Theme and Visuals
Gargantoonz is part of the “toonz” series by Play’n GO, and the symbols match the alien theme well. The low-paying symbols are 5 differently-coloured cyclopses, while more complex forms of alien life make up the premium icons.
Symbols and Wilds
There are 4 different Wild symbols. Besides substituting for other icons so you can form more winning clusters, Wild symbols introduce different extras, which are covered in the features section below.
Grid, Clusters and Bets
This online one-armed bandit uses a large 7×7 grid and a cluster pays system. Winning combinations form when 5 or more identical icons connect across adjacent reels, starting from the leftmost reel. Bets range from 0.01 to 10, and the top payout is 7000x the bet.
Gargantoonz Bonus Features
- Experiment feature: each winning cluster fills a meter, and you need to collect 20 winning clusters to activate it. Modifications such as Gama Ray Burst, Black Hole and Supernova each add a different number of Wilds with different effects.
- Cascading reels and multipliers: winning icons are removed and replaced with new ones, with multipliers adding to the action.
- Gargantoonz feature: smaller Wilds can merge into gigantic 2×2 or even 3×3 Wild symbols.
