Gigantoonz is a video slot created by Play’n GO in 2022. The game is a follow-up to the Reactoonz or Dr Toonz video slots, and it is set in outer space. Its background image is an eye-catching purple galaxy.
Symbol designs in the Gigantoonz slot will be instantly recognisable if you enjoyed the Reactoonz or Dr Toonz slots, as the colourful cast of aliens or Toonz appear here alongside unique symbols like the swirling ball of energy that is the wild symbol.
Gigantoonz Slot Basics
The Gigantoonz slot uses an 8×8 grid and the cluster pays mechanic. The slot has an RTP of 96.25% and is highly volatile, which means you’re more likely to make large, infrequent wins when playing. Your minimum bet per round is £0.20, while the maximum is £100. The top prize you can win in the game is 4,000x your total wager. Forming a winning cluster requires you to land six or more matching symbols touching horizontally or vertically.

The red Toonz is the most valuable symbol. At the maximum bet level, it pays £100 for six symbols, £200 for seven symbols, £500 for eight or more, £1,000 for 10 or more, £2,000 for 12 or more, £5,000 for 17 or more, £10,000 for 21 or more, £20,000 for 25 or more, and a maximum of £125,000 for 30 or more symbols.
After that, the pink Toonz pays £40,000, the green Toonz pays up to £20,000, the orange Toonz pays a maximum of £10,000, the blue Toonz pays up to £5,000, the one-eyed blue Toonz pays £2,000, the one-eyed pink and red Toonz pay £1,000 each, and the one-eyed green and yellow Toonz pay a maximum of £500 each.
Special Features
The Gigantoonz slot comes with several special features, including mega symbols in which every symbol can appear in various sizes ranging from 2×2 to 7×7. The block acts as a single symbol while awarding a random cluster value of up to 13.
When a mega symbol awards a prize, it leaves behind a wild symbol. Meanwhile, on any non-winning spin, between five and 10 wild symbols can be added to the reels. Wild symbols substitute for other symbols to help make more winning combinations.
Cascading reels remove winning symbols from the grid. New symbols fall from above to replace them, and this can make new winning combinations that continue the cascading reaction. Cascading reels are essential to progressing the quantumeter. Every winning symbol is counted as one charge towards the quantumeter while mega symbols add their total cluster values.
The quantumeter has four charge levels and holds up to 100 charges. Filling each level triggers a respective special feature once all cascades have been completed on your current spin.
Earning 25 charges grants the disintegration feature, where four randomly selected types of symbols are removed from the reels. Earning 50 charges triggers the metamorphosis feature, which transforms all symbols of one type into mega symbols. Earning 75 charges triggers the radiation feature, which adds up to four mega symbols and between two and five wild symbols to the reels.
Finally, earning all 100 charges triggers the gargantoonz. When this happens, all mega symbols transform into mega gargantoonz. At least three gargantoonz symbols will appear, regardless of how many mega symbols are on-screen. What’s more, up to four 1×1 gargantoonz symbols will appear. After this, the mega gargantoonz will break down into 1×1 gargantoonz symbols, which are removed as normal.
