Reactoonz RTP, Volatility, Details & Limits

Understanding the way a game works is the first step when it comes to being successful at playing slots, and in this case Play’n Go have presented us with a rather expansive 7×7 grid that makes use of Cluster Pays as we’ve mentioned before. This means that instead of landing symbols in a particular formation, you’ll need a group of five or more of the same symbol to land a win.

With regards to the return to player (RTP), Play’n GO are known for their flexibility, which is why we always recommend checking each casino individually if you’re after a particular game. In this case, the range here spans from 96.51% at its highest and 84.51% at the other end.

And lastly, we’ve got a very highly volatile situation going on here, which usually means this game is better suited for high rollers or those with a larger bank roll to spin through.

Reactoonz Theme – Literally Out of This World

Play’n GO launches us straight into outer space with this Reactoonz casino slot that’s been designed to look as though the reels are suspended somewhere out in the galaxy. Each of the symbols on the reels are represented by differently coloured alien lifeforms, while the larger Gargantoon located to your right will occasionally chime in, potentially boosting the reels in your favour every now and then.

The soundtrack is fun and quirky, and we must admit that it’s fun to see aliens being zapped off the reels in exchange for real money wins. There are also a number of other moving parts involved as you charge meters up and launch orbs onto the reels which keep the entertainment factor high for the duration of your gameplay.

Reactoonz Slot Symbols & Paytable

Reactoonz Bonus Features

If you’ve never played Reactoonz before, then chances are that you might be slightly confused at the start as there’s a lot going on, but the good news here is that we’ve got you. Here’s what to expect in terms of special features and symbols.

Gargantoon

The big alien to your right is displayed alongside a large Quantum meter which tops up following every consecutive win that’s brought about by the cascade feature within the game. If this ever fully loads up then the Gargantoon will divide and enter the grid, first as 2×2 wild symbols, and then as nine regular symbols after that.

Instability

On any non-winning spin, this feature may be activated at random and will create an opportunity for the Gargantoon to drop up to eight wild symbols onto the grid.

Quantum Leaps & Features

Landing wins on the reels of Reactoonz will charge up the Quantum Meter accordingly, with the chance of queuing up to four features, and the fifth feature releasing the Gargantoon.

Other Quantum features potentially unleashed onto the grid include:

Implosion Orb – this symbol will transform up to six symbols into Wilds while destroying any adjacent symbols.
Demolition Orb – this symbol destroys all the one-eyed alien symbols and any other matching symbols.
Incision Orb – this symbol cuts Wild symbols into the centre and creates two diagonal lines that intersect at the centre of the grid. Both lines will transform into matching regular symbols.
Alteration Orb – this symbol will select one single-eyed alien symbol at random and turn them into another.

Gigantoonz & Fluctuation

Landing four regular symbols adjacent to one another will automatically merge to create a Gigantoonz that’s double in value. Whenever this symbol forms part of a winning combination it will leave two wild symbols behind on the reels.
