About The Game

Aaagggghhhhh. Do you recognise that sound? It’s the sound of Demolition destroying all your low paying symbols, which means this review is, of course, about Reactoonz. One of the earliest grid games to be released, Reactoonz is definitely one of the brightest and more colourful slots to play. If a grid full of one eyed monsters, confusing (at first) gameplay and some really good base hits are things you find enjoyable in a slot then look no further, I’ve found the one for you.

The pay table on Reactoonz is much like our past reviewed slot Tome of Madness. Wins are achieved with 5 or more matching symbols at a time, provided they are touching horizontally or vertically. The one eyed monsters are your low paying symbols and the two eyed fancy monsters are your premiums. The pink monster is your top symbol and the one you want to see plenty of. Symbols each pay for 5, 6, 7, 8, 9, 10+, 12+ and 15+ of a kind, so we’ll not go through that all but here’s what you need to know: yellow & green and red & purple monsters pay 3x bet and 10x bet respectively for 15+. Blue monsters pay 75x bet, orange monsters pay 150x bet, green monsters pay 300x bet and the pink monster pays 750x bet, all for 15+. Winning symbols are removed and new symbols fall down in their place.

If a monster fills all positions in a 2×2 square it transforms into a giant monster and with that attaches a x2 multiplier, meaning in any one spin if you land 15 pink monsters, with a x2 multiplier it pays a massive 1500x – that’s the aim of this game.

The object of Reactoonz is to fill the 5 bars which is when you are awarded the “bonus” of Gargantoon, the very large 3 eyed wild monster. Each time you fill a bar you are awarded one of four Quantum Features. The Quantum Features available are: Implosion, Incision, Demolition and Alteration. Implosion transforms between 3 and 6 symbols on the grid into wilds, and destroys all adjacent symbols. Incision plants a wild in the centre of the grid and cuts two lines through the symbols diagonally, transforming them all into the same symbol, or even better – a wild sometimes. Demolition removes all one eyed monsters from the grid. Alteration chooses one random, one eyed monster and changes all of that monster on the board to a different, matching symbol. Each of these Quantum Features are designed to help you build to the fifth bar, which is Gargantoon, so on your way you’ll have four Quantum Features. These can all be the same feature, or can be one if each, there’s no set order. Wild symbols on the grid are not affected by Quantum Features.

To further help you in your quest for Gargantoon (or Garga as most people refer to him) on any initial non winning spin you may be awarded Instability, where 4 to 8 wild symbols can drop into the grid.

Once you’ve filled all 5 bars, you’ll activate Gargantoon. He is a 3×3 sized monster and is a wild, substituting for all symbols on the grid. He divides and moves each time he is used to make a combination of wins, first appearing as size 3×3, then dividing into two 2×2 wild symbols, and finally appearing as 9 individual wild symbols. New symbols drop onto the grid before he divides down each time.

My Thoughts

Of all the grid slots available Reactoonz is definitely one of my favourites. It’s an incredibly fun game to play, and even though we’ve all felt the pain of getting one win away from Garga, most of us have also felt the excitement of getting those 15 pinks x2, which is why I love this slot so much. It’s highest possible single win isn’t too far out of reach, which makes it feel like less of a far off dream, and therefore makes the slot more enjoyable to play. Being able to hit that highest win in the base game without activating Gargantoon adds to the excitement even further.
That’s a Garga!
