Reactoonz Slot

The alien overlord Gargantoon has given his faithful minions one mission, gather up the energy he needs to help you capture renegade jackpot wins! Join forces with him in Reactoonz online slot!

Theme, Sounds, and Symbols

Reactoonz is comical alien-themed eye candy! This is a Play’s GO online slot that revels in its silliness and off-the-wall sense of humor!

The first thing you hear upon loading Reactoonz, while you browse the information tab and bet settings, is someone snoring! Yes, this slot greets you with a good old open mouth snore right off the bat! The culprit? None other than Gargantoon himself. It seems the alien overlord gets bored when you don’t do anything and will asleep immediately to remind you to play already!

The other sounds are very much like the mumbles from the actual Minion animated film with the Reactoonz constantly babbling quietly to themselves in response to some on-screen stimulus.

The reels are set against a star-filled alien sky with the 7×7 grid flanked by a Reactoonz kill counter on the left and the Quantum feature engine on the right.

While the multi-eyed multi-horned Gargantoon strikes an imposing figure, he has very little interaction with the reels in the base game.

The split between high value and low-value symbols is an actual interstellar caste system with the aliens with two eyes having far more value in their society than the single-eyed symbols, which are the low-value symbols.

Does this mean that the only reason Gargantoon is their leader is that he has three eyes?!

Game Mechanics

Reactoonz is a cascading reel slot, in the ilk of games like Gonzo’s Quest and Moon Princess, where rather than matching symbols on fixed paylines you need to have 5 or more symbols of the same type connect vertically or horizontally on a 7×7 grid.

Matched symbols disappear, allowing new symbols to cascade down to fill their place and earn you additional winning combinations.

The addition of Giantoonz to the reels increases your ability to string together winning combinations. When 4 symbols make a square, they combine into their hulking Giantoonz form. Even a single matching symbol touching this giant symbol is deemed to be in vertical or horizontal contact with 4 other symbols creating a 5 symbol winning combo.

Reactoonz gives you the power to not only dominate the universe but also manage your budget by providing a broad selection of bet settings. The ability to quickly adjust your bet €0.20 up to €100.00 per spin is going to come in handy as you work with Gargantoon to lay claim to the 91,406 coin jackpot!

Bonus Features

The Reactoonz casino game comes loaded with three special features which are as quirky, and as interesting, like the rest of the game!


On any non-winning spin Gargantoon in his wisdom may choose to randomly drop between 4 and 8 Wild symbols on the reels to help you along in your quest for intergalactic wealth!

Quantum Leap

As you land winning combinations the energy is gathered in the Quantum engine and when fully powered can queue and release the following 4 Quantum Features:

  • Implosion: Up to 6 symbols become explosive Wilds
  • Incision: Cuts an X shaped swathe of Wilds across the grid
  • Demolition: Destroys all one-eyed alien symbols
  • Alteration: Transforms a random one-eyed alien type into another type

Gargantoon Feature

When the Quantum feature is has queued all four Quantum Features you are almost ready to unleash the mighty Gargantoon – all that is needed is a fifth charge, and he will be freed! Freeing him sees a 3×3 monstrous Gargantoon Wild symbol appears on the reels. As he powers winning combinations, triggering cascades, he divides into smaller but more numerous versions of himself. First, he becomes two 2×2 Wilds and then finally, nine 1×1 Wilds fulfilling his destiny of creating winning combinations!

Play ‘On The Go’

Looking to the future Play’n GO knew mobile devices would rule the world and have ensured that Reactoonz is available to play on your favourite mobile device across all operating systems, including Apple iOS, Android and Windows!

Wellknowslots Verdict

Reactoonz is an engaging and entertaining cascading reel slot. The amusing character interactions and transformation as well the special features will provide great entertainment. However, it is key to remember that Reactoonz, for all that is has a 96% RTP, is a high volatility game. Be sure to set your bet limits to a level that will allow you to enjoy the entertainment value of the slot while preserving your budget.
