Reactoonz features a vibrant and quirky space alien theme. The design is playful and futuristic, with the grid set against a deep blue cosmic background. The graphics are colorful and cartoonish, with a host of adorable one-eyed and two-eyed alien characters. An energetic, electronic soundtrack and zany sound effects for wins and features create a fun and highly engaging atmosphere for this mobile slot.

Regular Symbols: The symbols are eight different alien creatures. The four one-eyed aliens are the lower-paying symbols, while the four larger, two-eyed aliens offer higher payouts. The pink two-eyed alien is the most valuable. Wins are achieved by landing a cluster of 5 or more matching symbols.

Special Symbols:

  • Wild Symbol: A vortex of energy acts as the Wild, created through Quantum Features or by the Gargantoon. It substitutes for all other symbols. There are no traditional scatter or bonus symbols; features are triggered via a charge meter.

Playing this free slot machine is a unique experience. Simply set your bet using the controls and press spin. Winning clusters will disappear, and new symbols will cascade down to fill the gaps, potentially creating chain reactions of wins from a single spin. A demo mode is highly recommended to get a feel for the complex features. Reactoonz is fully optimized for a flawless performance on all mobile devices.

Quantum Leap Charge Meter: Every winning cluster contributes to the Quantum Leap charge meter. Once a section is filled, one of five Quantum Features is randomly queued:

  • Implosion: Transforms 3 to 6 symbols into wilds and destroys adjacent symbols.
  • Alteration: Chooses one low-paying symbol and transforms all instances of it into another symbol.
  • Demolition: Destroys all one-eyed alien symbols.
  • Incision: Puts a wild in the center and creates two diagonal intersecting lines of the same symbol.
  • Gargantoon: If all five meters are charged, the Gargantoon is released! A giant 3×3 wild lands on the grid, then splits into two 2×2 wilds, and finally into nine 1×1 wilds.

Instability & Giantoonz: On any non-winning spin, the Gargantoon can randomly drop 4 to 8 wild symbols onto the grid. If you form a 2×2 square of matching symbols, they merge into a Giantoonz, which doubles the win for any cluster it’s part of.


RTP: The RTP of this casino game is 96.00%. This is a solid industry-standard figure that offers a fair theoretical return to players.

Volatility: This is a high volatility slot. It’s designed for players who love dynamic, action-packed gameplay. The cascading wins can lead to long and exciting chains, but the massive payouts are found when you manage to charge the meter and unleash the mighty Gargantoon.


Reactoonz is a true icon in the world of online slots, and for good reason. Its gameplay is incredibly innovative and engaging, offering a level of action that few other games can match. The build-up of the charge meter and the anticipation of releasing the Gargantoon is a genuine thrill. If you’re looking for a high-energy, feature-packed slot experience, we can’t recommend Reactoonz enough. Give it a spin and join the alien invasion!
