Reactoonz Slot Review

Reactoonz is a 2018 video slot, released by Play’n GO, which has been a fan favourite from day one. The game uses cascading symbols and continuous wins to create a rewarding gaming experience, while the artistry and movie-like animations make Reaztoonz powerfully immersive.

An extremely volatile game, players can win thousands of times their stake on every spin, with an onslaught of special features providing multipliers, huge combos, and lengthy win streaks!

How to play the Reactoonz Online Slot Game

Reactoonz is not your typical video slot. There are no reels or free spin rounds, the action is incredibly fast-paced and exciting, and the number of special features could knock your socks off – so how do you play?

The game uses a cascading game engine (rather than traditional spins) within a 7×7 grid. Clusters of 5+ symbols generate wins: the more symbols, and the more valuable the symbols, the higher the payouts. For winning spins, the contributing symbols are evaporated and new symbols fall down to take their place – this is the game’s key feature.

If new symbols fall and create further winning combinations, the process repeats ad infinitum. Winning doesn’t just accumulate payouts, it also charges the Quantum Leap meters, leading to special features discussed deeper in this review.

In terms of on-screen interaction, there are a few buttons to contend with:

  • Information (i) – This menu explains how the game works, its special symbols, and contains the payout table.
  • Balance – The player’s balance in dollars.
  • Bet – Players use the arrows to select their preferred bet amount, which is confirmed in the small screen to the left of the spin button.
  • Spin button – Activates the reels.
  • Autoplay – Dictate autoplay rules like number of spins, max win/loss, etc.

Graphics and Sound

Reactoonz is a super-modern game in all facets of its design and the whole screen is a work of art. There’s the win meter off to the left, the Quantum Leap charger and Gargantoon off to the right (peacefully sleeping between spins!) and all sorts of colourful action in between!

All the symbols are cute, one and two-eyed smiling little aliens. They drop onto the reels with a satisfying squelchy sound and explode impressively when part of a winning combo. The futuristic background music and Gargantoon snoring is pleasant to listen to (even over a prolonged period) and the jazzy and varied sound effects during cascaded wins are enchanting.

Admittedly, the game is a little overwhelming at first: there’s a lot going on, and it’s pretty hard to keep track of it all. Once the game’s actions are a bit better understood, however, cascading wins make for a remarkable spectacle!

Rotate the screen


While Reactoonz doesn’t maintain a triggerable jackpot in the traditional sense, it is extremely volatile and pays out handsomely. Any combination of Quantum Bonuses, energy wilds, Gargantoon wilds, and the Giantoonz multiplier can see players win thousands of times their stake with ease.

There is no real “maximum payout” since players can continue to achieve cascading wins virtually indefinitely!

Special Features and Symbols

There are two levels of symbol in Reactoonz: those with two eyes, and those with one eye! Two-eyed aliens pay the most, with the pink one paying up to $75,000 for 12+. There is also a wild symbol but no scatter.

Quantum Leap

Successive winning combinations (25 symbol totals) will fill the Quantum Leap meters to the right. These keep filling until no more spins are available, at which points its special features are activated! If the meter charges a 5th time (there are only 4 special features) then the Gargantoon (see below) also gets involved. The features:

  • Implosion – Turns 3-6 symbols into wilds and destroys all adjacent symbols.
  • Incision – Places a wild symbol in the center of the grid, then creates a full-grid X of matching symbols!
  • Demolition -Destroys all one-eyed symbols and all matching symbols.
  • Alteration – Selects one random one-eyed symbol and transforms all its iterations into another symbol.

Giantoonz and Fluctuation

Giantoonz are formed when 4 matching symbols fall together in a 2×2 grid. They merge into one single 2x multiplier symbol, doubling any wins they contribute to. Players will notice that one symbol on every spin is highlighted with a soft glow: if any glowing symbols are part of a winning combo, they leave behind at least two wilds in their wake, to promote further wins.


This is the big fellow snoozing to the right of the screen. He can cause Instability (see above) on any non-winning spin to increase the likelihood of winning. If triggered through the Quantum Leap feature, he jumps onto the grid as a 3×3 wild. For the next cascade, he becomes two 2×2 wilds, then nine individual wilds.

Gargantoon leads to some crazy wins!

There’s a reason that Reactoonz is one of the most popular slots of recent years: it ticks every box! Yes it is highly volatile, which means some players will go long periods without winning, but the life-changing rewards the game pays out are absolutely worth it.

The unique game engine, the heaps of special features which combine beautifully together, the stunning design and flowing animations – we cannot recommend playing Reactoonz highly enough!
