Gargantoonz is an alien-themed video slot from Play’n GO played on a 7×7 grid with a cluster pays system and a theoretical RTP of 96.20%. Wilds, cascading reels, multipliers and merging symbols drive the action, and the top payout reaches 7000x the bet. Read on for the specs, symbols and features.

Gargantoonz belongs to Play’n GO’s “toonz” series. Besides the Wilds, the feature list includes mini bonus features, collecting symbols and multipliers, so it suits players who like a busy, layered game.

RTP is a theoretical long-run figure, so it says nothing certain about a single session. For more, see our guide to what RTP means.

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.
