A Review Of IGT’s Reactoonz online slot

If you like grid games with cascading reels, you are sure to be a big fan of the Reactoonz online slot from game developers Play’n GO.  This game is presented in a 7 x 7 grid format, with 7 different bonus features. The bet range is £0.20 to £100, and you can win up to 4,750 times your stake money on this medium to high volatility slot which carries an RTP rating of 96.51%.

Play’n GO were originally founded in 1997. They became an independent company in 2007 and went on to prove to be one of the leading suppliers to the online casino industry.  They were one of the early pioneers of mobile gambling, and with their adopted brand name, Play’n GO, gamblers who enjoy playing-on-the-go are big fans of their games.

The Reactoonz Onlie Slot Theme

The action happens in a parallel universe where colourful, 1, 2, and 3-eyed aliens cascade around against a sombre, dark blue background. It is fast-moving and may seem quite complicated at first sight. But, it is easy to get the hang of and has proven to be very popular with the global online gambling community. Even though there are no Reactoonz free spins to play, there are plenty of other features to enjoy..

A Guide To The Gameplay of the Reactoonz Online Slot

This is a cascading grid-reel game, where instead of matching 2 or more symbols on a payline, you have to land 5, plus, in a horizontal or vertical line. The high payer is the pink alien. Each win charges a cell in the game’s Quantum Leap meter.

When fully charged, a Quantum feature is added to the queue, leading to 5 potential bonus features which are Alteration, Demotion, Fluctuation Implosion, and Incision.

Type of Feature What it does
Alteration Alters a low-value symbol into another symbol right across the grid. An alien symbol is chosen if no low-value symbols are available.
Demotion Destroys and makes room for other symbols
Fluctuation On each spin, a low-value symbol is selected at random and becomes a fluctuating character. When part of winning combo, 2 wilds get generated on the grid.
Implosion Turns 3 to 6 symbols wild, destroying other characters next to them.
Incision A Wild travels the grid turning all affected symbols it touches creating huge X.

The Reactoonz Online Slot Gargantoon And Giantoonz Features

When all 5 cells are fully charged the Gargantoon feature is triggered. It will award you a 3×3 random wild. It divides into 2-off, 2×2 wilds with each cascade, and on the third, it transforms into 9-off, 1×1 wilds.

The Giantoonz feature appears when 4 matching symbols come up in a 2×2 configuration. It is essentially a bigger version of the Gargantoon alien and multiplies winning combos x2.

It might sound somewhat complex, but only because it is different. The best way to familiarise yourself with it is to play a Reactoonz free slot which most Paly’n GO casinos offer.
