Gigantoonz slot features & bonus games
Despite missing some of the features of its predecessor, the Gigantoonz slot game still offers plenty of bonus action. In the base game, non-winning spins could randomly receive five to ten quantum wilds.
Mega Symbols
Mega symbols come in varying sizes and offer a random cluster value when forming wins. Mega symbols forming part of a win will leave a wild behind when disappearing.
If a mega symbol can’t move during a tumble, all unoccupied spaces will fill with a 1×1 version of the symbol.
Quantumeter
The symbols from winning clusters fill the Quantumeter, which triggers four modifiers at different levels:
Disintegration: reach 25 charges to remove all instances of four randomly chosen symbols.
Metamorphosis: reach 50 charges to transform all one random symbol into a different symbol.
Radiation – collect 75 charges to receive up to four mega symbols and two to five wilds.
The final level is Gargantoonz, which is triggered when you collect 100 and occurs in two steps: first, all mega symbols turn into mega Gargantoonz, so you have a minimum of three on the grid that won’t disappear after forming a win. Plus two to four Gargantoonz appear. Next, mega Gargantoonz breaks into 1×1-sized Gargantoonz that are removed following a win.
Bet sizes, max win & RTP
Gigantoonz offers an RTP of 96.25% and a max win potential of 4,000x.
You can alter your bet from 0.20 up to 100 using the console, where you’ll also see the green spin button and orange auto spin.
