Play Reactoonz Online
The Reactoonz demo slot is a lively and bright game where players are put in a cartoon alien world inhabited by slimy and funny aliens. The game is played on a 7 by 7 grid, and winnings are granted for clusters of five or more identical symbols that touch horizontally or vertically.
With each cascade, winning symbols fall out and new ones appear in their place. This can create more winning combinations and raise the total win for the spin. The main objective is to gather energy and use the mysterious alien Gargantoon’s bonus effects.
Slot Features
The game is distinguished by its distinctive mechanics, which include the absence of conventional reels and paylines, the inclusion of cascading wins, and a system of cumulative bonuses known as Quantum Features. The energy from winning combinations builds up and can destroy some symbols, turn them into wild ones, or change the way the field is set up if a spin fails.
Gargantoon can add four to eight Wild symbols to the field on its own if a spin doesn’t work. The odds of a big win are also greatly increased if four identical symbols form a 2×2 square because they transform into a giant Giantoon symbol with an x2 multiplier.

Wild can only show up after certain things happen:
- Gargantoon’s intervention;
- Bonus activation;
- Special symbols are destroyed.
