Gigantoonz Slot Setup & Symbols
Just like the previous instalments, the Gigantoonz slot is built around the theme of space and extraterrestrial beings. The game plays out on a grid with 8 reels and 8 rows. To the right of the reel-set is a Quantumeter, which activates four different modifiers when fully charged. A second meter, which displays the number of symbols in each winning cluster, sits on the left side of the screen.
When it comes to the pay table, the reel symbols in Gigantoonz are animated aliens. The aliens with one eye act as the lower symbols, while those with two eyes act as the premium symbols. The machine uses a Cluster Pays engine, which means that you have to form clusters of matching symbols to form a win. The minimum number of icons required to create a winning cluster is 6.
Wild Symbol
Gigantoonz has two types of Wild symbols.
Quantum Wilds
Quantum Wilds can substitute for any of the regular symbols on the reels to form winning clusters.
Gargantoon Wilds
These are special Wilds that only come into play when the Quantumeter is fully or 100/100 charged.
