Game Features

Reactoonz interface

Reactoonz is a fun, action-packed video slot developed by Play'n GO that hit online casinos in 2017. It's the prequel to the popular Energoonz, which also has a cartoon-alien space theme.


At first glance, Reactoonz can seem a touch confusing. The slot is housed on a large 7 by 7 grid with futuristic meters and counters either side.

There are no reels as such due to it using the cascading wins game engine. This delivers multiple wins from a single spin and a feature-rich adventure that can pay out 4,570 times your stake.

How to play Reactoonz

With there being no paylines, all you have to do to start playing is select your bet value which ranges from €/£0.20 up to €/£100.

Winning combinations are formed when you land clusters of five or more of the same symbols on the grid.

These winning clusters explode and all the symbols drop down to fill out the grid again. This sequence repeats itself over and over until there are no more winning clusters.

Bonus Rounds and more

When you hit some winning clusters, you start to fill the five Quantum Leap meters to the right side of the grid. It takes 25 winning symbols to fill one meter.

When the winning combos stop, each full meter will randomly release one of the following features:

  • Implosion - Three to six symbols transform into wilds and each adjacent symbol explodes.
  • Incision - A wild is placed on the centre of the grid and an 'X' shape is formed from edge to edge by two diagonal lines. All symbols within the 'X' transform to the same one which is chosen at random.
  • Demotion - All low-value symbols on the grid are destroyed by a laser.
  • Alteration - One symbol is randomly chosen and it transforms into another symbol.

If you manage to fill all five Quantum Leap meters from a single spin, the Gargantoon feature is added to the queue. This inserts a massive 3x3 wild on the grid, as the symbols cascade, it splits into two 2x2 wilds and for the next cascade, it becomes nine single wilds.

Even on non-winning spins, the Gargantoon can release between four and eight wilds randomly onto the grid for what is called the Instability feature.

There is also a Fluctuation feature where one symbol, if part of a winning cluster, leaves two wilds behind. Finally, you have a 2x multiplier known as Giantoonz which is formed when you get a 2x2 set of the same symbols appears on the grid.

Reactoonz strategy, tips & tricks

Reactoonz has a lot going on but the slot still has a high volatility rating. Although we found there to be quite a few small wins, these were only worth between 10 and 20% of the stake.

Therefore, you need to manage your bankroll when playing so you stay in the game long enough to hit a big win. With all the features chosen at random, and no bonus spins to speak of, there isn't much strategy involved - just fun entertainment.
