Reactoonz is a vibrant 7x7 grid slot featuring cute alien creatures that drop down to form clusters. Winning clusters are removed, allowing new symbols to cascade and potentially create further wins. The game includes a Quantum Leap charge meter that triggers unique modifiers like Implosion, Incision, Demolition, and Alteration upon consecutive wins. Filling the meter fully activates the Gargantoon Wild feature, adding massive wild symbols to the grid for explosive payouts.
