Gigantoonz Slot Game Reaching Gargantoonz 100 Level

Gigantoonz is a space-themed video slot by Malta-based games developer Play’n GO. The title is the latest instalment in the Toonz series of slots, which also features Reactoonz, Reactoonz 2, and Dr. Toonz.

Those who have played the prequels will notice that Gigantoonz is very similar in design to the previous titles, and the wagering mechanic is pretty much the same. However, the game grid has been upgraded from 7×7 to 8×8 in Gigantoonz, and the developer also made some adjustments to the maths model.

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.
