What was our first reaction?

Like its prequel Energoonz, the Reactoonz slot from Play’n GO features a playful parallel universe charged with stellar power and prizes. Released in 2018, this alien-themed slot has been exciting players ever since with its wealth of bonuses and interactive aliens, including the power-hungry Gargantoon who snores in the corner of the screen until he’s energized enough to leap onto the reels.

Overall rating

This Reactoonz slot review will look further into the game’s bonuses and specifications. However, first, let’s see what you will encounter on the reels. There are 4x two-eyed aliens, 4x one-eyed aliens, and Gargantoon the 3×3 monster who acts as a wild and substitutes for all other symbols. Other wilds will be discussed further in the bonus features.

Reactoonz slot features cascading gameplay and cluster wins. Match five or more aliens that touch horizontally and/or vertically for a win, and symbols are removed, and others fall down to fill the gaps. The standard bet range offers minimum bets of 0.20 up to 100 max bet.

This Reactoonz slot review has discovered that it is a highly volatile bitcoin slot with a high 96% RTP. Played out on a 7×7 grid, players have a chance to hit the max potential win of 4,570x bet during the Quantum Leap features.

Reactoonz Bonuses and Features

Quantum Leap – following every successful spin on the Reactoonz slot, players start to fill up the Quantum Leap charge meter. A random feature is added to the line after winning on 25 symbols. Up to four Quantum features can be lined up: Implosion, Demolition, Incision, and Alteration. Charging a fifth time will awaken the Gargantoon.

When there are no more wins present on the grid, the collected Quantum feature(s) are triggered. Gargantoon, who starts as a 3×3 wild, divides and moves with every cascade. First, it becomes two 2×2 wilds and then it splits into nine individual wilds.

  • Instability – on any non-winning spin, players may be treated to the Gargantoon dropping four to eight wilds onto the grid.
  • Giantoonz – four matching symbols that form a 2×2 square shape automatically form Giantoonz and all wins are doubled that they are part of.
  • Fluctuation – one random one-eyed alien is marked as a fluctuating symbol in each spin. If it forms part of a winning combination, it leaves behind two wilds that substitute for all symbols.
  • Wilds – wilds are not affected by Quantum Leap features and can only appear during Fluctuation and Quantum features.


Reactoonz slot can seem fairly complex at first with all of its various bonus features, cascading gameplay, and cluster wins. However, once players get started, it all becomes pretty clear. There is a high 96% RTP and volatility on the slot, which will appeal to those with deeper pockets. However, it also means a wait in between those bigger wins.
