Reactoonz may come off as a complicated slot, but it is not. The high-octane game is fun to play, albeit highly volatile. The cluster pays mechanic allows multiple chances for paying combinations per round. The Quantum Leap charge is perhaps the most exciting part of the game, offering unique rewards like Implosion, Alteration, Demolition, and Incision. The Gargantoon feature is the cherry on the cake that can drive payouts higher than 4,500x the bet.

Reactoonz Slot Review

Reactoonz Slot is one of Play’n Go’s biggest hits released in 2017. The alien-themed pokie is best known for its cluster pays mechanic playing on a 7×7 grid. Instead of bet lines, Reactoonz pays when 5+ icons line up horizontally or vertically. The payouts come from cute little monsters for bets between €0.20 and €100 per spin. For the highest bet, paytable wins rise up to €75,000. Even more electrifying are the bonus features like Gargantoon, Instability, Quantum Leap, and Giantoonz that take players further down the alien rabbit hole. The trippy experience has the potential to pay up to 4,570x the stake.

Reactoonz – Funny Little Critters

Reactoonz slot machine transports players to an alien planet full of wide-eyed little creatures ready to empty their pockets to lucky players. A 7×7 grid occupies the centre as Gargantoon snores in the corner. He can wake up and electrify the reels with bonus features before sliding back into a deep sleep once things die down. The cool blue backdrop gives the game a final out-of-this-world pop that stretches across the screen.

How to Play

The other-worldly appearance of the Reactoonz slot machine does not affect the simplicity of its gameplay procedure. The usual Play’n Go pokie strategy applies and goes as follows:

  • Click on the three-lined button at the bottom right corner of the game screen
  • Using the ‘Bet’ sliding bar, select a stake between €0.20 and €100
  • Set between 10 and 100 autoplay spins that can stop by limiting the balance increment, balance decrement, and single win amounts
  • Alternatively, click the ‘back’ button at the bottom
  • Use the green button above the sleepy monster to set the slot in motion

The Reactoonz demo slot available on our site is the perfect way to get familiar with the gameplay before trying for real money in Play’n Go online casinos. The set runs seamlessly on any device in instant-play mode.

Symbol Wins

Reactoonz Slot spots the cluster pays mechanic that grants winnings for 5+ horizontally or vertically aligned characters of a kind. The simple one-eyed monsters pay the small wins while the two-eyed creatures fire the big guns. The paytable tracks payouts depending on the stake, and those of €100 are as follows:

Icon Wins for
5 6 7 8 9 10+ 12+ 15+
Yellow monster 10 15 20 30 60 80 100 300

Reactoonz Bonuses

The bonuses in the Reactoonz slot game are just as unique as the slot setup and contribute significantly to symbol payouts. Here’s a closer look at each potential reward:

  • Cascading reels

Reactoonz Slot eliminates any icons used in winning clusters before replacing them with new symbols from above. The tumbling continues until no more paying combinations are in view.

  • Gargantoon

This sleeping monster wakes up when the Quantum queue reaches it. The 3×3 monster teleports to the grid and becomes wild. The Gargantoon divides and moves into random positions with each cascade. For the first round, it transforms into 2×2 wilds before becoming nine 1×1 wilds. New icons must fill the playtable before each move.

  • Instability

If a new spin does not result in payouts, there is a chance that the Gargantoon will wake up and drop four to eight wilds on the grid. The icons appear on random tiles.

  • Quantum Leap

The glowing meter to the right of the Reactoonz playtable charges up as more paying clusters explode off the screen. Winning on 25 icons consecutively awards one of these Quantum Features randomly:

Quantum Feature Effects
Implosion Changes 3 – 6 characters into wilds while destroying all symbols adjacent to them
Incision Cuts through the centre to place a wild where intersecting diagonal lines meet through the grid. Both lines display the same icon
Demolition Destroys all instances of one-eyed monsters
Alteration Selects a random one-eyed monster and changes all matching characters into another icon

The Quantum Leap can queue up to four features at a time. The fifth charge wakes the Gargantoon and his special wilds. When no more winning clusters land, other Quantum features in the queue activate. The round ends after all the features play and no more winning combinations appear.

  • Giantoonz

When four matching icons land adjacent to each other in a square formation, they merge to form Giantoonz. These symbols double the value of any payouts they help to trigger.

  • Fluctuation

A random one-eyed critter is marked as the fluctuating icon with a bright halo in each spin. If the marked character is part of a paying cluster, it will leave two wild icons behind.

RTP and Volatility

Play’n Go slots are not famous for higher-than-average RTP percentages, and the same goes for Reactoonz. The pokie spots a theoretical return rate of 94.51% alongside high variance. This math model is not too brutal, considering wins can climb close to 5,000x the stake.

In Brief

Reactoonz Slot is an iconic Play’n Go grid slot, and it is easy to see why. The stunning visuals stand the test of time, and the bonus features deliver a thrilling experience. Over the years, the pokie has inspired other popular releases playing with the same template like Reactoonz 2, Tome of Madness, and Gigantoonz.
