Gargantoon — the signature mechanic
The Gargantoon is a 3x3 wild that lands randomly. How it behaves:
- Lands on 9 positions (a stacked 3x3 block)
- Moves across the grid on every cascade
- And splits into smaller wilds (2x2, then 1x1)
- Multiple simultaneous Gargantoons create massive overlapping combinations
This is the signature mechanic that makes every Reactoonz session feel different.
The 4 Quantum modifiers
During cascades, 4 modifiers trigger automatically (at random):
- Implosion: turns low symbols into premium symbols
- Demolition: destroys every low symbol
- Incision: adds a cross of wilds
- Alteration: turns every symbol of one type into another
Combined with the Gargantoon and Giantoonz multipliers, this is the path to the 4,570x max win.
