon Wilds also have associated multipliers.
The return to player of this game is 96.20%, slightly above our yardstick for an average of roughly 96%.
The range of bets on the site we tested ran from a minimum bet per spin of $/£/€0.10 up to a maximum of $/£/€100 per spin.
High volatility makes this slot a good match for our preferred slot machine strategies. We suggest pursuing the highest volatility possible when selecting slots.

Fans of this franchise will especially adore the selection of endearing alien creatures, as well as the selection of bonuses.
Mathematically-minded players will find the decent RTP and impressive volatility appealing.
